Working together

Welcome to another edition of BM TRADA’s Timber Industry Yearbook bringing together articles to help you meet the current economic and market challenges head on.

As the UK economy stagnated, 2022 was a year of rising supply chain and production costs, associated increases in the price of energyintensive materials, and a suppression of the housing market and commercial construction. However, while year-on-year market comparisons show significant reductions against previous years, the outlook for 2023 remains less bleak than was expected by industry experts. Against a challenging economic backdrop, global demand for timber continues to grow and the benefits timber delivers as a construction material will continue to drive demand.

In the 2023 edition of our Timber Industry Yearbook, we look at how we can help you continue to achieve your core goals, despite ongoing economic difficulties. Whether through the direct support offered by BM TRADA’s technical helpline, or via our publications, courses and webinars, we aim to make up-to-date, targeted and demand-driven industry knowledge accessible to you all.

Technical timber knowledge

Written by our BM TRADA technical timber team, on topics to include wood knowledge, engineering, regulation, timber frame and off-site construction. New articles cover:

• wood borers

• how to buy quality plywood

• regulatory updates

• moisture in timber.

Timber structures, skills and materials

Once again, we cover key topics relating to timber structures and expand our section looking at timber as a material, to include:

• sustainability and the circular economy

• off-site construction

• engineered timber

• fire

• skills

• timber species and applications.

The timber sector in 2022

As we head towards spring, Ben Sharples looks back at 2022 and discusses the interaction our expert timber consultants, BM TRADA’s laboratories and services, and our wider group management continues to enjoy with the wider timber industry.

It was more than impressive to see timber markets rally to pre-pandemic numbers during the first half of 2022, despite the impact of the Ukraine crisis on timber imports, issues caused by the Northern Ireland Protocol and import warnings around birch plywood from the Far East. As we headed into the winter months, we faced a decline in demand, a reduction across imports and an impact on prices. However, the increase in energy prices inflated the value of timber products.

We are taking a stand for a better built environment

While events continued to be affected by the lockdown lull in the early months of the year, the BM TRADA team was able to attend Futurebuild in Excel, London on 1–3 March 2022. Many of our technical consultants presented talks and our marketing team hosted a stand. It was very enjoyable to get out and about to meet some of our customers face to face once more.

BM TRADA and the Element Group

In 2022, TRADA merged with the Timber Trade Federation to become Timber Development UK (TDUK) and BM TRADA’s managed services contract with TRADA ended. Throughout the year, BM TRADA continued to serve the timber industry as it always has, and always will. Everything BM TRADA does is designed to help our customers to develop better products and processes; get their products to market on time; save time and money; and minimise the risk associated with product and process development as well as product production.

Today, BM TRADA is part of the Element Group. Element is the fastest growing testing, inspection, certification and calibration business in the world. >>

Carbon and timber in construction

In May 2022, as part of our remit to publish sector-specific information, we published a brandnew Wood Information Sheet with the help of Toby Maclean, Allt environmental structural engineers.

WIS 2/3-72 Carbon and timber in construction for building designers discusses key sustainability topics in relation to timber in buildings: carbon emissions, carbon stores and the complex relationship between timber in the built environment and the forests it was sourced from. It also provides methods to minimise carbon use and to maximise the carbon store and explains procedures for calculating the embodied carbon in a building according to a life cycle assessment (LCA).

Embodied Carbon Bill

The handy new Wood Information Sheet on carbon in timber construction became available just prior to Jerome Mayhew’s reintroduction of the Embodied Carbon Bill in the second half of June. The motion follows on from a campaign by the construction industry for the inclusion of a ‘Part Z’ in the Building Regulations and aims to ensure legal limits are in place to reduce embodied emissions. It requires the construction industry to report on whole-life carbon.

Debated by the House of Commons at length in November 2022, the bill failed to achieve government support, with the then UK Government. DLUHC Minister Dehenna Davison MP noting that SMEs were struggling economically as it was, and suggesting the time wasn’t right for such a regulatory change. However, the sentiment of the bill does have the full support of the UK Government and will be revisited by Parliament at a more opportune time.

BM TRADA and Warringtonfire marked 50 years of fire testing

In June 2022, we celebrated a major milestone, with the 50th anniversary of fire testing at Warringtonfire’s High Wycombe laboratory in the UK. In June 1972, the very first commercial fire test was undertaken at the newly completed testing laboratory. Since then, Warringtonfire has remained at the forefront of the testing industry by building a world-class

team of experts and collaborating with trade associations and standards committees. Our team of technical experts continue to play a pivotal role in raising standards in the fire protection industry, making tomorrow safer than today.

Now thought to be the UK’s oldest existing fire resistance testing laboratory, Warringtonfire’s impact can be found every day, in offices, airports, schools and hospitals.

New graduate engineering scheme

Coinciding with the 50th anniversary of fire testing at Warringtonfire’s High Wycombe laboratory, BM TRADA formalised its approach to graduate recruitment at Warringtonfire. The two-year programme comprises four rotations through key areas of the business: Reaction to Fire Testing, Fire Resistance Testing, Technical Assessments and Quality, prior to a three-week ‘flexible placement’ to focus on a selected topic. The new graduate engineers also undertake external IFE Level 1, 2 and 3 qualifications.

In 2022, the scheme received over 200 applications for just four places from recent graduates with a minimum of a 2:1 degree classification in a STEM subject. The new graduate scheme will continue in 2023.

Timber lab refurbishment and fastener and fixing testing

In August, BM TRADA unveiled its modernised timber laboratory following an extensive refurbishment and investment. The three-month long revamp at its High Wycombe facility brings significant savings in energy usage and included a complete overhaul of the laboratory’s layout. The space is now divided into two dedicated areas, with one room designated for timber inspection and timber species analysis, and the other room for woodworking and timber testing.

Alongside the new layout, the laboratory was stripped down and a host of new equipment installed. This includes new storage, dust extraction units, boil tanks and water baths for woodwork testing; and a range of microscope equipment to analyse timber specimens. We also fitted new tools and rigs for fastener and fixing testing for structural timber connections, which will be operated under Element Material Technology’s Warringtonfire brand.

As well as timber construction, we’ve witnessed more demand for timber species verification from a wide variety of markets. We house one of the largest libraries of referenced timber specimens, known as a xylarium, in the country at our High Wycombe site. With our new laboratory and equipment, we can continue improving on this service and providing even more accurate advice and knowledge on different types of wood species. >>

Buildings Safety Act, Fire Safety Act and RRFSO

This year, the industry had to embrace an update to Approved Document B, which now permits structural timber for use in the external walls of all buildings up to 18 metres in height. This new package of improvements was introduced to strengthen and clarify building regulations and fire safety guidance as part of wider reforms.

The introduction of the Fire Safety Act 2021, the Fire Safety (England) Regulations 2022, and changes implemented by the Building Safety Act 2022 brought amendments to The Regulatory Reform (Fire Safety) Order (RRFSO). The updated RRFSO now takes a broad view of responsibility, and some may not realise they have legal responsibilities for fire protection. The changes impose important duties and responsibilities for protection of people from fire in all premises other than private homes.

BM TRADA’s fire experts worked hard all year to deliver updates on the implications of these regulatory changes, which are covered in several editorials within these pages.

CLT and moisture research now freely available

Summarised in our 2022 Timber Industry Yearbook, our technical consultancy team worked with Stora Enso to report on research carried out on The moisture of dynamics of crosslaminated timber. The two-part research project looked at both wetting risk during construction and drying rates. Results allow us to determine moisture distribution behaviour. In October 2022, the important research results were presented at UK Construction Week.

CE to UKCA marking

The UK Government’s Department for Levelling Up, Housing and Communities (DLUHC) updated its guidance on the Construction Products Regulation in Great Britain and Northern Ireland on Friday 9 December 2022. The new guidance reflects the Government’s decision that it will continue to recognise the CE mark on construction products for another 2.5 years, to allow businesses until 30 June 2025 to prepare for the UKCA mark, which is a change from the 31 December 2022 date stated in previous guidance.

DLUHC stated, “Our intention is to end recognition of the CE mark in GB on the 30 June 2025. Current rules, which allow for continued recognition of the CE mark, will remain in place until legislation is laid to end recognition of the CE mark.”

We will continue to offer services for UKCA marking during the extension period and will assist with completing any programme of works that you are currently undertaking.

Webinars and courses

Thanks to all participants who attended one or more of BM TRADA’s webinars and courses in 2022. Your participation led to record registrations with webinar attendance routinely hitting levels around the allowed maximum of 1,200 at the beginning of the year. Even as we all became more able to get back to normal post-lockdown, you continued to enjoy regular online presentations from both our internal experts and external guest speakers. Courses also did well, and we were very happy to add a third date for our Timber Frame Construction training course when the original two scheduled dates sold out.

We look forward to extending the invitation to further webinars and courses in 2023. We will continue to keep you all up to date as our sector evolves, introducing new topics and presenters as possible while maintaining the BM TRADA tradition of sharing critical foundational knowledge to anyone interested in learning about timber and construction with timber. n

Celebrating outstanding use of timber

This year has produced another crop of worthy winners across key 2022 building design awards such as the RIBA Stirling Prize, RIBA National and Regional Awards, Wood Awards and IStructE Structural Awards. Here, we showcase just a few of them...

RIBA Awards 2022

In June 2022, the Royal Institute of British Architects (RIBA) recognised its selection of 29 of the UK’s best new buildings as winners of the 2022 RIBA National Awards for architecture. Key trends highlighted by this year’s winners include venues that unite communities, future forward housing and the restoration and adaptation of existing buildings.

At the awards announcement ceremony, RIBA President, Simon Allford said, “At a time when we need to bring people together and plan for a sustainable future, this year’s RIBA National Award-winning buildings offer much hope. This is a powerful collection of buildings that show, despite the economic, political and social turmoil of the last few years, how great architecture can emerge even in challenging conditions.”

Stirling Prize

RIBA awards its Stirling Prize to the building judged to be the best and overall winner in the UK. This year, the award went to The New Library, Magdalene College by Níall McLaughlin Architects, as featured on our front cover.

“A unique setting with a clear purpose – The New Library at Magdalene College is sophisticated, generous, architecture that has been built to last […] The light-filled, warm-wood interior lifts spirit and fosters connections […] Well-designed environments hugely improve student success and wellbeing,” said Allford.

Mæ architects, who were responsible for the Sands End Arts & Community Centre on behalf of Hammersmith & Fulham Council, explained to RIBA that, “The pavilions are constructed in CLT and glulam, with green stained timber panelling. The CLT frame and woodwool slab infill are left unfinished at ceiling level, heightening the feeling of light from high-level clerestory glazing. The sustainably sourced CLT frame not only sequesters carbon but it’s also lightweight, reducing foundation requirements.”

Smaller, private projects featuring outstanding use of timber and wood products that received awards included Mews House Deep Retrofit by Prewett Bizley Architects and Pitched Black by Gruff Architects. The latter features a first floor clad in black timber boards and pitched 10 degrees away from the boundaries which, according to the architects, diminishes the perceived mass of the building from neighbouring gardens. >>

IstructE’s Structural Awards 2022

This year’s Institution of Structural Engineers (IStructE) Structural Awards followed new judging criteria based on four key areas covering technical innovation, professional advocacy, social value and environmental impact – process, profession, people and planet! Ten winners were selected from a shortlist of 41 structural engineering projects.

Supreme Awards

Supreme Awards for Structural Engineering Excellence were presented to two projects that, while not relying on timber, demonstrated innovative and low carbon construction approaches. The HYLO project by Horden Cherry Lee Architects, which added 13 storeys on top of the original 16-storey building, received the Award for full exploitation of an existing structure to maximise retrofit potential. The Award for advancing the structural application of low carbon materials went to The Arc at Green School in Bali, Indonesia by Ibuku. Incorporating pioneering bamboo shell structures that span arches 19m wide by 13m high, the build relied on extensive testing to justify its design due to the variable material properties of bamboo.

Largest timber structure in Asia

The Award for structural elegance through integrated design and construction went to Tianfu Agricultural Expo Main Hall. At over 75,000m2, this is the largest timber structure in Asia. A series of five vaults use unique Vierendeel-inspired (after Arthur Vierendeel truss design) timber chord and steel trusses with ETFE membranes to achieve clear spans up to 110m and heights up to 44m.

“Efficient, thoughtful and collaborative engineering at its best,” remarked one of the judges.

Your timber questions answered

Phil O’Leary tackles just a few of your questions from BM TRADA’s popular 2022 webinar series.

Q: What is the difference between ‘early wood’ and ‘late wood’?

Early wood (generally lighter coloured growth rings on the end grain of softwood and temperate hardwoods) develops during the early part of the growing season (spring wood). Cell walls are relatively thin and have larger lumina (cavities in individual wood cells) conducting water/ sap and nutrients up and down the tree. This is one of the primary functions of lumina.

Late wood (darker growth rings) forms later in the year (summer wood) as the tree lays down cells with thicker walls and smaller lumina, to provide strength to the trunk or branch of the tree.

Q: What does ‘dote’ mean in terms of defective timber?

A general term for fungal decay present in timber –sometimes referred to as incipient decay – and often found as localised patches/pockets of decay.

Q: How can you have more than 100% water content in a tree or timber?

When a tree is felled, it often has a relatively high moisture content because the tree is living and contains water taken from the ground as part of its growing process. Moisture content is expressed as a percentage of the dry weight of the timber. Therefore, if the weight of the water is more than the dry weight of the timber, the moisture content will be more than 100%.

Q: How can you distinguish mechanical failure vs moisture shrinkage as the cause of timber splitting?

A stress failure in the timber is usually identifiable by some key characteristics such as cross grain failure, breaks in the timber fibres and deformation of the member due to some form of overloading.

Fissures are a result of drying/shrinkage in a piece of timber. The fissures will follow the longitudinal grain direction and run at right angles to the growth rings across the cross-section.

We recommend you always consult with an expert if you feel there may be a structural issue for a timber member or structure.

Q: What is the difference between Use Class and Service Class?

Defined in British and European Standards, Use Classes (UC) are based on differences in environment exposures and provide a guide to the risk of biodegradation due to decay and insect attack to timber components depending on their end use/application. The five classes are UC 1 to UC 5 with UC 1 being the least at risk, ie interior, dry. Use Class 4 is a situation where timber is in ground contact and/ or fresh water. Determining the Use Class can then help identify how naturally durable a timber species needs to be, or what level of preservative treatment is required to achieve the desired service life.

Service Class is a classification used by structural engineers/designers to determine the structural performance for timber elements to be used in construction based on the in-service conditions. The structural capabilities of timber change depending on its moisture content. The three Service Classes (1, 2 & 3) are determined by the moisture content of the timber which corresponds to the relative humidity and temperature expected in service, defined by Eurocode 5 (EN 1995-1-1).

Q: Is there a way to preserve timber’s natural colour without adding pigment or stain?

This is a common question that we get asked at BM TRADA, whether on the technical helpline or Q&A sessions at the end of training courses and webinars. There are a number of clear or varnish coating products that claim to have UV blockers or inhibitors. However, the reality is that these still provide relatively short-term protection to the timber surface from UV damage (greying) and will need to be reapplied at short intervals, particularly on south-facing elevations. BM TRADA does not recommend clear coatings for external timber because of the high maintenance cost caused by short life span and difficult preparation for new coating. The short answer is ‘no’. Coatings with pigment matching that of the natural timber colour remain the closest way of achieving a natural timber appearance.

What is eating my timber?

Concerns about insect infestation in wood can arouse panic in the minds of many construction professionals, but expert Nick Clifford is happy to let you know the risks are not often as high as you may first believe.

There are, in fact, only a small number of wood-boring insects common in wood in UK buildings: the common furniture beetle (Anobium punctatum), deathwatch beetle (Xestobium rufovillosum), powder-post beetle (Lyctus brunneus), house longhorn beetle, (Hylotrupes bajulus), wood wasp (Xiphydriidae), and pinhole borer beetle (Platypodinae).

For their larvae to hatch and grow, adult females select wood with suitable moisture content and foodstuff in which to lay eggs. Most wood borers are confined to wet wood and are forest pests rather than pests of wood in buildings; others can only develop in certain wood species or even in certain regions of the tree, ie sapwood. This means that all wood can be protected from infestation by drying, excluding sapwood, selecting species naturally resistant to attack or treating with an insecticide.

How to manage the risk of wood-borer infestation

1. Purchase timber that was debarked and dried quickly after harvesting

2. Purchase seasoned or kiln-dried wood with reduced moisture content – but be aware that even properly dried wood can be infested if stored uncovered

3. When buying wood, inspect it for bore-holes, frass and other signs of insect damage

4. Consider using timbers that have been chemically treated under pressure for structural joists or trim

5. Control moisture during storage, as well as throughout and after construction. Larvae need more than 15% moisture to develop

6. Keep exposed wood covered in polythene or freshly coated with paint, varnish or stain

7. Stack firewood and any unprotected timber outside and away from outer walls

8. Immediately treat any timber with signs of infestation

9. Identify any beetles found, assess the damaged timber and evaluate the risk to other timbers

10. Use the life cycle of the beetle to trace back liability

Top tips on how to buy good quality plywood

We might all think we know what plywood is, but the facts may surprise you. Gavin Fidler clears up some common misunderstandings about what plywood actually is before outlining some tips for buying quality plywood that can be used safely structural applications.

What is plywood?

The term ‘plywood’ is occasionally used as a ‘catch-all’ term for all wood-based panel products. However, just like other wood-based panel products such as particleboards, oriented strand board (OSB) and fibre building boards, plywood is a distinct product with specific features.

Plywood consists of an assembly of layers (plies) glued together, with the direction of grain in adjacent layers usually at right angles – a technique referred to as cross-graining. There are two types of plywood:

• Core plywood (or plyboard), such as blockboard and laminboard, have a central core of wood strips or other materials, with two or more outer wood veneers.

• Veneer plywood plies are all made of veneers orientated with their plane parallel to the surface of the panel.

Find out more about plywood and other wood-based panel products in our Wood Information Sheet: WIS 2/3-23

Introduction to wood-based panel products.1

What to look for when buying plywood

At the design phase, specifiers can determine performance standards by limiting the acceptable levels of knots, core gaps or voids, splits or surface flaws in the material. Plywood performance also relies heavily on the quality of glue used and, as market forces drive prices downwards, manufacturers make cost savings by using cheaper glues. Purchasers should be aware that it is visually impossible to tell a good plywood glue bond from a bad one as glue dyes can be used to disguise a poor-quality glue.

How to specify plywood for quality

When buying plywood, the details provided by a third-party certification stamp can be key to preventing the potential misunderstandings around quality that a simple visual inspection can raise. The stamp will include information on the grade or class of that product.

There are currently a number of European Standards and British Standards which deal with plywood grades.

• General European Standards for plywood:

o BS EN 635 which deals with the surface appearance2-6

o BS EN 636 which deals with the specifications7-10

• British Standard for marine plywood: BS 1088.11

Most plywood used in construction work will be more reliant on glue bond quality than aesthetics. In the UK market, reference is frequently made to the class of the plywood, which relates primarily to the bond quality achieved rather than the durability of the timber veneers.

What plywood to use and where

Class 1 plywoods are non-structural and will typically be used for interior furnishings only.

Class 2 plywood applications are typically where the boards will be protected from wetting but may be exposed to some degree of moisture during or following the construction phase. This can include floor decking, roof sarking and wall sheathing.

Class 3 plywoods are able to withstand full exposure to external weather conditions, but may not be when in ground contact. These boards are useful for external cladding, site hoarding, signage and playground equipment.

Class 2 and Class 3 structural grades are capable of carrying structural loads and will be marked with an ‘S’, eg BS EN 636-2S.

Marine plywood contains Class 3 glue bonds but is also fabricated using naturally durable timber species. This means the boards can resist fungal decay, making them useful in environments where they are permanently exposed to wetting, including external environments that are in contact with the ground.

Material sold as marine plywood without reference to BS 1088 may not be of the same quality.

Top tips on how to buy and build with good quality plywood

1. Understand the difference between plywood types.

2. Never judge plywood purely on how it looks.

3. Look out for, and learn to read, certification stamps.

4. Use the correct class of plywood for each application to avoid failures.

5. Check that the right quality of glue and timbers have been used to manufacture your plywood.

6. Inspect plywood boards for surface damage, warping or signs of delamination.

7. Examine the edges for voids and look for uniform thickness across veneers.

8. Keep hold of your specifications and Declaration of Performance (DoP) documentation – these will cover you in cases of failure.

9. Keep a sample of your plywood for testing in case of failure.

10. Call the BM TRADA helpline for advice: 01494 569601.

How to I know my plywood is strong enough?

Design to Eurocode 512 requires characteristic design values for the product based on testing. For structural wood-based panels, these values are declared in the manufacturer’s Declaration of Performance (DoP) that is prepared before the product is placed on the market. There is an obligation for all parties in the supply chain to ensure this technical information is passed along the chain, encompassed within the UKCA/CE documentation.

Where a specific strength property is required, purchasers should include this requirement within the purchase specification and check the UKCA/CE documentation and the associated DoP for the goods received at delivery to ensure that specification is met.13

Is the plywood I bought and used going to fail on site?

Where plywood fails in service, laboratory testing can be undertaken to confirm whether the plywood was of the correct grade and of an appropriate quality. At BM TRADA, we have seen many examples of the wrong type or quality of plywood being used on site and subsequently failing.

BS EN 314 (parts 1 and 2)14,15 set out the methodology for plywood glue bond testing using the ‘shear test method’, where plywood test specimens are cut, exposed to moisture via a pre-treatment process which varies

according to glue bond class and then clamped in a testing machine where loading is applied in tension until failure. Once the specimen fails, both the failure load (in Newtons per square millimetre) and failure mode (wood fibre failure or glue failure) are calculated and rated against minimum performance requirements.

By retaining a small sample of any plywood you use in your construction, you will be able to have that product tested if the worst happens.

What to do if your plywood fails in service

As part of a plywood manufacturer’s factory production control system, they should be undertaking glue bond testing on batches of plywood to monitor and confirm performance. This testing is normally carried out by the manufacturer in their own laboratory but may be audited as part of any certification they hold.

Some UK plywood importers and distributors choose to undertake additional plywood testing, and TDUK requires its members to conduct third-party testing to verify the quality and performance of certain types of plywood that they place on the UK construction market.

The majority of plywood testing which BM TRADA undertakes relates to either failure of plywood in service or additional conformity testing for UK plywood importers. >>

How to inspect and assess used scaffold board

Timber

Rare is a construction project that does not use scaffolding and scaffold boards. Enabling workers to access heights, timber scaffold boards are such a common component of most building sites it is easy to take them for granted. But failure of a scaffold board can lead to serious injury and loss of life. So, the integrity of timber scaffold boards is critical to health and safety on any building and construction site.

Assessing scaffold boards will ensure longterm safety

Knowing how to store timber scaffold boards correctly and how to carry out accurate inspection and assessment of those same boards will enable scaffolding companies and scaffolding contractors to keep boards in useful service despite appearances. Understanding inspection techniques, assessment specifications, and how to confidently reissue or withdraw scaffold boards from service will ensure worker safety and the long-term reputation of both supplier and contractor.

Every single timber scaffold board must be safe, every time

The average scaffold board is a well-trodden timber, subject to regular tear down, transport, storage, set up and reuse – over and over again. Often hired out to short turnaround project sites, the average board will quickly look battered and grubby.

During a busy working day, construction workers need to be able to assume that a scaffold board will still be strong enough to stand on safely even if it is several floors up on the exterior of a windswept, weather-beaten building under development or refurbishment. It is, therefore, a critical responsibility of anyone buying or hiring scaffolding, or managing a site with scaffolding, to ensure that every single scaffold board in use on that building site is fit for purpose, every single time it is put into use.

To ensure the maximum life of the scaffold board it must be checked regularly. Providing part of the surface or platform in scaffolding, scaffold boards must be supported at appropriate points along their length to enable them to bear the weight of anticipated loads.

New timber scaffold boards must meet standards

A scaffolding supplier must make sure each scaffold board meets the required strength specifications. New scaffold boards are cut to size, inspected and graded using British Standard BS 2482:2009.1

If you buy new scaffold boards, the supplier must be able to supply the paperwork and compliance marks to demonstrate those boards comply with the British Standard. However, as a scaffold board then works its way from one site to the next, it may undergo a quick clean and cursory inspection by potentially untrained eyes before being unceremoniously stacked for transport and storage. It is, therefore, up to you to carefully and knowledgeably inspect and assess each and every scaffold board again, before they are sent out for reuse.

While the requirement from end users is to use BS 2482 boards, some companies continue to use non-standard methods and even ungraded boards. Since 2017 the National Access & Scaffolding Confederation (NASC) audits only

Timber scaffold boards are graded for strength rather than appearance.

scaffold boards may be scuffed, worn and covered in dirt, but are they still strong enough and safe to use? Phil O’Leary explains how to maximise the service life of your scaffold boards while preventing health and safety failures on your construction site.

accept the use of scaffold boards that comply with BS 2482. BS 2482 boards will have original end bands carrying the full marking requirements of the standard.

Even with intact end bands, a used scaffold board taken from storage might have picked up damage since its previous inspection. So, the ability for hands-on staff to knowledgably reinspect all boards is essential for a scaffolding company or contractor to get the best use from its scaffolding boards while ensuring safety levels are maintained.

Timber scaffold boards are graded for strength rather than appearance

Timber scaffold boards are most often made from European whitewood and are graded for strength rather than appearance. This grading allows for a certain number of visual defects such as knots and wane (bark or insufficient wood at a corner or along an edge, due to the curvature of the log) within defined limits But how can you tell when visual defects exceed those limits? When is a split, crack or fissure excessive? When can surface contamination, saw cuts or other mechanical damage make a board unsafe to use? When does the natural distortion of an organic, timber plank become dangerous warping? Can a surface fissure be simply cut out or must the entire timber scaffold plank be rejected? If those boards accidentally got wet while in storage, how can you tell if they are still safe to use? Must all damaged boards be discarded or can some be restored?

Change is afoot: streamlining standards across construction

BM TRADA technical expert, Hugh Mansfield-Williams, and structural timber engineer

Keerthi Ranasinghe, are both members of several standards committees delivering guidance for the timber industry. Here they discuss strategic change facing that industry.

It is always risky to try to predict the future, and what follows is based on expert understanding around changes in UK timber and building industry Eurocode 5 yet to be published. So, while this article is somewhat speculative, I believe the time is ripe to lay out some of the prospective changes which timber and construction professionals might expect in the near future.

An overview of the next two years

While the new Eurocode 5 will not be published within the next two years, the general principles around what changes will be legislated by the various standards committees at a European level have been reached. It is only the technical details behind these changes that is still outstanding which, in the most part, can hopefully be resolved without the need for more voting. However, if technical details do need to go through a vote at the European level, the UK committee would then be able to adopt these agreed changes on principle. There is little reason to believe the process of publishing the new standard will be delayed.

Assuming the agreed changes are indeed adopted, we might carry out some reasonably qualified speculation.

Key changes to technical standards in discussion

Upcoming changes in regulation will be more akin to those currently practised in the steel industry. Engineers designing timber frame for the first time but with experience in steel or concrete construction will have a smoother transition. They will recognise some of the new methods coming through.

For the past 78 years we have all worked on the principle that there are only three environmental conditions to take account of: the internal heated environment, the internal unheated environment, and the external environment. Now, we shall be introducing a fourth, the waterlogged environment. This will include, for example, piling, which has been managed previously within the external environment. This distinction is an important one as timber in a waterlogged external environment behaves very differently to timber in a non-waterlogged external environment.

Other changes will consider the durability of fasteners such as nails and other fixings. The current Eurocode 51 states that fasteners used in external environments are to be coated with some form of anti-corrosion treatment. New Eurocode 5 standards will be aimed at a broad audience and give far more exacting technical and engineering details around the types of coatings required under certain conditions, what will need protecting and what length of nail should be treated, among other details.

In 2004, we thought we had resolved the issues around floor vibrations in timber frame buildings when the 1995 Eurocode 5 standard method was published. Since then, houses have been designed and developed using this method and – as an industry – we now know the original method can be improved upon. This new understanding will be incorporated in the revised Eurocode 5.

The evolution of technical standards

The underlying principle of any technical standard is that it needs to reflect the state-of-the-art. Standards must, therefore, evolve. Lessons learned from what has been practised in the industry must feed back into Eurocode 5. Standards do not lead the industry. Good industry practices must lead standards. So, these new developments under discussion today are a result of change in the industry. Some new ideas will have worked. Others will not have.

Over the past ten or fifteen years, methods within the previously published technical standards have been tested in the real world. Universities across the world have also carried out cutting-edge academic research. Knowledge gained in the past decade and a half must now be integrated into our guidance and reflected in the new technical standards.

Generally speaking, the average industry standard will have a lifespan of only five years in its original form. After that initial period, the relevant standard’s committee will take a look at it and make amendments where applicable. These amendments will then be valid for the next ten years, although will also be included in the overall standard’s review after only five years again.

Can the timber industry learn from concrete and steel methodologies?

Timber, as a material, is produced by organic process and behaves quite differently from steel or concrete. When compared with other construction materials, we must accept that timber is a very different beast.

It is becoming more important to align construction methodologies across materials, including timber, steel,

concrete, brick, aluminium, and glass – anything you might use to build with. The role of a standard is to bring alignment across construction industries to enable the regulatory framework to encompass all materials. The ability for architects, designers and developers to streamline best practice across all construction is what standards committees work to achieve. n

Part L and timber frame

Recent changes to Approved Document L aim to reduce energy use in buildings. Here Robin Lancashire looks in more detail at how designers and contractors can mindfully apply this new guidance while assuring safety and performance benefits without conflict.

Timber frame buildings have evolved over many years in response to changing thermal performance requirements in Building Regulations. Historically, timber frame buildings had substantially better thermal performance than their masonry counterparts; even early post-war ‘modern’ timber frame buildings contained some form of insulation between studs, where their masonry counterparts did not.

However, in more recent decades requirements to achieve ever tightening thermal performance targets saw that gap decrease, and today the U-values (thermal performance) of masonry and timber frame buildings will be governed by U-values in Approved Document L and the outcome of Standard Assessment Procedure (SAP) calculations.

Early ‘modern’ timber frame external walls used approximately 90mm deep timber studs, but in the early 2000s, the industry increased wall thickness to 140mm to incorporate more thermal insulation between the studs. After the updates to Approved Document L in 2010, service voids with additional insulation or reflective vapour control layers were generally adopted to help further improve U-values as well as offering enhanced air tightness performance.

The recent changes to Approved Document L were published in 2021 and came into effect in June 2022. These changes introduced prescriptive guidance above and beyond the SAP calculation/U-value targets. While the improvements in U-values and SAP targets are an incremental step change, building upon previous revisions, the prescriptive guidance is new and quite different to the information previously contained in Approved Document L.

BREL report

One overarching notable change is the introduction of drawing reviews and site audits encompassing items such as installation of insulation, thermal bridging and airtightness. During the design stage, the designer and installer should review drawings to check that prescriptive guidance in Approved Document L has been met and that the details are robust and buildable. During construction, photographic records should be taken of site works before they are enclosed by following trades. The final Building Regulations England Part L (BREL) report should then be provided to Building Control and the building owner to show that work complies with energy efficiency requirements.

Plan - typical timber frame external wall construction as it exists today.

An example of timber frame external walls, pre-insulated in the factory and lined with a reflective vapour control layer and battens to create an internal service void.

This review and reporting may offer advantages for off-site construction, and for building designers working with timber frame manufacturers. Installing items such as insulation and airtightness layers in closely controlled factory conditions may make control of these works easier and reduce the risk of construction defects on site, for example.

Thermal bridging

Timber frame buildings have historically had reasonable thermal bridging performance. Repeat thermal bridges (such as wall studs) are factored into U-value calculations, and nonrepeat thermal bridging has generally been reasonable when compared to other construction materials (due to timber’s reasonable thermal conductivity). Under the recent changes to Approved Document L, there are a number of prescriptive guidelines which have the potential to result in considerable changes to timber frame.

Firstly, it is suggested that insulated plasterboard can be installed to the inside face of external walls to help further reduce thermal bridging from timber studs. While insulated plasterboard can provide that function, there are several potential issues with this type of construction. At present there is limited availability of suitable fire resistance test evidence for insulated plasterboard products used on timber frame which may limit or prevent their use. In addition, there are potential order of works issues with the installation of services, service voids and vapour control/airtightness layers.

Where designers wish to incorporate continuous layers of insulation in timber frame external walls, it is generally more sensible to install a separate continuous layer over the inside or outside face of the studs prior to the installation of further finishes. However, these methods also have their advantages and disadvantages, including availability of fire test evidence, order of works and installation of cavity barriers. Designers must remember that there can be unintended consequences to their choices – a good choice for thermal performance reasons may bring with it added complications to fire performance and buildability, and it is important that these potential issues are identified and mitigated at the design stage.

Secondly, Approved Document L suggests that in all construction types, insulated cavity closers should be installed around window and door openings. In timber frame, cavity closers must act as fire resistant cavity barriers. Historically, timber battens at least 38mm wide have been used to both close the cavity and act as a fire resistant cavity barrier, although it is unlikely that these would be considered ‘insulated’. Therefore, it may be necessary for the industry to move away from timber battens and instead use polythenesleeved mineral wool cavity barriers, or other proprietary insulated cavity barriers/closers (providing they can provide the required fire resistance). Polythene-sleeved mineral wool cavity barriers are commonly used in other locations in timber frame construction, but their use around windows will have a knock-on effect on window installation details for air and moisture tightness and for order of works. The industry may need to adopt a different approach to weather-sealing windows and doors into external walls, as historic detailing is not compatible with flexible cavity barriers.

Airtightness

Timber frame buildings have always offered good airtightness performance compared to other construction methods. The inclusion of a vapour control layer to the inside face of external walls can also be used as an effective air barrier, with lapping of membranes at junctions helping to reduce or eliminate unintended air infiltration into the building. >>

Examples of continuous external or internal insulation to reduce thermal bridging. These offer potential advantages over the insulated plasterboard suggested in Approved Document L.

The updates to Approved Document L now discuss the use of self-adhesive tape to seal junctions and laps in the vapour control layer/air barrier. However, in our experience, the use of self-adhesive tape should be minimised as site application of tapes can be problematic and may not provide a longterm robust seal. Conditions on site are often less than ideal, and surfaces which are too cold, wet or dusty can limit the performance and robustness of adhesive-bonded tapes.

Instead, junctions in the vapour control layer/air barrier should be mechanically lapped over studs and rails and then trapped and clamped by the service void battens. These types of mechanical laps are likely to provide a more robust and long-term seal than tapes, as well as being less reliant on quality of application. Combining mechanical lapping with the addition of taping may offer superior performance to either, in isolation.

Approved Document L now also states that the air barrier should touch or be in contact with the insulation layer. The intention of this guidance is to reduce the likelihood of thermal bypass; that is movement of cold external air through the wall into a void or space between the air barrier and insulation on the warm side of the wall. This guidance will not be problematic for walls fully filled with ‘soft’ insulation materials (such as mineral wool, cellulose fibre, or other natural batt or quilt products). It may, however, require a

change to material specifications where rigid board insulation products are used, as these often do not fill the full depth of the stud voids thereby leaving gaps, which should now be avoided.

Summary

In summary, the recent changes to Approved Document L are a welcome step further along the path to reducing building energy usage (with the associated savings in cost and carbon emissions in use). However, as is often the case, building designers must carefully consider the potentially conflicting Approved Document sections and be mindful of potential unintended consequences which may inadvertently compromise some other aspect of building performance or safety. n

Moisture and timber in construction: an introduction

Lewis Taylor and Andrew Pitman introduce timber’s relationship with water, equilibrium moisture content, the fungal decay threshold, variation in the movement of timbers and the ways in which we must account for these factors in building design and construction.

It’s vital to understand the relationship between timber and water. Understanding the implications of too much moisture in construction timber is probably the issue that BM TRADA experts see most difficulties with, and mistakes made, during building site visits.

Wood loves water

Timber is a hygroscopic material. This means wood is waterloving and absorbs water when exposed to rain or leaks. It is also important to understand that wood also absorbs and loses water in the vapour form; water that occurs naturally in the air.

While things like oxygen and nitrogen content are constant in the air around us, water vapour content – or relative humidity –so varies with the time of day. Over time, this inconsistency in relative humidity impacts the moisture content at the surface of exposed wood.

When constructing with wood, it’s very important to consider all potential moisture sources. These include less obvious sources such as humidity within the building, as well as rainwater outside. For example, the humidity in bathrooms and wet areas may differ from that in other regions of buildings.

Moisture in wood

Wood grows in a series of structures which, when magnified using a microscope, look like stacks of drinking straws. In a standing tree, the wood cell walls surround vertical hollows, called lumina, that are filled with water. However, when a tree is felled and turned into logs, moisture will be found in both the lumina and the cell walls of the wood. Whether air-dried or kiln-dried, the

water is then removed from the lumina and from most of the cell walls, although even dry wood will contain some moisture.

A cubic metre of freshly felled and dried oak, for example, will retain around 12% moisture content, which is around 77 litres of water. So, even in a heated room at 20°C, under 65% relative humidity, the same oak used in the construction of that room will retain 12% moisture content.

Too much moisture in wood

Problems with construction timber arise when additional moisture is allowed to penetrate the wood. If allowed to stay wet for a period of time, construction timbers can become distorted, wood panels can warp and fungal decay can set in. This can occur during storage and installation, or once construction has taken place, and can result in structural weakness.

Timber is an organic material that will expand and contract with moisture content. Over time, construction timbers move. A welldesigned building must account for this expected movement.

For example, if a tongued and grooved system of external cladding boards is installed without space for the wood to swell in wet conditions and shrink as it dries, the cladding can lift away from its supporting frame.

Predicting timber movement

Happily, after many years of research and experience within the industry, we are able to understand the relationship between water and wood and predict how different timbers will behave when exposed to differences in relative humidity. We know that, as relative humidity increases, the equilibrium moisture content of wood also increases. Different timber species are now classified into three classes relative to how much they will shrink and expand under different moisture levels.

The equilibrium moisture content (EMC) of wood is the moisture content that wood will have when exposed to the relative

Timber technology

Timber frame

humidity at a set temperature. With this information, we can predict how the wood will behave under any set of conditions.

For example, in an air-conditioned building, the typical moisture content of wood can be as low as 7% EMC. Whereas in a building where the heating is only turned on for short periods, the EMC of wood will be nearer 12–16%. Outside in the UK, however, during wet, winter months, the EMC can rise to around 20%.

Fungal wood decay only occurs when the level of moisture in timber rises above the levels needed by the fungi to colonise and begin breaking down the wood. This needs to happen over a sustained period. This threshold is typically around 23% moisture content and is known as the ‘fungal decay threshold’.

Drying wood

When we first start drying wood, we’re taking all the water out of the hollow lumina. This will get us down to around 30% moisture. The point where all the space in the cell walls of a piece of wood is full of water, but the lumina are dry, is referred to as the ‘fibre saturation point’. Critically, when the moisture content in timber is less than the fibre saturation point, any changes in moisture content will cause the wood to shrink as the moisture levels drop or expand as they increase.

The long, vertical cell walls of wood mean that when those cells fill with water, they expand outwards, getting thicker rather than longer. This means that timber doesn’t naturally move much longitudinally, along the length of what was the tree trunk. So, while movement in the radial and tangential directions can be as much as 3% and up to 8% respectively, movement along the length of the same timber will be less than 1%. This means it can be used for fence posts and freshwater pilings, even in wet conditions.

Classification of timber

When defining the movement of timbers in the 1960s and 70s the Forest Products Research Lab classified timbers into three separate classes based on an average of how much they change dimension with moisture content within the radial and tangential directions. So, classifications are divided into three:

1 Large movement timbers will change by 1% in dimension for every 3% in moisture content.

2 Medium movement timbers change by 1% in dimension for every 4% in moisture content.

3 Small movement timbers change by 1% in dimension for every 5% in moisture content.

This only refers to shrinking and expansion below the fibre saturation point, above which the timber dimensions remain unchanged.

Designing for timber movement

Understanding these movement classes, and knowing the anticipated change in moisture within which construction timbers must function, allows designers to select timbers for their durability under those conditions, predict the movement of individual components and design the construction to allow for any shrinkage or swelling. For some applications, such as exposed decking with narrow gaps between boards, small movement timbers such as teak might be used, for example. Whereas most structural timbers used in timber frame construction are medium movement softwood timbers, to suit an indoor environment that will be subject to cycles of heating and cooling. n

Accelerating change in a climate emergency

Gary Newman discusses the complex challenges associated with the net zero carbon agenda across different stakeholders, highlights steps already taken in Wales, and proposes calls for action to the industry which he believes will remain relevant over the next few years.

Can the timber sector rise to the complex challenges of the net zero carbon agenda?

Planting trees and building with wood are two largely uncontroversial measures to help the world stay below 2.0°C of warming, but preferably below 1.5°C as per the 2015 Paris Agreement. The Intergovernmental Panel on Climate Change (IPCC) states that while staying below 1.5°C is technically feasible, it would take “unprecedented transformation of all aspects of society”.1

Looking across wood and construction, this article explores how such transformation can be brought about in reality. It builds upon an article I wrote for this publication in 2020,2 which sought to describe the challenge. I will focus largely on Wales, but the content is also relevant to those involved in the other regions of the UK.

Transformation challenges around the net zero carbon agenda

In our context, some examples of the transformation challenge are:

1. FORESTRY: Creating forests means a change in land use, which in turn means a change in rural employment requiring new training and skills. Furthermore, if we are to grow the timber that we need to decarbonise our built environment, the forest industry will need what could be called a societal ‘licence to operate’ enabling what will mostly be coniferous trees to be grown, managed and cut down at increasing scale. As with food, so with timber – society must re-evaluate the nature of the compromise between land use and the need to meet our resource needs in the context of increasingly unstable international supply chains. Over the past few years, we can see that the words ‘resilience’ and ‘adaptation’ have started to sit alongside the more familiar ‘sustainability’ and ‘decarbonisation’.

2. CONSTRUCTION: building more widely with timber in an industry that’s become comfortable with steel, concrete, and plastic requires a much deeper understanding of wood properties than is typically found across the construction professions and trades. For example, all the UK structural engineers with expertise in timber could probably gather in a small house party. Carpenters are not taught about forestry or wood science. Planning authorities still largely >>

encourage estates with parking for two cars, with layouts, typologies and aesthetics based on the past rather than on the needs of the future. More recently, in the post-Grenfell market, UK insurers, lenders and warranty providers view timber construction as higher risk, creating a significant barrier to developers. However, rapid transformation implies innovation and change. This is in direct tension with conservative industries that view change as risk.

3. MANUFACTURING: Sandwiched in between the trees and construction we have manufacturing. By comparison with forestry and construction, this is a more pragmatic part of the system less bound up in tradition. However, in the UK we have almost no engineered wood product manufacturing and very little use of home-grown sawnwood in the construction sector. UK governments have not considered timber an industrial material worthy of policy interventions. The current Westminster policy document, The England Trees Action Plan 2021-2024, astonishingly makes only a passing and relatively superficial reference to the role of timber as an essential raw material. Maybe this is because Britain has viewed the world as its hypermarket, with wood products that can be picked off the shelf as required. The ecological, climatic and political instabilities that have started to appear make this behaviour very unsafe, and in a world predicted to stabilise at a resource-hungry global population of between 10 and 11 billion before the end of this century, this approach will increasingly have a moral dimension.

System change for climate mitigation

Effectively, even the seemingly relatively small task of developing UK forest industries involves buy-in from almost

all aspects of our society. As the holder of two climate change mitigation solutions in trees (carbon removal) and timber construction (carbon storage), the sector will need to adjust to being in the spotlight and increasingly embrace both the responsibility as well as the opportunity. Working in sectoral silos or in market isolation no longer seems appropriate.

We should say at this point that Woodknowledge Wales is a system change membership alliance. We are a for public good community benefit society with a vision for Wales as a high value low carbon forest nation. Our purpose is to catalyse and accelerate change in a way that ethically addresses the environmental challenges and at the same time improves the lives of people in Wales.

In Wales, policies are starting to emerge from the climate change ministry (which has broad responsibilities for the natural and built environments) that >>

show the Government understands the critically important role that forestry and timber can play. For example:

• A timber industrial strategy is under development which focuses on the critical function of trees to provide a resource for society as well as being an environmental good.

• Social housing policy now encourages the use of timber and the measurement and reduction of embodied carbon.

• Encouraged by Welsh Government, 17 Welsh local authorities and Welsh housing associations are currently procuring a delivery partner to design a standardised net zero carbon social house to be manufactured by a geographically diffuse Welsh timber manufacturing sector and rolled out across Wales.

• The Welsh Government is proactively encouraging strategically important timber manufacturing industries to develop and locate in Wales, to produce such products as woodfibre insulation, glulam and timber windows.

• A target to plant 43,000 hectares of new forest by 2030 and 180,000 hectares by 2050 (more than a 50% increase in Welsh forest area from 14% of land area to 21%) enabled by a substantial increase in grant support and a focus upon overcoming the regulatory hurdles.

Calls for action to accelerate incremental change

Taken within the context of Wales being a grazing nation and a steel nation, this is certainly a radical set of policies that we enthusiastically support and are helping to implement. But policies alone are insufficient to lead to rapid and transformative change. Policies don’t plant trees, process wood or build houses. People do. We believe that things can move fastest when organisations involved in delivery work together to solve problems in the spirit of collaboration and shared interest.

Woodknowledge Wales’ role is to work with its cross-sectoral membership alliance of housing providers, architects, manufacturers, sawmillers and forest managers to help articulate the issues and co-create solutions at the coalface of application. This is a bottom-up approach to help organisations respond effectively to the ambitions of current Welsh policy. This means we focus on the practical barriers that our members and networks face – whether that’s in building with wood, manufacturing timber products, or growing the kinds of trees that industry needs.

There are rarely simple answers, but there are lots of good examples of what works that we can amplify through workshops, events and the publication of guidance. For us, the transformation needed is best delivered through the articulation of what needs to be done and then delivered by accelerating incremental change. n

Growing trees

In terms of afforestation, farmers understand grazing, but trees are relatively new-fangled. How can we achieve such ambitious tree planting targets when many Welsh landowners see trees as either a threat to a way of life or a sign of failure? Furthermore, the short-term tenancy arrangement of many farmers means that they are effectively excluded from the ability to make long-term strategic decisions to change the use of land.

Find out more about how we are working with farmers in our series of guidance notes and videos that provide practical information for farmers and other landowners interested in investing in forestry.

Growing homes

In terms of housing, we are beginning to overcome the lack of knowledge about how to use timber well and are increasingly using home-grown timber for the structural frame.

Find out how we are working with housing providers and our key findings around how a timber supply chain based on local forestry products can support the delivery of low carbon social housing in Wales.

Growing manufacture

In terms of manufacturing, we’re co-developing timber systems for housing that can achieve zero whole life carbon impact and we’re looking at alternative procurement options to facilitate their delivery.

Unlocking the potential of modern construction

Matt Holman considers how to help unlock the potential of modern methods of construction with inputs from a series of panel discussions, held over the past six months by Gardiner & Theobald, with experts from across the supply chain.

The term ‘modern methods of construction (MMC)’ has become synonymous with innovative ways of building – utilising a variety of processes and systems, often involving digital technology to maximise productivity and efficiency. Although popularity is growing, there is uncertainty from some stakeholders about the future of these innovations and whether or not the current supply chain challenges can be overcome

Over the last six months, Gardiner & Theobald (G&T) convened a series of panel discussions with experts from across the supply chain to help unlock the potential of MMC. Oliver Booth and I hosted these discussions which focused on key considerations for off-site manufacture, the impact using MMC can have on procurement and the challenges that can be faced on-site. Each stage of the project life cycle was examined by an expert panel, breaking down the myths and dispelling many preconceptions.

Insights drawn from these conversations included the need for greater engagement with the supply chain to ensure design and delivery partners are aligned from the outset. We discovered the importance of understanding the manufacturing process of any chosen MMC solution when embarking on a new development, to help the project team respond to questions from independent consultants such as a building control officer, and the insurance industry. We also highlighted key considerations for mitigating against on-site challenges and how to ensure maximum value when Designing for Manufacture and Assembly (DfMA), accounting for the impact that taking an alternative procurement route can have on the programme of a development.

In the following discussion, I outline the takeaways from these sessions.

Designing for off-site manufacture

In the first discussion of the series, the live audience voted on what they perceived to be the biggest challenges that might be faced when implementing MMC within construction projects (Figure 1)

Supply chain resilience was thought to be the biggest challenge, closely followed by change management and the perceived lack of flexibility when implementing the solutions on-site. In the discussion that followed, the panel advised that designing for off-site manufacture at the outset of your project and engaging with your chosen manufacturer early will help to mitigate against risks that may be faced later down the line in the project life cycle.

During this session education and upskilling the current workforce were noted as key challenges we would need to overcome to encourage greater uptake of MMC solutions. However, the panel suggested that these challenges also >>

“We discovered the importance of understanding the manufacturing process of any chosen MMC solution when embarking on a new development.”

present a great opportunity for future growth within the sector – changing the focus from the need for a skilled on-site workforce to a need for the education of those engineering the products in the factory.

Planning, procurement and the role of government

The central part of the series looked at planning, procurement and the opportunities for considering alternative approaches, as well as the role the UK Government has to play in driving the uptake of MMC.

Key considerations included early supply chain engagement as a top priority for ensuring that developments benefit from the programme opportunities and efficiencies available when using MMC. Securing a manufacturing partner early was once again mentioned, and that early engagement with a building control body can also benefit the overall project programme and help ensure successful delivery.

This was a continuous theme throughout all three sessions – so much so that by halfway through the series, 83% of the webinar audience agreed that they would be open to considering alternative procurement routes for future projects to ensure maximum value and support earlier engagement of the supply chain (Figure 2)

Insurance, onsite challenges and buildability

In the concluding part of our series, we turned our thoughts to the insurance industry, key on-site challenges and what can be done to mitigate against these challenges. We also asked experts from the supply chain, and developers who have implemented MMC solutions successfully, for their advice.

Insurance is often a difficult part of any project that uses new or innovative approaches and, as such, was highlighted as a key topic from the outset. Experts from the supply chain and insurance sector shared experiences of obtaining insurance on recent MMC projects and concluded overall that challenges were often the result of a gap in education. A key lesson from the process was to ensure early engagement with insurance providers, bringing the consultants along on the journey from the factory to the construction site.

When asked what role government could play in supporting the uptake of MMC (Figure 3), 41% of the audience voted for changes to regulation and legislation, followed by the application of planning conditions (19%) and increased subsidies alongside tax reliefs (14%). This shows the desire for greater engagement from government with these new building approaches and that new legislation and guidance would be welcomed by the built environment.

80% of the audience thought MMC solutions would be easier to use on-site than traditional construction methods.

Although our discussions suggest that the biggest challenge faced on-site is perceived as the interface between traditional elements of a development and MMC solutions, we discussed with the experts how best to mitigate against this. >>

“Key considerations included early supply chain engagement as a top priority for ensuring that developments benefit from the programme opportunities and efficiencies available.”

Involving the supply chain throughout the project life cycle will help to ensure all stakeholders are aligned on the plan for delivery and assembly from the outset, avoiding potential problems later downstream. This was noted as being especially important when using MMC, as there is a smaller margin for error on-site, when components are being manufactured off-site.

In summary

The conclusion at the end of our three-part series was that early engagement with the supply chain and wider project team was vital for success when using MMC solutions. Early engagement helps align both the design and delivery as well as maximising efficiencies within the programme and this approach can be felt at every stage throughout the project life cycle.

Education, to ensure consultants and stakeholders are taken on the journey from the outset of the development, can also help mitigate against the key challenges in the factory and on-site. It can also help to avoid downstream manufacturing issues, such as the identification of interface discrepancies or assembly challenges before they have left the factory floor. If choosing an MMC solution, considering an alternative procurement approach to help support early engagement could help mitigate the risk of later-stage programme challenges.

The full details and key findings from these discussions, including any outcomes, will be summarised in a white paper due for release later this year.

How to avoid structural timber design failure

Watch it! Timber does not behave in the same way as inorganic materials such as steel and concrete. Here, Ishan Abeysekera highlights aspects of timber design that engineers used to designing in more traditional materials should be aware of.

Timber structures Engineered timber

Timber: the material

Timber is a natural material harvested from trees. The microstructure of timber consists of tubes that transport nutrients and water through the tree, so it is helpful to think of timber as a bundle of straws. This structure makes timber much stronger parallel to the grain, for forces acting in the direction of straws, than perpendicular to the grain. Imagine trying to squash a bunch of tightly packed straws top down (axial loading), compared with how easy it would be to put a hand around the bundle and squeeze, bending them through their middles.

Since trees need branches, timber incorporates knots. Compared with ‘perfect’ straight-grained, knot-free timber, the tension strength of structural timber is more affected by knots in an off-axis grain direction than the compression strength. During axial (top-down) loading, a knot will be at the point of maximum stress wherever it is in the section. So, while the presence of a knot will always reduce axial capacity, its effect on the bending capacity will depend on where in the section it is. Knots at the edges of a timber beam will reduce bending strength significantly, while a knot at its centre will have little effect.

Duration of load also affects timber strength. At higher loads, creep behaviour of timber will not be stable (logarithmic with time) and will instead be unstable (exponential with time), creeping towards failure. So, engineers must apply load duration factors to keep the applied stress in real, long-term construction projects below documented strength levels that are measured in relatively short-term tests. When assessing design strength, the load case with the shortest load duration will govern the load duration factor for any given load combination.

Double-check sections and elements

Curved and tapered timber sections are readily available from several manufacturers. With curved elements, in addition to standard checks, engineers should carry out additional checks on tension perpendicular to grain, locked-in stresses due to glueing of curved laminates and non-linear section stress.

Tapered sections also require additional checks of shear forces and tension perpendicular to grain. >>

“Since trees need branches, timber incorporates knots. This makes timber stronger in bending than in compression or tension.”

Timber structures Engineered timber

Calculate connection strength at concept

Connections are generally the weak points of timber structures. There is limited space to fit in screws, and slots for steel flitch plates can weaken the member. Design engineers who are used to adding reinforcement into a concrete connection, or welding on extra steel to make a connection work later in the design process, must learn to account for the nature of timber in an earlier design phase. If not, they risk having to increase member sizes to carry the connection forces.

Timber connections should be checked very early in the design and span to depth tables should be used with caution. As a rough rule, at concept design stage, beams should be sized to assume that connections have only 60% of the strength of the full timber cross-section.

Understand slip at timber connections

Timber connections are relatively flexible due to slip on the bolts, screws etc. This is due to oversizing of the hole and local crushing of the timber.

The stiffness of timber connections is highly variable and impossible to predict with any accuracy. Figure 1 provides just one example of just how variable a single lateral dowel type connection can be. So, the values in design codes should be used with extreme caution.

This has several implications:

• Connections significantly increase the deflection of trusses and portals – the increase is most easily calculated by hand using a virtual work method.

• When working with cross laminated timber (CLT) panels, connection stiffness dominates the flexibility of shear walls because the panels themselves are very stiff compared to the connections. Concrete cores make more sense for taller buildings.

• The uncertainty over connection stiffness means that, in indeterminate systems, it can be difficult to determine which path the loads will actually follow.

Minimise moment connections

Joints that transfer bending moment forces between a column and beam, or two or more beams, are known as moment connections. While not impossible, timber column to timber beam moment connections are expensive, difficult to achieve and have relatively low stiffness. Where possible it is often easier to avoid using this type of joint. Where two or more members cross in the same plane, moment connections are extremely difficult to achieve without a complex steel node. Most timber grillages – where one or more tiers of beams are superimposed at right angles to each other to disperse load over an extensive area – are in fact built as one-way spanning structures with short infill pieces in the secondary direction.

Avoid glueing on site

Reliable glueing of timber requires stringent conditions of temperature, moisture content, pressure and cleanliness. This is practically impossible to achieve under site conditions. There is also no non-destructive testing (NDT) that can be undertaken to confirm whether the glueing is adequate. Therefore, structures which rely on glueing on site should be avoided. In addition, even glueing in the factory should only be carried out by experienced fabricators. Where glueing of elements is carried out in the factory the engineer should check whether the manufacturer has adequate quality control measures in place.

Consider the cost of connections

In contrast to steel, where minimising the weight of steel will benefit the bottom line, an engineer must find alternative solutions to balance the influence of connections on the budget within the timber structural design. For example, >>

a truss – which will by definition have connections at nodes – will be materially the most efficient way to span a space, but it may well be cheaper to use a simply supported single spanning glulam beam. This solution will use more timber but has fewer connections.

Be cautious of indeterminate structures

Indeterminate structures with multiple possible load paths such as a propped cantilever beam, for example, make internal force calculation complex. This type of timber structure has uncertain relative stiffness of load paths due to the high flexibility, and variation within that flexibility, of its timber connections.

Timber elements and connections generally fail in a brittle way. Hence governing failure modes of timber structures may be brittle, and the lower bound theory of plasticity will not hold. This means that if a load path of an indeterminate timber structure with multiple load paths becomes overloaded, the load may not successfully redistribute to alternative load paths even if they have the capacity to withstand that additional load. In such a case, internal forces will not remain in equilibrium with the applied load, resulting in structural collapse.

Engineers need to be much more cautious about design than they would be with more ductile and forgiving materials. The simplest solution is to design timber structures with determinate load paths. Where this is not possible, the sensitivity of load distribution to variability of stiffnesses of different load paths should be tested, despite additional costs.

Dynamics governs floor depth

Because timber is lightweight, it is susceptible to higher accelerations and so floor depth can be governed by dynamics. So, it is important to either carry out a dynamic analysis early in the design process or inform the client that dynamics should be checked later and that results may affect the design. Engineers should note that modelling the entire floor plate is significantly beneficial when compared with modelling a few bays, as it will accurately capture the positive contribution of the larger mass of global modes.

Resistance to disproportionate collapse

Since timber is a brittle material, it does not have the ductility required for catenary action. Therefore, where local regulations require resistance to disproportionate collapse, tying is not a viable approach and element removal should be used instead.

It should be noted that element removal as means of achieving disproportionate collapse requirements is much more viable for timber than for more traditional materials because:

• Timber member design is governed by serviceability limit state (SLS) as opposed ultimate limit state (ULS) requirements. This leads to spare capacity at ULS, provided connections are also designed for the accidental load case.

• When compared with steel and concrete structures, the self-weight of timber is a smaller proportion of the total load, so the percentage reduction of total load for the accidental disproportionate loading case is much higher for timber structures. >>

Carefully model CLT with finite element analysis

A CLT panel can be modelled as 2D shell elements when applying finite element (FE) analysis. The designer should bear in mind the following:

• CLT floor systems are generally one-way spanning since half-lap joints along the long edges parallel to the main direction of span can generally only take in-plane forces, not out-of-plane bending and related shear.

• While most software allows for orthotropy to be modelled –different E and G values in different directions – it does not accurately model the stress distribution within the section due to the composite nature of CLT. Hence forces and moments should be obtained from the model, rather than stresses. Internal stresses in the CLT should then be calculated from these forces and moments using the methods provided in literature.

• When modelling CLT in software it is important to ensure that stiffness is modelled correctly for the directions being considered. The equivalent E value of CLT required to model the axial in-plane stiffness is different to the equivalent E value of CLT required to model the out-of-plane behaviour in the same direction.

Combining timber with steel: differential thermal expansion

Timber has a low coefficient of thermal expansion and is also a good insulator, therefore engineers can generally ignore thermal expansion. However, where timber is coupled with steel, it is important to consider the effects of the different thermal behaviour of the two materials. Contraction and expansion of the steel can lead to additional forces in both the timber and steel elements, as well in the connections.

In a bow truss, thermal expansion of the steel tie could lead to significantly increased bending stresses (and deflections) in the timber.

Differential vertical shortening

Where steel or concrete is used for the lateral stability system, but timber for the columns, there will be a differential vertical deflection between the timber structure and the core.

The analysis of this differential deflection, especially where the core is made from concrete, requires particular care. Timber and concrete have different stiffnesses, different creep moduli and different rates of creep. A staged construction analysis accounting for the different properties of timber and concrete will give the most accurate and economic results.

Since differential vertical shortening will generally give rise to SLS issues it is sensible to place the vertical timber columns

as far away from the core as possible. This will reduce the slope between the timber vertical structure and the concrete/ steel vertical structure.

Consult with specialists for acoustics, fire and durability

The acoustics, fire safety and durability of a timber structure are all impacted by the natural behaviours of the material and design engineers are advised to work with specialists to ensure these parameters are correctly managed.

Early consultation with an acoustic engineer is advisable when designing timber floors as they may need additional finishes for acoustic purposes due to their naturally low mass. The amount of timber exposed to fire is critical to safety, so consultation with a fire engineer when designing and selecting timber elements is advisable.

It is very important that timber is kept dry during its service life and during construction. If the moisture content of timber increases above 20% for an extended period, there will be a risk of fungal decay. A moisture control plan should be produced by the contractor to show their methodology for tracking and controlling the moisture content in the timber during construction, as well as mitigation measures if the moisture content starts to rise towards 20%. Waterproofing, ventilation and leak detection mechanisms should be included in the building design, to include adequate protection of engineered wood panels, timber end-grain, connections and ground contact timbers.

The durability of embedded steel connections should also be considered as they cannot be maintained. An example is steel flitch plates in a pool, coastal or external environment which are still exposed to the air but cannot be inspected or repainted.

Designing with timber

When managed correctly, timber is a remarkable material to work with. Design engineers willing to take the time to learn about this material, apply forethought during the early phases of the design concept, and work with experts for those areas needing specialist understanding will be well placed to deliver beautiful, durable and long standing timber structures. n

Designing durable timber structures

The effects of moisture on timber can be challenging. Andrew Lawrence discusses how wood differs from steel and concrete and, therefore, needs a different approach to design.

Timber structures Moisture

The effects of water can affect the strength of the wood. It can also cause it to shrink and swell, which then affects the detailing of connections. Finally, but most importantly, moisture can cause wood to decay. This article focuses on ways of preventing decay through design.

Along with BM TRADA’s timber inspection team, I have, throughout my career, witnessed degradation of timber in buildings and other structures, but I really should emphasise that this is not a problem with the material itself, rather a lack of understanding about its properties. This is because many of those switching to using timber in construction are more familiar with design detailing intended for concrete or steel. So, the problem is more to do with a lack of understanding about timber as a construction material than with the material itself.

Understanding how to avoid timber decay

My own personal understanding of how to avoid timber decay has come from the projects I’ve undertaken.

For example, Durham University wanted to convert an old barn into a student bar and student computer room. It was my job, as a very young engineer, to decide what condition that barn roof was in. It was a trussed timber roof and, from what I could see on the surface, it looked structurally sound. However, the ends of the roof trusses were hidden within the brickwork, so I thought it best to check what condition they were in. Having exposed the first timber, I discovered it was so rotten that I was able to push my entire hand right through it. So, on my very first timber project, I discovered a key fact. If exposed to the air, timber is ventilated and able to dry. However, as soon as you enclose it in other materials such as brick, if it becomes wet it will stay wet and be likely to rot. >>

The good news is that wood needs water to rot. So, all we must do is keep it dry and it can last for centuries.

Historical lessons in the natural durability of timber

This is demonstrated perfectly by Greensted Church, in Essex. Believed to be the oldest timber building in Europe, the walls of the nave are built using a traditional Saxon method from large split oak tree trunks, protected from rain by deep eaves. Built just before the Norman invasion, this building has survived nearly a thousand years.

So, if designed using the correct detailing, timber is an incredibly durable material and correct detailing means keeping it dry –by lifting it up off the ground, overhanging the roof to shelter the walls, and selecting the timber for its natural durability.

The designers of Greensted Church knew that oak is full of tannic acid. If you slice through an oak log, the heartwood in the middle of the log is darker because the cells are full of tannins and other extractives. Natural waste products from photosynthesis, these tannins are also toxic to fungus, making this timber naturally resistant to rot. However, while tannin is an excellent natural preservative, it will eventually wash out.

International lessons in timber preservation

To better understand how to protect timber from decay using good design, I was lucky to receive an award from The Institution of Structural Engineers (IStructE) to travel to see how timber bridges had been built in the USA, Norway and Germany.

I visited many traditional timber bridges, including the famed covered bridge in Iowa that is highly recognisable from the film The Bridges of Madison County. I came to realise that, like many bridges across North America and Central Europe, this iconic bridge is covered not to keep besotted tourists dry, but to keep that timber structure inside dry and prevent it from rotting. The wooden cladding probably leaks, of course, but the entire structure is so well ventilated it can survive a bit of water coming through.

structures

A very similar principle is used in timber framed buildings, where tiles may occasionally slip and allow a small amount of water in, but as long as the roof space remains well ventilated all should be well. This is a point that is often forgotten when loft rooms are built within a roof space.

Treating softwood timbers for increased durability

During the 19th Century, people were looking for ways to build that no longer relied upon less-available, naturally durable timbers or expensive roofs. Instead, they sought ways to make plentiful softwoods from the Baltic regions more durable by using chemical protection.

In London, John Howard Kyan discovered a process for preserving wood which involved dipping logs in a solution of mercury (II) chloride (mercury bichloride). This ‘kyanising’ process was, of course, highly toxic but extremely effective. Produced by mixing hydrochloric acid with a hot, concentrated mercury (I) nitrate, the solution was a common over-the-counter disinfectant at the time, used to treat everything from measles to ulcers.

Around the same time, another treatment was developed from a common antiseptic cream derived from the distillation of various tars and pyrolysis of organic matter. Known as the ‘preserver of flesh’, before being recognised as carcinogenic, the mixture was used for a variety of applications from stabilising smoked meat, to burning off malignant skin tissue and preventing necrosis in dentistry. Pronounced κρέας (kreas) ‘meat’, and σωτήρ (sōtēr) ‘preserver’ in Greek, this treatment later become known as creosote. It is still used to help protect timber bridges in North America. Here in the UK, we use it to protect ground contact external timbers such as telegraph poles. Creosote can bring the service life of these timber structures to around 50 years or so.

In Norway, the road administration wanted to achieve 100 years of service life for their bridges. So, they developed a combination of four complementary measures.

1. First, before the individual planks were glued together they were treated with a careful combination of copper, chrome and arsenic in a pressure vessel. Although this is now restricted, it was a common preservative at the time. However, like all pressure treatments it only penetrates the sapwood even of permeable timbers, and therefore it needs to be combined with other measures.

2. Secondly, once the planks had been glued together into finished glulam, they were pressure treated with creosote. This gave them a water-resistant shell that prevented the wood from getting wet or drying inconsistently and fissuring.

3. Thirdly, copper caps were used to protect flat surfaces from standing water.

4. Lastly, they were very careful with connection details which would include steel plates in a slot that was open at the bottom allowing water to drain away quickly.

This four-pronged approach is relatively successful but is challenged in the 21st Century because the creosote is not chemically fixed into the wood. This means it will slowly leach into the environment, impacting the health of humans, wildlife and the biosphere. The use of copper chrome arsenic is also now heavily restricted, partly because of the challenges of disposal.

Softwood timber protection by design

Germany was the first country to move away from the use of wood preservatives. They came up with a simple twist on traditional covered bridges, which was to use the deck as an overhanging roof to keep the timber dry. Using this approach, they used completely untreated softwood glulam as an underbridge support structure. However, an issue arose with this design when water leaked through the joints of the deck. This could have led to serious structural damage within a matter of months if the leak had not been repaired. But this was a very useful learning experience.

A single line of defence is rarely enough.

Later German bridge design uses what we call a passive leak detection system, for example a pre-cast concrete deck with gutters and drainage pipes that catch and divert the water coming through the gaps between the planks. The system lets the bridge maintenance team know when there’s a leak and where it is, allowing them to quickly resolve and repair the problem >>

Figure 4: Aluminium flashing with ventilation gaps. Photo: © Andrew Lawrence

Today, bridge design in Germany still applies these standard details for waterproofing. In the UK, a similar approach using aluminium flashing with ventilation gaps to create a double line of defence against water damage to the timber connections was used for the wooden roof over the new Crossrail station at Canary Wharf. This incredible structure was designed with holes to allow trees to grow through it, potentially exposing the timbers to the rain. These design details ensure the timber frame has been built to last.

Applying lessons in timber bridge protection to timber frame buildings

Now let’s consider a more ordinary, flat-roofed building made from cross-laminated timber (CLT). How can we ensure the wood keeps dry?

The current standard in the UK is to approach this in a similar way to a concrete roof and to use a waterproofing membrane laid to falls (Figure 5a). But lessons from projects across the industry suggests that a better solution is needed to overcome the risk that poor workmanship or deterioration of the membrane leads to water sitting on the surface of the CLT (Figure 5b).

Now, CLT has many gluelines which are very good at preventing water from seeping through it, so any water penetrating the membrane will sit on top and the timber might stay wet for months, eventually starting to rot.

So, let’s introduce a second line of defence! By simply introducing a ventilated cavity above the wood, we can ensure that any standing water will quickly evaporate away (Figure 5c). However, even this system is limited against large leaks. So, by adding drainage holes (Figure 5d) or a drainage spout, we not only allow water to escape but provide ourselves with a visible passive leak detection system. By laying our CLT roof with a slight fall towards those drainage holes, we have a complete system to remove moisture build-up during construction and waterproof our wood construction over the long term. Of course there are many variations, but the general principle to waterproofing CLT on future projects should be to have two lines of defence and also a warning of leaks.

Designing long lasting, durable timber structures

Timber is an amazing material but, as a natural material, it has different properties from concrete or steel. So, we need to learn how to use it, and how to design with it safely, to create long lasting durable structures.

For non-structural timbers such as cladding or decking, failure will not result in safety issues. In these cases, I believe we can afford to expose the wood to rain, using pressure-treated woods and naturally durable species, employing careful detailing to avoid water traps and maximise service life to as long as 30 or 40 years.

However, if structural timbers fail, there is a potential for structural collapse, injury and even loss of life. We must, therefore, assume from the outset that any timber structure is at risk from moisture and design in completely failsafe waterproofing to ensure the wood never stays wet, so can never rot. By using several tactics, such as membranes, ventilated cavities and drainage, we can both ensure our wood can dry out and detect and repair any leaks when they do occur, keeping our structural timber and those who use our buildings safe. n

How to draft a BSI framework for competence

On 27 July 2022, the PAS 8671:2022 Built environment – Framework for competence of individual Principal Designers – Specification1 was published by BSI. Here, we interview Matt Thompson, the technical writer responsible for this document.

The PAS 8671:2022 development story

Last year, a team of experts sat down to write the new PAS 8671 standard. The team consisted of multiple experts from across relevant fields.

What is PAS 8671?

PAS 8671 is one of three PASs (Publicly Available Specifications) published by BSI. It and PAS 8672 focus on competency frameworks for Principal Designer and Principal Contractor duty holders, as introduced under the Building Safety Act (BSA).2 The PAS series is sponsored by the UK Government’s Department for Levelling Up, Housing and Communities (DLUHC). The final framework has been influenced by secondary legislation further to the Building Safety Act arising from Dame Judith Hackitt’s review following the Grenfell fire.

As outlined on the BSI website, PAS 8671 “...specifies competence thresholds that individuals are expected to meet when delivering or managing the duty holder functions of the Principal Designer, and additional competencies for working on higher-risk buildings (HRBs).”1

“A key legal requirement is that the Principal Designer (PD) must plan, manage and monitor design work, and co-operate, co-ordinate and communicate to ensure the design work, if built, complies with building regulations,” said Andrew Moore, Senior Technical Consultant and qualified architect from the HSE. “To do this, it is important that the PD is part of the design team and not a third party without any influence over design decisions.”

“The PD should be able to co-ordinate the design team. It may help the PD to keep a record of designers and their responsibilities across a project,” Moore continued. “A PD is not expected to be an expert in every design specialism, but they are expected to know enough about the Building Regulations to assess whether a building design will comply with all relevant regulations.”

How is the framework intended to work?

According to Thompson, how the PD framework works was a significant topic of debate during the process of writing. Even the experts had differing perceptions of its intentions. There was a lot to resolve and explain. One particular contention was the idea that ‘if you follow this you could get certification’ – but that’s overly simplistic and not how the specification is intended to function.

Moore said, “PAS recognises that competence can be achieved and acquired in lots of different ways. The document does not seek to set out these multiple potential pathways, but instead highlights the key competence criteria. It is anticipated that professional bodies, trade associations and training providers will use the PAS standard to develop syllabuses, and certification bodies can develop assessment criteria.”

Thompson reported that draft secondary legislation (on which the PAS is based) has been removed from the DLUHC website pending further consultation. Current schedules predict secondary legislation to come into force in 2023. When published, PAS 8671 was aligned with draft legislation but, if wording in secondary legislation subsequently changes, tweaks may be needed later. BSI maintenance timescales currently schedule updates two years following initial publication, although that too could change.

How did the draft evolve and what were the development challenges?

A large collaborative body of work on competence has emerged from the Hackitt report, which informs the PAS series, and the published version of PAS 8671 evolved through two consultation versions.

The team’s starting point was not ‘what are the techniques that are known to improve compliance on a building project?’ but rather ‘what must PDs do to meet legislation governing their duty holder role?’. The first version was reviewed by the PAS 8671 Steering Group. It was a very detailed, aspirational first pass that was written without proper sight of draft secondary legislation. >>

The second public consultation version simplified the first but was still overreaching. It received hundreds of comments in the feedback process that were each considered and discussed at length. It was clear that it didn’t clearly enough distinguish the PD role in the draft regulations from the duty holder role with the same name under the CDM Regulations. Also, it became apparent that the activities logically inferred from the draft regulations went too far and could create unwarranted liabilities for persons in the PD role.

The third, and currently final, version distilled the document down to just the minimum thresholds inferred from the draft legislation, and clarified the distinction between the two different PD duty holder roles.

The minimum thresholds are defined using Bloom’s Taxonomy. This is a hierarchical classification of different levels of thinking commonly applied in describing educational attainment levels.

How does PAS 8671 specify the PD role?

The official status of this standard is that it sets minimum thresholds of competence needed for individuals in the PD role. It references the ‘BSI Flex 8670’ part of the overall BSI Flex framework, which supports wider industry reform and should be adopted by anyone with a direct influence on safety in and around buildings. Flex is a normative reference in PAS 8671, so it assumes its content. A normative reference is a document that is indispensable for the application of the standard, so anyone reading PAS 8671 will also need to understand this foundational reference.

PAS 8671 is a framework for frameworks. It sits above established competence frameworks or those in the process of being developed around the roles of designer and

architect, for example. This is because a ‘designer’ can be almost anyone – the designation has a very fluid definition, including not just architects but almost anyone else in a position to influence the design, including the contractor and, indeed, the client.

PAS 8671 identifies two levels of competence for the PD role under the draft regulations introduced by the BSA which are unlikely to change much, despite the fact that the secondary legislation has not yet been finalised. These are:

• General competence to work as PD on all projects other than higher-risk buildings.

• Additional competence to work as PD on higher-risk buildings.

The PD role under the Building Safety Act is about achieving ‘design work compliance’ (a term defined in the PAS). Some might be surprised to discover that the main focus is therefore not health and safety per se but compliance with ‘relevant requirements’, which includes Building Regulations. In contrast, the PD role under CDM regulations is about managing risks to health and safety during a project. While it seems likely that most clients will want to appoint the same organisation to carry out both duty holder roles, the two are different and could in theory be carried out by two separate organisations.

“The development of a PAS is a robust process,” said Moore. “At HSE we are used to ‘holding the pen’ when developing information for industry, however rightly. HSE’s views carried no more weight than any other stakeholder on the steering group. This challenge is, however, exactly what HSE is looking for, with industry representatives (through the BSI) taking the lead in establishing standards, rather than waiting for things to be mandated by the regulator.” >>

Clients will have to satisfy themselves that people are competent and can satisfy the regulations. The BS Flex 8670 and the three associated PASs help in determining what the competence should be.

How will PAS 8671 affect construction projects and designers?

Clients will need to appoint a BSA PD on almost all construction projects, even very small ones. So, PAS 8671 competences are intended to be inclusive. Their aim is not to contribute to a reduction in competence, but neither will they increase liabilities. This is a difficult line to tread.

The PAS 8671 specifies the thresholds of competence the PD needs to have reached to fulfil the duty holder role and manage its functions. It does not set any prerequisite conditions for serving as a PD, or tell you the learning pathways to get there, or specify what you need to do to ‘prove’ it or to stay competent.

On 17 July 2022, in their ‘Building Safety Act – Structural Safety’ blog, the unnamed authors of ‘Safebuild UK’ noted: “Structural integrity is a huge and complex subject and there are no details about what is considered a hazard resulting in a risk of structural failure in the act […] The Principal Designer, along with any other designer, could be held criminally liable for any structural failure, that results or could have resulted in a ‘major incident’ which is an incident resulting in significant number of deaths, or serious injury to a significant number of people. This raises a number of issues for Principal Designers who tend not to be structural engineers. Relying on your structural engineer does not relieve you of your duties, so where do you start?”

There are also ‘behavioural competencies’ to consider. So, while PDs don’t have to be technically competent in all aspects of a build, they DO need to be competent to a) know when they’re not technically competent enough and b) make good the deficit by bringing on board appropriate consultants.

“I think the new PAS standard will reinforce the importance of the PD role and provide industry with a clear competence framework that individuals can measure themselves against before they seek further training, upskilling if they identify gaps in their skills, knowledge or experience,” said Moore.

Just as designers should only take on the PD role if they are competent, so clients have a duty to satisfy themselves of their PD’s competence. The question is, how might clients do this? On the designer’s say-so, or on the basis of some certification that establishes it? The hope is that PAS 8671 will help certification bodies to set assessment criteria and thus help them to develop robust, preferably third-party accredited, certification schemes that both designers and clients can trust. n

Taking on the hot topic of fire regulation

In a candid interview, Warringtonfire’s technical manager, Peter Barker, and regulatory analyst, Ross Newman, offer expert commentary on recent changes to building regulations and guidance. Breaking down regulatory complexity into key facts, they discuss the legislative changes every responsible construction industry professional must be aware of.

So much has happened within the building and construction sector over the past decade that has resulted in the need for new legislation. New energy requirements for buildings led to changes to Approved Document L for conservation of fuel and power1 and this continues to drive the political agenda as well as how we construct buildings.

Brexit has resulted in the UK adopting much from the European system with the intention of updating it to meet evolving national requirements. But probably the biggest regulatory change has followed on from the tragic Grenfell Tower fire and the resulting construction industry review by Dame Judith Hackitt.2 The UK Government’s role is to now respond to that report and drive changes to the Approved Documents specifically around fire safety and structural safety.

Here, we ask Peter Barker and Ross Newman for their understanding of just some of the upcoming changes relating to the England’s fire regulations.

Q: Who will be most affected by change in fire legislation?

Ross: Some of the major changes are being driven by Approved Document L as a result of increasing the requirement for insulation within buildings. In a relatively new amendment, published in 2021, the requirement for external wall performance, or what is known as a ‘U-value’, has increased. That will result in the need for more insulation or thicker walls to achieve this higher target.

We’ve also had a number of changes to Approved Document B and Regulation 7, which cover materials and workmanship. These amendments have effectively created changes in how timber may be used in construction. Specifically, at height and in relation to what’s now known as a ‘relevant building’ under Regulation 7 clause 43 and residential buildings under Purpose Groups 1 and 2.4

The most recent changes to Approved Document B came into play from 1 December 20224 and relate to the use of >>

He applies his expertise to the development of national and international standards, currently focused on British Standards and non-ISO (International Organization for Standardization) European standards. He supports trade associations and has technical input into testing, technical assessments and certification of construction products, specialising in fire-resisting doorsets. He also authors technical papers and presentations on technical subjects for magazines and journals.

Ross Newman has been involved in the testing and certification industry since 2004, predominantly in the world of fire resistance. He has extensive experience in fire resistance testing and running testing laboratories dealing with the fire resistance of walls, floors, doors, and anything that might penetrate those walls and floors, such as glazing, firestopping, products, pipes, cable services and more. He has been heavily involved in both European and British Standards Committees, again specialising in fire resistance, product testing and certification areas. Now Ross has moved into the role of regulatory analyst and he is more focused on understanding and sharing knowledge around new regulation, legislative change, and how changes in guidelines may affect Warringtonfire and its customers moving forward.

POWER OF

combustible materials at defined heights of 11m and 18m (also known as trigger heights). These changes will impact the use of timber cladding for high-rise residential projects and may also affect buildings constructed using structural timber frame.

Lastly, anything to do with attachments, such as balconies, will likely become areas where timber will no longer be used above specific heights.

Building regulations and associated statutory guidance are currently under technical review and further changes are coming, but we don’t know exactly what those are yet.

Peter: It is worth pointing out that under the Building Safety Act there will be a gateway process introduced, which will be overseen by a newly defined role called the Building Safety Regulator (held under HSE). The Building Safety Regulator will be responsible for signing off the planning, construction and completion stages for those buildings that fall within scope. Gateway 1, which is the planning stage of the Gateway regime, came into force on 1 August 2021 through the introduction of the Town and Country Planning (Development Management Procedure and Section 62A Applications) (England) (Amendment) Order 2021 and requires fire safety matters to be incorporated into the planning stage for higherrisk buildings. Gateway 1 is intended to help ensure that applicants and decision-makers consider planning issues relevant to fire safety at the earliest possible stage in the development process. Gateway 2 will introduce a hard stop on construction, unless the Regulator has approved the application and at Gateway 3, there will be hard stop on occupation until the Regulator has carried out final inspections and issued a Completion Certificate. It is likely therefore that designers and contractors that are building high-rise/high-risk buildings will find it increasingly difficult to follow the current design and build approach.

Q: So, what are the key legislative changes designers, architects and developers should pay heed to?

Ross: I would say a key thing to look out for is that the construction industry should now be using the European classification system for reaction to fire performance following the amendments to Approved Document B.

Previously, there were alternative options, and either the national classification system5,6 or the European classification under BS EN 13501-17 could be used for demonstrating reaction to fire performance. Now, in nearly all cases, Approved Document B points to the European system of classification, whether that is for external cladding materials, internal finishes, raw CLT, or other materials. Evidence needs to be based on the European classification system and will normally require a minimum classification level of B-s3,d2. However, the

classification requirements for certain products, such as those used on external walls, are more stringent where used on buildings in excess of the trigger heights stated in Approved Document B. It is worth noting that timber products, even when treated with specific treatments for reaction to fire performance, are unlikely to achieve a greater than ‘B’ classification.

Peter: I think its worth adding that on the 23rd December 2022 the Department for Levelling Up Housing and Communities (DLUHC) opened a public consultation in England seeking feedback from relevant groups on proposals to remove national classifications from Approved Document B (ADB). Although no decisions have yet been made, DLUHC’s proposals inevitably may be seen as an indication of the future direction of travel with regard to the replacement of the BS standard suite by the European test standards and classification system.

Q: How will these regulatory changes affect a typical residential building site?

Ross: Most of these regulatory amendments relate to buildings of medium height and high rise. But that is not to say that some of these changes do not apply to your typical residential building site. There are reaction to fire requirements for the external surface of materials, such as timber cladding, to meet a certain European classification, specifically when it comes to how close a building is to a boundary.

Previously, if you used certain varnishes or paint materials to finish a timber product, it might have achieved a Class 0 or Class 3 under the national classification. These results are unlikely to be acceptable anymore. You must now be looking at the European classification system to ensure your finishes meet the relevant requirements in Section B2 and Section B4 of Approved Document B.8

Q: Do the regulatory changes affect completed buildings and those currently being built?

Ross: To answer this question it’s best to refer to the second page in the introduction of the June 2022 amendment to Approved Document B,3 as it tells you that, “The current 2019 edition, incorporating the 2022 amendments will continue to apply, where a building notice or an initial notice has been given to, or full plans deposited with, a local authority before the 1 December 2022.” The amendments therefore apply from 1 December 2022, but I would recommend reading the full details of the June 2022 amendments to Approved Document B for the avoidance of doubt.

Peter: I have a question for Ross. Under the Fire Safety Act9 and Building Safety Act10 for existing buildings, are there now extra considerations relating to the risk assessment for high-rise residential buildings? >>

Ross: That’s a very valid question. The Fire Safety Act9 now requires fire risk assessments of high-rise residential buildings to include external wall constructions and common areas including fire doors.

Q: How have the roles and responsibilities for fire and building safety changed in the new legislation?

Ross: There are a number of new roles that have been introduced under the new legislation, with the primary aim of identifying duty holders who will have clear accountability and statutory responsibility for high-rise residential buildings and other buildings identified as high-risk. The following roles have been defined: Accountable Person(s), Principal Designer and Principal Contractor.

Peter: To follow on from Ross, the roles of the Principal Designer and Principal Contractor include similar responsibilities as those defined under the CDM (Construction Design Management) Regulations 2015,11 but as duty holders under the Building Safety Act, will be required to manage building safety risks, with clear lines of responsibility during the design, construction and completion of all buildings. Accountable persons will need to demonstrate that they have effective, proportionate measures in place to manage building safety risks in the higher-risk buildings for which they are responsible and duty holders such as the Accountable Person, Principal Designer and Principal Contractor, who do not meet their obligations may face criminal charges.

I would also like to mention the interaction between the Responsible Person and the Accountable Person, because there are questions as to whether one replaces the other.

It has now been clarified that they could indeed be the same person. However, the legislation doesn’t replace the Responsible Person with an Accountable Person for those buildings that fall within scope.

The Responsible Person is a defined role that’s been in place since the Regulatory Reform (Fire Safety) Order came into force in 2006.12 New regulations will introduce a requirement for an Accountable Person, as explained. Like I said, they could be the same individual, but it’s not an automatic replacement.

Q: What is the most pressing regulatory change a designer or architect must focus on?

Ross: If I was a designer or an architect working in the world of timber construction or using timber materials, then I think my main focus would really be getting to grips with the current building regulation changes and amendments, including those in the Building Safety Act and in Approved Document L and Approved Document B.

I would really make sure that I have clearly understood what these changes may bring about, what that means, how I can use timber materials, or if it might make more sense to use other materials in certain areas. Of course, you would still want to use timber for a number of reasons, not least of which would be its known environmental and sustainability credentials.

Peter: Yes, I agree. You could follow the design and planning process which you’re previously familiar with, but if you don’t get your head around all the regulatory amendments, you could end up with significant delays and costs at the planning and design stages.

Q: What is the most pressing regulatory change a developer or owner must focus on?

Ross: If you’re what’s currently defined as a client or owner who’s going to be the investor in a development, there are a lot of new requirements that you are going to have to take on in terms of responsibility under the Building Safety Act.12 Again, these new amendments will apply to relevant highrise, high-risk buildings. However, if you are involved in this area there will be a lot to understand in terms of making sure the people that you employ are competent to do the jobs that they’re being asked to do and that you are developing buildings that are safe for people to occupy.

Gateway 1 and the new Gateways 2 and 3 that will kick in through the Building Safety Act as discussed earlier are geared towards higher-risk buildings which are currently defined as those at least 18m in height or containing more than seven storeys.13 At the present time it is not known whether this model will be adopted for all types of buildings.

Q: So, in your opinion, what further regulatory changes are to come?

Ross: I think in 2023, 2024 and 2025 we’re really going to start to see the impact of the secondary legislation from the Building Safety Act. This will affect further changes to those already being made to the Approved Documents and Regulation 7.

I would expect the sector to review their design, specification and procurement processes by making sure products are fit for purpose, and a lot more evidence-based with a paper trail to say why that product or system is suitable for a specific application. This will produce an auditable paper trail, which will be necessary for duty holders to meet the requirements of the new regulatory framework. Some of this information will then be passed on to building occupants by the Accountable Person, which aligns with one of the recommendations made by Dame Judith Hackitt, with respect to maintaining the golden thread of information. >>

Peter: Yes. In future, it will be necessary to cope with a lot more information in terms of records and handover documentation. I think there will be a focus on digital information and how that can be sensibly packaged up for each building. This could drive digital innovation and advances in Building Information Modelling (BIM) – a technology that isn’t currently being exploited as much as it might for what it can achieve.

There’s a lot to get your head around, but I do agree that there will have to be a huge cultural shift in the way that the construction industry communicates with clients. The current structure of subcontractors, subcontracting to further subcontractors, and the way information flows through that chain, will need careful review by the large developers to account for the coming changes.

There is certainly an expectation around increased collaboration between interested parties, from designer through principal contractor, to the point of building handover and ongoing operation. Everyone in the construction industry will need to collaborate to ensure that safety is designed into buildings at the outset. This will be a good thing, resulting in a lot more upfront design detailing prior to the construction stage, with everyone clear that the evidence is already in place to support the chosen design. The new gateways are designed to achieve this. The idea is to know what you are going to build, who is going to build it, and how it’s going to be built at each stage, all the way to the point where the building is to be occupied. The final building then actually represents what you planned to build in the first instance.

Q: So, in future the responsibility for building and fire safety will be shared across all parties with a required custodial chain of evidence?

Peter: Yes.

Ross: Yes. A requirement referred to as ‘the golden thread of information’ in the Hackitt report.

While it’s not yet clear what this golden thread of information will need to include, or what form it will take, it is fairly certain it will be a requirement in future… and one which we will very much depend upon.

We might, for example, emulate the auto industry which requires product numbers and processing details that are

recorded and traced through the production line and in service. Such that anyone can check the construction manual and pick out exactly what the product is, when it needs to be taken in for repairs or maintenance, and where they can go to get a relevant replacement part.

This level of traceability will take many years to implement within the world of construction, because it’s a very different sector that requires tens of thousands of components to produce a single building.

Meanwhile, there are still many unanswered questions, and we must continue to work within the complexities of current legislation while we await further regulatory changes and approved government guidance. n

Getting started with fire protection

Important changes in fire legislation affect your responsibilities as duty holder. Peter Barker

and Ross Newman set the scene.

The Regulatory Reform (Fire Safety) Order (RRFSO)1 imposes important duties and responsibilities for the protection of people from fire in all premises other than private homes. The RRFSO takes a broad view of responsibility and some may not realise they have legal responsibilities for fire protection.

In response to the independent review of building regulations and fire safety, and the recommendations made by Dame Judith Hackitt on the future regulatory system for buildings, the UK Government has introduced significant changes to the Building Regulations for both new and existing buildings. The new legislation amends the RRFSO and introduces additional requirements placed upon duty holders as identified by the RRFSO.

Building Safety Act 2022

The Building Safety Act2 (BSA) received Royal Assent on 28 April 2022. The BSA has a broad scope applicable to new and existing buildings and contains provisions that impact on the requirements of the RRFSO.

Fire Safety Act

The Fire Safety Act 20213 (FSA) received Royal Assent on 29 April 2021 and has a narrower scope than the BSA. The FSA clarifies the parts of a premises that apply under the RRFSO with respect to multi-occupancy buildings, such as external walls and flat entrance doors, and has made specific amendments regarding compliance with risk-based guidance that has been considered appropriate by the Secretary of State.

Fire Safety (England) Regulations 2022

The Fire Safety (England) Regulations 20224 (FSR) are mandatory from 23 January 2023 in England, and are made under article 24 of the RRFSO. They apply to residential buildings, with different requirements linked to the height of the building.

Who is this information intended for?

Throughout this article, ‘you’ refers to the primary duty holders, known as ‘responsible persons’ or other duty holders known as ‘5.3/5.4 persons’ after the relevant article in the RRFSO.

Why is fire protection important?

Unfortunately, fire is always a threat and so premises must be protected. Fire protection is a bit like an insurance policy: the costs are irretrievable and the benefits only felt in the event that you suffer a fire, which might never happen. If it does, of course, you will be very glad you did protect yourself: people are much safer, the fire is far less damaging and business returns to normal more quickly.

If you haven’t carried out your legal responsibilities under the RRFSO with due diligence, the consequences of a fire are more likely to be catastrophic. Deaths and severe casualties among friends, colleagues and anyone else who happens to be present at the time are a very real possibility. Added to that are existential threats to your ‘undertaking’ – usually a business – and the probability of prosecution with attendant penalties of fines and jail terms.

So, while having to consider fire risks may not be welcomed amid all the other competing priorities in your life, the consequences of not doing so are so severe that you cannot afford to ignore them. It ceases to be primarily a legal duty and instead is one of common sense. The precautionary principle applies absolutely.

What do you need to know?

The way the RRFSO is framed puts the duty of responsibility for fire safety on ordinary non-specialists like you. This duty can be very onerous; it requires a broad understanding of many specialist technical subjects, all of them a field of expertise by themselves:

• The legal position: including your liabilities under the RRFSO and with your insurers. >>

• The management of fire safety: including training, maintenance of measures, regular inspections, updating emergency plans, checking compliance.

• Fire risk assessment: including knowing how to identify hazards and the best way to deal with them.

• How fires occur and spread: including an understanding of the physics of ignition, the products of fire and the fire resistance of different materials.

• Effects of fire on people and their behaviour: including both physiological and psychological issues.

• Fire prevention: including managerial, behavioural and technical aspects and how they should work together.

• Passive fire protection: including how to optimise engineered solutions that take account of how buildings work.

• Active fire protection: including complexity in understanding how to fight different kinds of fire and the best methods for achieving that.

• Means of escape: including the most effective ways to evacuate people safely from buildings and account for them.

Doing all that is reasonably practicable

Regardless of the RRFSO, you will want to do what is reasonably practicable to ensure the safety of people you are responsible for in the event of fire, while spending budgets wisely. The RRFSO merely makes this law.

The definition of what is reasonably practicable is open to interpretation and in the event of a prosecution you have to prove that you acted with due diligence.

There is a lot to consider, much of it requiring considerable baseline knowledge, experience and expertise – competence. The RRFSO recognises this and will be amended by the BSA to clarify the requirement for using competent persons when making or reviewing a fire risk assessment under article 9 of the RRFSO.

Sometimes, though, even if you yourself are competent, you must still seek help. Indeed article 18 of the RRFSO requires you, with a few exceptions, to appoint competent persons to help you ‘undertake the preventive and protective measures’.

Remember, liability for the fire safety of people in and around your premises remains yours under the RRFSO, even if it is sometimes shared with others.

technologies

For more than 80 years, Arxada’s wood protection business has led the market in the delivery of trusted and innovative technologies. In 2021 we introduced Tanalith® MF and Vacsol® 6118 - metal free and VOC free, BPR authorised wood preservatives.

• Tanalith® MF is suitable for Use Classes 1 to 3, including 3.2 uncoated, out-of-ground contact, such as cladding and decorative landscaping timbers.

• As a clear wood preservative, vibrant built-in colours can be achieved with Tanalith® Lifestyle.

• Vacsol® 6118 is suitable for Use Classes 1, 2 and 3 (coated), so ideal for frame timber and joinery components.

• Tanalith® E is particularly suitable for in ground contact timbers (Use Class 4).

• Tanasote® is a modern oil-based copper wood preservative designed for high performance timbers, such as utility poles and railway sleepers.

Assessing the environmental impact of treated timber

There is a growing focus on how treated timber performs against more carbon-intensive materials, and untreated timber, across its entire life cycle. Dr Steve Uphill demonstrates the application of the Life Cycle Analysis (LCA) ‘ReCiPe’ method to assess treated timbers for data-led decision making.

Wood preservatives are used to enhance the natural durability of certain timber species, helping to provide protection from decay fungi and insect attack so that the timber can be used in commercial applications. Water-based or oil-based wood preservative is industrially applied through an impregnation process so that it bonds with the timber’s fibres, making wood more durable. For example, European homegrown softwoods that play such an integral role in capturing and storing CO2 from the air, such as spruce and pine, have little natural durability. This means that unless treated, they are unsuitable for applications exposed to weathering (rain, moisture), or near ground level and in the ground.

Like any construction material, wood preservatives are continually evolving with specifier and regulatory demands. While the ultimate aim is to provide long-term protection against decay fungi and insects for less durable timber

species, this must be done in a way that minimises any risk to the environment, or human and animal health. With a wide choice of construction materials available in the marketplace, investment in Environmental Product Declarations (EPDs) and Life Cycle Analysis (LCA) provides designers and construction professionals with the information they need to make informed choices on whether treated timber is the best material option.

In this article I will summarise how wood preservatives are regulated and then explore the current landscape of actives used in formulations. With a focus on the use of organic actives, I will look at the applicable end-uses of treated timber in accordance with BS EN 335-1 Durabiltity of wood and wood-based products. Definitions of use classes – General. To evidence how treated timber can compare with other construction materials, I also include a recent Life Cycle Analysis study, which will help illustrate the type of data that is available.

The regulatory landscape governing wood preservatives

The development, production and use of wood preservation products is regulated in the EU under the Biocidal Products Regulation No 528/2012 (BPR).1 This regulation aims to improve the functioning of the biocidal products market in the EU, while ensuring a high level of protection for humans, animals and the environment.

Under the BPR, authorisation of biocidal products is a two-step process. Firstly, all active substances contained in a product have to be approved at EU level, following assessment of hazardous properties and possible risks. In the second step, biocidal products are evaluated before being authorised. >>

The BPR requires data on the possible exposure and toxicity to humans such as reproduction toxicity, carcinogenicity, or endocrine disruption etc, as well as data on environmental impacts such as accumulation in soil or ecological toxicity.

It also introduces formal exclusion and substitution criteria which apply to the evaluation of active substances. When an active substance is approved, it is granted for a defined number of years. The maximum number of years granted before renewal is 10 years.

In the UK and Northern Ireland, following the UK’s withdrawal from the European Union, GB BPR is in place. GB BPR mirrors EU regulations in large sections but is an independent regulation overseen by the UK Health and Safety Executive.

When developing a new wood preservative it is vital that the regulatory status of available active substances is understood. The BPR process requires substantial investment, involving stringent risk assessments, as well as generating extensive data and studies to prove that the wood preservative is effective against wooddestroying fungi and/or insects. The longevity of authorisation of an active substance is key for these efforts to be successful.

The evolution of actives used in wood preservatives

Across Europe there are a number of water-based wood preservatives available, and a handful of oil-based. When specifying treated timber, it is important to understand how the chemistry behind the wood preservative is suited to the timber’s end-use application. The eventual end-use of preservative treated timber is classified into one of five categories(Figure 1). These ‘Use Classes’, defined in BS EN 335-1, are based on the potential threat to the timber from decay or insect attack in its eventual application.2

Treated timber used in Use Classes 1 and 2, where there is less exposure to wetting such as roofing battens and frame timber, is transitioning across Europe to non-metal preservatives that are based on organic actives. These wood preservatives tend to be low-pressure impregnated to provide an envelope of protection around the timber. Some would put the case as to why internal joinery with little risk to wetting needs to be pressure treated. While the level of risk to wetting is low, these are important components to structural integrity and by using treated timber, longevity and durability will be assured. There are products available that are both metal-free and VOC-free. Timber treated with low-pressure water-based wood preservative that uses organic actives can be reused or recycled at end of life (subject to local waste regulations).

For Use Classes 3(c) and 3(u) – coated and uncoated –non-metal-based wood protection technologies are being developed that can be applied through high-pressure impregnation. However, it is worth noting that in Use Class 3(u), where the treated timber is uncoated and above ground level, these new metal-free technologies will provide a lower service life than the more traditional copper-based wood preservatives. An example would be cladding where a metalfree high-pressure wood preservative would provide roughly 15 years’ worth of protection, whereas copper-based wood preservatives would provide between 20 and 25 years.

In the higher-risk Use Class 4 application, where the treated timber will be in contact with ground or water, water-based wood preservatives containing copper are the most fit for purpose. However, not all copper-based wood preservatives utilise the same actives, which means that different formulations will have different overall environmental impacts. To help timber manufacturers provide a cradle-to-grave environmental assessment of their products, wood preservative manufacturers are being asked to invest in Environmental Product Declarations (EPDs) for all of the brands that they produce. >>

“To help designers and construction professionals truly create sustainable buildings, wood protection technologies must continue to look to actives that consume fewer resources, eradicate waste at landfill at end of life, and have minimal impact on the environment.”

Assessing the whole carbon impact of treated timber: a case study

At Arxada we are investing in both EPDs and Life Cycle Analysis (LCA) for our wood protection technologies. Not only is this critical when comparing treated wood with alternative materials, but also helps evaluate untreated vs treated wood. If treated wood provides longevity and durability, and requires minimal maintenance, then this has a positive impact on the whole carbon footprint.

The most recent LCA I have been involved with is that for Tanasote®, a BPR authorised oil-based copper wood preservative that is a modern alternative to traditional creosote treatments. For this project, the LCA ‘ReCiPe’ method was adopted, covering analysis of the following three categories for end use applications such as railway sleepers and utility poles: (i) damage to ecosystem, (ii) damage to human health and (iii) damage to resources (Figure 2). A sensitivity analysis was also completed to assess the influence of agricultural land occupation and terrestrial land transformation as part of the LCA.

The direction of travel for wood preservatives

With VOC-free and metal-free options now available, and with some copper-based preservatives using such small quantities of copper due to being paired with powerful organic co-biocides, the wood protection industry has certainly evolved. However, the industry cannot be complacent and must continue to invest in educating the market on its progress, to help dispel outdated misconceptions about the use of treated timber.

To help designers and construction professionals create truly sustainable buildings, wood protection technologies must continue to look to actives that consume fewer resources, eradicate waste at landfill at end of life, and have minimal impact on the environment. Significant investment in testing these new formulations will be key to success, demonstrating how the protection technologies perform in the real world n

GIVE NEW WOOD AN AGED LOOK!!

Rubio WoodCream is a water-based cream, which makes wood water repellent after treatment. This results in a long-lasting pearl effect. Due to the cream structure, it is easy to apply, especially on vertical wood.

Dispelling decking and cladding misconceptions

Janet Sycamore discusses how understanding and being able to specify the differences between key components such as joists, batten types, and corrosion-resistant fasteners will help keep your decking and cladding looking beautiful for longer.

As a technical advisory service, the TDCA receives enquiries daily. But too often we get asked the same questions that are fundamental to both timber decking and cladding installation – you’ll read about these later. Be assured, we’re working hard to address them by providing free resources and on-hand guidance.

So, what’s our reason for doing this? As a timber trade body, our objective is to promote best practice and to encourage the optimum use of a construction material that is both sustainable and beautiful.

We’re sure you’ll agree, timber is a miraculous material. Tiny saplings fed by sunlight and rain, are nurtured, managed and eventually turned into serviceable products to be used in all manner of applications. Trees are planted, felled, seasoned, de-barked and sawn – that’s just the beginning – the best wood is selected, graded and precision machined, it may be impregnated with a wood preservative to enhance its service life. Such components which have had all this time and effort invested in them are then passed to the purchaser, the product’s new owner. At this point it’s out of the manufacturer’s control and here’s where the problems can arise.

When is a decking joist not a decking joist?

A deck board is distinguishable and easy to identify; a nicely planed surface with pencil rounded corners and smooth, grooved or ribbed profiles. As long as it’s sourced from a reputable supplier, you know that this component is designed for use as an external decked surface supported off the ground. In a standard that groups all components into end-use classes, this is described as a Use Class 3. It will either be made from a naturally durable species of timber, or will have been preservative pressure treated or modified to achieve the level of durability required.

However, ‘joists’ pose a particular problem. Exterior deck joists and interior floor joists look alike: one can easily be mistaken for the other. Is this a problem? Resolutely ‘yes’ and here’s the first misconception: internal floor joists are categorised as Use Class 2 (interior, above the ground, occasionally wet) while deck joists are assigned to Use Class 4 (exterior, exterior structural support and potentially close to the ground and frequently wet). Deck joists must be more durable than floor joists to withstand the rigours of the outdoors where there’s a greater risk of decay. So, pressure-treated softwood deck joists must meet a Use Class 4 specification to ensure a long service life. >>

OVER THE LAST 7 YEARS OR SO, CAPRICORN ECO TIMBER HAVE BEEN SUPPLYING AND DEVELOPING TIGA WOOD BURNT LARCH, AN INNOVATIVE BLACK CLADDING WHICH IS MAINTENANCE FREE, HAS A VERY LOW CARBON IMPRINT, IS VERY DURABLE AND ECO-FRIENDLY.

Tiga Wood cladding is a bespoke product made to order here at our Stafford factory and sawmill to suit the customers specification, with either a charred and oiled or charred, brushed and oiled finish.

It is coated and sealed with one coat of natural oil which acts as a base and topcoat, the number of coats are dependent on the customers aspirations regarding the longevity of the black colour or whether the cladding is preferred to gradually weather and age-gracefully over the years, if it is the latter no further coats are needed on site after delivery.

The durability of the Larch itself is impressive and it will last 80 years or more in cladding form assuming the usual guidelines for fitting are followed by the installer.

For this reason, the TDCA is appealing to specifiers to ensure their softwood decking substructure components are pressure treated to a Use Class 4 level. Evidence which details the correct treatment has been applied should be provided at purchase point. We have witnessed many cases of unsuitably treated joists being used on outdoor deck structures with bad consequences – it is therefore important to get the specification right.

Roof battens are not the only battens

Roofing and cladding battens are very similar in appearance but are distinctly different. Roofing battens fall into Use Class 2 as they are rarely wet due to the nature of the installation, but cladding battens sit in the Use Class 3 category. ‘Why is that?’ you may ask.

Decking and cladding

Any screw won’t do – get the fixings right

Incorrect fixing is a problem common to both timber decking and timber cladding installation. In fact, where inspections are concerned, nine times out of ten we see incorrect fixing types or placement as a contributory factor to the problems that have arisen. For example, if the fixings are too close to the edges splitting can occur, especially where holes are not predrilled, allowing boards to disengage and lift from their position. Eurocode 5 gives guidance on edge and end distances for softwood and hardwood species.1 n

A FOCUS ON INNOVATION

Linax timber is boiled in hot linseed oil under vacuum, penetrating all six surfaces. This reduces moisture absorption in the wood to provide a dried product with greater resistance to rot and longer colour retention.

This innovative preservation technique means the warranty can be extended, and the maintenance intervals stretched, saving your end users time and money, giving them a superior longer lasting timber for their decking or cladding. *The

Staircases step-by-step: a geometry lesson

Mark Milner delivers an expert, step-by-step (pun intended) guide on how to get the maths right and build a well fitting straight-flight private staircase to recommendations laid down in Approved Document Part K.

The pinnacle of a joiner’s craft, designing and building stairs requires a level of expertise which, once acquired, commands respect amongst colleagues and increases employability and earning potential. With such attributes comes responsibility – mistakes can be very costly and so the importance of ‘getting it right’ cannot be overstated.

Before we look at the steps to getting it right, it will be useful to familiarise ourselves with the main components of a straightflight staircase and basic setting out terms, together with recommendations that apply to a private stair as laid down in The Building Regulations 2010: Approved Document Part K: Protection from falling, collision and impact, 2013 edition (ADK),1 illustrated in Figures 1 and 2 respectively and described below.

Strings: the inclined structural members – the sides of the stair which support the treads and risers. A string can be identified as a ‘wall string’, where the side of a staircase abuts a wall; or an ‘outer string’, where the side of a staircase is exposed.

Newel post: a heavy, vertical member, to which the handrail is connected and the string (usually) tenoned.

Tread: the horizontal part of a step – the part upon which stair users tread.

Riser: the vertical part of a step that provides support to the tread.

Nosing: the moulded front edge of a tread (or landing) which overhangs the face of the riser.

Rise: the vertical distance from the top surface of one tread to the top surface of the next. The maximum permitted rise is 220mm.

Going: the horizontal distance from the tip of one nosing to the tip of the next. The minimum permitted going is 220mm.

The pitch line is an imaginary line which touches all the nosings in a flight. The maximum pitch, measured between a horizontal plane (the floor) and the pitch line, is 42°. Headroom is measured vertically from the pitch line and must be not less than 2m.

As well as specifying maximum and minimum sizes for the rise and going, ADK also stipulates the relationship between the >>

Figure 1: The five main components of a staircase. Image: Mark Milner

Figure 2: Setting out terms and requirements for a private staircase. Image: Mark Milner

two in order to make walking up and down stairs as comfortable as possible. This relationship is expressed as a formula which states that twice the rise plus the going should be not less than 550mm or greater than 700mm, and can be written:

2R + G = 550 to 700 (where R = rise and G = going)

For example, a staircase with a rise of 200mm and a going of 225mm would satisfy this requirement because the sum of twice the rise plus the going does fall between 550mm and 700mm:

2 x 200 + 225 = 625mm

Getting it right: maths for staircase design

Seldom will the answer to this calculation be a whole number. Although our answer is very close to 9, rounding down to the nearest whole number will give us a rise greater than 220mm:

1995 ÷ 9 = 221.7mm

But when we round up to 10:

1995 ÷ 10 = 199.5mm

The answer of 199.5mm is below the permitted maximum of 220mm.

So, having performed two simple calculations we have learnt two things: firstly, how many risers (or steps) there will be (10) and secondly, how high each rise will be (199.5mm). A quick double-check will confirm this:

10 x 199.5 = 1995mm R

Step 2:

Next, we must determine a suitable going to go with our rise of 199.5mm. My method of choice (there are several) is trigonometry because it’s quick, easy, and totally accurate. Using a scientific calculator, the rise is divided by the tangent of 42°:

199.5 ÷ 42 tan = 221.6mm (round to 222mm)

An inverse calculation, using our rounded answer of 222mm should, if correct, produce an answer of just under 42°:

199.5 ÷ 222 = 0.8986 tan –1 = 41.9° R

The secret to a perfect-fitting staircase? Calculations – combining accurate site measurements with the recommendations given in ADK to calculate suitable staircase dimensions.

A new straight-flight staircase from the ground floor up to an intermediate landing is required for a client’s holiday home in Cornwall, and the following describes the design process. In addition to the width, the following site measurements have been recorded and are illustrated in Figure 3:

1. Finished floor to finished floor rise: 1,995mm

2. Limit of horizontal distance at lower floor: 2,642mm

3. Length of stairwell opening: 1,874mm

4. Finished floor to underside of ceiling height: 2,340mm

Step 1:

To work out the rise, we’ll start by dividing the total floor to floor rise (1,995mm) by 220. Why 220? Because 220mm is the maximum permitted rise:

1995 ÷ 220 = 9.1

Space in the client’s holiday cottage is limited and a staircase with a pitch of 42° takes up the least amount of room while complying with ADK’s recommendation.

Step 3: Checking the relationship between the dimensions of the rise and going is quick and easy. Remember the formula:

2R + G = 550 – 700

So, when we substitute the letters R and G in the formula for the rise and going that we have now worked out, we get the following sum:

2 x 199.5 + 222 = 621mm R

621mm is more than 550mm and less that 700mm and ADK’s recommended relationship between the dimensions of the rise and going is satisfied. What’s more, 621mm hits the ‘sweet spot’ of being very close to the midpoint between 550 and 700mm. >>

With continual recognition and awards for our H&S performances and our commitment to Apprenticeships we welcome you to visit our website, call or email us for an informal discussion to see how well we can work with you.

Checking that there’s sufficient headroom – a minimum of 2m – is probably the trickiest part of the process. We’ll start with what we know: we know the staircase can rise up to 340mm and still provide sufficient headroom, because when we take 2,000mm away from the floor-to-ceiling height we get:

2340 – 2000 = 340mm

340mm represents a little less than two risers:

340 ÷ 199.5 = 1.7

As can be seen in Figure 4, at the point where the staircase rises to 340mm, there is around ¾ of one tread (or going), meaning there are a further 8¼ treads between this point and the landing trimmer or trimming joist. If the combined horizontal length of these 8¼ treads, ie 8¼ goings, is less than the length of the stairwell opening (1,874mm), then there will be sufficient headroom. If greater than 1,874mm, the headroom height will be less than the required 2m.

The going for our staircase is 222mm, therefore:

8.25 x 222 = 1831.5mm

The combined horizontal length of the remaining 8¼ steps is less than the stairwell length of 1,874mm, meaning that the available headroom will be greater than the required 2m. Figure 4 also shows that there will be a clear 400mm between the foot of the new staircase and the doorway.

In designing our client’s 10-rise staircase we have demonstrated compliance with the Building Regulations because:

• The rise, at 199.5mm, is less than the maximum 220mm.

• The going, at 222mm, is greater than the minimum 220mm.

• The angle of pitch is (slightly less than) 42°.

• Twice the rise plus the going, at 621mm, is greater than 550mm and less than 700mm.

• Headroom is greater than 2m. n

Adding assurance with third party certification

When first party assurance just isn’t enough

When is a fire door not a fire door? They may look the same, but unless you have assurance that core materials are up to specification, installation is correct, and each doorset will perform to the standard specified by the manufacturer... a doorset with a declared 30-minute fire resistance performance might fail in under 6 minutes!

This is a fire door with first party certification, poor attention to detail and no ongoing maintenance

This fire door was supplied with test evidence to support the fire resistance of the doorset, to meet the regulatory requirements and design intent of the building but under first party certification by the manufacturer.

This is a fire door with third party certification that is well constructed and well maintained

This doorset design was supplied by the manufacturer within the scope of their third party certification, to support the fire resistance of the doorset and to meet the regulatory requirements and design intent of the building.

Exemplifying the value of compliant fire doors in a hypothetical hospital

Progressive horizontal evacuation in a hospital

Progressive horizontal evacuation moves patients and staff away from the fire origin to a safer area on the same level to protect everyone in the short-term and as part of more extensive evacuation steps if required.

Plaut International Ltd have been trading with the UK’s biggest door importers for over 40 years, and in FD30 doors for more than 10 years. We supply doors from factories across Europe and Asia.

We have our own FD30 certificates that have been tested to 476-20:1987, and now offer doors tested to UKAS accredited independent third party certification scheme, Certifire.

There is a wide range of designs and styles that can tailor fit your needs. From veneered or painted flush grooved doors, traditional and contemporary doors to be tailored to classic stile and rail doors, Plaut can accommodate a multitude of constructions.

The newest doors in our offering are Glazed doors and Pairs - both glazed and solid doors are available for Pairs.

We offer global assessments for each test to help extend our range further.

Plaut are also conscious of the environment, so we can offer our doors as PEFC or FSC certified

This is a fire door with first party certification, poor attention to detail and poor ongoing maintenance

When tested, this non-compliant fire door with poor attention to detail and poor ongoing maintenance failed within 6 minutes due to incorrect glazing specifications, which would have compromised the progressive horizontal evacuation strategy. Beyond immediate evacuation issues, more extensive fire damage will result in greater loss of services and disruption in available specialist care, further compromising the integrity of the hospital.

This is a fire door with third party certification that is well constructed and well maintained

When tested, this well constructed, well maintained fire door exceeded the minimum 30-minute requirement, which would have met the requirement of the progressive horizontal evacuation strategy. This strategy relies on a compliant fire door maintaining the fire-resistant compartment lines, to provide sufficient time to move everyone in the immediate vicinity of the fire to a place of relative safety without having to evacuate the entire hospital simultaneously.

Key components of a doorset

A fire-resisting doorset will only provide the required level of fire resistance if all of the components have been tested and demonstrated as being compatible with one another. It is the complete doorset design that provides the required level of fire resistance.

A complete approach to tackling the skills shortage

Skills and talent recruitment must remain a key priority for the construction sector, says Helen Hewitt. Here, she shares different tactics for upskilling the workforce and how to engage the next generation in joinery and woodworking key skills training.

Improving the skills and competencies of professionals in our sector and encouraging the next generation to consider a career in woodworking and joinery manufacture are vital for the future of our industry.

In fact, a report by the Construction Skills Network (CSN) found that the construction industry will need an additional 266,000 workers across a range of occupational areas to meet demand by 2026 – equating to an additional 53,000 recruits each year. Added to this, the CSN highlighted that the largest increases in annual recruitment requirement will be for occupations including carpenters and joiners.

It remains clear that our industry needs to respond to meet growing demand for the services it provides. Skills and talent recruitment are a key priority for the sector and we must continue to raise awareness of the many career paths and opportunities available. We must also support continued professional development and best practice through the provision of appropriate skills and training.

Innovative training provision

As a trade organisation the British Woodworking Federation (BWF) has a large part to play in this. Last year we launched a new package of timber component Interactive Learning Tools (ILT) designed to offer an alternative and innovative method for providing training to individuals. The ILT provides IT-based interactive awareness training and assessment solutions for three learning modules, including the installation of timber fire door assemblies, timber windows and timber stairs.

Launched to BWF members in 2022, the tools use gaming technology, typically used in computer games, to enhance interaction and the learning experience. This method of learning is designed to help the learner visualise what they are doing to create a more practice-based learning experience, rather than simply reading text on a screen. The ILT also incorporates assessment elements to test learning and retention, and issues certificates to successful learners upon completion.

Aiming to close the skills gap for existing installers and support continued professional development, the ILT represents an evolution in training to meet modern training needs.

It’s one example of what we think is needed, urgently, to address the skills gap in our industry.

Engaging the next generation

Upskilling our current workforce is one thing, attracting the next generation is another – but it’s equally vital for the future of our sector. >>

At the start of 2022, we launched a campaign, ‘Our industry’s next generation: Apprentices tell their stories’, championing the role of apprenticeships in the woodworking and joinery manufacturing industry. Through speaking to new and recently qualified apprentices in woodworking and joinery, engineering, and maintenance and operations we learnt about their stories and experiences in the sector. Our interviews with these new employees – which we released as videos publicly – explored why they chose an apprenticeship and career in the industry, what has surprised them most about the profession and what they see as the next step in their career.

As part of this we spoke to Cai, an apprentice at William Holmes. He told us he was pleasantly surprised by what he encountered: “I would have to say the sheer amount of career options within the trade was encouraging to see. There are so many different paths to choose from, which is a really good thing because once you’ve mastered a certain aspect of joinery you can move onto a new challenge – it keeps things interesting.”

We also spoke to Chris, apprentice at George Barnsdale, about why an apprenticeship is a positive route into the woodworking and joinery manufacture industry: “Through an apprenticeship you gain a range of experience in the different areas of the factory, using different skills and tools, which means that you’re able to choose where you work after. This also means that you’re a bigger asset to a company as you have valuable knowledge and skills in all key areas.”

Cai and Chris were representative of many more apprentices who shared positive views. Creativity, the broad range of career paths, and the ability to learn something new every day were recurring themes. Many also highlighted

the benefits of being able to take a hands-on role and apply learning in a practical environment rather than in a classroom.

It’s clear that a career in woodworking and joinery can appeal to a wide and diverse audience, particularly those who do not want to go to university or take an ‘academic’ route following A levels. An apprenticeship offers the ability to learn and develop maths and engineering knowledge as well as problem-solving skills in a workplace environment.

Companies in our profession have long offered apprenticeships in collaboration with further education training providers, and we believe that now, more than ever, apprenticeships can play a key role in tackling the skills shortage.

We also know that we need to engage with the younger generation before they begin to consider and plan their future career. This is where our established schools’ education programme, WOW I MADE THAT, plays a crucial role inspiring students aged 13–18 to consider a career in woodworking and joinery manufacture.

Aligned with the National Curriculum for Design and Technology (D&T) in England for Years 9–12, WOW I MADE THAT introduces students to woodwork and challenges students to research, design, make and evaluate a timber or timber-based product of their choice, including a timber structure, such as a classroom extension or bridge, or a piece of classroom furniture. The programme consists of a scheme of work for teachers, a student workbook and student handouts – since July 2021 there has been 98 downloads of the teacher scheme of works which clearly demonstrates the demand for woodworking educational programmes within schools.

The programme focuses on the importance of embedding sustainable building processes into a project, from the initial design through to product development and completion, and helps students to understand the environmental impact of products throughout their life cycle. Throughout the programme students can also learn about the career opportunities available in the woodworking sector to provide insight into the many rewarding roles available within our industry.

It’s vital that kids of school age, when they are thinking ahead to their careers, have a positive view of woodworking, and we can’t simply rely on people discovering our sector once they leave secondary education.

Driving forward skills and training

The continued and successful growth of our sector is reliant on encouraging the next generation and ensuring that those within the profession continue to strive for best practice. Apprenticeships allow businesses to develop a workforce with skills specific to their business, enable the passing on of knowledge from existing employees and ultimately provide a workforce who are highly motivated to advance and upskill within the sector.

This requires a holistic approach to skills and training, with a diverse offering to inspire those at the beginning of their

careers and support the continued professional development of those already working within the sector.

To ensure the sector continues to grow and thrive year on year, we must find new and innovative solutions to help tackle the skills shortage. Yes, there’s a key role for the BWF here, but it’s vital that all stakeholders – including woodworking and joinery manufacture companies, education groups and further education providers – come together and play their part. There is a huge the opportunity in front of us, but we have to go out there and grab it.

While there remains work to be done, across the UK there are many excellent examples of local and national projects that have been set up to raise awareness of traditional building skills and to make training in those skills more accessible.

Joinery and carpentry skills bootcamps

In 2021, the Government announced £43m form the National Skills Fund to support upskilling and retraining, and expand ‘Skills Bootcamps’ across England. Initially launched in the West Midlands, Greater Manchester, Lancashire and the Liverpool City Region, the bootcamps included building and construction, horticulture and forestry, engineering and environmental conservation. They offer free flexible level 3 qualification courses of 12–16 weeks to those seeking to build up sectorspecific skills suited to specific employment opportunities. Those accepted onto the courses also get help to pay for childcare, travel and other costs.

The National Open College Network offers Level 3 NVQ Diplomas in Wood Occupations (Construction), Bench Joinery, Carpentry and Joinery, or Architectural Joinery, among others, across many locations in England. The free courses for jobs provider list is available online.1

All-Ireland heritage skills

Northern Ireland’s Heritage Skills Fund Traditional Building Skills Initiative aims to improve and promote traditional building skills as a career, as well as improve public awareness. Funding is available for workshops, field trips and other training opportunities covering traditional skills such as joinery. To qualify for funding, the primary aim of the course must be educational and focused on traditional buildings.2

In July 2020, the Department for Communities’ Historic Environment Division (HED) partnered with The Prince’s Foundation to launch the NI Heritage Skills Programme.3 Preserving the traditional wisdom and knowledge embodied by the nation’s built environment, the programme provides opportunities for trainees to work with experienced mentors, gaining the skills required to become the next generation master craftspeople. >>

“Northern Ireland’s Heritage Skills Fund Traditional Building Skills Initiative aims to improve and promote traditional building skills as a career, as well as improve public awareness. ”

George Irwin MBE, a conservation joiner at the Department for Communities with over 44 years’ experience said: “I have a passion for working on old buildings and using traditional construction methods to fabricate items which will remain for years to come. It is vitally important that we preserve and prevent the loss of our historical assets and pass on these traditional skills to maintain our historic environment.”

Working with all ages and backgrounds, The Prince’s Foundation helps pioneer ideas, championing sustainable farming and heritage-led regeneration. While the organisation focuses on the regeneration of the Dumfries House estate and wider community, the work takes a broad view both nationally and internationally to help create a more sustainable future.

The All-Ireland Heritage Skills Programme is a full-time, 12-month course in heritage building skills, which includes a Level 3 NVQ Diploma in Heritage Skills (Construction). The course includes practical experience in carpentry and joinery as well as many other traditional building crafts such as stonemasonry, blacksmithing and thatching.

Wood to Work as a Way into Work

Launched in October 2021, Wood to Work is a partnership between Ways to Work, Oxford Wood Recycling and Oxfordshire Employment.4 The scheme trains individuals facing significant barriers to employment, including health or disability, in work-related wood shop skills. The programme includes health and safety training and relevant PPE, and is aimed at breaking down the barriers to employment opportunities.

Volunteers work with experts at the Abingdon Wood Shop using reclaimed wood to make solid wood furniture. The

results are sustainable and beautiful. The collection includes stools and tables, benches, bookcases, shelves, racks, barrels and boot stores. The final items use a selection of wood finishes that enhance the final product for use either indoors or outdoors.

“We are seeing an increase in enquiries from public sector and corporate clients wishing to include recycled and reclaimed materials in their projects. For us this has particular resonance in the use of reclaimed timber for production of outdoor furniture for street and leisure areas. In 2022 we quoted for planters, benches, acoustic screening and boardwalks and predict this to be a growth area, and an opportunity for community wood recyclers nationally as suppliers and manufacturers,” said Richard Snow, CEO, Oxford Wood Recycling.

Eight volunteers currently benefit from the valuable experience they gain in the workshop, which they can add to their CVs. Once settled into the programme, the Ways into Work Senior Employment Coach (SEC) assists with CVs and begins job matching individuals with suitable vacancies. Several volunteers now look forward to starting paid employment.

Traditional skills and conservation training centres

In Scotland, the Historic Environment Recovery Fund offers £2.6m across two streams: to support reopening historic buildings and sites, and sector resilience and recovery. As part of this second stream, funding is also available for those delivering traditional skills training courses.

Built using a National Lottery Heritage Fund grant, the Engine Shed in Scotland was purpose built to encourage building conservation and increase awareness of traditional building materials and skills among both the public and professionals. Part of Historic Environment Scotland, the centre promotes the care and maintenance of the build environment using cuttingedge technology and traditional skills.5

Dedicated training centres in Elgin and Stirling offer nationally recognised, accredited and approved courses to apprentices and craft fellows specifically aimed assisting the transition to a low-carbon economy and net zero by addressing the traditional skills shortage. Owners of traditional buildings can seek advice, learn how to solve common problems and gain insights into the use of traditional materials.

Since 2021, the enlarged site in Stirling offers conservation science, innovative 3D digital documentation of Scotland’s built environment heritage, and technical outreach and public education both at the Engine Shed and across Scotland.

Traditional skills training in Wales

There is also a host of funding schemes to support training and learning in Wales, from the Business Wales Skills Gateway, apprenticeships and traineeships, ReAct and Jobs Growth Wales, through to the Communities for Work intensive mentoring for the unemployed, low-income or at-risk individuals facing complex barriers to employment.

Y Dref Werdd, an environmental community organisation based in Blaenau Ffestiniog in North Wales,6 used Welsh European Funding Office (WEFO) Skyline project funding to construct a traditional skills training centre. The Skyline project aims to use local resources for the benefit of communities.

Joinery Skills

Designed by local craftsmen Wil Gritten and Hefin Hamer, the new traditional skills centre is a 6 x 6 x 4m octagonal timber structure built from 25 tonnes of Douglas fir. The timber was grown and felled near Llyn Vyrnwy and milled using a Wood-Mizer owned and operated by locals George and Lois Wynne-Williams.

The structure was built around eight 6 x 6in timber columns, with four trusses around a central king post supporting the roof. Because the timber was sourced and milled locally, the craftsmen were able to specify their own components and so enjoyed the luxury of laying 400 x 30mm floorboards and cladding the walls with 300 x 20mm boards.

“The final construction of the floor came about through a mistake,” explained Wil. “I’d laid half the joists, but then got Covid. Then Hef laid the rest of them perpendicular to the others, so we ended up with a unique four quartered floor.”

Wil continued, “The building is nearly done and will be used to teach traditional skills to locals. There’s already a long list of things people want to learn – as well as the usual green woodworking, joinery and basketmaking, it includes a request for cocktail-making classes from the ladies at the Antur Stiniog cafe and one from the kids in the youth club for making longbows.” n

Understanding product certification and markings

An interview with Hugh Mansfield-Williams

With repeatedly changing goal posts, it can be difficult to keep up with new rules around the adoption of UKCA (UK Conformity Assessed)-marking for Construction product

Hugh Mansfieldlays out the current situation.

ith more than 15 years’ experience as a Technical Manager at BM TRADA, Hugh’s core responsibilities include conducting technical assessments for construction products in relation to -Mark Certification Scheme, the European CE Marking Scheme, and more recently the UKCA Marking Certification Scheme. As a representative of BM TRADA at various Technical Committees, Standard ugh has deep insight into construction products and compliance requirements.

ere, we ask Hugh for his expert guidance on the adoption of UKCA (UK Conformity Assessed) marking and what UK construction product manufacturers and timber suppliers

What is CE marking and why is it important for timber suppliers?

he CE mark on a product indicates that the manufacturer or importer of that product affirms its compliance with the relevant EU legislation and that the product may be sold anywhere in the European Economic Area. A CE mark also signifies that a product has been assessed by the manufacturer, usually via an independent Notified Body and is deemed to meet EU Regulations/ requirements. >>

CE marking is a mandatory requirement for qualifying products manufactured anywhere in the world which are placed on the EU market. Construction products can only be CE marked and placed on the market if the manufacturer maintains a Factory Production Control (FPC) system.

Not all products require CE marking. Only those products or product categories subject to relevant Directives and Regulations, such as the European Construction Products Regulation 305 (ECPR)1 for construction products, need to bear the CE mark.

For example, if I was going to buy timber to build a house in Spain, I would be looking for a CE mark since most structural timber is within the scope of a Harmonized European Standard, EN 14081. The ‘CE mark’ is often on each individual piece of timber, but where this is not possible, it may be on the packaging. If the timber does not have packaging, then the CE mark must be supplied with the accompanying documentation. The CE marking must refer to the manufacturer’s Declaration of Performance (DoP) for the product which may be supplied with the product, or may be available on a website.

Q: So, what is UKCA (UK Conformity Assessed) marking?

UKCA is the equivalent of CE and is a requirement of Great Britain. CE marking belongs to a European Regulation, the EU CPR,1 while UKCA belongs to a UK Regulation, the UK CPR.

Like CE marking, UKCA marking on a product indicates that the manufacturer or importer of that product affirms its compliance with UK legislation and the product may be sold on the Great Britain market. The UKCA mark also indicates that the product has been assessed by the manufacturer, usually via an independent Approved Body, and is deemed to meet UK Regulations/requirements.

Only those products or product categories that fall within the scope of a Designated Standard or other technical specification cited under the UK Construction Products Regulations2 are required or allowed to bear the UKCA marking. Just like CE marking, UKCA marked products can only be placed on the market if the manufacturer maintains an FPC system.

Currently, the requirements for UKCA and CE are identical from a ‘technical perspective’ since the same technical specifications/ standards are used for both UKCA and CE marking, but divergence is expected in future. For UKCA, the main technical specifications are BS EN standards referred to as ‘Designated’ standards, while for CE marking the same standards are called ‘Harmonized’ standards. However, both still bear ‘EN’ in the title.

Note that for CE marking, an EU Notified Body is required and for UKCA marking a UK Approved Body performs the same function.

Q: Does UKCA marking cover all devolved nations?

UKCA marking only applies to Great Britain (England, Scotland and Wales). CE marking still applies to products placed on the market in Northern Ireland and the Republic of Ireland. So, if a manufacturer, importer or distributor wishes to sell its product in the Republic of Ireland or Northern Ireland, it still needs to comply with CE marking requirements.

Q: What are the key points of difference between CE and UKCA marking requirements?

Currently, the only difference between CE and UKCA marking is the mark itself. The EU has the ‘CE’ mark and the UK has the equivalent ‘UKCA’ mark. As mentioned earlier, the same technical specification/standard is being used for both CE and UKCA marking. For the EU, it is referred to as a Harmonized Standard and for the UK it is referred to as a Designated Standard. From a technical perspective, the requirements for CE and UKCA are currently exactly the same, but divergence is expected in future as the UK and the EU evolve and each develops its own national requirements.

Q: As a timber supplier, how can I ensure my products comply with both CE and UKCA marking legislation?

It is a legal requirement for manufacturers of construction products to ensure that the product is tested and certified in accordance with the applicable Harmonized or Designated Standard. As manufacturers, they must ensure they are familiar with both the Regulation and the Standard or Standards that are in place for their products.

Importers and distributors have a responsibility to ensure that they only supply products from manufacturers who have complied with the regulatory requirements applicable in the market in which they want to sell their product. >>

“Just like CE marking, UKCA marking is a crucial procedure that guarantees the product conforms to UK Regulations and it is therefore mandatory for manufacturers, importers and distributors to fulfil their responsibilities. ”

Product certification relies on a chain of custody approach, where each person/entity in the chain has a responsibility to ensure that the product complies with the applicable regulatory requirements in the market in which it’s being sold, and that no changes are made to the product that would invalidate the manufacturer’s Declaration of Performance.

I deal with the assessments and certification of construction products. If anyone is unsure as to what they need to do, they can drop me or the Product Certification team a line. We can advise on what is required for the product in terms of certification and point them in the direction of someone who can assist with testing if it is required.

Q: How can timber suppliers keep abreast of legislative updates?

With the current changes and intricacies related to CE and UKCA marking, not all websites provide the most accurate information. We always refer people to the relevant UK government websites for UKCA marking updates3,4 and the European Commission’s NANDO database,5 for CE marking as we find that these websites have the most current and up-to-date information.

Approved/Notified Bodies normally provide updates and information to their customers. If you are certificate holder with BM TRADA, for example, and there is a change in requirements or legislation that will affect the way you manufacture or market your product, you will normally receive information or correspondence from us regarding the changes. n

For advice on your specific product certification requirements contact BM TRADA’s Technical Helpline on +44 (0)1494 569601 or email timberadvice@bmtrada.com

Key points to remember

• Most construction products fall within the scope of a Designated or Harmonized Standard.

• If a product falls within the scope of a Designated or Harmonized Standard, then it is a legal requirement for the manufacturer to test and certify the product in accordance with the requirements of that standard.

• A manufacturer will need to identify whether its product falls within the scope of a Designated or Harmonized Standard and ensure that it meets the regulatory requirements applicable in the market in which it wishes to place the product.

• For most products that fall within the scope of a Harmonized or Designated Standard, the manufacturer will need to engage the services of a Notified or Approved Certification or Test Body to carry out the required certification or testing activities.

• Once the product is tested and certified, the manufacturer will need to ensure that the product is appropriately marked and that it has produced the Declaration of Performance (DoP) before placing it on the market.

“Product certification is seen as a chain of custody approach, where each person/entity in the chain has an equal responsibility to ensure that the product complies to the regulatory requirements that are applicable in the market in which it’s being sold.”

Douglas fir: the wood of the future

As UK and European stocks of Douglas fir begin to reach maturity following increased planting over the past 75 years, Sabrina Pedrono of France Douglas and Elisabeth Piveteau-Boley of Piveteaubois look at the wealth of application of this versatile species.

In 2020, Douglas fir represented less than 3% of the French forest area but 18% of French sawnwood. In 15 years, it could represent a third of the total national softwood production.

Timber for construction

Since its introduction to Europe from the American West, Douglas fir has become one of the mainstays of the timber sector with the forest area constantly expanding. Strong, hard, workable and abrasion resistant, Douglas fir is a highly versatile structural timber as well as being useful for cladding and external landscaping.

Douglas fir: the species

Introduced into the UK in 1827 by botanist David Douglas, Douglas fir is, in fact, a conifer that grows well in open forest and thrives in damp conditions. ‘Douglasfir’ is traditionally written as one word, without a hyphen, to indicate that it is not a true fir but modern language has adopted the use of two words.

The species is perfectly adapted to mid-mountain areas and grows well in hardiness zones 4–6. An evergreen with resinfilled blisters on its red-brown, corky trunk, three-pointed cones with scales, and flat, soft, flexible needle-like leaves, Douglas fir grows at a medium rate of up to one metre per annum and can live for up to 500 years. Carrying both male and female cones on the same tree, Douglas fir is wind pollinated. In ideal conditions, mature trees will grow to heights of 12–21 metres with spreads of 4–6 metres when mature.

There are two main varieties of Douglas fir: the coast Douglas fir (Pseudotsuga menziesii var. menziesii) and the Rocky Mountain Douglas fir (Pseudotsuga menziesii var. glauca). The first has dark, yellow-green or bluish-green needles, grows faster and lives longer. The second has shorter, bluish-green needles and is slower growing and hardier, but rarely grows over 39 metres tall.

Douglas fir: in UK and Europe

Douglas fir covers almost 20 million hectares of western North America. When imported from North America it is sold as ‘Oregon pine’. Initially brought to Europe as an ornamental tree in 1827, it was gradually introduced to the forests of Europe after the Second World War. As a result of the reforestation programmes set up in France, Douglas fir now covers 426,000 hectares of the country. The species also thrives in the western areas of the UK, where rainfall is high >>

“As renewable material with both excellent properties of natural durability and mechanical performance, Douglas fir is perfectly placed for a wide range of applications: structural use, cladding, decking, interior decoration, exterior fittings – even works of art.”

Douglas fir decking at Clifford’s Tower

The free-standing timber viewing deck inside Clifford’s Tower, an English Heritage castle overlooking Old York, was designed by Hugh Broughton Associates and built by Simpson York. Accessed by new walkways and legacy staircases, the deck was opened in April 2022 to give visitors spectacular panoramic views over York’s skyline. Constructed to protect the tower’s historic stonework, the structure includes primary steel flitch beams and secondary glulam joists that make up 14 enormous structural timber frame sections, all manufactured using C24 sapwood-free Douglas fir from Piveteaubois. These include four columns, each 550mm square and 9m high. The platform was then covered in Douglas fir decking sealed with Liberon decking oil. Buckland Timber manufactures glulam from both UK-grown and imported French Douglas fir and occasionally from North American Douglas fir.

As UK and European Douglas fir forests gradually mature, timber harvests increase significantly. In France alone harvests exceeded 3 million cubic metres in 2020. When reaching full potential around 2035, production is expected to deliver 6 million cubic metres of roundwood each year – more than 30% of France’s national softwood production. This makes Douglas fir the top emerging timber resource in France, yielding very straight trees that grow up to 50m tall.

Douglas fir: the structural timber

As renewable material with both excellent properties of natural durability and mechanical performance, Douglas fir is perfectly placed for a wide range of applications: structural use, cladding, decking, interior decoration, exterior fittings – even works of art. It offers great architectural freedom, is easy to work with and boasts a high level of dimensional stability. All these benefits make it appealing to architects, building designers, structural engineers and the joinery sector.

PEFC-certified Douglas fir CLT at the Chelsea Flower Show

Designed by Robert Myers and built by landscapers Bowles & Wyer for the 2021 RHS Chelsea Flower Show, the Florence Nightingale Garden showcased an eco-friendly PEFC-certified CLT timber pergola. This 60ft pergola, made of sapwood-free Douglas fir from Piveteaubois, was constructed off-site and assembled by ConstrucktCLT on site in a matter of days. The complex geometry of each individual timber profile was templated by ConstrucktCLT. The curved structural CLT ribs were then cut to shape by Constructional Timber (Manufacturers) Ltd. The garden was dismantled after the show and transported to its permanent home at Guy’s and St Thomas’ Hospital, London where it will be part of the restorative garden for the recuperation of patients.

Timber in construction must meet certain requirements of structural stability and durability to insect or fungal attack. Douglas fir heartwood is reddish-brown and highly distinct from its cream white sapwood. While specifiers should refer to standards to ensure the desired service life is achieved, when out of ground contact the heartwood can be used in exterior applications. This opens up significant additional areas of exterior architectural use, including cladding, decking, and applications in high moisture atmospheres such as swimming pool halls.

Douglas fir timbers grown in the UK can have less resin than North American wood, offering average graded weights when dry of around 530 kg/m3 Once dry, it becomes very hard. Characteristic strength ranges from about 10 to 25 N/mm2 with mean stiffness ranging between 8 to 13 kN/mm2 The variability in UK growth rates give lower density rates than European grown timbers but characteristic properties are quickly improved by grading, with grades of C24 and C28 readily available. >>

A softwood with long, straight fibres and a medium texture, Douglas fir offers excellent resistance to traction and bending, with a high weight/resistance ratio. Although the presence of a high number of knots can weaken this mechanical resistance, fewer knots are found in the heartwood and this issue can be minimised further when modifying the wood into cross laminated timber (CLT) or glulam, for example. Its timber characteristics make Douglas fir good for glueing, sawing, nailing and screwing, although a tendency for splitting means pre-drilling is necessary.

Douglas fir: a flexible, technical, economic and environmental option

Timber in construction has undergone many changes in recent years, moving from a demand-based model of delivering individual homes, to huge growth markets such as social housing, retail and commercial buildings, or multi-storey ‘tall timber’ buildings. These markets require highly technical and engineered products such as CLT and glulam – an area where Douglas fir is already common.

Douglas fir glulam at Bristol Old Vic

The £9.3m refurbishment of the Bristol Old Vic by Haworth Tompkins was the result of five years of careful research, design and construction. Framed in PEFCcertified, structural Douglas fir glulam, flitched and with bolts expressed, the new foyer has been designed with a large intake plenum and pre-cooling ‘labyrinth’ with automated, thermosensitive control of low- and highlevel openings with shutters allowing natural light and ventilation to fill the space. The contemporary foyer and roof incorporate 59m3 machined and cut-to-size GL24h Douglas fir glulam designed, manufactured, supplied and installed by Constructional Timber (Manufacturers) Ltd. The timber will naturally bend, flex and darken with age. Designed to span in one direction, the roof beams are short spans linked with RICON® connectors to give tight, angular joints with horizontal plywood bracing. Only the largest spans required steel reinforcement.

Douglas fir: a source of architectural inspiration

Douglas fir products are constantly evolving to meet the needs of the construction market with high-profile landmark projects appearing across the UK and Europe. These projects – through their diversity, building systems, number of components, finishes or aesthetics, all help contribute to the transition towards the circular economy and net zero construction. n

GHANA FORESTRY COMMISSION’S SEARCH FOR PRIVATE SECTOR ‘PARTNERSHIP IN ECOTOURISM’

In the current and almost universal climate of government competing needs; funding shortages and over-stretched budgets, many governments especially in developing countries, are hard-pressed for finding sufficient money to respond to wildlife conservation efforts in their countries. Other key sectors, such as health, education and roads, impose a huge amount of inter-sectoral competition for the limited state funds and always succeed in securing the biggest portion of government resources.

The situation consequently, imposes more and more challenges for many such governments to protect wildlife resources in parks and reserves adequately.

As most visitors demand overnight facilities and visitor support services in order to maximize positive experiences within these parks, Ghana Government has taken initial steps to provide some of these facilities.

The private sector widely known for possessing capital and management expertise to build and run facilities and services that meet the expectations and demands of today’s tourists, is required to undertake necessary investments that respond quickly and effectively to prevailing market forces and trends.

The Ghana Forestry Commission therefore recognises that, for wildlife conservation to succeed into the future and especially in the prevailing and likely future economic environments – it is absolutely essential to enter into ‘partnership in Ecotourism’ with experienced and innovative private sector investors and tourism operators who are keen and able to develop and operate a range of quality tourism facilities in Ghana’s wildlife tourism areas. These investments include provision of:

• Chalet Camps: 260 bed lower-to middle-market

• Eco-lodges: 180 bed middle-to upper-market

• Floating Lodge: 50 bed middle-to upper-market

• Corporate Guest lodges: 40 bed luxury market, private

• Other additional facilities and services such as bush camps, tree-houses, canoeing, flights etc.

The Ghana government represented by the Forestry Commission believes that by investing in wildlife tourism in the country’s protected forests, investors and operators have ideal opportunities to establish profitable businesses to benefit from the country’s young, rich and diverse historical and cultural heritage; an emerging and increasingly popular tourism niche, and capitalise on an already existing market of visitors and tourists both within and outside Ghana.

Timber in the circular economy

As a natural resource, timber is set to play a significant role in the future of our built environment, offering enormous potential within a new circular approach to construction sector resources and best practices.

According to the Ellen MacArthur Foundation,1 the circular economy offers environmental, business and social resilience by decoupling economic activity from the consumption of finite resources. The circular framework relies on the principles of designing out waste and pollution, keeping products and materials in use, and regenerating natural systems. This is in stark contrast to the current built environment model, which is highly linear, traditionally relying on the manufacture and use of new materials and producing vast amounts of construction, demolition and excavation waste.

While timber distributors will always want to sell new timber, reclamation has always had an accepted role within the marketplace. However, despite these good foundations, we are still at the beginning of true transformation, with many challenges yet to be faced and a great deal still open for discussion. Here, BM TRADA looks at some current research and poses a few key questions to industry experts, asking how we might begin to tackle the challenges faced when attempting to maximise the service life of timber.

What are the challenges of timber waste reduction and reuse?

Alastair Kerr, Director General of the Wood Panel Industries Federation2 said:

“There is a very well-established system for the collection and processing of waste wood from construction, household waste and industrial waste wood. Waste wood from these sources provides an invaluable raw material input for the manufacture of chipboard. At the end of life, chipboard can also be recycled. Wood-based panels grew out of a need to use smaller dimension forestry wood and residues from the sawmilling sector. By reconstituting wood fibre/chips etc into standardised panels, they help to reduce waste.

“Reducing timber waste in construction is more problematic. Off-site construction helps to optimise material use and in doing so reduces waste. Reuse is probably the most challenging aspect because the majority of timber and wood-based products are installed as a component of larger systems and in order to meet the technical demands of the application, materials within these systems tend to be rigidly fixed, making disassembly without damage to the components nearly impossible.

“Prefabricated system components could potentially be reused but if they have been in for the life of the building, it’s unlikely that anyone would want to pay the costs necessary to segregate out materials undamaged.”

Reusable design and construction

Project InFutUReWood was led by RISE (Research Institutes of Sweden) under the umbrella of ERANET Cofund ForestValue. According to the project report, its mission was to answer the question: ‘How should we build today to be able to circulate tomorrow?’. The scope of the project was the reuse of structural timber from current buildings and how current and past experience of demolition might help the design of timber buildings (1–3 storey) to facilitate future deconstruction and new products out of recovered wood. The primary focus for new products was sawn and laminated structural timber.3 >>

Here we look at current research and open discussion around how we might tackle problems faced when maximising the service life of timbers as the construction industry learns to embrace a more circular economy.

GP Wood was formed in April 2013 as a result of the merger of two of Ireland’s most successful and long established timber processing companies; Grainger Sawmills Ltd and Palfab Ltd, both based in County Cork.

Now, RISE is leading the Design for the Future - Reuse of Timber Buildings in a Circular Economy study which aims to develop demountable and reusable wooden buildings based on environmental impact calculations and collaboration across players throughout the construction and demolition supply chain.4 Researchers and industrial partners are currently developing two demonstrators with design for deconstruction and reuse in mind. One is a modular building and the second is a flexible timber building. The project principals look forward to publishing their results later this year.

The secondary timber value chain

In their paper, A Shed Resource: A look at wood recycling in the UK,5 Marlene Cramer and Daniel Ridley-Ellis of Edinburgh Napier University explored the secondary timber value chain and the future of timber in the circular economy by interviewing community wood recyclers, chip producers and board making companies.

For their report, Cramer and Ridley-Ellis spoke with seven UK wood recycling companies, whom they believe represent a good cross-section of the sector. These companies collect and process a mix of waste wood that includes used and unused solid timber and board products rejected or reclaimed from sawmills and construction sites and pre-used products like furniture and whisky barrels.

“On our way to a more circular, bio-based economy, we will need to start treating recycled timber as a more valuable

resource,” explain the authors. “In a perfect world, your garden shed might serve as a dinner table, before it gets chipped and lives again as a kitchen top, possibly again as a flooring board, and finally provides heat for your grandchildren’s home, when it is incinerated at the end of its life. But what happens in reality?” they ask.

Cramer and Ridley-Ellis conclude: “None of the companies sees particular problems in processing recovered material, since existing contaminations are manageable. For these companies it is business as usual to remove all the nails, paint and concrete that is adjacent to the parts of your garden shed and most of these processes are automated. On the other hand, none of the companies sees a potential for higher value products made from the material they receive. The timber is mostly damaged and mixed with other materials from the demolition process or earlier use.”

However, the report also notes that; “The big companies for wood recycling are not receiving any government support for their circular material use.” And that, “The varying prices for the recovery notes are therefore problematic.”

What is the current level of timber recycling in the UK?

Despite these challenges, Julia Turner, Executive Director at the Wood Recyclers’ Association, said:

“The level of wood that is recycled and recovered in the UK has gone up considerably over the last two decades, with the industry now an exemplar of best practice in the UK circular economy. Our annual waste wood statistics show that in 2021, of the 4.5 million tonnes of waste wood collected in the UK, over 4 million tonnes were processed. Of this, roughly a third (34%) was sent for reuse or recycling, to markets such as panel board, equine surfaces and animal bedding, while around two-thirds (66%), was sent to small-scale biomass, exported, or used in large-scale biomass plants to generate baseload domestic renewable energy.

“With regards to recycling, the panel board sector – the largest user of recycled wood in the UK – increased its usage of >>

waste wood by 10% on the previous year, reaching a record high of 1.08 million tonnes.

“We expect that even more waste wood will be processed this year, as we now have valuable end markets for all waste wood. This shows how far the waste wood industry has come since 2008 when the majority of waste wood was sent to landfill.”

Cross-laminated secondary timber

Dr Colin Rose is a Senior Research Fellow at University College London (UCL), Strategic Advisor for the Built Environment at ReLondon, where he contributes to the CIRCuIT project, and founding partner of UK CLT LLP. Having won Ramboll’s Flemming Bligaard Award 2020, he leads circular economy research at UCL investigating the use of secondary timber.

“Reuse is a challenging aspect of circularity; with timber, it’s far easier to chip it and incinerate or downcycle. What we mean by downcycling is that the qualities of, say, 19th-Century floor joists are lost when you turn them into panel boards or animal bedding. Many demolished buildings contain large quantities of joists, studs and rafters that could be reused, but are typically skipped. We refer to these materials as secondary timber,” Rose continues, “because they don’t need to be thought of as waste. They often retain structural as well as aesthetic qualities, so the challenge is to put that to use in a practical and valuable way.”

“With cross-laminated secondary timber (CLST), we’re aiming to upcycle wood into a standardised and recertified product that meets the requirements of the mainstream construction industry. As a low-carbon alternative to concrete and steel, CLST achieves long-term carbon capture and storage beyond timber’s first use. Furthermore, it can be designed for future deconstruction and reuse, before eventually becoming chipboard and biomass.”

“We share the wood recyclers’ goal of creating a more circular timber industry. There’s a lot of work to do before we’ve optimised our use of secondary timber, but it’s fantastic to see growing interest from academia and industry in its potential for production of engineered wood products.”

The sustainability of refinished wood floors

Wood is a sustainable material and has long been valued for its appearance, providing texture, colour and lustre, together with excellent wear resistance enhanced through coating. Alec Stacey discusses new research from Sweden that suggests another benefit of wood flooring is that it can be refinished, extending the service life of a floor.

In 2019, IVL Swedish Environmental Research Institute (IVL), sought to understand the environmental impact of refinishing compared to replacing flooring materials. Founded in 1966, IVL is a Sweden-based environmental research agency that studies the holistic interaction between the environment, economy, business and society. The 12-month study it conducted looked at the impact of refinishing versus replacing hardwood flooring in commercial buildings throughout Sweden.

Every year, 25 million square metres of new flooring is installed in Sweden, some of which is for the replacement of existing flooring. This is important since building and construction accounts for one-fifth of Sweden’s climate impact and examining ways to reduce this is important. This provides the background for the research project. It is likely that what happens in Sweden is reflected in other countries of a similar size and demographic.

IVL invited Bona, headquartered in Malmö, Sweden, to participate in the 12-month study, with the caveat that all findings would be shared publicly. IVL reviewed several refinishing systems as part of the project. The study, Increasing Resource Efficiency in the Swedish Flooring Industry Through Floor Refinishing,1 began with a life cycle analysis (LCA) of the floor installation and refinishing process. The outcome of this analysis was compared to the impact of producing and installing new flooring in terms of both climate change and resource use. The study was a cradle-to-grave assessment, which means the whole life cycle for refinished and new flooring was considered. This included extraction, production, and transportation of raw materials and products, installation of flooring and refinishing, as well as end-of-life management. The study did not include the impact from floor maintenance and cleaning. IVL used the Bona System for assessing wood floor refinishing and the Bona Commercial System for PVC/ resilient floor refinishing.

Initial study results offered proof of concept, demonstrating that refinishing a floor can indeed reduce the impact of climate change and minimise resource use compared to producing and installing new flooring. >>

“Refinishing a wood floor saves 79% more carbon emissions than replacing the flooring surface. Refinishing resilient floor surfaces can offer up to 92% reduction in carbon footprint versus replacing.”

Materials Timber flooring

In the second part of the study, a roadmap was developed in collaboration with stakeholders from the flooring industry including material suppliers, property owners, architects, and contractors. The roadmap outlines a strategic plan that defines outcomes and outlines important actions needed to overcome barriers to adoption of floor refinishing as a sustainable alternative to installing new floors.

In 2020, IVL released its findings. Refinishing a wood floor saves 79% more carbon emissions than replacing the flooring surface. Refinishing resilient floor surfaces can offer up to 92% reduction in carbon footprint versus replacing. Additionally, refinishing hardwood or resilient floors offers a 95% saving in energy resources, which is measured by transportation, electricity use, consumables, and materials.1

Even more value for wood flooring

The IVL report provides further evidence about the benefits of using wood floors. The demand for sustainable building and renovation is increasing in market value and homeowner interest. A report from The Insight Partners projects that the European Green Building Market is expected to reach €124.7bn by 2028. Wood is a primary material for many sustainable building projects, and the IVL data lends another perspective to wood’s longevity and environmental value.

Additionally, the demand from local and national governmental bodies and regulators for more green buildings is sharply on the rise. While the shorter-term focus is typically on energy efficiency, carbon emissions resulting from product manufacture, use and disposal (embodied carbon) is becoming increasingly important.

While other flooring made from recycled materials may claim sustainability, it often has a shorter lifespan. Once the material is worn or damaged, it is typically torn out, tossed into a landfill, and replaced with a new floor. As the IVL study proves, tearing out and replacing flooring material has a much greater impact on carbon emissions than refurbishing existing floors.

“The norm today is new and fresh. Sales of new flooring material is supported by the linear business model we have in the construction industry today and refinishing is often perceived as more difficult,” said Maria Ahlm, author of the report at the IVL Swedish Environmental Institute. “However, our analysis and final roadmap support that in addition to the decrease in carbon footprint, floor refinishing is a viable alternative to increase resource efficiency in the Swedish flooring industry.”

The report also supports new wood floor installation since well-designed, manufactured wood floors not only offer a beautiful, natural aesthetic, but a floor can be sustainably refreshed and refinished to provide an extended service life.

The timeless beauty of a wood floor is now supported by the many sustainable attributes of the material. With proper forest management, trees are planted before others are harvested, allowing wood floors to be an environmentally friendly option for generations of floor owners. Coupled with the longstanding data supporting the environmental value of wood, this new study adds another valuable perspective. Wood offers promise for a greener, more sustainable future. n
