Willmott Dixon is merging all of its group residential activities together under a new company brand. Willmott Residential will be led by former Berkeley Group finance director Nick Simpkin who joins as chief executive. The new operation will contain the contractor’s two development brands – Prime Place and Be:here, – with its newly branded contract housing arm Willmott Partnership Homes. Willmott Dixon group chief executive Rick Willmott said: “The launch of Willmott Residential provides clear differentiation in the way we now present and manage the group and underlines how serious we are in growing our residential presence. “The company will provide an integrated business for our wide ranging residential skill-sets with better internal collaboration and utilisation of synergies.

“Nick brings a long track-record of success in housing development during his time at Berkeley and will lead a fine senior leadership team supported by Andrew Telfer who has been pivotal in growing our development capability over the last seven years. “I’m delighted that Nick has chosen to join us; it’s a testament to the huge potential he sees in our residential capability. “I’m confident he’ll provide the strategic fire power we need to grow our residential business and I’m very much looking forward to working with him.” Willmott Residential already has a significant presence in the market developing homes for sale through Prime Place and private rent through Be:here, with 5,000 units on site or in planning.

In addition Willmott Partnership Homes already builds 2,000 homes a year with an expanding geographic presence and strong client base that includes housing associations, developers and local authorities. Willmott added: “Given the country’s huge long-term demand for new homes, we have a golden opportunity to be one of the UK’s pre-eminent developers and builders of homes, and these plans will ensure we are best placed to realise that. “By aligning our residential business within one company and creating a distinct identity, Willmott Residential will ensure we are equipped to realise our ambitions and seize the opportunity for expansion created by the hard work of our teams at Prime Place, Be:here and Willmott Partnership Homes.”

made for reasons of safe-guarding employee welfare and the preservation of critical evidence.

Coleman and Company boss Mark Coleman said he was “so disappointed” at “a decision which prevents us recovering our men.”

‘We understand these reasons and our immediate focus is to ensure that we continue with the recovery operation for as long as we are permitted and at the same time, work collaboratively to facilitate a seamless transition so that the recovery operation going forward proceeds without delay.

A company statement said: “We have now reached a stage where we will be handing over the remaining recovery operation to another contractor within the next few weeks. “This is of course hugely disappointing as we all wanted to recover our friends and colleagues and return them to their families. “We wish to make it clear that this decision in no way diminishes the excellent work that everyone involved in supporting the recovery has done. “The praise we have received from RWE, the Police and HSE for how we have conducted the recovery since it began, in these tragic and difficult circumstances, reflects the dedication and commitment we have to each other and the business.

“While the sequence of future recovery operations is not our decision, all stakeholders are agreed that the safety of those involved in the process going forward is of paramount importance. “We will remain on-site as Principal Contractor, for the wider site, and over the coming weeks we will play an active role in supporting the recovery by working collaboratively with a team of industry experts, assisting in any way we can. “Once the recovery is complete we hope to resume our works to complete the contract.” Specialist website Demolition News understands that Brown and Mason will be the replacement contractor.

Lakeside Calling Card If you’re Dan Feidt, AIA, principal of Dan Feidt Studio, an Excelsior, Minn.-based residential architect, it’s an exacting one. The subject property is his home. But as the renovation soon proved, it’s also a high-profile calling card for his residential design practice. That may not have been the intended effect, but it’s certainly been one of the project’s many happy consequences. “The house is on a beautiful location, on the southern shore of Lake Minnetonka, about 20 miles west of Minneapolis. It was built in 1955. Some remodeling work was done in 1965 but not much since. We actually considered tearing it down and rebuilding, which is fairly common here,” Feidt says. Feidt estimates they saved about 25 percent on the cost of building new. Nonetheless, the renovations were massive. “We took it right down to the studs. New siding. New maple floor and cabinets. New butterfly roof. New doors. New mechanicals, electric, and plumbing,” Feidt notes. And the star of the show? The designer doesn’t hesitate: “The windows.” “We doubled the views of the sky and lake by adding a butterfly roof. The pendant-shaped windows on the sides of the butterfly extension stream-in morning and afternoon light we never had before. The effect is dramatic. They’re the ‘wow factor’ we were looking for.”

When an architect responds to his or her personal requirements, the choice of building materials can be interesting. For Feidt, there was no question about who he would cast as the lead for the project’s star attraction. “Marvin is my go-to supplier for windows and doors. We were able to use their standard-size units as a costsavings measure without compromising the aesthetics we were after. They make a really high-quality window and door system. And the price is competitive,” Feidt explains. Feidt anticipated the project would net a far more livable, comfortable home, with the lake providing an even higher level of visual drama and splendor. What was humbling was the way it now helps promote his practice to the regional marketplace. “The house was selected for a tour of architect-designed homes in the Twin Cities. The tour attracted twice what the organizers anticipated,” Feidt says. “It’s also been selected for a couple of local awards. The exposure has really increased the visibility of the practice and generated some very good leads.” It’s a bonus that should yield dividends for many years to come.

Some might wonder if the surge in window exposure creates comfort control problems inside. To the contrary, notes Feidt. “The awning windows are motorized. They’re left open in the summer. They draw the air in from lake so we seldom run the air conditioning. If it rains, a moisture-detection strip automatically closes them. Even with the expansive sliding doors (two assemblies – 16 foot and eight foot), the house passed two blower tests at twice the tightness code prescribes.”

Fiction Factory Mork-Ulns Completes Builds Prototype For California Ski Cahlet “Groundbreaking” Coated In Black Tar Cardboard House Amsterdam collective Fiction Factory has developed a modular building system of cardboard components, which can be assembled in just one day to form houses or offices (+ slideshow). Named Wikkelhouse, which translates from Dutch as Wrap House, the completed prototype comprises a series of interlocking cardboard segments that each weigh 500 kilograms. Each of these tubular components is 1.2 metres deep, and can be connected and disconnected to extend or reduce the length of the building. They also make it easily transportable. Each section is made from 24 layers of cardboard. These layers are wrapped around a house-shaped mould to achieve a rounded gabled form, before being bonded together with “eco-friendly” superglue to create a robust and insulating shell. “Wikkelhouse is what you get when an everyday material finds a groundbreaking purpose,” said Fiction Factory, a group of artists that has previously worked together to design interiors, fair booths and furniture. “Using cardboard as its main building material, Wikkelhouse is a cutting-edge sustainable house with a beautiful design and exceptional constructive strength.” The cardboard is protected from weather by a waterproof but breathable film and finished with wooden cladding boards to create a weatherproof enclosure. As the structure does not require a foundation, it can be built on a chosen site in just one day. Slot-in sections include a kitchen, shower and bathroom, and there are options for glazed or opaque facades.

This northern California cabin by Mork-Ulnes Architects is clad in tar-coated timber and sits atop a concrete plinth – measures that both help protect the structure from heavy snowfall. Encompassing 17,500 square feet (1,625 square meters), the five-bedroom cabin is located on Donner Summit near a major ski resort. It sits on a gentle slope, on a site with an elevation of 6,800 feet (2,070 metres). The cabin’s name, Troll Hus, refers to Norse mythology and Scandinavian folklore, in which trolls are said to dwell in remote mountains. The project was commissioned by a retired couple as a vacation home for their three children and grandchildren – all of whom are impassioned skiers. “Tucked away in the mountains and nestled into a high alpine forest, the design responds to the owners’ desire for a Modernist, rather secluded refuge with a constant visual reference to nature,” said Mork-Ulnes Architects, which has offices in San Francisco and Oslo. The home is clad in planks of solid timber coated in black tar, a traditional Norwegian technique that was used on stave churches in northern Europe during the Medieval period. The tar coating helps protect the home from weather and insects, and its dark colour enables the home to blend with its natural surroundings. “The distinctive black hue of the house helps it recede among the tree trunks of this wooded site,” said firm founder Casper Mork-Ulnes. The design was driven by the extreme environmental conditions of the site, which can become snowbound during the winter. Its footprint was kept as compact as possible.

Winners In Beautiful House Contest Include Marble Walls And Underground Rooms live in, will be also devoid of all the things that are unnecessary,” he added, “a house that is not trying to follow passing fashion, but rather strives to create clear and solid presence in the landscape by using very simple means.” A Place to Be by students Mateusz Ploszaj-Mazurek and Natalia Okolus comprises three timber-clad volumes overlooking a lake The second concept by students Mateusz Ploszaj-Mazurek and Natalia Okolus comprises three timber-clad volumes connected by a long semi-submerged volume with a glass front and terrace facing a lake.

Three fantasy house plans have been selected as the winners of the Design a Beautiful House competition: a marble-clad mansion, a subterranean lakeside dwelling and a linear property with faceted bays. The three concepts tied for first place in the ideas competition, which was organised by planning and design consultancy Barton Willmore and attracted over 660 entries. The brief asked entrants to devise a home for a family on a 91-hectare site in Hertfordshire, England, to meet an undefined definition of beauty. “The competition potentially ignites an array of discussions that highlight a global snapshot of ideas of ‘beauty’ and the ‘home’,” said Barton Willmore. The competition winners were selected by a jury including MVRDV partner Fokke Moerel, Neil Porter of London firm Gustafson Porter and Mick Finch, who is course leader at the London art and design school Central St Martins. The proposal reinterprets an old-fashioned mansion and focuses on function. The first design, Modern Mansion by Polish architect Maciej Grelewicz, is a simple block covered in sheets of white marble.

The jury praised the flexibility of the space within A Place to Be, which provides core communal areas below ground, as well as more separate quarters.What is a Beautiful House by French architects Sebastien Nuttens, Francois Derréal and Delphine Alibert comprises a long block.

SketchUp 2016 has arrived!

SketchUp 2016 has recently launched and with this release we’re integrating Trimble Connect directly into SketchUp.

When you reference a file from any of these services (.skp or otherwise), LayOut will notify you when an update is available for your ‘web reference.’

As a refresher, Connect is Trimble’s platform for storing, syncing, referencing, sharing, and collaborating on design/build projects. Sign up for a free account, then start uploading .skp, .pdf, .dxf, .ifc. files. With this integration, we’re packaging the current Trimble Connect Extension into the installer.

Say goodbye to missing references when different people are working on the same .layout document within a cloud sync folder that also contains the referenced files.

The TC integration is accessible from the File menu, and will allow users to upload, pull down, and update SKP’s from Trimble Connect project folders. As you’re modelling you can even pull in and update reference SketchUp models as if they were locally hosted components. Learn more about Trimble Connect... In SketchUp 2016, a context click on a component gives you the opportunity to reload (or swap out) a new component directly from 3D Warehouse. This action will reload every instance of that component in your model (similar to the same action in the Components Browser), so it’s a helpful method for working with proxy models. And if your component was downloaded from 3D Warehouse, you can also use the context-click to quickly access its 3DWH details page. With this release, LayOut’s reference objects are now web friendly. That means your LayOut projects can reference and update files that are stored and synced with services like Dropbox, Google Drive, and Trimble Connect Sync.

08

We’re proud to announce our first step towards an extension ecosystem for LayOut. Using this new API, developers can now create and customize .layout files from SketchUp models. Practically, this means that other applications can import or export the *.layout file format using the C API. (This includes creating a .layout file from SketchUp.). We have several sample scripts for developers to try out at release, along with a blog post where they can learn more. Learning and utilising SketchUp’s inference engine makes for fast and precise modelling. In this release, we’ve oiled that engine to provide slicker inferencing and locking across the board. This improvement is actually an entire set of smart tweaks we’ve made to inferencing and locking. You can download SketchUp Pro 2016 for free on a 30 day trial. After this time, the software will revert to SketchUp Make. Elmtec is the distribution partner for SketchUp in the UK. Contact us for more information on 01844 263750 or visit www.elmtec.co.uk/sketchup.


SketchUp 2016 is here!

Connected, refreshed and best of all....still SketchUp.

SketchUp, Connected Reference, sync, comment, report, and share: SketchUp 2016 is more connected than ever to the projects, information, and people you work with.

Simple, intuitive, just right Every day, we obsess over making SketchUp seamless and efficient. Here’s what our obsession yielded in SketchUp 2016. • • • •

CAD & BIM May 2016

New Approaches to BIM and Collaboration From its offices in The Boathouse in Putney, West London, bpr architects has focused its practice on family values since being founded by current director Paul BeatyPownall’s parents in 1975. He and fellow director Graham Wilson took over in 1994 and maintain a culture that he describes as a “family of architects all working toward the same goal.” But constraints from the recession and government mandates forced them to consider new ways of doing business.

S

purred by the requirement that all public sector designs be delivered with BIM Level 2 (the collaborative 3D environment comes with data separated by discipline) by 2016, bpr shifted from CAD-based work for their numerous university and rail projects. At the time, Beaty-Pownall tried to see how the firm could make the switch entirely to BIM, replicating every last detail of his drawings with Vectorworks® software’s 3D tools. “I wanted to prove that it was doable and then set about encouraging everybody in the office to switch over to 3D tools on all projects,” Beaty-Pownall says. With that shift — combined with a team downsized by the recession — the firm needed to be more collaborative than ever before, ultimately leading to the 2014 decision to turn the company into an employee-owned enterprise. “I think there is a really good relationship between the employee-owned business and the approach you need to be a successful member of a team that’s working collaboratively on BIM,” Beaty-Pownall says. “To work effectively in BIM, you need to be open and honest, willing to share and not be protective about information. In an employeeowned business, there is very little that becomes confidential because everybody is a part of that company. Likewise in BIM, people have to trust each other because you’re all using the same data,” Beaty-Pownall says. The firm’s transition to BIM and a new business structure overlapped as team members took on new responsibilities and found new ways to engage both with their designs and one another. Even as design meetings and ideas started to more efficiently flow, it was hard for the team to leave behind programs like SketchUp, which they had become experts at using. But the team members were won over by the additional tools in Vectorworks software, which have helped them explore even more appealing possibilities with BIM. “To me, the most important tool that Vectorworks Architect has to offer and that can really make a project shine is the Space Object tool,” Beaty-Pownall says. “When I’m promoting BIM to clients that are skeptical, one of the questions I get asked is how I work with an existing building,” Beaty-

Pownall says. “You get your 2D plan, you get your Space Object tool, you draw around every room and then you populate the data fields with information that tells you everything you need to know.” For bpr, this functionality provides clients with poignant data such as floor loading, ventilation and natural light throughout a building’s lifetime. It’s vital information that owners will want to know for long-term management or repurposing. Additional capabilities for renderings and remote access through Renderworks® software and the Vectorworks Nomad App have also encouraged new ways of collaborating with clients. The Renderworks add-on creates various visualizations of designs, from highly stylized photorealistic images to animations. “We initially purchased just four licenses of Renderworks,” Beaty-Pownall says. “It didn’t take us long to realize we needed it for everyone. It’s a

fantastically useful tool to present models to our clients.” The Vectorworks Nomad App even facilitates renderings on the go by enabling designers to share designs with clients on a smartphone or tablet. Viewers can fly around the form and shape of a building model that has been loaded into the cloud for retrieval on a smart device. Beaty-Pownall added, “Even informally, literally while having lunch with a client, you get your phone out and ask, ‘Well, what do you think of this?’” These tools, bpr’s new business model and the use of BIM have come together for new projects that include Premiere Hotel at Industrial Yards, West Hampstead Station and a model station for the Department of Transport — all projects for which the new tools and Beaty-Pownall’s attitude of “we’re all in this together” have paid off.

L

ate last year housing minister Brandon Lewis issued a call for more innovation in housebuilding. “We need to move to a system where homes are built in weeks, if not days,” he said. The industry is innovating to do exactly that, as VISION, the two-day event taking place on 7 and 8 June at Olympia London, will demonstrate. Its Offsite and Modular Construction seminar stream showcases some of the top projects, technologies and initiatives aimed at delivering homes and other building types. Cross laminated timber (CLT) has been growing in popularity for some time, along with the height of the buildings being designed with it. The world’s tallest pure CLT building looks set to be Regal Homes’ apartment development in Dalston Lane, in Hackney, east London, designed by architect Waugh Thistleton and currently on site. Meanwhile in Bergen, Norway, a 14-storey glulam and CLT hybrid apartment building is under construction, while Finland is home to an eight storey-high

CLT apartment block. Anssi Lassila, director and founder of architect OOPEAA, will be talking about the lessons from the Finnish project, called Puukuokka, on 7 June at VISION. Of course, innovation is not only being applied to the delivery of homes. On the second day of the conference, Alex Abbey, partner with architect Cullinan Studio, will outline how prefabrication was applied in the design of the Holy Cross Primary School in Swindon, working with timber frame manufacturer Stewart Milne to develop a kit of structural timber cassettes and laminated timber columns and beams. The resulting school was efficient to build, meets the constrained cost parameters of current school funding regimes, provides flexible teaching space and is an elegant design. One of the key attractions of using timber in buildings is

its sustainability, and factory production methods in general promise a range of environmental benefits, as Dr Robert Hairstans, head of the Centre for Offsite Construction and Innovative Structures at Edinburgh Napier University, will explain in his presentation on 8 June. VISION combines a 2 day seminar programme, exhibition and networking events. Other highlights include: •

Country Mansion Goes Green with Polypipe Underfloor Heating A rural mansion in Surrey has had Polypipe Underfloor Heating installed throughout as part of it’s large scale, high specification build.

Renewable energy specialists, Worcester Renewable Energy Ltd., specified Polypipe, the UK’s leading manufacturer of above and below ground drainage, plastic plumbing and underfloor heating systems, to provide Burrows Lea Farmhouse with environmentally friendly heating in conjunction with a ground source heat pump. Polypipe’s Red Floor Plate Solid Floor System was specified for the ground floor of the farmhouse due to its ability to provide an ambient temperature throughout the property and its environmental credentials over alternative heating systems. Although the systems works perfectly with combi boilers, in this instance it was used in conjunction with ground and air source heat pumps, which extract warmth from the air around the property or the earth in the garden. This process further reduces the amount of energy boilers need to use, consequently improving energy rating performance and reducing CO2 emissions. Water based underfloor heating continues these environmental benefits by operating at an average water temperature of 50 degrees Celsius, rather than the 80 degrees used by traditional radiators, and therefore requires a lower temperature rise from the boiler. This means that to produce an equivalent heat output, the water can be stored at a much lower temperature, lowering household energy costs. As under floor heating systems become more sophisticated, their cost efficiency is increasing. As previously set out, the system runs at lower temperatures to radiator systems, while individual rooms can be heated to the desired temperatures without needing to switch on the heating in every room. The first floor of the mansion benefitted from Polypipe’s OverlayTM system, which is the ideal solution for heat pump installations and first floor rooms as it can be laid directly on top of existing floors offering much higher outputs at the low flow temperatures delivered by heat pumps than other systems that are installed beneath floors. At only

18mm in depth, the OverlayTM systems allows underfloor heating to be installed in projects where other underfloor systems would require expensive excavation or where the existing floor would be raised to an unacceptable level. Darren Stockall at Worcester Renewable Energy, said: “When specifying the system for Burrows Lea Farmhouse, we needed to consider aesthetics as well as performance. The property has been designed and built to visually impress and wall mounted radiators would not be in keeping with the feel of the space. We also needed a system that would work alongside a ground source heat pump, for practical and environmental reasons. Polypipe’s underfloor heating systems were the obvious choice.” Dave Foster, Heating Manager at Polypipe, added: “The owners of Burrows Lea Farmhouse needed a heating system that was cost effective, discreet and environmentally friendly. Working alongside Worcester Renewable Energy we were able to fulfil all their heating needs, providing the property with the perfect heating solution.”

Are you getting too many hot sticky nights? Before you answer that look at the two pictures below:

T

he baffling, aspect of this phenomenon is that the two materials can have very similar u-values - so that in steady-state conditions, heat applied at a constant rate over a period of time, to the external face of both materials, there is an equally constant flow from the inside surfaces of diminished heat. What is different about the caravan and stone house examples is that the heating is not steady-state: real life heating from the sun varies throughout the day. This variability is known as ‘periodic heat flow’, and, fortunately for the purposes of building design, it is almost entirely predictable. It doesn’t take much to rapidly heat a building through a lightweight structure such as a roof, pitched roofs are efficient solar collectors and large in area compared to the internal volume of the internal space. Vaulted ceilings and rooms in the roof are often the hottest areas within a building. Timber roofs are lightweight with low thermal storage capacity; heat from the sun will quickly transfer into space below, just like in the caravan. So we end up with bedrooms and living spaces that get too hot and create uncomfortable sleeping conditions, by the time we find this out it’s normally too late. The key here is density because mass acts as a heat buffer, this leads to a phase shift, the time span between the highest external temperature and the highest internal temperature. The aim is to delay the heat transfer through the fabric of the building so that high external temperatures only reach the internal side when it is already cooler outside. Many insulation products are chosen for their u-value and thickness materials such as PIR and mineral wool have broadly similar densities and heat capacities so their decrement capabilities are relatively insignificant.

24

In the caravan, as soon as the outside cladding starts to warm up, heat output is recorded within minutes on the inside face as heat quickly transfers through the aluminium / lightweight insulation composite; as the face of the stone wall heats up the heat progresses much more slowly from the outside to the inside. A proven answer to the problem is to use wood fibreboard insulation materials with high levels of diffusivity, now performance can be more closely mapped to traditional masonry construction thus moderating internal temperature through the materials. The effect of material choice is illustrated in the graphs below.

Loft Insulation In the UK, there are 23 million houses with properties that also have loft spaces. According to Government figures, around 15 million of the houses have insulation of over 100mm (though often nowhere near the current building regulations of 270mm) but there seem to be no figures for insulation levels of non-domestic properties. For many of the buildings without adequate insulation, access and storage requirements are cited as the reason, because the owners want to be able to access M&E equipment or they want to use the loft as a space for storage. Well, at least we have over half of the country’s properties with properly working insulation… except, alas, no we don’t. That’s because research by the National Physical Laboratory and Carbon Trust shows that in 80% of insulated properties, the insulation isn’t working, and that the reduction in thermal resistance from what is expected is at least 50%. Why is this? The issue is one of compression: for mineral wool-type insulation, it needs to retain its full depth to work properly. Ask the insulation manufacturers how performance is diminished if the insulation is squashed and they will simply tell you that it’s an abuse of the product to squash it, which is correct. But, in both the residential and nonresidential sectors, insulation is regularly squashed. Carbon Trust sponsored the biggest ever survey of loft users, with 6,000

26

responses, and the results are eye-watering: • 82% use their loft for storage • 78% say the loft is greater than half full • 76% say loft storage is important or essential • 65% have fully or partially boarded their loft at joist height (typically squashing or removing the insulation down to 75 or 100mm) • only 26% knew that squashing loft insulation was bad for it. In effect, 82% of lofts users have compromised their insulation, and only 26% of users knew this was reducing its effectiveness. This isn’t only the private sector that is to blame; the

survey also included social housing tenants, and 32% of those said they were using their loft too, even if the tenancy agreement forbad this.

Add this up over the whole UK and this is a massive in-use reduction, equivalent to switching on one whole power station. After millions of pounds of CERT and CESP funding for insulation over the past few years, this is depressing reading.

What is the effect on the U-value from compressed insulation? Tests by the National Physical Laboratory on the market- The easiest solution Is to prevent loft leading mineral wool insulation found: insulation from being compressed by the use of a raised deck above it. One such • Compression from 270mm to 100mm system, the LoftZone StoreFloor raised (4” joist height) results in a reduction of loft deck, provides safe storage and access the thermal resistance of 50% space without compressing the insulation. You wouldn’t put external wall insulation • Compression from 270mm to 75mm (3” on to a building and not protect it with a joist height) results in a reduction of the render. So why fit loft insulation without thermal resistance of 61%. protection too?

Recticel’s innovative cavity wall insulation gains LABC certification Recticel Insulation’s Eurowall + is now an LABC Registered Detail.

E

urowall +, the full fill cavity wall product from PIR manufacturer Recticel Insulation, has been certified as a Local Authority Building Control (LABC) Registered Detail. Registered Detail status ensures that products and systems are accepted by building control departments across England, Scotland and Wales, increasing confidence for inspectors on site when approving the use of new or innovative construction techniques. Approval involves looking at product performance data and other third-party approvals such as BBA certificates, in order to prove compliance with building regulations and standards, and to ease the process of making submissions to building control for customers wanting to specify and use the product. The assessment started at a local level, with initial checking carried out by senior building control officers

28

at Stoke-on-Trent City Council. Approval was then signed off at a national level, ready for the Detail to be accepted by local authorities across the UK. Recticel development manager Peter Wilcox said:

“Eurowall + joins LABC’s library of rigorously checked systems and products, ready for use by architects, specifiers and contractors. We look forward to working with LABC again on other new and exciting product innovations.” Eurowall + is an LABC Registered Detail under certificate number EWW620. It is a full fill cavity wall insulation that changes the way a wall works, without changing the way contractors work. A nominal 10mm cavity behind the outer leaf leaves space for bricklayers to position bricks as normal, while the thermal performance of the wall is increased without widening the structure.

Microhome with moving walls addresses UK housing crisis Microhome QB3 – part of the University of Hertfordshire’s Cube Project - has debuted at the Edinburgh International Science Festival. QB3 has just 18m2 of floor area, but uses two moving walls to convert different parts of the space between lounge, bedroom, kitchen and bathroom.

QB3 provides a flexible and modern home for a single person or a couple and is optimised for energy use. It uses two heat pumps (for heating and hot water), heat-recovery ventilation, LED lighting and TV, A++-rated appliances, triple-glazing and excellent insulation. There is also the option of a green roof, with solar photovoltaic panels, that would make QB3 energy neutral over a typical year. Dr Mike Page, Director of the Cube Project, said: “Low-energy microhomes like QB3 can play a crucial role in providing affordable housing. There are plenty of small, underused spaces, especially in cities, in which these fun, practical buildings can play a useful role in addressing housing needs”. Microhome QB3 can be viewed at the Edinburgh International Science Festival, The Mound Precinct, Edinburgh EH2 2EL.

Windhager UK’s new technology biomass boilers Windhager UK’s new technology biomass boilers have been installed to provide the heating and hot water to Scotland’s oldest hotel. The Salutation Hotel in Perth, one of seven hotels in the Strathmore Group, dates back to 1699 and is now Scotland’s longest established hotel. The hotel joined the group in 1991 and has undergone some great refurbishments, including the installation of a 360kW Windhager biomass heating system, to make it the hotel it is today. Two 180kW Windhager BioWIN Excel Kaskade systems were installed by Newcastle-based installers, Green Guru NE, to provide heating and hot water to the 84-bedroom hotel. This replaced the hotel’s gas-fuelled system to offer a greener solution

32

to heating whilst significantly reducing its carbon footprint and energy costs. Gerry Hamill, Property Manager at the Strathmore Hotels Group commented, “Reputedly being the oldest and longest running hotel in Scotland, we are very pleased to see The Salutation Hotel is now efficiently operating using the newest form of renewable energy. The hotel has been refurbished and expanded to offer more rooms, which has increased the level of heat and hot water now required for the property. We were advised by the team at Green Guru NE that installing Windhager’s wood pellet

biomass boilers would not only provide a more economical solution to our heating, but would help to reduce our carbon emissions whilst providing a high level of comfortable heat for our guests.” He continued, “Since the installation we have been very impressed with the reliability and performance of the boilers and we have noticed a great improvement in the heating supplied. The installation by Green Guru NE was very efficient and did not disrupt the running of the hotel. We would happily recommend Windhager’s biomass boilers to any other hotels or property owners that are looking to boost their


May 2016 Heating

green credentials and improve their heating systems.” The installation reflects the Strathmore Group’s commitment to sustainability, which has won the hotels in the group the Green Business Tourism – Silver and Bronze Awards yearly since 2006. In 2015, the group replaced the heating systems in all of its hotels with an installation of 36 Windhager BioWIN Excel wood pellet boilers across the seven hotels. The group saw many benefits in converting its heating systems to biomass, including the significant reduction in carbon emissions, minimised energy costs and the ability to source the biomass fuel from the UK which ensures a secure and stable fuel supply. The installation of two 180kW Kaskade systems, each comprising

three Windhager 60kW BioWIN Excel automatically-fed wood pellet boilers, was completed within the footprint of the hotel to fuel the heating and hot water systems to the rooms. This cascaded format of the boilers is especially beneficial to the hotel as it provides a reliable supply of energy with automatic back up support from the other two boilers should one need to be shut down for maintenance. Particularly suitable for a wide range of commercial property applications, the Kaskade heating system allows large and variable outputs to be achieved and can be controlled using the Windhager Kaskade operating system. The wide modulating output range ensures the boilers consistently provide their maximum efficiencies depending on the requirements of each installation.

Available up to 300kW, a Windhager Kaskade system can be created to offer any output required using the company’s proven BioWIN Excel high performance wood pellet boilers. These boilers operate a fully-automated feed system so that minimal user interaction is required. The BioWIN Excel incorporates a self-cleaning burner bowl and a large ash box that only requires emptying up to three times a year so that maintenance is truly kept to a minimum. Windhager has also developed a patented BioWIN ignition device that is not a wearing part and is also maintenance-free for the safest and most efficient boiler operation possible.

Case Study May 2016

FLOOR SLIP TESTING FOR CURRENT LEGISLATION – CE MARKING Ensuring floors are slip safe is now a major requirement on all construction projects. Whilst expectations are still the same in terms of aesthetics and functionality the increased onus on responsibility for safety at the construction phase makes an anti-slip system an option to meet all requirements when selecting tiles for new floors, ensuring they meet all safety recommendations prior to installation. The Construction Products Regulation (CPR) (305/2011/EU) requires any permanent product to be assessed against a harmonised standard which in the case of flooring is the pendulum slip test.

PENDULUM TEST EXPLAINED The pendulum slip test has been recognised by the Health and Safety Executive as a reliable and robust test to provide accurate analysis on the slip potential of all types of flooring. This test can be used to portray bare foot and shod foot dependent on the area the tile is to be used. The pendulum slip test is the subject of BS 7976: Parts 1-3 – To determine the slip resistance of pedestrian surfaces and BS – EN14231 Natural stone test methods. The Pendulum Slip Test is based on a swinging, imitation heel sweeping over a set area of flooring in a controlled manner. The slipperiness of the flooring has a direct and measurable effect on the pendulum test value (PTV) given. After a series of results in a number of directions using the pendulum - the average result is given. Using the table below the PTV is then assessed. 0—24 High potential for slip 25—35 Moderate potential for slip 36+ Low potential for slip

SAMPLE TILE TESTING If you have a tile which has been specified but need to be sure that it will be fit for purpose before laying we offer an in-house pendulum testing service in our purpose built laboratory – whereby the sample tile can be tested in its ‘as found’ condition. Our comprehensive test will provide clear results in the dry and wet conditions and provide you with concise results and any recommendations.

ANTI-SLIP TREATMENT Our individually developed anti-slip treatment micro-etches the surface of the tile which works to accentuate the natural peaks and troughs of the stone. The aim of the treatment is to achieve the maximum grip with the minimum impact to the aesthetics of the floor. Varying characteristics of different floors, (porosity, density etc.) combined with the operational use mean that every requirement is different therefore adjustments can be made to the treatment to meet the standards for the intended use. If your sample tile does not meet the required PTV – we could help. We offer a treating service where we can then apply our tailored treatment and retest. Results will then be sent before and after treatment showing the difference that can be made. Testing starts from just £75 plus VAT.

TILES ALREADY LAID – BUT SHOWING SLIP RESISTANCE ISSUES? If you have a floor which has been laid but is now showing signs that it may not reach slip resistance requirements for the area and there are slip concerns – we can apply our anti-slip treatment to laid floors to bring up slip resistance to the required level. Once treated we will supply full report and slip test results, along with a certificate of conformity which provides you with evidence should due diligence be brought into question. 01206 826788 sales@sliptech.co.uk www.sliptech.co.uk

4D CONTRACT FLOORING GETS CREATIVE WITH CARPET PLANKS! National flooring contractor 4D Contract Flooring is the latest company to opt for the ‘planked look’ in carpet, after selecting Array and Broadrib planks from Heckmondwike FB’s Creative range. Managing Director at 4D Contract Flooring, Rob Kilner selected Array in black and Broadrib in graphite to complement 4D Contract Flooring’s corporate colours. The project was part of an office refurbishment at the company’s Southern headquarters in Buckinghamshire, with the carpet installed throughout the general office space, breakout and meeting areas. Rob Kilner, Managing Director at 4D Contract Flooring, said: “We chose the planked look as we were looking to create a modern and stylish appearance in our office. Because we install lots of Heckmondwike FB’s carpet, we know that it is durable and performs well and will provide a striking appearance for many years to come.” David Farrow, Area Sales Manager for Heckmondwike FB, said: “Array and Broadrib carpet tiles offer a designer feel especially when they are chosen in a planked style. This makes them a great choice for office and reception areas, combining the inspirational design of the Array range with the durability and practical benefits of fibre bonded carpet.” Heckmondwike FB’s Array carpet tiles feature a mid-width rib design with a charcoal background, enhanced with a subtle linear pattern. This stylish design co-ordinates perfectly with the company’s Broadrib carpet tiles in a complementary solid shade to provide a stunning effect and endless creative design possibilities. And it’s not just the Array range which is available as planks. The planked tile is an option across many of Heckmondwike FB’s ranges. These carpet tiles replicate the size and shape of contemporary planked flooring through the comfort of fibre bonded carpet, and enable specifiers, designers and flooring contractors to create individual designs for a wide variety of commercial flooring applications. Being able to add this element of high design creates a fusion between the floor and furniture. Like all Heckmondwike’s products, Array carpet tiles can be cut on-site without the risk of fraying and this allows individual flooring designs to be created and installed with ease. Heckmondwike FB’s carpet tiles are British-made and provide outstanding performance, as well as being backed by a 10 year limited wear warranty. They offer antistatic and anti-slip performance, excellent acoustic properties to help reduce noise levels, as well as offering excellent thermal performance. Sample cards for Array and Broadrib are available on request by calling 01924 406161 or visiting the website www.heckmondwike-fb.co.uk For more information about 4D Contract Flooring, visit the website: www.4dcontractflooring.com

RAISING THE NEW SCOTLAND

May 2016

ALARM AT YARD BUILDING An advanced wireless alarm system from Bull Products is playing a key part in the multi-million pound redevelopment of the Curtis Green Building, the new home for Scotland Yard on the Victoria Embankment, London. The 1937 building designed by architect William Curtis Green is a neo-classical design and the move to this building is part of the Met’s drive to reduce operating costs. In the refurbishment, architects AHMM have designed an extension to the rear of the building, a glazed entrance pavilion, roof top pavilion and an ‘iconic blue line beacon’ to the open plan offices at the top of the building. The famous rotating sign is also moving to the new building and re-named Scotland Yard. Main contractors Royal BAM Group have been working on the project for nearly two years and the completion date is Autumn 2016. The refurbishment involved some demolition and soft strip of the interior and in the early stages of the project, the alarms fitted were smaller sounder units. It wasn’t long before a more sophisticated and reliable alarm system was required to ensure the health and safety of the construction workforce. The Cygnus wireless alarm system from Bull Products was selected for the job, and a total of 30 fire alarms and first aid alerts are installed across all the floors, each wirelessly linked to two main Cygnus control units, one in the extension building and one in the security section of the site office. Andy Lee, Site Manager for BAM is very impressed with the performance of the alarm system, “This Cygnus system has been

immensely valuable to us, covering such a large area of the building. The system’s dual functionality for both fire and first aid has been an important element in its choice.” He continued, “Crucially, these alarms can be heard over the sound of demolition work and so as the project developed the Cygnus wireless system became a necessity.” Bull Products’ Cygnus wireless alarm system can link as many as 480 alarm and detector units in different zones on a construction site, and individual units can be fire alarm call points, first aid alerts, combined call point and smoke detectors or heat detectors. Intended purely for use on construction sites, the CE marked Cygnus system has been specifically designed for use in dense concrete and steel structured buildings and areas where there are many other radio frequencies in operation, and so particular attention has been given to achieving an impressive connection range. Where there are multiple sites within range of each other, the Cygnus system has been designed to operate on different site addresses in order to keep each system separate and free from interference. A major feature of the Cygnus system is the optional control panel which provides a very sophisticated capability with an event log function

which records any events such as an alarm activation, low battery warning, and signal faults, all of which can be viewed if necessary in the history folder held on the panel. The system also has the ability to test all units and has an evacuate function which will act as a call point to the rest of the alarm units. Each unit in the system can provide the panel with information at regular intervals. This explicit information confirms the unit is still present and what the battery status of each device is. Known as the ‘heart beat’ this message is monitored by the control panel where fitted and if the ‘heart beat’ is not heard for several intervals, the control panel logs a full status for that unit. A PIR option is now available on any of the modules which can detect an intruder and alert off-site personnel for added safety protection. Bull Products offers a full oneyear guarantee on all Cygnus devices and provides high levels of technical, on-site and after-sales service support in addition to its standard maintenance contracts. Further information on the Cygnus wireless alarm system is available from Bull Products on 0844 669 1111, by emailing info@bullproducts.co.uk or by visiting the company’s website at www.bullproducts.co.uk

Architecturally-ambitious glass roof transforms SOAS University of London 22 April 2016 – London: SOAS University of London and GRAHAM Construction have unveiled the glass roof on the university’s £17.3 million redevelopment of the North Block of its iconic Senate House. The project will transform an underused courtyard to provide a multi-purpose space through the addition of an architecturally-ambitious glass roofed-atrium constructed between the school’s existing Grade II listed buildings. This freestanding structure will create an inspiring interior for both students and staff on a single unified campus. The additional 1,000 sq m will be home to the new Student Hub which includes student finance, careers and enterprise services with a multi-purpose breakout area and café. The roof structure, which took six months to complete, is among the most technically demanding components of the scheme due to the intricate nature of the glass installation. Each panel needed to be lowered into place by a tonne telescopic crane. It called on GRAHAM’s extensive experience of scheduling complex projects to ensure all the elements from the subcontractors to the site were ready and on-site activities co-ordinated efficiently. The roof itself will allow in natural light and ventilation that will help keep running costs and energy consumption low. Rainwater will be collected from the roof, stored and reused within the building; a system that has only been retrofitted into a handful of Grade II listed buildings. GRAHAM Construction’s London office director Rob Joyce said: “The striking glass roofed-atrium creates a bright and inspirational space for collaborative working and socialising for students and staff alike. Our scope of work also included refurbishing five floors of existing accommodation to provide a mixture of teaching facilities, breakout areas and academic offices, as well as multi-purpose open-plan space. We understand the importance of creating an environment which is welcoming and creates spaces to encourage different ways of leaning, while providing integral resources for the university.” The project is due to complete in June this year.

Roof slates from Welsh Slate feature on a refurbished building at the heart of the regeneration of Kings Cross. Welsh Slate helps a landmark gymnasium flex some new muscles

S

ome 6,400 natural slates from Welsh Slate have helped restore to its former glory the roof of the first purpose-built gym in England, albeit now as a designer restaurant. More than 600m2 of Welsh Slate’s 500mm x 300mm Penrhyn Heather Blue Countygrade slates have been used on the main and clerestory roofs and flank roofs of the dormer windows of the Grade ll listed German Gymnasium a landmark in the King’s Cross regeneration masterplan. They were specified by architects Allies and Morrison to return the roof to its former appearance after the original Welsh Slate roof (which is an important early example of the use of laminated timber to enable broad spans) was removed and the building was left with only a bituminous felt covering across the structure. They also match the slate roofs of the adjacent St Pancras Station and Great Northern Hotels. The new roof over trusses up to 20m wide was installed over four winter/spring months by Attleys Roofing who were reliant on multiple, small deliveries due to the tight site, lack of storage and range of materials required to bring the roof up to today’s standards – insulation, vapour control layer, counter battens, felt, battens and Welsh slates. After a 17-month rebuild the renovated building was officially opened to the public by restaurant group D&D London in November (2015).

50

Originally designed by Edward Gruning and built in the 1860s, the German Gymnasium was influential in the development of athletics in Britain. The building cost £6,000 and was funded solely by the German community in London with the intention of promoting strength-based gymnastics for men and women. The National Olympian Association held the indoor events of the first Olympic Games there in 1866 and they continued there annually until the White City games in 1908. After the First World War the building was taken over by the Great Northern Railway and converted to offices, being subdivided into cellular offices, with first floor, staircase and internal partitions inserted to divide up the overall single volume. It remained in the ownership of the railway operators under various acronyms until it was drawn into the overall masterplan for the redevelopment of King’s Cross. The earlier demolition of the buildings around it and the emerging context have allowed the public realm surrounding it to become a more dynamic space, the building becoming both a way-finding landmark and a destination in its own right. Allies and Morrison were commissioned by developer Argent to restore and repair the fabric of the building to a shell and core finish to enable subsequent fit out by one of three shortlisted restaurant operators. Conran and Partners established the

restaurant concept design and completed the fit-out which includes a new steel mezzanine and staircases. Andrew Rixson of Allies and Morrison said: “The design of the roof is complicated by the increased depth of the new roof build-up in that the additional thickness of the roof sets the new slate tiles above the level of the brickwork details of the existing gable parapets. “To resolve this, our design approach separates the slates from the brickwork by introducing hidden gutters, valleys and leadwork detailing around the perimeters of the roof. These details are adapted into various different forms due to the variety of conditions found within the existing roof and the deformation of the timber roof structure over time but reconcile the precisely constructed new roof elements with the unevenness of the Victorian brickwork.” He added: “Welsh Slate provided technical advice throughout the design phase through telephone consultation and product literature. The slates could be used in a consistent tile size with even colour and their fixings hidden by the overlapping of each tile. We were also able to resolve design problems using the integrated and unobtrusive service penetrations, which are pleasing architecturally and from a conservation perspective, by avoiding the need for a proprietary vent pipe protruding above the pitch of the roof.” Tina Attley of Attleys Roofing said: “The Welsh Slate has provided the aesthetics required by the client and the architect and at the same time has kept it in keeping with the area. Everyone is really pleased with the roof.”

Natratex Cotswold Specialist Hard Landscaping Material

B

ituchem’s specialist hard landscaping material, Natratex Cotswold, can play a key role in the design of new housing developments, offering an attractive solution for pathways, driveways and roads. Based on the colour of Cotswold stone, which is growing in popularity for modern-build houses, Natratex is great for creating a matching landscape to the surrounding buildings. As the company’s flagship product, Bituchem has seen many applications of the materials to new housing development sites, where the product has proved to be a striking alternative to standard black tarmac to add to the aesthetics of the site. Natratex Cotswold is as durable as it is attractive and has been specially designed to withstand regular pedestrian and light vehicular use. The material uses a range of naturally occurring coloured aggregates and is bound using a clear binder to ensure the finish is durable and does not fade in appearance or performance. With minimal maintenance requirements, landscapes using the material will not need to be closed for lengthy periods of time, which would cause unnecessary disruption or inconvenience to residents or local businesses.

56

Natratex’s hard-wearing qualities also make it a particularly safe

material for applications in residential areas where is it is regularly used by pedestrians, and in particular, children and elderly residents. The material is resistant to cracks and potholes and therefore ensures a constant, flat and smooth surface that will not create a trip hazard. The non-abrasive and monolithic nature of the top layer also means minimal damage will be caused should somebody fall. Bituchem takes into consideration the many factors of the house building process including budget and time restraints and has developed Natratex as a low-cost, time-saving solution for every landscaping requirement. Unlike other aesthetic hard landscaping materials on the market, Natratex is very cost-effective yet still offers the same high performance and durability as alternative products. The material is also very simple to apply and takes very little time as it does not require on-site mixing or gluing and can be laid using conventional equipment. Natratex can be applied for new construction, overlays or regeneration projects to make it suitable for both new-build and redevelopment schemes.

Flood Resilience with Energy Benefits The adoption of flood resilience measures is increasing as a key measure to address the growing problem of storm water disposal. Just days ago Amendment 110 was tabled by Baroness Kate Parminter in the House of Lords which would remove the automatic right to connect surface water to the public sewer system, compelling developers to integrate Sustainable Urban Drainage Systems (SuDS) to address the growing problem of storm water disposal. The implementation of SuDS provides a proven and low cost solution to reduce the £1.3 - £2.2 billion of flood damage each year in England. Aquaflow ThermaPave™, manufactured by Formpave, is an ingenious Sustainable Urban Drainage System capable of harvesting surface rainwater, which can also be used as the energy source for ground Source Heat Pumps (GSHPs) to provide energy efficient heating and cooling for buildings, effectively turning paved areas such as car parks into energy centres. This system provides a highly effective method of flood resilience, is cheaper to maintain than conventional drainage, and represents good ecological and economic reasons for the adoption of SuDS. When compared to the separate costs of a SuDS installation and a GSHP installation, this now multipurpose facility, provides both these functions at greatly decreased overall cost. Incorporating rainwater harvesting, adding yet another dimension and opportunity for on-site cost savings. In fact, the water from the Aquaflow Thermapave SuDS+ design is pH neutral as a result of the filtration properties of Inbitex Geotextile incorporated in the construction, which also eliminates the need for costly “petrol interceptors” required in many other types of systems. A SuDS installation incorporating GSHP ground coils, must account for both civil engineering requirements and energy extraction for the heat pump. The Thermapave design not only caters for these mixed needs, but enhances the civil engineering aspects and heat pump performance without increasing overall costs. From an energy perspective the permeable paving blocks themselves have high thermal absorption properties further enhancing the heat pump energy yield. On top of the heating, water bill savings and flood defence benefits Aquaflow Thermapave brings, the Government provides attractive financial inducements through the Renewable Heat Incentive (RHI) which pays companies using ground source heating systems a renewable heat tariff which is guaranteed for 20 years and index linked to inflation.

Charcon Introduces New Concrete Paving to Range Charcon, the commercial hard landscaping division of Aggregate Industries, has introduced three new concrete pavers to its portfolio: UrbanPave premium flag paving, Vianova Maxx large element textured paving and Monksbridge rumbled effect block paving. UrbanPave UrbanPave has been designed to provide a premium landscaped surface for ultra-contemporary public realm schemes, such as town centres and prominent pedestrianised areas. The premium flag paving has a light texture and comes in a choice of three made-to-order colour options – Light Grey, Mid Grey and Dark Grey. Four paver sizes cater for the increasing trend towards large aspect paving and provide flexibility in laying patterns. Vianova Maxx Vianova Maxx is a large element textured paver that combines a modern feel with high quality performance. Available in two sizes and three made-to-order shades – Light Grey, Dark Grey and Anthracite Charcoal – Vianova Maxx can be used to create contemporary laying schemes, and complements other Charcon products including Andover Textured, Natural Granite and Eco Countryside Kerb. Monksbridge Monksbridge block paving is a viable alternative to traditional rumbled products and is suitable for pedestrian areas where vehicle overrun is likely. It is ideal for creating a traditionally-styled, naturally cobbled look. Available as mixed packs of four sizes in three colour options – Cinder, Croft and Royale.

Mike Davies, Specifications and Major Projects Manager for Aggregate Industries, comments: “The introduction of three new products to the Charcon range demonstrates our continued investment and ongoing commitment to delivering the very best solutions for any commercial hard landscaping project. The new products set the standard for performance, quality, durability and aesthetic appeal.”

Recycled Plastic in the Construction Industry Human creativity and innovation is seen at its best when it comes to recycling plastic, but we can do much more in the construction industry and gain a competitive advantage from it.

L

ocal authorities are meeting their recycling targets but have avoided recycling polystyrene as their targets are set by weight and generally polystyrene is light but takes up a lot of space.

In January 2010 three Bolton brothers joined forces to conquer the recycled plastics market in Lancashire and now employ 15 people with demand growing at 30% a year. The real source of the company’s growth comes from the impact of the product on recurring costs. Spending on labour and materials for maintenance and replacement of wooden or metal products is eliminated because with recycled plastic there is none, just the one cost of initial installation. Kedel’s plastic extrusion process produces synthetic or plastic wood from old CD cases and it has a remarkable resemblance to the wooden alternatives. CD cases just happen to be made from polystyrene that local authorities are throwing into landfill or incinerating. Kedel’s Plastic Wood won Best Recycled Product in 2015 at the National Recycling Awards. Produced in a wide variety of profiles and colours it can be used for tongue and groove back gates and beech hut cladding, brightly coloured fence pales for schools, long life decking, open v-cladding, picnic tables, benches and building accessories, such as pediments, rafter tails, gallows brackets and porch posts. A Golf Club in Bolton has just replaced all their cedar cladding with plastic wood to keep the club looking great for years to come. According to Club Council Member, Steve Gore, “It’s a great investment that’s good for the club because it’s maintenance free now for decades and will pay for itself.” Contacts: sales@kedel.co.uk or call 01282861325 www.kedeltrade.co.uk

Thousands of walkers and tourists have already taken a walk on the wild side and loved it. With an ever growing number of travel reviews and blogs singing its praises the Paiva Walkway, constructed from around 3,000 cubic metres of timber treated with Celcure ® supplied by Koppers Performance Chemicals, snakes along the left bank of the River Paiva providing visitors with a safe and secure way of navigating through the impressive flora, fauna, geology and archaeology of the area. The route extends from the river beach of Areinho to the beach at Espiunca, taking in the Vau beach along the way in a region recognised by UNESCO as a Geological

66

Heritage of Humanity. Work started on the project in May 2014 with the final touches applied in June 2015 before the inauguration ceremony. The total cost of the project was €1.9 million with 85% of the funding coming from the European Union. Municipal funding made up the shortfall with running and maintenance costs expected to be around €40,000 annually. Ivo Brandao, Press Officer for the Arouca Geopark, explained: “The President of the municipality came up with the idea with local government technicians involved in the planning and checking process. “The project was delivered by a private corporation under our strict guidelines with glued, laminated timber supplied by CARMO. “We expect somewhere between 700,000 and one million people to use the walkway every year and initial feedback has been very positive. We are already impressed with the positive impact that this walkway has had all around the country. We have received enquiries from lots of tourists looking for a specific kind of experience with close contact to nature. This kind of natural tourism is proving to be very popular all around the world.” Caroline Lauro, Marketing Manager at CARMO, added: “The contract for the path not only included supply of the treated timber but also the assembly, maintenance and inspection.” “It has so many twists and bends and relies on many creative and technical solutions to attach the path to the rocky scarps. Some parts of the walkway were inaccessible by foot which meant we had to call in climbers to help with the assembly.”

Matthew Hempson Business Development Director at Koppers Performance Chemicals said: “We are seeing a growing interest in these sorts of naturebased walkways. They offer an excellent way of experiencing nature up close and personal. “We have just been involved with a similar project in the Cuilcagh Mountain Park in County Fermanagh in Northern Ireland with a 1.6 km boardwalk treated with MicroPro. The 8km Paiva Walkway is, however, on a wholly different scale. “Celcurised Timber is the industry- recognised term for timber that has been preserved with a Koppers Performance Chemicals Celcure® brand preservative system, based on an effective combination of copper and organic co-biocides. In use for more than 25 years in locations throughout Europe, North America, Australia and Japan, Celcure ® preservatives have a proven track record of performance. “Pressure treated to force the preservative deep into the wood structure; it provides protection where it matters. Timber treated using this system is suitable for Use Classes UC1, UC2, UC3 and UC4, including fencing, timber decking, landscaping timbers and construction timbers. “Celcurised Timber will initially have a green appearance that highlights the natural variations of the wood. This will weather to an attractive natural honey brown colour before finally fading to a driftwood grey after long- term exposure to the sun. Celcure® treated wood products can be painted or stained to match any outdoor colour scheme. “In the case of the Paiva Walkway, the timber was treated

at Carmo Wood’s treatment facility in Portugal.” The final word belongs to one of the many walkers who are helping to turn this boardwalk into a well-worn path. “Even though we didn’t manage the full walk this time around, we were all most impressed and will return for more,” wrote English tourist Julie Fox in her blog at juliedawnfox.com. “The scenery is gorgeous and although the walkway stands out in its newness, it will soon fade in colour and blend into the background. “With the Celcure preservative, this wonderful area of natural beauty, on Europe’s periphery, will now be accessible for visitors for generations to come.” A real walk on the wild side, Portuguese style. www.kopperspc.eu

Charcon Delivers a Colossal 4,200 Tonnes of Hard Landscaping Materials to Swansea University’s £450m Bay Campus

paving in Rustic colour was used for the meandering streetscape. Reminiscent of traditional setts, all three sizes were incorporated to create eye-catching designs. The exterior of the great hall was paved with StoneMaster in Medium Grey (600m x 450mm) from Charcon’s Life range, made from a fine stone mix of up to 50% reclaimed or recycled materials, yet resulting in a granite effect without the expense of using natural stone. Alongside the paving, 2,000m² of Eco Countryside Classic Kerbs and edging was also supplied to help add visual appeal to the functional roadside edging.

Charcon, the commercial hard landscaping division of Aggregate Industries, has demonstrated its superb product and logistical capabilities by supplying a colossal 4,200 tonnes of hard landscaping materials to Swansea Bay Campus, all within a tight time frame of just six months. The ambitious £450m project by the University of Swansea has doubled the size of its academic and research facilities, establishing Swansea as a dual-campus university destination. Situated at Neath, Port Talbot on the approach into Swansea, the campus has been developed on St Modwen’s 65-acre former BP Transit site, transforming the bay’s industrial landscape into a modern, hi-tech district that rivals the world’s top 21st century universities.

Charcon consulted with contractor Vinci Construction at an early stage of the project. The architecture of the university buildings already present featured both traditional

and modern elements. This was a key driver in the choice of paving products and shades to make sure the landscaping would complement these buildings. Charcon therefore recommended its Andover Textured range for the contemporary public spaces and squares. Offering a premium quality block paving product at an affordable price, the Silver Fleck and Silver Grey shades were combined for maximum visual appeal in 300mm x 200mm blocks, with a total of 10,295m² of Andover Textured being specified. To contrast, 8,280m² of traditionalstyle Woburn Rumbled cobble

John Sheehan, project manager at Vinci Construction, comments: “Bay Campus has been an immense project that had to be delivered within an incredibly tight timeframe. By working closely with Charcon from the outset, we have benefitted from their technical abilities, as well as the welcome reassurance of efficient deliveries and products of the highest quality. “At Vinci, we are immeasurably proud of having delivered phase one so successfully, and we would like to extend our thanks to all involved at Charcon in helping to achieve this.” Mike Davies, Specification and Major Projects Manager at Aggregate Industries, said: “Our team worked very hard and liaised closely with Vinci throughout the project to guarantee correct and timely delivery of all orders placed. Overall, we made 188 deliveries of quality-assured products whilst fulfilling additional product requirements along the way.” Charcon will continue to supply products for the second phase of works which is already underway and scheduled to end in 2020, ready for the University’s centenary.
