G ove ’ s water y fate

You have to feel sorry for Michael Gove, Secretary of State for Levelling Up, Housing and Communities Actually, you don’t – but it’s difficult, for once, not to have sympathy for the Government in its efforts to cut through the mess created by the regulations concerning ‘nutrient neutrality’ – those that try to ensure that development doesn’t increase phosphate and nitrate levels in watercourses beyond current levels

Worries in the EU about nutrient neutrality first surfaced in the Netherlands in 2018 in an ECJ court case which decided development should not have significantly adverse effects upon areas of conservation concern So far, so far good

However, Natural England picked up on these concerns and, broadly ignoring the ‘significant’ aspects of the ECJ ruling, started issuing formal guidance to local planning authorities about these pollution risks – whether significant or not – and effectively stymieing the building of tens of thousands of homes

The sector has been howling about these ‘gold plated’ regulations, more stringent than the ‘significant impact’ rule envisaged by the EU, ever since, as the Government itself has acknowledged that the effect of new development on nutrient neutrality is “negligible”

To quote the Home Builders Federation, Defra’s figures suggest that 60-80% of phosphorus entering rivers comes from a failure of water companies to treat wastewater effectively This wastewater comes from many sources including the hundreds of thousands of existing homes, plus from transport and commercial operations Industry has long argued that the additional contribution of new homes each year is negligible in comparison to existing loads

More water efficient new homes could help reduce the amount of waste water occupants moving from older homes would generate Defra also acknowledges that “agriculture and wastewater are together the biggest sources of nutrient pollution in the water environment”

The penny finally dropped for the Government and Gove who, with some fanfare, announced that they would modify the Levelling Up and Regeneration Bill with the effect of relaxing the rules at the end of August

Well: if a week in politics is a long time, then two weeks is a fortnight – and that’s how long it took for Gove’s grand plans to meet a watery fate at the hands of the House of Lords, where a cross-party coalition led a rebellion in the Lords to defeat the Government in the vote Gove, of course, blamed Labour yet failed to note the role of Tory Peers such as the Duke of Wellington and Lord Blencathra (ooh, deputy chair of Natural England wouldn’t you know) in his defeat.

Unfortunately for Gove, and the sector, the amendment was introduced at the Report stage of the bill and, having been scuppered by the Lords, it will require new legislation to tackle this topic again.

Given the other current travails of the Government, and Gove – the housing crisis being merely one – it is difficult to see the Parliamentary time being found to bring this legislation to the Commons, let alone get it past those pesky Lords, and so the (so far and current) 74 LPAs subject to Natural England’s negative guidance on nutrient neutrality won’t be building much new anytime soon

Superglass raises £2,000 for CRASH

Employees from Superglass have raised over £2,000 for CRASH by taking part in a sporting fundraiser Nine employees from the Stirling-based insulation firm took part in the world’s largest 5k inflatable obstacle race at the Hopetoun Estate, near Queensferry

Established in 1996, CRASH is the UK construction industry charity, helping homelessness charities and hospices with vital construction projects such as roof maintenence, extension and refurbishment building and accessibility infrastructure

Superglass has worked alongside the charity since January 2022 , providing resources and financial aid as part of a long-term partnership

Last winter, the company teamed up with community charity Start Up Stirling to provide support packs to ensure those who are struggling with energy costs remain warm. Included items were insulated clothing, flasks and hot water-bottles, alongside advice on energy efficiency.

Lords scupper water rules relaxation

The House of Lords has rejected the Government’s proposed amendment to the Levelling Up and Regeneration Bill (LURB), permitting development where nutrient neutrality has been cited as an issue It has been estimated that 145,000 new homes could be built by 2030 if nutrient neutrality regulations are loosened

The government announced plans to relax these rules through an amendment to the LURB, currently going through the Lords Because of the late stage at which the Government introduced the change, it now cannot try again in the Commons Ministers would need to bring the proposal forward in a new bill

A cross-party coalition led a rebellion in the Lords to defeat the Government in the vote This is despite Natural England’s own admission that “the risk from new homes is very small” and Government’s own research finding agricultural run-off and the inaction of water companies to maintain infrastructure to be the main causes of the nutrient neutrality issue.

The Home Builders Federation says that maintaining restrictions in affected areas “will do nothing to improve the shocking state of our rivers, polluted by agricultural run-off and the failings of water companies, but will exacerbate our housing crisis still further.

“With growing waiting lists, a generation unable to buy, local economies damaged, and jobs lost, the mishandling of this issue is a national disgrace ”

It also said it was “a damning indictment that after four years politicians have completely failed to find a solution Despite the occupants of new homes making a negligible contribution to the issue, and housebuilders giving water companies over £1 billion in the past three years alone, the impasse goes on ”

David Churchill, partner at Carter Jonas, comments: “With an amendment to

LURB now out of the question and the only route to a solution supposedly being new primary legislation (to be announced in the King's Speech in November) we face many more years of delay – I anticipate a doubling of the backlog

“What is very disappointing is that immediate solutions have been overlooked For example, the use of levies and CPO to deliver new wetlands as a form of mitigation – as has been used successfully elsewhere

“It would have the added benefits of removing the poor-quality agricultural land which requires more fertilizer from agricultural use and delivering more biodiversity. We don’t lack the land, or the will of the landowners to address the problem, but something so vast cannot be achieved on a piecemeal basis ”

Research shows that housebuilders have given water companies over £1bn in the past three years to ensure infrastructure is in place to facilitate new homes – something they have failed to deliver This comes as the Office for Environmental Protection admits that the Government and regulators have broken the law by not keeping sewage companies in check

Despite this housebuilder funding, and new homes making a negligible contribution to the problem, a moratorium remains in place in 74 local authority areas While housebuilding has been blocked by Natural England, Defra’s figures suggest that 60-80% of phosphorus entering rivers comes from a failure of water companies to effectively treat wastewater.

No grumbles at Harron from the Old Goats

Legacy, improving on last year’s £36,000 at yet another sold-out event

For the third consecutive year, Harron Homes has sponsored the Old Goats Grumble festival in Denby, Derbyshire, right by the housebuilder’s Shipley Lakeside development With the help of Harron Homes’ £3,000 contribution, the music festival raised £40,000 for cancer charity Lauren’s

Lauren’s Legacy was established in memory of Lauren Elliot, the inspiration behind the Old Goats Grumble and attendee for many years, and who died from cancer in June 2019

By raising funds via donations and events such as the Old Goats Grumble festival, Lauren’s Legacy aims to fulfil the

wishes of teenagers and young adults going through cancer treatment; whether through family holidays, concert tickets or seats at major sporting events.

Lauren’s Legacy has now acquired a deluxe holiday home at Ashbourne Heights Holiday Park in the Peak District, allowing families going through cancer treatment a chance to have a free stay for long weekends.

Water water everywhere – so don’t even think about building near it

Resi starts show faint revival

Glenigan’s September

2023 edition of its Construction Review suggests that the resi sector is showing weak signs of recovery: against a backdrop of bad news for the rest of the construction industry Residential starts-on-site increased 6% during the three months to the end of August – albeit to stand 11% lower than a year ago. Private housing was up 14% against the preceding three-month period, although still nearly 10% less when compared to 2022

While not grounds for cheer as such, the Q3 figures are in contrast to the Q2 Home Builders Federation’s last Housing Pipeline Report – also based on statistics from Glenigan – which showed the number of planning permissions granted across England for new build houses continuing to fall, maintaining the downward trend of the past two years

At 2,456, the number of projects granted planning permission during Q2 of 2023 was the lowest since the Housing Pipeline Report began recording in 2006. Approval was granted for 62,681 homes during the second quarter, dropping 16% on the previous

Cleantech company Vector Homes has unveiled its prototype flatpack home built using sustainable and advanced materials after undergoing testing at a g research facility in Manchester Vector is working with Energy House 2 0, part of the University of Salford, to develop its new rapid-build housing system.

The prototype is a low-carbon, onebedroom bungalow measuring 40m2 which has been constructed using recycled materials, including steel and plastics, as well as advanced materials such as graphene

Vector is designing affordable, energy efficient homes with features including low-embodied carbon materials, infra-red heating, solar cells, breathable mould-resistant plaster and render, as well as embedded technology to provide smart environmental controls that efficiently measure and control the temperature, humidity and air quality in each room

quarter and 13% as compared to the same period a year ago. Other than the quarter affected by Covid-19, Q2 2020, this is the fewest permissioned homes in a quarter since 2015

Despite upbeat news around overall planning approvals, and bright spots in residential and civils performance, the rest of the September review paints a depressing picture of decline across almost every sector

Commenting on the review, Glenigan’s economic director, Allan Willen says: “Whilst recent editions of the Review have made for sobering reading, an impressive uptick in detailed planning approvals on last year should be welcomed It’s encouraging to see growth in individual sector verticals, with civils starts up 3% and a tentative recovery in residential starts ”

Stocksigns has raised £15,000 for The Children’s Trust, thanks to an intrepid team of nine Stocksigns employees taking on a two-day trek through the rocky valleys of the Paradise National Park in eastern Slovakia, via narrow ladders, precarious walkways and sheer-sided cliffs On the second day the team ascended to 8,250 feet above sea level on a 13 hour round trip to reach the top of Mount Rysy – a peak that lies on the Polish side of the border and holds the title of the country’s highest mountain

Spitfire celebrates 1,000th home milestone

Spitfire Homes has handed over the keys to its 1,000th home, a landmark for the Midlands-based builder Spitfire was first established more than a decade ago and this milestone signifies further growth for the business – with 1,000 homes now completed across 51 developments, the πbuilder is setting its sights on even bigger aspirations

structures, the panels used in the construction of a Vector home have improved tensile strength, a greatlyreduced flame spread and increased UV resistance Vector has worked with the University of Manchester’s Graphene Engineering Innovation Centre to develop ways of incorporating the material into its housing systems

Launched earlier this year, the £16m Energy House 2 0, at the University of Salford’s Peel Park Campus, is globally unique and is helping to drive innovation in the housing sector already, through work with housebuilders and manufacturer Saint-Gobain

Recent developments to help drive these plans includes Daventry (542 homes), Radcliffe-on-Trent (280 homes) and Moreton-in-Marsh (250 homes), providing a significant development pipeline for the future.

Ben Leather, managing director of Spitfire comments: “It’s been a fantastic decade for Spitfire and delivering our 1,000th home is a great achievement. However, this is just the beginning – the next ten years will look very different as we deliver our plans for growth, building Spitfire to become the Midlands’ premier homebuilder ”

Vector reveals sustainable prototype at Energy House 2.0

The development sits within the grounds of a 650-acre private state, which is home to the Grade I listed Gothic-style mansion, Hensol Castle, an exclusive wedding and conference venue at The Vale Resort The Vale Resort is known for its two championship golf and a spa The resort also provides training facilities used by the Welsh national rugby team, the Welsh national football team and Cardiff City Football Club.

Inspired Villages has exchanged contracts on its newest site in Farnham Royal, Buckinghamshire It plans to transform the 12-acre site into a community for more than 200 over-65s and provide 177 apartments, cottages and bungalows. Alongside homes, the community will also include a village centre with a spa, wellbeing facilities, a bistro restaurant and lounges

Inspired is also due to open its ninth operational village, Millfield Green, the UK’s first Net Zero Carbon (regulated energy) community, this autumn Millfield Green is the blueprint for all future developments, including Farnham Royal, as the business strives to deliver its ambition of being Net Zero carbon (regulated energy) by 2030

Royal contract is Inspired

At Millfield Green 100% of its homes have been optimised using ground source heat pumps and solar panels and the infrastructure is installed to facilitate electric car charging throughout The development also uses high‐quality insulation, ventilation and high‐performance triple‐glazed windows, resulting in using only clean, REGO-backed energy, as opposed to fossil fuels.

The latest figures from the Builders Merchant Building Index (BMBI), published in August, show that quarter-onquarter sales climbed +7.6% in Q2 2023 compared to January to March 2023. Growth came from stronger volumes (+11.3%) as prices were -3.3% lower. With four less trading days in the most recent period, like-for-like sales were +14.8% higher.

Quarter-on-quarter, six of the twelve categories had higher value sales, with seasonal category landscaping (+47 3%) out in front, followed by heavy building materials (+9 0%) Timber and joinery products (+2 1%) grew more slowly than merchants overall, while plumbing, heating and electrical (-12 2%) and workwear and safetywear (-12 7%) were the weakest categories.

Q2 2023 was down -4 1% on Q2 2022 as volumes fell -13 5% with prices up +10.9%. There was no difference in trading days Value sales increased in nine of the 12 categories in Q2 2023 compared to the previous year with renewables and water saving (+44 4%) significantly ahead of the rest Decorating (+12 3%); plumbing, heating and electrical (+9 1%) and ironmongery (+6 1%) also increased, and heavy building materials (+0 5%) showed marginal value gain Timber and joinery products (-16.3%) and landscaping (-12.4%) both saw significant declines

Total value sales for June were +2 6% ahead of the same month in 2022, helped by two extra trading days this year Volume sales in June 2023 fell -5 4% year-on-year and prices rose +8 4%, but two of the categories had their highestever monthly value sales: decorating and heavy building materials, with decorating up +18.3% on the previous June.

June 2023 total merchant sales were +4 6% higher than May 2023 Growth was driven by a combination of higher volumes (+7 2%) and June having two more trading days Prices were -2 5% lower in June than in May Like-for-like sales were down -5 0% Nine categories had higher value sales in June with Ironmongery (+7 1%) doing best, followed by landscaping (6 9%), kitchens and bathrooms, and tools (both +5 9%)

Paul Edworthy, commercial lead: builders merchant group; Dulux Trade and BMBI’s expert for paint commented: “The rolling quarterly figures provide a fair measure of performance as both Q2 2022 and Q2 2023 have exactly the same number of working days (60 in total)

“On this basis, decorative trade paint litreage was 3% higher in the last 3 months with woodcare up 8%. For paint, this was the best quarterly outcome since January 2023 while for woodcare it was easily the best improvement for over two years For the last month alone, trade paint sales increased 8% in June - the second consecutive monthly improvement In woodcare, trade woodcare was 67% higher

“Year-to-date, volume was 1% higher than in the first six months of 2022, while the MAT figure shows that over the last 12 months there has been a 0 6% increase compared to the same period a year earlier These metrics are indicating a more positive market as we enter the second half (H2) and with exterior being supressed in H1 2022 due to poor weather there is still room to grow

“In terms of sales by sector, trade paint sales to builders’ merchants were down 9% in Q2 2023 compared to Q2 2022 There are some signs that raw material prices are coming down which should inspire new work starts and, with that, bring more volume to the builders’ merchant sector.”

Simon Coop, senior director, Lichfields, reports on how viability is the key to ensuring that new housing can be delivered.

Recently published data has revealed that the UK housebuilding activity has fallen by the fastest rate since the start of the COVID-19 pandemic. This decline has been exacerbated by rising mortgage rates and a subdued market but there is a deep concern that the changes to the NPPF that were proposed in the Government’s consultation document result in even deeper reductions

At the heart of the matter relating to the housing crisis are questions relating to how many new homes do we need, where are they required and how can we make sure they can be delivered Central to that final point is the issue of development viability

At its most basic level, viability relates to the relative balance between the value generated by a development and the costs associated with its delivery If a scheme is not viable then, generally

speaking, it is unlikely to come forward The issue of development viability has long been an important consideration in the planning system with the focus tending to have been on whether specific policy requirements (for example, relating to affordable housing provision of Section 106 contributions) can be sustained

Planning policy in England and Wales now seeks to front-load all consideration of development viability so that it is given a much greater emphasis at strategic plan preparation stage By placing viability at the heart of the plan-making process, the assumption is that developments that accord with the strategic plan will be viable It would be for an applicant to demonstrate why the viability of their development is compromised because of changes in circumstances since the plan was prepared and adopted

At a time of continued high inflation –with the cost of building materials still

rising, albeit now at a slower rate – house prices stagnating or even falling in many places, and policy expectations increasing, the viability challenge has never been so acute Coupled with the deepening housing crisis, the need to get any consideration of viability right is greater than ever

In considering viability, planning policy advocates the use of standardised inputs. This was considered in detail by Dove J in the case of R (Holborn Studios) v London Borough of Hackney (2020) Paragraph 63 of that judgment noted that the PPG “makes clear the preparation of a viability assessment ‘is not usually specific to that developer and thereby need not contain commercially sensitive data’ ” In the absence of any guidance on the inputs that should be applied, Lichfields’ Fine Margins research provides clarity on the issue

From Gove with LURB

In its recent revisions to the NPPF, the Government committed to ‘build enough of the right homes in the right places with the right infrastructure’ Unfortunately it has set out to achieve this by blaming the failure to do so on developers – specifically ‘bad developers’ who ‘play the planning system’

Michael Gove also tabled an amendment to the Levelling Up & Regeneration Bill (LURB) in a similar vein The amendment would require developers to report on the build-out rates of residential planning permissions and also enable councils to take account of applicants’ records of delivery in deciding whether to approve or refuse future applications

This should be considered in the light of the furore over housing targets: the fact that housing targets have all but ceased to exist in the recent re-writing of planning policy Not only are housing targets effectively over, but it is hard to imagine how housing need can be met in current circumstances

It’s not clear how one reconciles the need for developers to report on

housing delivery while at the same time doing away with any requirement for councils to meet any defined target. More to the point though, the abolition of housing targets is of seismic consequence compared to the tremor of a developer’s annual report on delivery It’s a shot through the heart, and whomever is to blame, the abolition of the targets gives LURB a bad name.

Nevertheless, what would the need to report on delivery and its consequences for future applications mean for developers?

I will skip past the nuisance impact of this, and the question of how overstretched local planning authorities will resource the administration of this new reporting task Perhaps they can re-use some of the left-over red tape that will be lying around to wrap this process up in Developers’ main concern will be that planning permissions can quickly change from being a benefit they have earned to a millstone around their necks Securing planning permission will mean they enter into a new contract, of sorts, being to ‘deliver or else’ The ‘else’ being they risk being blacklisted on future applications And not necessarily just in an authority they may have failed to deliver in There seems

Grant Leggett, executive director, Boyer, considers how the Government’s aim to penalise developers for land banking gives the Levelling Up & Regeneration Bill a bad name.

no limitation in the amendment as to whether a planning authority may examine a developer’s record nationally, and it may be that developers are required to submit their records in support of applications as a validation requirement

It is also not clear what justification developers will be able to rely on in explaining away non-delivery of a permission. Developments sometimes just go wrong, despite the best endeavours of developers They would at least need comfort that misfortune in one instance would not mean they are fettered in future

Ultimately the amendment will mean developers will either make fewer applications, or refuse to sign Section 106 agreements unless they are absolutely certain they can be delivered

This will unduly affect smaller developers who are already most disadvantaged Like it or not, a lot of smaller developers’ business is based on selling on land with permission to other parties who have the capability to build And building is riskier than ever at the moment due to uncertainties around build costs and supply chains, and the looming

threat of interest rate hikes and decreasing residential property values

The amendment also seems to undermine the use of Section 73 to amend planning permissions in order to optimise them or to make them viable

The more flexible use of Section 73 to more readily amend planning permissions was one of the Government’s tools to kick-start development after the last recession The amendment seems to create a Catch-22 whereby if a developer applies to amend an unimplemented (unviable) permission a council could refuse it on the basis it hasn’t been delivered Protracted discussions over scheme viability will therefore no doubt abound prior to Section 106 agreements being signed, delaying applications further, and affordable housing will be the main casualty

Developers would of course welcome some carrot along with what seems like a weighty stick Exploring a form of incentive for quick delivery might be a better option rather than a punishment for non-delivery This might be a fast-track for developers that have a positive record of delivery, or a ratcheted infrastructure levy that encourages development more quickly

But one senses any hint of mercy to developers would be seized upon by those that oppose development and be torn up LURB is increasingly becoming a NIMBY charter that will tragically stifle delivery

Designing for water quality

The publication of the Plan for Water by the Department for Environment, Food & Rural Affairs (Defra) in April this year signalled the Government’s intention to tackle water pollution Clearly, one of the ways to do this is by using a well-designed SuDS management train which considers both water quantity and quality, deploying SuDS components that are appropriate for the levels and types of pollution present in the surface water

This is recognised in the Plan, with reference to Schedule 3 of the Flood and Water Management Act 2010, which will make adoption of SuDS for new developments mandatory The Government had announced in January 2023 that Schedule 3 would be finally implemented in England, as it already has been in Wales, possibly coming into force in 2024, subject to consultation

SuDS are often thought of as a way to manage water quantity by reducing flows into sewers and hence reducing activation of combined sewer overflows (CSOs) which discharge raw sewage into water bodies. SuDS should also be designed to manage water quality directly by removing pollutants where it is carried in surface water The CIRIA SuDS Manual, C753, prescribes a risk-based approach, setting out the expected levels of pollution for different development types and then defining how natural and engineered SuDS elements, used as a

single entity or together, can be used to remove the various forms of pollution.

When it comes to engineered SuDS components, designers and specifiers can turn to British Water, the body which represents water and wastewater companies Having published a code of practice in 2016 and a ‘how to’ guide for manufactured stormwater treatment devices in 2022, the organisation is now hosting a list on its website of engineered SuDS components which have had their pollution treatment information verified by an independent third party expert The ADS StormTech system, with its Isolator Row – a built-in water quality treatment device – has recently been added to British Water’s list of assessed surface water treatment devices

Types of pollution

There are four main types of pollutant that can be found in stormwater run-off: sediments, metals, hydrocarbons and nutrients. Sediments, often referred to in pollution mitigation as total suspended solids (TSS), is particulate matter including particles of soil. Metals and metal compounds can be dissolved in run-off or attached to silts and sediments in the water Copper and zinc, which are most commonly found in surface water in the UK, can damage plants in higher concentrations

Hydrocarbon pollution comes with runoff from roads, car parks and areas where

Now there are verified mitigation indices for engineered SuDS components says Stuart Crisp, UK manager at Advanced Drainage Systems (ADS).

machines operate and are maintained, due to oil and fuel spills, tyre and brake wear. Changing climate means that rainfall events are further apart but more intense, leading to higher concentrations of pollutants, as they build up for longer before being washed away

Nutrient pollution, usually nitrogen or phosphorous based, can come from sources such as run-off from agricultural land where fertiliser has been used or combined sewer outfalls, where wastewater and surface water are discharged into bodies of water They can lead to algal blooms, which reduces oxygen in the water and can negatively impact on aquatic habitats

Mitigation indices

The SuDS Manual’s method for dealing with water pollution risks starts by determining pollution hazard indices for the area under consideration. In Table 26 2, the manual provides pollution hazard indices for a range of land uses and for three types of pollution: TSS, metals and hydrocarbons So, for example, for a busy public car park such as a supermarket or hospital, the index for TSS is 0 7, for metals is 0 6 and for hydrocarbons 0 7

The next step is to identify a SuDS

treatment train that can provide the necessary mitigation indices, either a single stage or using a combination of components The manual has a table for that too, Table 26 3 However, this table only provides indices for natural SuDS components, stating that proprietary treatment systems must demonstrate that they can address each of the contaminant types to acceptable levels.

For engineered components, British Water’s two documents – Code of Practice for the Assessment of Manufactured Treatment Devices Designed to Treat Surface Run-off and ‘how to’ guide, Applying The CIRIA SuDS Manual (C753) Simple Index Approach To Proprietary/Manufactured Stormwater Treatment Devices – provide a methodology to calculate mitigation indices for TSS, metals and hydrocarbons

The mitigation indices for ADS

StormTech’s Isolator Row are 0.8 for TSS, 0 6 for metals and 0 7 for hydrocarbons = 0 7 This means that it meets the requirements for medium pollution hazard applications and the TSS requirements of high pollution hazard applications and can be used as a combined SuDS attenuation and water quality treatment system without the need for additional components within the treatment train

Small machines, big capability

Yanmar Compact Equipment is expanding its wheeled loader portfolio with the launch of a pair of mini machines: the V7 and V7-HW (Heavy Weight). The duo are the smallest wheeled loaders in Yanmar CE’s product range and are designed to keep ahead of the demands of construction, landscaping and rental applications.

The company claims the wheeled loaders will make life easier for operators in every way possible –starting with manoeuvrability With a total height less than 2 5m, a width of 1 85m (with bucket) and an overall length of just 5 238m, the V7 and V7-HW can easily fit inside a standard container – a transport friendliness that keeps under the 4m height limit dictated by the EU’s Weights and Dimensions Directive of 1996

The all-wheel drive V7 and V7-HW both have an electronically controlled drivetrain, and a top speed of just over 12mph; with just over 18mph max speed available as an option Customers can further customize their machines by choosing between a premium range of tyre brands and sizes, making the loaders well suited to any application, no matter how tough the terrain

Lower transport height

The new loaders are said to do away with exterior oscillation and instead feature a clever joint that combines articulation with oscillation, enabling the height of the machine to be lowered The units are also a half-tonne lighter than the next largest machines in the Yanmar range (weighing 4,250kg and 4,450kg respectively), making these light-footed ‘workers’ for customers landscaping on soft surfaces

Whether transporting materials, rehandling loading, lifting pallets, clearing or laying pipes – all can be tackled with a single machine, thanks to a hydraulic quick hitch that enables the operator to seamlessly swap between buckets, forks, sweepers, snow blowers to name but a few

The V7 and V7-HW have a bucket capacity of 0 7m3 and 0 8m3, respectively, and the V7-HW has a higher payload on forks (1,900kg) compared to the V7 (1,750kg) The V7 has a maximum tipping load of 3,000kg, while the V7-HW can tip 3,250kg

Rear visibility is good, thanks to the engine hood design and absence of a vertical exhaust pipe. Large mirrors and powerful work lights further aid safety and visibility, day or night Roof mounted glazing, meanwhile, helps make operators’ lives easier when dumping from height Controls fall easily to hand and ergonomics have been a priority in the design of the V7

Operators need not be concerned about downtime either; thanks to the loaders being fitted with a four-cylinder turbocharged diesel The engine is not only low emission, but also offers no scheduled maintenance on its DPF for an incredible 6,000 hours, catering to the long hours of those working in the construction sector

Electr ic mini

Designed to meet a growing demand for electric machines, compact equipment, such as mini excavators, has a higher tendency to work in cities and residential areas where it has proximity to other workers and so has a great advantage over diesel counterparts due to less noise and no emissions

Retractable tracks allow the new excavator to pass through narrow passages and entrances/exits, making it suitable for working in confined spaces or indoor applications. Once the excavator reaches the work area, the operator can expand the tracks for better stability and lifting capacity With its compact dimensions, the DX20ZE-7 is a good solution for companies working in sensitive areas where low noise or nighttime work is necessary

The mini-excavator is powered by an in-house-developed 20 4 kWh lithium-ion battery pack, with all the

electrical system and components on the machine optimised for work in harsh environments. A quick-charger system restores 80% of the battery power after only one hour and 20 minutes of charging, while the on-board charger restores the maximum charge after eight hours of charging

Telematics is standard on the DX20ZE-7 mini-excavator Operators and dealers can remotely monitor their machine’s health, location and productivity from an app or website Telematics can help owners: minimise equipment theft and allow for machine tracking; avoid unauthorized use of the machine; see when maintenance is due; customise alerts to a customer’s schedule; track oil pressure, operating temperature and more; and use data to train operators for maximum productivity

The DX20ZE-7 miniexcavator is the first massproduced electric-powered excavator manufactured by DEVELON. This two-tonne excavator combines lownoise and zero emissions with the features and performance enhancements that are found on the next-generation DX-7 Series family of mini-excavators.

The Future Homes Standard (FHS) has been looming on the horizon for over four years – long before the Covid pandemic, the Ukraine war and resulting fuel costs escalation, and last October’s disastrous mini Budget threw three substantial curve-balls at the housebuilding industry

While few of us question the need for our industry to take some responsibility for the climate crisis and do what we can to mitigate it, some are beginning to question whether there is a risk that the FHS could threaten the viability of new homes And ironically, new homes have the more impressive sustainability credentials than other sectors of the property industry

The FHS was first announced in 2019

More recently, the Future Homes Hub was commissioned to report on the subject and consequently Ready for Zero was published in February We are now awaiting the Government’s response, which will determine the implementation of the FHS

From 2025 the FHS will require that all new homes produce 75-80% less carbon emissions than homes built under the current Building Regulations

Reductions in carbon emissions will take place through improving heating and hot water systems and reducing heat

waste This will be achieved by replacing existing technologies with low-carbon alternatives, including building fabrics, other materials, insulation, glazing and heating technology (primarily air and ground source heat pumps)

As a step toward achieving this, the Government updated the current Building Regulations, specially Part F (Ventilation) and Part L (Conservation of Fuel and Power) These requirements have applied to UK homes since June 2022

In terms of addressing climate change and meeting net zero, I very much welcome the FHS However, it will have considerable consequences for housebuilders and its potential impact must be considered in some detail before the new requirement is rolled out

Housebuilding is facing a ‘perfect storm’ – as is demonstrated by last year’s output of new homes and the inevitability that housebuilding figures will fall again this year

Important considerations that will impact on viability include the availability of a materials and appliances (along with the skills to both fit and maintain them); who will pay for the increased costs, and the ability of the supply chain to adapt to new procedures

h ll h F Homes Standard mean for housebuilders, asks Tim Foreman, managing director of Land and New Homes, Leaders Romans Group (LRG)

As we have seen with the Building Safety Act and the legal sign-off needed for ensure the safety of cladding, the process of buying a home has been considerably compromised when an inadequate process requires solicitors to sign off non-existent cladding It is imperative that this anomaly is not replicated in the context of the FHS. But with a chain of professionals including planners, developers, contractors, surveyors, solicitors and agents, required to adapt their procedures to reflect these new regulations, there is huge potential for complication and delay.

We know that people choose new homes because they appeal to a sense of responsibility for the environment along with reduced energy costs But there is a limit to how much people will,

and can, pay for these benefits when purchasing a home. Inevitably part of the considerable cost will pass up the development chain, impacting both on development profits and land values We are already seeing considerable upheaval in the planning system and again, there is a limit to the price that can be paid.

The climate crisis is real and must be addressed But the country needs new homes. I do believe that most developers, and purchasers, welcome environmentally responsible new homes But if costs and complications are so great that new homes become unviable, the FHS will have resulted in fewer future-proofed homes being developed and exacerbate the issues that the industry currently faces

The UK Net Zero target needs heat pump installers that are up to the challenge, says Russell Dean, residential product group director, Mitsubishi Electric.

The decarbonisation of property is a particular challenge for the UK, with heating accounting for a third of all the country’s carbon emissions However, awareness of this issue is growing – and the government has pledged to reach 600,000 heat pump installations per year by 2028 to tackle this.

Russell Dean at the opening of the Harlow College Renewable Energy Training Centre

There is a problem with this though

The heat pump installer market is currently a fraction of what it actually needs to be Nesta, the charity, is predicting a shortfall of 27,000 installers needed to fit these heat pumps by 2028 This isn’t just an issue for the installer market – it has repercussions for the entire housing value chain, including property developers

So how do we address this disparity?

Decarbonising the UK’s homes with heat pumps will require a skilled installer base, and the industry – including developers – must support the upskilling and future-proofing of the next generation of engineers to fit heat pumps. By focusing efforts on securing the knowledge and expertise necessary to meet installation quotas, developments can decarbonise efficiently while heeding government restrictions

Pressure to make the switch

The drive for low-carbon heating is partly motivated by consumers becoming more eco-conscious, especially where heating is concerned In fact, recent research by Mitsubishi Electric and Ipsos shows that 41% of British consumers agree there should be a deadline for the decarbonisation of residential heating within the next decade Due to this,

developments offering consumers heating which aligns with their eco-conscious ideals are in demand.

New builds are also a heavy focus for the Government’s plan to reduce carbon emissions from home heating, and the installation of heat pumps will play a major role for homes built to the Future Homes Standard The target of reaching 600,000 heat pump installations per year by 2028 is another marker that the Government is more motivated than ever to unlock the benefits of low carbon heating technologies.

However, these ambitions from both consumers and Government can only be realised with a base of fully-trained heat pump installers – which the UK is currently lacking To hit the government’s goals, a tenfold increase in the number of installations is needed over the next five years This can be achieved by upskilling installers – from installing gas boilers to installing heat pumps. If we fail to do this, it could risk this target being missed in the future

Installers backing the low carbon transition

Although there is significant work to be done to close the current installer gap, there is evidence that installers are

interested in supporting the switch to low-carbon heating. In fact, over half (56%) of installers want to undertake heat pump installation training in the next 12 months.

Net Zero through training and funding

Investing in the green economy to meet Net Zero will bring new opportunities for businesses This can be from new

technology and creating tools to assist in the installation of heat pumps. For example, from the cylinders that accompany heat pumps – such as the pre-plumbed cylinders recently brought to market by Mitsubishi Electric – to support services

Additionally, investing in heat pump training is essential. Every gas boiler installer can train to install heat pumps Initiatives to motivate businesses to pilot heat pump training, while also offering modular qualifications for on-the-job training are important Equally vital is supporting engineers, plumbers and gas installers on how easily these courses can be accessed to ensuring widespread availability and inclusivity

The industry should also ensure tradespeople are knowledgeable on the overall benefits of heat pumps alongside the individual benefits of upskilling in this area This will allow installers to provide impartial, accurate advice to consumers looking to install heat pump technology in their homes

Final thoughts

The shortfall in the number of engineers needed to fit renewable heating technology – like air source heat pumps – is an easy fix as there is a future heat pump installer on every street, it’s just that they are installing fossil fuel boilers now. To meet the Government’s ambitious decarbonisation targets, this opportunity needs to be recognised Builders now have a clear perspective on the sustainable targets for their new developments The advancements in heat pump technology, controls and the support functions offered by the industry can make achieving these targets a realistic journey

Health and ef f iciency

Installing good insulation in housing stock is a crucial step towards Net Zero homes. Simon Storer, chief executive of the Insulation Manufacturers Association (IMA), reports.

As the drive to combat climate change intensifies, achieving Net Zero emissions will be essential in meeting this challenge Installing high quality insulation in residential buildings cannot be overstated as this plays a crucial role in creating energy-efficient homes, necessary for our Net Zero targets By focusing on performance, including carbon reduction and thermal conductivity, insulation will drive us towards a more sustainable future

Carbon reduction and insulation

The built environment accounts for a significant portion of greenhouse gas emissions, so reducing the carbon footprint of residential buildings will be essential for the journey to net zero Insulation materials such as PIR (polyisocyanurate) and PUR (polyurethane) can achieve exceptional thermal performance

which will help reduce the energy consumption and associated emissions

The low thermal conductivity for PIR and PUR insulation, allows for the installation of a thinner insulation layer whilst maintaining optimal insulation performance, resulting in reduced energy demands and lower carbon emissions By minimising heat transfer through walls, roofs, and floors, insulation acts as a shield, trapping warmth inside during winter and keeping homes cool in summer

Thermal conductivity: unleashing efficiency

Insulation performance is evaluated by the thermal conductivity Both PIR and PUR provide very low thermal conductivity values, starting as low as 0.022 W/mK indicating its ability to impede heat flow effectively This attribute is vital for maintaining stable indoor temperatures, reducing the need for excessive heating or cooling and ultimately curbing energy consumption

All of which translates into tangible benefits for house buyers; minimising heat

loss or gain through the building envelope, enhancing energy efficiency, reducing reliance on HVAC systems and creating a comfortable living environment year-round. As a result, this will make Net Zero homes more attainable and costeffective in the long run

Durability and longevity

In addition to its thermal performance, PIR and PUR insulation also provides durability and longevity, with little or no maintenance required during the life of the building With its resistance to moisture, mould, and pests, the insulation maintains its effectiveness over time, offering long-term energy savings and reduced environmental impact.

Value for money

Installing high performing insulation into a building is likely to bring economic advantages as these building improvements will result in reduced energy consumption

Moreover, government initiatives and financial incentives could further mitigate any cost barrier. Various programs, such as grants and rebates, are available to support some homeowners in their pursuit of energy efficiency. By taking advantage of these incentives, homeowners can reduce the financial burden associated with home improvements and expedite the transition to Net Zero homes

Beyond

u l t i n g i n c o n s i s t e n t a n d c o m f o r t a b l e i n d o o r c o n d i t i o n s

Additionally, good insulation can contribute to noise reduction, creating a quieter and more peaceful living environment The thermal and acoustic benefits of insulation not only enhance comfort but also improve the quality of life for house buyers

Good Insulation is an essential first step on the journey towards achieving Net Zero homes By leveraging highperformance materials, homeowners can unlock substantial energy savings, reduce carbon emissions and create sustainable living spaces

As we strive to address climate change, the fabric first approach, where the external envelope of a house is made as thermally efficient as possible, is crucial for creating sustainable homes

Embracing and utilising the performance of insulation is a decisive step towards a sustainable, energyefficient and environmentally conscious future, not just for us but for future generations as well

Tak ing the pressure

The main function of thermal insulation is to provide thermal performance, so products are often specified for efficiency first and compressive strength second. This can result in the specification of insulation with good thermal performance but distinctly average compression behaviour, says Rob Firman, technical and specification manager at Polyfoam XPS.

Insulation products must be capable of bearing the loads imposed on them. A better understanding of compressive strength declarations can help with making more informed decisions at the design and specification stage It can also avoid changes being made on site that could result in a shortfall of both thermal or compressive strength performance.

W h e n a d e c i s i o n i s t a k e n b a s e d o n t h e r m a l p e r f o r m a n c e o n l y , i t c a n m e a n t h a t o n l y l a t e r d o e s i t b e c o m e c l e a r t h a t a p r o d u c t w i t h a h i g h e r c o m p r e s s i v e s t r e n g t h s h o u l d h a v e b e e n s p e c i f i e d –l e a d i n g t o p o s s i b l e p r o b l e m s w i t h i n s t a l l a t i o n o r c o m p l y i n g w i t h b u i l d i n g r e g u l a t i o n s

Take a typical ground floor construction. Compared to concrete slab and screed layers, which are capable of bearing greater loads, thermal insulation can be considered the ‘weakest’ layer. It is – or should be – subject to the most scrutiny, although this scrutiny often only happens later in a project

One possible reason for insulation materials being poorly specified from a compression behaviour point of view could be confusion over how their performance is declared

Compressive strength and compressive stress

Based on the applicable test methods, behaviour under compression should be talked about as compressive strength or compressive stress

l When a load is applied to the material and the material fails (is at yield) before it has been compressed by 10% then that load is the compressive strength of the material

l If the material can be compressed beyond 10% relative deformation before being at yield (i e , its compressive strength is not reached) then the load at which 10% relative deformation occurs is the material’s compressive stress at 10% strain

Across the insulation sector, behaviour under compression is generally compressive strength, as most common insulation materials fail before they are compressed by 10%. Some product literature may say that a given figure is “at yield”, referring to compressive strength

However, there can be confusing uses of terminology in product literature and certification, especially around the 10% compression threshold We would always recommend engaging with a manufacturer directly to confirm the exact behaviour

Alternative compressive strength declarations

C o n f u s i o n c a n a l s o a r i s e d u e t o t h e w a y d e c l a r a t i o n s a r e m a d e f o r o t h e r a p p l i c a t i o n s . F o r e x a m p l e , d u e t o t h e h i s t o r i c u s e o f e x p a n d e d p o l y s t y r e n e ( E P S ) i n s u l a t i o n i n c i v i l e n g i n e e r i n g p r o j e c t s , w h e r e t i g h t e r t o l e r a n c e s a r e r e q u i r e d , d e c l a r a t i o n s a r e m a d e b a s e d o n 1 % c o m p r e s s i o n , a s w e l l a s 1 0 % c o m p r e s s i o n

Extruded polystyrene (XPS) is not used in the same applications With XPS, we don’t make declarations for 1% compression and it is inappropriate to try and equate the two different declarations, as the products are intended for different uses. For typical floor and flat roof insulation applications, a 1% declaration is not relevant

Why might a structural engineer deviate from compressive strength declarations? While insulation manufacturers make declarations about compression behaviour, typically it is a structural engineer who must determine whether a material’s compressive strength is suitable for the intended application. Insulation manufacturers simply do not have structural engineering qualifications or experience

It must also be kept in mind that the compressive strength results declared by testing do not equate to the loads that can actually be applied on site. If they did, products would fail in use

To help keep the use of products within safe limits, factors of safety are employed Applying a safety factor accommodates uncertainty in the design process, emergency situations, and higher-than-expected loads However, using a safety factor should not be taken to mean that a construction is ‘safe’ –there are too many other factors in play to draw that conclusion

Safety factors can be applied at various stages of design and specification. In fact, there is a risk that several can be mixed together, leading to a product being deemed unsuitable even when its use would be acceptable

A structural engineer is likely to employ lower safety factors, often from 1 3 to 1 7, depending on their confidence in test data, risk involved, and the likelihood of issues during installation, among other considerations However, they might also use safety factors in other areas of their calculations

We have seen, for example, situations where an engineer has taken recommended loadings for a given building use in BS EN 1991-1-1 and applied a safety factor to give a design loading When a relatively conservative safety factor is also applied to the insulation material’s performance, it’s easy to see how overspecification could start to occur

Changes to Part L of the Building Regulations are the driving force behind stricter standards and compliance procedures around energy and ventilation performance, contributing towards a roadmap to a Net Zero carbon future and the new homes designed and built now being built having to fall in-line with stricter carbon emissions targets Specifically, to ensure continuity of the air barrier, window and door units will have to connect to the primary air barrier and the frames will need to be taped to surrounding structural openings using airsealing tape.

This comes against the backdrop where evidence points to doors and windows as the main source of the nation’s chronic energy inefficient homes Indeed, it could be said that in the light of product innovation over the years, its perhaps ‘criminal’ that the hundreds of thousands of new or retrofit installations completed each year go unchecked or unregulated, producing a legacy of problems for years to come and costing millions of pounds to rectify This is a pity because with advancements in cost effective, easy-to-use technologies, there's never a justifiable reason for delaying or avoiding the specification of better energy efficient window and door sealing solutions

Air tightness improvements

In this respect, the changes to Part L will have to be seen as a step in the right direction for the new build fenestration sector. It will see requirements for improvements in air tightness, forcing them from 10 air changes per hour down to five air changes per hour and also U-value on windows shifting from 1 6 to 1 2Wm2 k/H, which will require more energy efficient sealant solutions such as thermal foam tapes. The requirement also now states that the frame should be linked back to the wall with an airtight tape

Heat will always find the fastest exit as it comes up against the A+ or A-rated window, and invariably this emanates from the 10mm or so expansion gap left around the window following fitment This is normally left empty, but some amount of spray foam can be injected to fill the void before a silicone trim is applied for a smart looking finish Unfortunately, as expedient as this might seem, none of these solutions create a measurable, long term, high performance thermal, acoustic or airtight barrier – the U-Value of the installed window is simply reduced, which leads to heat escape and, ultimately, financial loss

That’s why the house building industry and wider construction sector deserves better insulating solutions to improve energy efficiencies, particular in

Andy Swift, sales and operations manager for ISO-Chemie, says building regulations requiring windows to be ever more airtight will drive an uplift in energy efficient homes.

the face of a chronic national housing shortage and the need to build more affordable housing

In modular construction, which continues to gain traction – industry sources estimate that out of the 200,000 homes currently constructed annually, about 15,000 of them are modular – and sees continued integration with more traditional methods of building, house designers and specifiers are looking at new ways to deliver low carbon structures, which use sustainable technologies to deliver measurable airtight, acoustic and thermal sealing benefits And this is where self-adhesive foam sealing tapes can add real value, enabling developers to bring forward housing projects more expediently.

They can use ‘smart’ foams impregnated with different substances to create a measurable U-Value as low as 0 6W/m2k, offer superb thermal insulation and can contribute to acoustic sound reduction by 63dB As these installation tapes are completely weather tight against driving rain up to hurricane force wind speeds, installers can quickly apply them around the frame during initial fitting This provides the assurance that they have completed a comprehensive Arated installation rather than just supplying an A-rated window This is a benefit that can be sold on to deliver enhanced energy efficiency advantages for customers and property owners

Straight to L

With the latest version of Approved Document Part L now in force and the new Future Homes Standard on the horizon, it can be challenging to keep up with the changing legislative landscape.

While Net Zero 2050 may seem a long way off, reaching such an ambitious goal is going to entail significant changes to the way homes are built in the UK –and these must happen at pace, with each progression upping the ante in terms of energy efficiency However, adapting to such rapid advancement is no mean feat, and can create uncertainties about how to integrate these changes into the project design

What’s more, the compliance timeline for adoption of the new Approved Document Part L has been shorter than ever before The regulations came into effect last summer but the grace period for houses at planning stage extended only until June 2023, meaning many developers have had to change gear –often requiring design changes to be made mid-development This is because the new regulations will apply to all individual plots where building work had not commenced by the deadline of 15th

June this year, whereas in previous revisions to the Building Regulations, adherence to the changes could be avoided if work had begun on the site as a whole

The revisions to Part L – the first for eight years – are extensive, with the fabric-first approach requiring a strong focus on insulation, mitigating overheating and prevention of thermal bridges What’s more, for the first time, developers will be required to provide photographic evidence of construction process, which must be made available to both building control and homeowners Demonstrating that the building has been constructed as intended in the design, this new requirement will go some way towards reducing the likelihood of as-built performance gaps

Significant though these revisions may be, housebuilders will soon find themselves faced with even further changes, with the new Future Homes Standard approaching in 2025 While the

Andrew Orriss from the Structural Timber Association looks at how timber construction can help the industry address these new requirements.

exact detail of the new standard is still to be announced, it will require new homes to be futureproofed, using low carbon energy sources for space and water heating, and delivering exacting standards of energy efficiency It’s likely that improved insulation and high levels of airtightness will be prioritised, as well as the need for good ventilation –mechanical, most probably – and resilience to over-heating.

Complying with these new standards, particularly given the rapid pace of change, will be a big ask for all those involved in housebuilding A key challenge will be around wall thickness, which

if using traditional masonry methods of construction – is likely to increase significantly in order to accommodate the extra levels of insulation This leaves developers with the conundrum of whether to decrease the internal dimensions (and potentially limit the buyer appeal of their properties) or to increase the external footprint While enlarging individual homes by a few centimetres might not seem too problematic, the limitations become more

apparent when replicated across an entire development – and in the worst-case scenario, could even reduce the number of properties that can be built on a particular piece of land

Choosing to build using timber frame is an effective way to overcome this challenge – primarily because timber frame allows for high levels of insulation to be incorporated into the structure, without significantly increasing the wall thickness As a particularly versatile construction method, timber frame is the ideal structure with which to deliver extremely low U values, in order to comply with the new regulations

Recognising this, the STA has developed design solutions to meet the heat loss standards required by the new Approved Document Part L and the expected requirements of the Future Homes Standard In collaboration with the Future Homes Hub, these solutions have been incorporated into Part L 2021: Where to Start, a guide to timber construction for housebuilders and their advisors

The guide offers example specifications for a variety of construction elements, including external wall constructions using timber frame that can achieve U Values as low as 0.15 W/m2K. The solutions have all been successfully fire tested and the results will be published in the updated version of guidance document Structural timber buildings fire safety in use guidance Volume 1 – Pattern book systems, which will be published soon

Going underground

In an official statement recently issued by the GSHPA’s Council, the association acknowledges the importance of addressing environmental concerns and ensuring the responsible use of heat pump technology. These initial comments pertain specifically to closed-loop ground source heating and cooling systems, and the GSHPA anticipates further updates and amendments as additional information becomes available.

Effective from October 2nd, 2023, the ‘General Binding Rules’ (GBR) will apply to closed-loop ground source heat pumps It is essential to highlight that these rules are applicable solely to new systems implemented on or after the aforementioned date.

Key aspects of the GBR include:

1. System Integrity. The closed-loop system must be fully sealed to prevent leaks and contamination

2 Heat Release Threshold Users must ensure that the system does not release heat beyond a specified threshold While the exact threshold is yet to be defined, it may align with Schedule 3 of the EPR Regs 2016 for open-loop systems This threshold aims to prevent undue warming of groundwater

3 Proximity Restrictions Closed-loop systems should not be placed adjacent to septic tanks or cesspits, within the inner zone of a source protection zone (SPZ 1), within 250m of protected sites (e g SSSI) or ancient woodland (with some exceptions), within 50 metres of a well, spring, or borehole supplying water for domestic or food production

4. Equipment Standards. All equipment used in ground source heat pump systems must comply with British Standards and GSHPA standards.

5 Decommissioning Safeguards Operators must ensure that the eventual decommissioning of these systems does not pose a risk of pollution

While the GSHPA anticipates that the number of systems impacted by these regulations will be small, the association is committed to working diligently to ensure that where EPRs do apply, the process is as simple and manageable as possible Deviations from the GBR necessitate the application of a Bespoke Permit from the Environment Agency before drilling can commence It is worth noting that the Environment Agency plans to engage with stakeholders regarding these regulations, although specific dates for these engagements have not yet been published at this time.

Load bearing out f it

Hilti has launched a new and improved version of its innovative wearable EXO-O1 skeleton, the EXO-S, offering relief for above shoulder level tasks and with broad suitability across many applications. Designed and produced in conjunction with Ottobock Industrials, the updated skeleton features an even more inclusive design able to fit a more diverse range of bodies, with additional support and comfort.

Musculoskeletal disorders (MSD) are a significant cause of health problems in the workplace, accounting for some 60% of all workplace health issues within the EU

In construction, they are an even more pressing problem, with workers tasked daily with repetitive overhead and over-shoulder jobs leading to an increased risk of injuries, time off and a lack of productivity and, sometimes, early retirement

Risk factors on a jobsite split into four broad categories: the task at hand (does the task require repetitive movements?), the individual (age, gender, physical capabilities etc), the load being dealt with, and the general environment – this could refer to poor lighting, constrained space, or movement between floors/levels. Many tasks in construction require working with multiple risk factors, which can increase the risk to develop MSD in future.

Ergonomic best-practice tells us that to reduce the risk of these kinds of injuries we must aim for construction workers to be in a posture as neutral as possible and

to avoid excessive or high-frequent effort Load-reducing exoskeletons are vital for this and are designed to complement other health and safety solutions such as moving & lifting aids

Hilti’s new EXO-S is:

l Suitable for all-day use Providing freedom of movement and weighing just 2 4kg, EXO-S is one of the lightest shoulder exoskeletons currently available.

l Customisable A neck support could be added for extra relief during the most demanding overhead tasks

l Easy to adjust Pre-defined small/medium/large steps make it easy to adjust to different bodies, which means more sharing amongst workers. Comfort for bicep circumference up to 40cm (16”)

Research shows us that the average time off work from MSDs is around three weeks, with many impacted taking early retirement, impacting their own finances as well as the productivity of companies they work for With a new generation of construction workers more aware of risks and unprepared to forfeit their own health, companies are also now in a position where they are expected to make provisions to prevent injuries from repetitive strain

Yale claims that its Expede Window Bracket can revolutionize housebuilding, potentially cutting construction time by up to three weeks

The bracket enables fully glazed windows to be embedded into external timber wall panels at the factory, guaranteeing a consistent factory finish and enabling them to be delivered to site as a flatpack.

The design promotes faster installation on-site. After timber panel setup, the window is adjusted to the desired distance and locked in place This speeds up the building's sealing process, making it watertight in just a day, paving the way for both internal and external trades to commence, which can trim up to three weeks off the total building schedule and so cut overall site costs

There is minimal risk of damage and no extra logistical footprint because the window remains sheltered within the timber panel during transport Furthermore, this method decreases risks associated with manual labour and high-altitude tasks

Crafted and rigorously examined in the UK, the Expede bracket has proven its durability, withstanding over 200kg loads for extended periods and resisting corrosion Available in two sizes, it also comes with Yale's Lifetime Guarantee

The inside view: maximising show home value

There’s no denying that show homes are one of a housebuilder’s most important marketing tools; people will always want to touch, feel and experience a home. But when markets are challenging, and competition high, how do you keep a show home current to maximise its value? Steve Hird, director at Edward Thomas Interiors argues it’s all in the detail.

First and foremost, a show home is there to add value and help house hunters become more invested in a potential move Ultimately a customer is buying a blank canvas, so a well-designed show home should make the buying journey more exciting, inspiring potential purchasers to think creatively. Not forgetting of course, they can also be exceptionally useful tools for plots that are compromised or to showcase a new house type that people ‘don’t get’ on plan

Where to start?

Before issuing a brief to your interiors team, think about longevity, location and layout How long do you expect to be selling from this show home? The average lifespan is between two and three years, so its design needs to be as forward thinking as possible. Furniture and fabrics typically follow fashion, so you can look to this industry for examples of trends that will be upcoming.

Location is just as critical If a show home isn’t specifically designed for a location or house type, it can end up with furniture that doesn’t enhance the space(s), or a design that simply doesn’t match the neighbourhood It needs to have relevance so draw inspiration from local landmarks, sports teams, heritage, or the environment

Of course, presentation and styling are essential If there’s features of the layout you want highlighted, discuss these with your design team from the outset, don’t make them an afterthought Pick out details that video or photograph well, this is essential not just for your own social media content but to encourage visitors to post and share their discoveries too

Once a show home has launched, remember not to neglect it This includes basic housekeeping like replacing room diffusers and hand soaps, washing or steaming bed linen and towels to avoid sun damage, but can also incorporate more significant upgrades Show home refreshes are popular right now, from big budget overhauls to more thoughtful alterations, and can be implemented for various reasons.

Some of these are simply age-related, they just need a revamp to modernise colours, materials or lighting. Some are trend-led, so a children’s playroom might now be better suited as a home office Some are about illustrating how a family can grow with a home, for example, we’ve just updated a nursery to remove the cot and replace with a child’s bed

Then of course there’s customer feedback We want to remove any negative obstacles If a room layout is proving awkward or if visitors are struggling to visualise space, then redo it For example, we’ve replaced bunk beds with twin beds to better showcase the size of a room
