Welcome to the July issue of PSBJ...
July marks an interim period for many in various fields, particularly in the public sector, as we await the results of this month’s general election to guide any changes in long-term planning, policy focus and legislation. That said, day-to-day operations must continue. It’s is also a time when many educational institutions start preparing for school holiday building and improvement works.
For many institutions – whether primary, secondary or higher education – these works will involve acoustic optimisation within teaching spaces. It’s well known that the noise quality of a classroom significantly impacts the productivity and learning abilities of students. However, when you shift from a traditional classroom to a sports learning environment, with larger areas and additional distractions like balls and louder noises, learning can become even more challenging. In this issue, Ben Hancock, Managing Director of Oscar Acoustics, explains why acoustic treatment is essential for sports performance and how it can enhance the overall experience. Turn to page 34 for the whole story.
Elsewhere, Lindsey Mitchell, Architect Director at BDP, explores the evolution of education environments in Scotland over the past decade on page 08. Additionally, Tim Fry, Director at Arup and Eve McLoughlin, Centre Lab Manager at the Sainsbury Wellcome Centre at UCL, examine how the booming life sciences sector in the UK is driving demand for more high-quality lab facilities in central urban areas, using the Sainsbury Wellcome Centre (SWC) in central London as a prime example.

Green light for new facilities at Islwyn High School
Islwyn High School in Oakdale is set to benefit from a new multiuse games area (MUGA) and the development of a new specialist pupil support area. Caerphilly County Borough Council’s cabinet unanimously approved proposals to provide financial support of £145,000 for the project from the Community Infrastructure Levy (CIL) fund. Caerphilly Homes, the council’s housing division, will be project managing the development of the new facilities. The MUGA will replace the one located at the former Oakdale Comprehensive School site, as the brownfield site is being transformed by Caerphilly Homes into an ambitious mixed-tenure housing development. The new MUGA will be located within the grounds of the school, with the community able to access the facility outside of school hours. Located in the same area, the school will develop a multi-disciplinary pupil support facility that will enable and empower pupils to learn, change and manage their lives more constructively.

State-of-the-art swimming facilities completed at Merthyr Tydfil as part of £6m investment
Brand-new swim facilities at Merthyr Tydfil Leisure Centre have now opened, thanks to a £6m investment secured by Merthyr Tydfil County Borough Council. The regeneration project, led by Alliance Leisure through the UK Leisure Framework, sees swim facilities reintroduced to the leisure centre after an extended period of closure, with modular pool provider Myrtha Pools leading the expert installation. Works have included the development of a new 25m, six-lane main pool, a dedicated teaching pool offering a full swimming education programme, plus a new splash pool designed to inspire water confidence and deliver engaging sensory experiences for toddlers. The changing facilities have also been redesigned to improve the overall visitor experience. In addition, efficient heat and circulation pumps plus extra solar panels have been installed in a move that is expected to significantly reduce carbon emissions. The leisure centre remained open throughout the build, so people could continue to benefit from the sports hall, racket sports, fitness suite and exercise studios.
Esh Construction to build Bishop Auckland’s new bus station
Esh Construction is delivering a new bus station in Bishop Auckland after being awarded a £6.4m contract by Durham County Council. The contract follows Esh’s £1.8m package to carry out enabling works on the site. The new station will offer modern and accessible facilities to passengers, with eight stands and improved passenger information. It will also house a retail kiosk, CCTV and more toilet facilities, including an accessible toilet, Changing Places unit and a parent and child facility.

The scheme forms part of an £11.8m investment in the town, with funding secured through the Future High Streets Fund and an additional £3.6m from Durham County Council. Esh Construction commenced the enabling works in February, with works including the excavation and clearance of the existing hard surface to facilitate a new drainage system for the new bus station. Seven attenuation tanks have already been installed. A new sub station will be built to provide the necessary power requirements as well as new retaining walls and the installation of a sub base.
Morpeth Leisure Centre now multi-award-winning with latest national recognition
A sport and leisure centre in Morpeth is celebrating becoming a multi-award-winning facility after winning the Community Benefit award at this year’s RICS North East Awards. Since opening its doors in April 2023, the centre has seen huge engagement from the community, with an increase of 200 to 260% in swim, gym and class visits, as well as a 165% increase in community members. The project has now won best ‘Community Benefit’ at the RICS North East Awards and ‘Design Excellence’ at Insider’s North East Property Awards. This comes after being ranked as ‘best in the country’ in a Quest appraisal last year. Bookending the existing high street, the centre sits at the edge of town beside the River Wansbeck on Gas House Lane. In addition to offering sporting facilities – including a six-lane swimming pool and spectator gallery, learning pool, spa and fitness suites, alongside multi-use sports halls and studios –this facility acts as a local community hub. Morpeth Leisure Centre was commissioned and funded by Northumberland County Council and Advance Northumberland, designed by leading firm GT3 Architects and constructed by Willmott Dixon.
Four-year improvement works elevate high
school in Brentwood
A significant four-year programme to improve pupil accessibility and retention has been completed in Essex, delivering upgraded facilities in line with modern teaching standards. The restoration of Brentwood County High School, undertaken by two of construction’s leading industry names, has seen the introduction of two new specialist teaching blocks, a refurbished sports hall, landscaping and a multi-use games area, greatly benefitting student learning and teaching experiences. The project was carried out in phases in a live working environment, also seeing careful restoration of the school’s spectacular main building, which is considered a heritage asset under its original 1930s design. Demolition work was also undertaken on existing teaching facilities to make way for the new blocks, which focus on art and design technology, science and general teaching. Multi-disciplinary consultancy Pick Everard is behind the programme, operating via formal appointment to deliver architectural services, with contractor Bowmer + Kirkland appointed through the DfE Construction Framework.
Central Building enhancement works commence at Castle Meadow Campus, Nottingham Wates’ Paul Chandler announces retirement
Refurbishment works have begun to transform the Central Building at the University of Nottingham’s new Castle Meadow Campus. Delivered by Midlands contractor G F Tomlinson, the refurbishment works will breathe new life into the Central Building, which sits on the site of the former HMRC offices. The Castle Meadow Campus is a zone for entrepreneurship and innovation in the city centre, with a sustainability strategy implemented by the university that assesses each development to ensure carbon-neutral targets are being met. Encompassing seven buildings, it features state-of-the-art facilities for its community of students, academics and industry partners. The Grade IIListed Central Building is undergoing extensive renovation works, including the complex replacement of the tensile fabric roof to ensure a futureproof building and the addition of a new mezzanine at first-floor level, offering views of the roof through a large, glazed roof light at its centre. A new welcome reception area will provide unobstructed views from the entrance into the heart of the building. Alongside this, a new bistro cafe with kitchen facilities, study spaces and external seating will provide a social space accommodating over 200 visitors.
Paul Chandler has announced that he will be retiring from a full-time executive role at the end of 2024 after a distinguished 42-year career in construction. Paul has been Executive Managing Director of Wates’ Construction Group since 2017 and a member of the Wates Group Board since 2018. Under his leadership, the construction group has flourished, increasing its turnover from circa £700m in 2015 to circa £1.3bn in 2023, delivering profitable growth year on year in an incredibly challenging period for the industry. Since Paul has been at the helm of Wates Construction Group, the business has delivered several major projects of national significance. This included building the state-of-the-art Sandwell Aquatic Centre for the Commonwealth Games and transforming this into a legacy for the local community as a leisure centre for everyone. Another major project completed under Paul’s leadership is Borough Yards, a vibrant retail and leisure development created in disused Victorian railway arches in the heart of London. This project won the MIPIM award for best urban project in 2022. Paul will remain a member of the Wates Group board and continue to lead Wates Construction Group until the end of 2024.
TRANSFORMING SCOTTISH SCHOOLS
The evolution of education environments in Scotland over the last 10 years is creating spaces that preside over a significantly improved school system in the country, says Lindsey Mitchell, Architect Director at BDP.
The provision of high-quality outdoor spaces that include covered space is supporting the initiative to connect young people with nature. Moreover, when school holidays arrive, school buildings become part of the community – part of something bigger than themselves. Inspired by Scandinavian countries and their approach to making the most of outdoor spaces, schools are also building learning and social environments that spark imagination and creativity, encouraging children and communities to connect with the outdoors.
Another really positive attitude shift has been in the recognition of the diverse learner population and the different ways people learn. Personalisation of education is one of the primary aims of the Scottish Government’s policy ‘Getting it right for every child (Education)’, and as architects and creators of education spaces that facilitate this approach, it is important that we, too, get it right for every child.
A vast amount of research has been published that links well-designed education buildings to improving academic performance, learner attainment and attendance. Various factors such as natural light, noise levels, temperature, air quality and classroom orientation all impact on both learners and teachers. Flexible seating options can help to encourage participation and collaboration as well as independent work. Technology also has a key role to play and, as a result, teaching is no longer confined to within the classroom walls.
A prime example of this design intention is the Maybole Community Campus. Located in the historic market town of Maybole in South
Ayrshire, the new campus is a testament to contemporary design and sustainable innovation in the educational sector. Designed by the Glasgow architecture team at BDP, this project not only redefines the educational landscape of the town but also enhances the community’s interaction with shared spaces.
The project, located on Kirkoswald Road, spans 10,397m2 and represents a significant investment of £55m. The project, a collaboration between BDP, Morgan Sindall and South Ayrshire Council, exemplifies a commitment to designing indoor and outdoor educational environments that are supportive of 21st-century pedagogies.
Maybole’s historical significance as a market town and main thoroughfare to Stranraer has long been a defining feature. The recent completion of the Maybole bypass has significantly reduced traffic, making the town safer for children accessing the new Maybole Community Campus. Situated on the west side of Maybole, on the existing Carrick Academy site, this campus represents a significant step forward in educational infrastructure for the local authority.
The new Maybole Community Campus is a multifaceted educational hub that includes a nursery, two primary schools (St Cuthbert’s Primary and Culzean Primary) and a secondary school (the new Carrick Academy). The new design is based on a single building approach with identifiable zones that allow it to respond to the surrounding context. The four zones are a welcome space, a learning hub and early years hub and an active hub.
The layout is designed to allow scope for future flexibility and adaptability. All classrooms are well proportioned, have
good natural light and views out to the rural setting. All rooms and teaching spaces are within easy reach of a central ‘heart space’ that sits within the learning hubs and is defined by a circulation loop – an open balcony activating the upper floors of the atrium to create a vibrant and dramatic school environment.
Additionally, the campus features a four-lane, 25m swimming pool, a sports pavilion for community use, two full-size rugby pitches and a police office, co-locating all of the town’s educational facilities with important community spaces.
BDP’s design adheres to the stringent guidelines of the Learning Estate Investment Programme (LEIP), targeting operational energy use of 67kWh/m² per annum for core school hours. The campus incorporates several sustainable design features, including triple glazing, super insulation, improved airtightness and the elimination of thermal bridges. The compact form of the building and the orientation of classrooms support a passive design approach, reducing energy consumption and enhancing user comfort. The all-electric campus aligns with South Ayrshire Council’s goals to reduce carbon emissions, making it a model of sustainable development in educational facilities.
A critical element of the project’s success was the extensive stakeholder consultation. BDP engaged with pupils from all schools, parent councils, school staff, SAC sports and leisure and local community groups, including the rugby club. This feedback ensured the design met the diverse needs of the community and the educational goals of the campus.
The project faced significant challenges, including development during the pandemic, material shortages and inflated prices. The BDP team continually reassessed materials to ensure the project stayed true to the approved planning scheme. Phased openings allowed for initial student access, followed by the community sports facilities, ensuring minimal disruption.
The phased completion approach saw the new schools operational by August 2023, leisure facilities by January 2024, and full project completion anticipated by August 2024. The final stage includes demolishing the original school, with materials retained for reuse in the new landscape design, preserving keystones and date stones for the Ayrshire Archive at the Ayr Grammar campus.
Ultimately, the Maybole Community Campus accommodates up to 1370 pupils, offering contemporary learning environments in a modern, state-ofthe-art building. The design promotes seamless transitions between educational stages, connects outdoor and indoor learning spaces and encourages consistent community use. Shared physical education facilities and the integrated nursery enhance collaborative learning and community engagement.
As Maybole shows, the Scottish education system is now experiencing the benefits of increased investment in education, a power devolved to the Scottish Government. The £2bn Learning Estate Investment Programme (LEIP) has been instrumental in funding projects across the majority of local
authorities – 47 as of December 2023. This progressive funding model allows local authorities to reclaim funding over a 25-year period, provided they meet a range of criteria, including operational energy targets, embodied carbon and zero emissions heating.
Architects in Scotland are encouraged to actively consult with children, parents and the wider community on school projects, ensuring that those directly affected are at the forefront of the discussion. This approach has led to more innovative and community-focused designs such as this one.
BDP’s work in Scotland, such as at Maybole Community Campus and the recently-completed Newmains & St Brigid’s Community Hub in North Lanarkshire, exemplifies this success. These projects are winning multiple design awards for their outstanding design. They serve the local community for a variety of activities, from out-ofhours football to breastfeeding support groups and children’s parties.
The Maybole Community Campus stands as an exemplar of the power of thoughtful, sustainable design in creating vibrant, functional spaces for education and community use. This project not only transforms the educational experience for the children of Maybole but also enhances the town’s community life, setting a benchmark for future educational infrastructure projects in Scotland and across the UK.
TOP TIPS FOR SUSTAINABLE ROOF DESIGN AND INSTALLATION
Carl Bailey, Regional Technical Manager for Elevate UK & Ireland, part of the Holcim Group, offers advice on how to design and install a more sustainable roof.
The construction industry has a vital role to play in responding to the climate crisis. In the UK alone, 39% of carbon emissions are directly attributed to the built environment. On top of that, the average home loses almost 25% of its heat through the roof space.
To address these issues and meet netzero targets, the need to reduce buildings’ operational and embodied carbon is more pressing than ever. The roof design of public buildings, ranging from schools to hospitals, can help to tackle this challenge, so here are my top tips on what to consider during specification and installation.
Review a product’s lifecycle
Adopting a fabric-first approach that prioritises the building envelope in the early design stages will result in a more energy-efficient property and enhanced thermal performance.
Your choice of roofing materials will also contribute towards environmental performance. How these materials have been produced, their packaging, recyclability and overall impact on the building’s lifespan can all affect sustainability, so they should be carefully considered during specification alongside performance requirements.
To help research these factors, an Environmental Product Declaration (EPD) will independently confirm what a product is made of and how it impacts the environment across its entire lifecycle from the production and in-use stages right through to the end of life.
Weigh up your waterproofing options
The waterproofing layer is a crucial component of a sustainable roofing system. Single-ply membranes are ideal for flat and low-slope roofs on public buildings offering a durable solution, which is quick, easy and cost effective to install.
A single-ply membrane provides waterproofing in a single sheet and has a low environmental impact. The main types in the UK are EPDM (ethylene propylene diene monomer), PVC (polyvinyl chloride), TPO (thermoplastic polyolefin) and PIB (polyisobutylene). All are compatible with green and blue roofs as well as solar panels.
Thanks to the improved formulation of single-ply membranes, the release of carbon during operational use has been almost eliminated. The product’s longevity has increased, too. A correctly-fitted singleply roof membrane will provide long-term protection for a public building. Single-ply
membranes independently certified by the British Board of Agrément (BBA) will last for at least 30 years. EPDM and PIB have the longest life expectancy of all single-ply products with many third-party assessments indicating 50 years and beyond.
A further sustainability benefit is recyclability. For refurbishment projects, it is estimated that up to 80% of singleply membranes can remain in place as an underlay. If the roof does require stripping, it is possible to recycle the old single ply although the level of recyclability will vary depending on which type of membrane is selected.
Adhere to installation guidance
An effective installation is key to maximising sustainability as it will help to enhance the life of the membrane and the roof.
Poor workmanship during installation may, ultimately, cause the membrane to fail. Correctly applying joints and flashings is critical to ensure watertightness and minimise the risk of water ingress. Junctions between different materials are a common problem area, so contractors are advised to seek advice from the membrane’s manufacturer to check if different materials can work in cohesion.
Removing rainwater from the roof as quickly as possible is also vital. British Standards BS 6229 and BS 8217 advise that flat roofs should be designed with minimum falls of 1:40, ensuring a finished fall of 1:80 can be achieved, allowing for any inaccuracies in the construction.
A roof that does not comply with these minimum, industry-accepted standards is likely to attract ponding water, moss, fungal and algae growth, leading to increased loading, maintenance costs and the risk of water ingress if a defect or damage affects the roof coverings. Failing to comply with these standards may also negate third-party insurance cover and or a manufacturer’s guarantee.
Seek technical support
When specifying and installing a roofing system, take advantage of manufacturers’ technical expertise. When selecting a waterproofing membrane, for example, you should expect to receive information such as NBS specifications, a cut-to-falls insulation design, wind load and thermal calculations, regulatory compliance and confirmation of a third-party accreditation, such as BBA.
For the best peace of mind, seek a manufacturer that can produce all the required layers in the roof system. This ensures compatibility and provides a single point of responsibility throughout the roof system’s life.
A manufacturer’s technical advice in a project’s early stages should also ensure the most appropriate roofing system is developed and the membrane is applied in accordance with their guidelines. Once the system is approved by a technical services team and executed by a trained, authorised or licensed contractor, a long-term warranty can be provided.
VIRTUALISATION – A KEY ENABLER OF CONSTRUCTION CIRCULARITY?
Martin Huber, CEO and Co-Founder of 3D modelling and spatial data company Amrax, discusses how 3D visualisation can help public sector builds embed circularity.
Materials, machinery, people and energy: The construction sector remains in constant motion. How we reconfigure that flow into a circular course that promotes the reuse, repair and recycling of materials and aims to keep resources in use for as long as possible is an established net-zero priority. In fact, it’s estimated that transitioning to a circular economy could reduce global emissions by up to 39% by 20501 .
But while construction continues to make progress, there is still a big job to do. Roughly half of all raw materials we extract go into the world’s built environment. Construction also creates an estimated third of the world’s overall waste2 .
As environmental concerns grow, tackling this by embedding deeper circular construction practices at pace and to scale is coming into much sharper focus. This becomes even more important in the context of the public sector built environment where there’s a role to play in leading by example and driving the broader shift towards circularity and sustainability. While this is certainly no easy feat, the good news is that the sector already has many of the tools and technologies at hand to make this happen.
One proven example can be found in the adoption of virtualisation to enable predemolition circularity. By combining AI
and 3D spatial planning, it is now possible for architects, engineers and construction professionals to digitally assess which parts of a building or site can be reused in a new project or repurposed in other ways. This approach can apply to everything from construction materials through to furniture and fixtures. For example, an architect may be able to determine that the doors in a desolate property can be easily slotted into a new building concept they are working on and brought back to life in a new way.
Another huge benefit is the scope for collaboration. By enabling all stakeholders within the complex construction chain to collaborate in real time, it becomes easier to collectively identify opportunities for improving resource efficiency and implementing circular construction principles and, in turn, implement them through the entire process of a build as it happens. This can include everything from sustainable specification through to ensuring Design for Disassembly.
As a final point, once the initial works are done, this approach can continue to play a huge role supporting ongoing circular economy strategy. For most building operators, of course, one of the biggest priorities at the moment will be reducing costs and emissions without compromising the overall functionality
of a building. By using 3D visualisation in conjunction with BIM, it becomes easier to track and proactively maintain and repair assets as required to extend their lifespan and reduce the need for replacements. Better space management is a benefit, too. This is because it makes it easier for operators to gauge any underutilised areas that can be reused or better used, thus maximising the value of every inch of available space without the need for new construction or expansion.
In the next few years, there is no doubt that the construction industry must intensify its efforts to achieve deeper circularity and mitigate environmental impact. With virtualisation making it easier to take advantage of every single opportunity to reuse, repurpose and recycle, the transition to close the construction loop inches closer.

LAND REMEDIATION IS KEY TO CAPITALISING ON BROWNFIELD BOOST
The Government’s ongoing consultation around making it easier for developers to get permission to build on derelict sites will be pleasing for industry professionals in the UK. It’s no secret that house building is some way away from hitting its required targets, and these changes, if implemented, will undoubtedly help smooth out the process and deliver much-needed homes.
However, while it’s a step in the right direction, there is a lot of work required at these sites to make them viable for construction. David Llewellyn, Head of Construction and Infrastructure at Pagabo, explains that as these pieces of land have been previously developed and fallen into disuse, there’s often a need for decontamination and land remediation.
The levelling up agenda has put an emphasis on transforming towns and cities that have previously been prone to
underinvestment and, as a result, lack the means to host the type of housing required in the modern day. This underinvestment has meant that these towns are now made up of large areas of underutilised brownfield land, which, of course, provides a great opportunity.
As we all know, with the construction industry, opportunities also pose a challenge, and it’s often a case of making key decisions on whether it will be worth it and, in the case of brownfield sites,
much of the industry agrees that it is. The old saying ‘numbers don’t lie’ couldn’t be truer in reference to brownfield sites as statistics from the Campaign to Protect Rural England have identified that redevelopment of these sites could provide 1.2 million homes. However, turning traditionally-industrial areas into land that is fit for homes often requires demolition, decontamination and land remediation, all tasks best left to the experts in these fields.
Bang for your buck
The need for these experts is often overlooked and land remediation is regularly picked up by the main contractor, which nine times out of 10 is subcontracted to a specialist anyway. Clients see this as a transferring of risk but, by negating this risk, they’re not always getting the best possible value for money as those in the supply chain are, quite rightly, making their margin on the project. The main risk being transferred is what lies in the ground, a lot of which is unknown.
Not enlisting the support of specific professionals also presents a knowledge gap around how long sites can take to remediate. This gap has been known to cause a situation that, by the time the client realises the extent of the remediation needed, they are already behind on their project timeline. As such, they will then go down the main contractor package route as they believe it is the most efficient.
By appointing a specialist remediation contractor, work can start much quicker and earlier, meaning that build programmes are shorter, completion dates are sooner, and the time to seeing a return on investment is dramatically reduced – after all, the best land for local authorities to sell or operate on is land that is shovel ready and can provide a quicker return on their investment.
A major challenge
Frameworks are increasingly becoming a more prominent route for clients to get access to the services of a specialist contractor for land remediation, as they typically take away a lot of the legwork and the challenges associated with appointing the via the open market.
In Pagabo’s case, our Demolition and Land Preparation framework was born as a spin out of our successful Major Works framework, with the success of projects of this nature highlighting the market’s desire to quickly and reliably access remediation specialists without having to take on the procurement burden themselves.
There is now an onus on local authorities and developers to work together to unlock challenging brownfield sites and deliver much-needed housing and with that, the demand for specialist skills is one that is only going to grow. With works like land remediation, which is incredibly complex, the need for remediation contractors will almost definitely increase.
With that, the requirement for efficient procurement routes will become increasingly acute, so it is now more important than ever that clients understand that the route that has historically been perceived as the path of least resistance isn’t always the best option.
ANALYSIS OF THE NATIONAL INFRASTRUCTURE AND CONSTRUCTION PIPELINE: WHAT CAN WE LEARN FROM THE PLANS?
Arron Jameson, Keyline Civils Specialist’s Head of Projects, discusses the Analysis of the National Infrastructure and Construction Pipeline 2023 and its impact months on from its release.
I
n an industry navigating a challenging economic environment, an update to the National Infrastructure and Construction Pipeline is designed to provide some welcome certainty. A few months following the release of the Government’s plans and projections for investment, have we seen the confidence boost that the pipeline promised?
Long-term projections creating uncertainty
Despite its intention to provide a positive outline for industry forecasting and aid in planning for construction companies, initial reactions to the plans were lukewarm. Longer-term projections within the plans are, at first glance, a confident – though not ambitious – statement of intent. Projected investment in infrastructure and construction is stated to be in the region of £700bn to £775bn, similar to the previous pipeline, though adjusted to inflation. But a closer look at the figures detailing annual costs, which are frequently dotted with “TBC” or “unknown”, shows a less concrete stance. An admittance in the pipeline that much is to be “determined by the market” brings an ambiguity that belies current industry conditions.
For the short term, where plans are based less on projection and more on current spend, the pipeline has, however, delivered assurances welcomed by the industry. The stated £164bn spend for the two-year period between April 2023 and March 2025 carries a degree of certainty that the 10-year projections do not.
It may be that the pipeline hasn’t instilled huge confidence, but where construction companies are doing all they can to futureproof their businesses, it has provided a useful basis for planning and forecasting. Projected spend reflects shifts in the market that are already in motion, reaffirming the moves the largest contractors are already making – towards sustainability, the energy sector and closer supply chain involvement, to name a few.
Flourishing energy sector
Our industry is facing some uncertainties – reflected in the ambiguity in the pipeline – but not all sectors are suffering for it. Where the traditional sectors are largely stable, but not showing signs of significant growth, the energy sector as a whole is proving to be remarkably resilient.
It’s the fastest-emerging market, as the pipeline highlights – and we’re seeing a shift in priorities among the largest contractors to incorporate its growing importance. As a partner to many of the largest companies in construction and civil engineering, this is something we must, and have prepared to, adapt to. It shows the importance of being agile – as an industry, we must always be aware of projected growth, and ready to implement it.
Some high-profile projects – HS2 being most noteworthy, but also smart motorways – are on hold indefinitely, and some have slowed to a crawl, but the energy sector provides a more positive outlook, especially in terms of solar, nuclear and the fast-moving arena that
is energy from waste, for the industry. An ever-growing emphasis on sustainability and reaching net zero has correlated with a flourishing renewable energy sector. The national infrastructure and construction pipeline suggests this will only continue in the coming years; from supply chain to contractor, this is something the construction and civil engineering industry has to be ready for.
Potential issues delivering the projected pipeline
A projected pipeline is just that: A projection. But, while there’s no guarantee that the expected investment will come to fruition, the industry must prepare for shifting priorities and sector growth.
There are, however, a few roadblocks in delivering the anticipated project pipeline to overcome. The skills shortage is frequently discussed, but for good reason – if we are to deliver the planned investment of £164bn over the next few years, the Infrastructure Projects Authority (IPA) estimates an annual average of 543-600,000 workers will be required. Collectively working to address the labour shortage is already a priority, but we must accelerate our efforts to meet market demand.
Inflation poses another challenge. While the IPA argues that it consistently uses GDP indices to adjust for inflation, there is awareness that “the construction-sector-specific indices have been higher than GDP indices over recent periods”. Rises in material costs due to unforeseen circumstances – the war in Ukraine being one such example – are impossible to predict, and can impact project planning and budgets significantly. Long-term projections have to be met with some caution, therefore, and improving efficiency to account for fluctuating budgets is a necessity.
A further consideration is the deliberate and considered shift that is sustainability; to construct with real consideration around the on- and offsite parameters that affect the built environment can add mounting time, financial and workload constraints to a project. The ability to reflect this in the design methodology, construction techniques and material solutions that are provided, is paramount to the successful delivery of the pipeline.
Modern methods of construction (MMC)
Addressing the skills shortage will require a multifaceted approach. One way for our industry to do so is through the engagement and leveraging of MMC; as demonstrated in the pipeline, this is something that strongly aligns with the future of the industry.
As a supplier partner to the construction and civil engineering industry, we know first hand the benefits it offers: Providing value-engineered, offsite, modular solutions can mitigate time on site, logistical challenges and the level of skill required at the point of installation. Close partnerships and working with experts throughout the supply chain for approaches such as MMC will be key to driving innovation and quality on future projects.
Demonstrating our ability to deliver the slate of projected projects is essential to building confidence in our industry – and as confidence increases, so does investment. Improving efficiency is key to this. Working collaboratively across the supply chain and building relationships from manufacturer through to contractor makes project delivery more efficient, as well as opening up opportunities for innovation – which is often the first thing we lose as budgets tighten. Opening up communication channels and closer collaboration can help the industry meet market demands and protect against fluctuating costs. Focusing on project outcomes and boosting productivity through early supply chain involvement can make the industry more robust and resilient – as we navigate through turbulent external circumstances, close partnerships and doubling down on these – will be increasingly vital.
PUBLIC SECTOR CHALLENGES WHEN RENOVATING LISTED BUILDINGS
The property portfolios of the UK’s public sector contain thousands of listed buildings, all of special architectural or historical interest and some of national importance. With an obligation to preserve these buildings’ heritage while ensuring they are fit and safe for modern use, the task of renovation can often be highly complex. Here, the NU Construction team explain the challenges of renovating listed buildings and the benefits of working with a trusted heritage construction specialist.
Navigating regulations and planning permission
Due to the special nature of private- and public sector-owned listed buildings, they must be granted listed building consent from their local planning authority before any work can begin on alterations or renovations. With a duty to ensure that the building’s heritage is protected and preserved, planning departments require detailed plans about the proposed redevelopment, including how this will impact the character of a building. For instance, they will not only want to know how the finished building will look, but also the materials and building techniques to be used.
Getting plans approved can not only prove costly and time consuming, but the process can also frequently end up being lengthy. Given that the average wait for planning permission in the UK is between eight to 13 weeks, with complex cases for listed buildings1 often taking longer, it’s important to work with a partner that has significant experience and knowledge working through the process to avoid protracted processes that will also impact on deadlines, contractor availability and, ultimately, costs.
One of the benefits of working with a company that specialises in working on heritage projects is the expertise and knowledge they have in both listed buildings and the planning processes, which can improve the chances of submitted plans being approved first time, without amendment. An experienced provider will be able to specify suitable materials and building techniques that are sympathetic to the building and will likely satisfy planning requirements.
A long-established heritage specialist will have the extensive supply network needed to source the right kinds of materials required for the job, also the knowledge to work with them. Moreover, they will also understand that some of the original materials used in these properties will need extra care and attention as they may be damaged by modern power tools and will adopt more sympathetic techniques accordingly.
Aside from planning permission, renovation that involves a change of use, the building of an extension or other significant adaptation also needs to meet Building Regulations. This added complexity makes it vital that any heritage contractor also has a comprehensive grasp of current regulations and legislation.
Safety and security are vital considerations when renovating a listed building. Contractors will not only have to comply with health and safety regulations but will also need to know the types of issues that can arise with older properties, such as weak floors, loose masonry and failing roofs. To protect employees and users, the areas being worked on, and sometimes the entire building, may need to be closed off and secured.
When renovating listed buildings, unforeseen issues can frequently arise. Contractors can discover historical features that have lain hidden for centuries and now need to be preserved, or there can be structural issues that need urgent repair. Experienced heritage specialists will know where these issues are likely to appear and how to address them. Moreover, they will be prepared for these potentialities and will be able to work flexibly to overcome delays and additional requirements.
Cliffe House case study
The challenges of renovating a listed building can be seen from the work done at Cliffe House, Huddersfield. Owned by Kirklees Council, this Grade II-Listed mansion provides bespoke learning and events for schools, colleges and the wider community.
The extensive refurbishment of Cliffe House included reroofing, rewiring, the installation of new heating and sprinkler systems and improvements to the building’s fire prevention system and fire egress arrangements. In addition, the building was internally and externally decorated with repairs prior to painting; floorcoverings were replaced; sanitary and welfare provisions were upgraded; stained-glass windows were fully refurbished and minor amendments were made to the drainage system.
The wide variety of work carried out on the property required a heritage specialist with extensive experience in the development process, together with knowledge of conservation and ecology.
Additionally, a comprehensive supply chain list of accredited restoration craftspeople was required to ensure the most suitable experts were used for the specialised tasks. Specialist contractors, for example, were used to strengthen the structuraltimber, king-post roof trusses; bespoke patent glazing was manufactured to replicate the original glass rooflights and original tiled walls and floors were restored using a specialist heritage tiler.
To maintain the heritage of the building, existing sash windows were also reconditioned. Westmoreland Green Slates and ornate lead flashing were used for reroofing, stonemasons repointed repairs with lime mortar and lime plasters were used to replicate and match existing plasterwork. At the same time, the installation of new heating and wiring required careful consideration and a methodical approach to avoid damage to ornate plasterwork, skirtings and floorboards.
One of the more complex issues was the stained-glass window. Following a full survey by a specialist conservation consultant, the glass needed to be removed from the frame for workshop repair. Panels were taken apart and the glass cleaned, whilst leads and broken glass were replaced where necessary. During repair, the frames needed to be weather protected with clear glass, cut to the same size as the stained glass and fitted into the frame rebate.
By partnering with a specialist heritage construction company like Nu Construction, Kirklees Council ensured the work carried out at Cliffe House restored and preserved the building’s historic features while ensuring it was upgraded and fit for purpose as a community facility. All this was achieved in line with planning requirements and Building Regulations.
THE BIG BENEFITS OF BLUETOOTHENABLED SMART LIGHTING IN PUBLIC AREAS AND BUILDINGS
Lighting control systems are often the unacknowledged ingredient that brings a scene to life – from theatre stages to spectacular art galleries or intimate restaurants. Great lighting not only enhances the aesthetics but contributes to energy efficiency and user comfort, says James Davison, Associate, Specialist Lighting at TGA Consulting Engineers.
f you are looking for more sustainable and efficient lighting solutions, you should consider Bluetooth-enabled lighting. Bluetooth is a way of exchanging data wirelessly over short distances using a radio frequency to transmit data – it creates a short-range network. Operating on a frequency set aside by international agreement, it is extremely secure and Bluetooth devices can communicate through walls and other obstacles.
Here are some big benefits of smart lighting:
1. Energy saving
Lighting is a significant source of energy consumption, accounting for almost 40% of all energy used in public buildings. With a lighting control system, you can save up to one third of the energy used by traditional lighting.
2. Smart lighting can deter crime and prevent accidents
Smart lighting can increase the brightness and visibility in dark or isolated places, such as alleys, parks and parking areas where criminal activities are more likely to occur. It can also dim or turn off lights in areas where there is no activity.
3. It can foster social interaction and inclusion
Smart lighting can have a huge impact on the ambience of public places such as squares, bridges or monuments, while supporting the needs of the elderly or disabled with customised and accessible lighting options.
4. Lighting can be programmed and automated Smart lighting is particularly effective where lighting requirements are not constant, such as in buildings that are used sporadically. Here, fittings with motion or presence/absence detection sensors can be integrated to avoid energy wastage.
5. Accurate control in minute detail
Using a smartphone app, lights can be turned on or off, dimmed to the desired level, or set to turn on and off at specific times from anywhere in the world.
6. It’s well suited to listed buildings
Controlled via wall-mounted wireless switches or scene plates, as there is no requirement for hardwiring, Bluetooth works particularly well within listed and/or heritage buildings where walls cannot be chased out to obscure cabling from view.
7. Smart lighting offers health and wellbeing benefits to staff and other building users
By mimicking the pattern of natural lighting indoors, wireless lighting can be used to enhance circadian rhythms resulting in improved focus and productivity during the day and fewer sleep disturbances at night, which is especially useful within healthcare settings.
8. It is easy to fit and install
Bluetooth-enabled systems are hosted on the cloud so businesses can transition to smart lighting without significant downtime, making it an ideal option for a wide range of settings. Wireless lighting schemes are also incredibly easy to use and operate, being controlled via traditional switches, remote control, app, voice or by using a home ecosystem.

EMERGENCY LIGHTING: DESIGNING AROUND REGULATION
Integrating emergency lighting in public sector buildings while meeting regulations and achieving aesthetic integration is a complex balancing act. Traditional plastic and metal luminaires can look obtrusive against some architectural designs. Adam Barber, Head of Technical at Philip Payne, examines the regulations and explains how the company has launched a wooden emergency exit sign solution.
Striking the right balance requires a cohesive approach from the outset. Regulations and standards must be understood by all stakeholders and incorporated into lighting designs from the earliest stages. This ensures emergency lighting delivers both functional performance and aesthetic integration.
The core fire safety regulation in the UK is the Regulatory Reform (Fire Safety) Order 2005, which mandates adequate emergency lighting along escape routes. However, it supports British Standards, which provide critical technical specifications that designs must comply with. These cover aspects like lux levels, uniformity, run times, positioning of luminaires and stringent product safety testing.
BS 5266-1 is perhaps the most important code of practice, covering emergency lighting system types and defining the different purposes of escape route lighting, standby lighting and openarea safety lighting. Each application has its own requirements around lux level, uniformity, duration and luminaire positioning. Notably, BS 5266-1 states the need for consultation between all parties
at the predesign stage to determine the intended operation of the system.
Two other pivotal standards are BS EN 50172, which covers emergency escape lighting system requirements, and BS EN 1838, which is focused on emergency lighting. The former specifies parameters like minimum light levels on exit signs and the uniformity of lighting levels along escape routes.
In addition to the lighting performance criteria, the physical construction and fire safety design of emergency luminaires and signs themselves are also governed by rigorous standards and testing regimes. This is covered by the BS EN 60598 series for luminaire safety, with additional section 2-22 specifically for emergency lighting. A prime example is the glow-wire test, where a glowing 850°C wire is applied to the luminaire’s material to check its resistance to ignition and fire propagation. This test is crucial when assessing the viability of new, sustainable materials, like wood, that can replace plastic in some applications. While it may seem unlikely that a wooden product could pass such a test, Philip
Payne’s new Arden oak emergency exit sign did just that ahead of its launch. Key to its thermal resistance is the sustainably-sourced oak, a hardwood that has a higher density and slower burn rate compared to softwoods, making it naturally more resistant to fire.
Lighting designers must also refer to application-specific guidance, such as the LG12 CIBSE guide on emergency lighting practices. For sectors like healthcare, standards like HTM 05-02 outline requirements for emergency lighting in areas like hospital wards and theatres.
Undoubtedly, there is a complex web of regulations and standards to navigate when specifying emergency lighting, particularly for public sector projects where safety and compliance are paramount. But, by combining this technical due diligence with innovative cross-industry collaboration, it is possible to satisfy the most stringent codes while delivering emergency luminaires and exit signs that enhance the overall architectural vision.

TRANSFORMING MATERNITY CARE IN BELFAST: THE NEW ROYAL VICTORIA HOSPITAL MATERNITY UNIT
The completion of the new maternity unit at the Royal Victoria Hospital (RVH) in Belfast represents a transformative development in healthcare infrastructure for Northern Ireland. This innovative facility, delivered by the GRAHAM-BAM Healthcare Partnership (GBHP), is set to significantly enhance the birthing experience for over 5000 women annually, demonstrating a strong commitment to providing exceptional maternity care.
A landmark project
Valued at approximately £85m, the new five-storey maternity unit stands as a testament to modern medical design and functionality. Located next to the existing hospital, the unit covers a total area of 17,000m2 and houses a variety of advanced medical amenities designed to support comprehensive maternity care, including ensuite rooms with birthing pools, delivery suites, obstetric theatres and a neonatal intensive care unit (NICU).
The design and layout of the facility have been carefully considered to ensure seamless accessibility and comfort. All essential services are conveniently located on a single floor, which not only streamlines the birthing process, but also provides a stress-free environment for expectant mothers and their families. The facility also includes modern office accommodations, changing facilities and communal areas for the staff of the Belfast Health and Social Care Trust.
Architectural and design features
The architectural design of the new maternity unit is both functional and aesthetically pleasing. The exterior features a combination of Corten steel, known for its weather-resistant properties, Kilkenny limestone cladding and sleek black zinc panels. These materials were chosen not only for their durability but also for their visual appeal, contributing to the building’s modern and welcoming appearance.
On entering the facility, visitors are greeted by a large, open atrium filled with natural light. This welcoming space sets a positive tone for patients and their families. Care is then organised across the three upper floors, with specific areas dedicated to various aspects of maternity care:
Ground floor: Houses maternity assessment, midwifery-led units and early pregnancy units
First floor: Includes maternity theatres, birthing suites and NICU facilities
Top floor: Dedicated to the maternity ward, providing space for both high-risk and postnatal women.
The construction of the building included the creation of two additional storeys below ground level, which house a services tunnel duct and a dedicated area for staff, linking the new facility to the wider hospital complex and ensuring that all necessary services are readily available.
Overcoming challenges
The project faced several challenges over the course of its construction programme, primarily due to its location within a live hospital environment. Construction was carefully planned and coordinated to avoid disrupting the hospital’s critical services. One notable challenge was the proximity of the helipad on the roof of the adjacent critical care unit. Due to the location and use of two tower cranes on site, ongoing communication with the trust ensured that helicopter landings and take offs were not disturbed at any point.
Additionally, the COVID-19 pandemic posed an unprecedented challenge. Construction was temporarily halted for four weeks due to Government restrictions. However, GBHP implemented a robust COVID-19 site mobilisation plan, which allowed work to resume safely. Measures included site-specific health and safety protocols to align with Government guidelines, ensuring the workforce’s safety and minimising further delays.
Phased construction approach
The project is being delivered in three key phases:
Phase 1: Involved substantial substructure basement works and the construction of the new maternity unit. This phase included creating two new levels below ground, housing a services tunnel duct and a dedicated staff area.
Phase 2: Following a 20-week decant period, this phase will involve the partial demolition of the existing Royal Jubilee Maternity Hospital building.
Phase 3: Will include the completion of a two-level prefabricated, steel-frame link bridge between the new maternity unit and the existing critical care unit.
The phased approach ensures that construction activities don’t disrupt ongoing hospital operations. GBHP’s proactive problem solving and collaboration with the trust and other stakeholders are crucial in navigating the complexities of working within a live hospital environment.
Community and environmental impact
The project also emphasised community engagement and sustainability. The site hoarding and overall appearance were maintained to high standards, reflecting GBHP’s commitment to involving local communities. Initiatives included employing a community-based workforce and encouraging participation from local disadvantaged groups.
Sustainability was a core focus throughout the project. GBHP’s sustainability goals included reducing the environmental footprint and ensuring that the building materials and construction practices were sustainable.
Future outlook
The successful completion of the new RVH Maternity Unit underscores the power of innovative design, meticulous planning and collaboration in transforming healthcare delivery. The facility stands as a significant advancement in Belfast’s healthcare landscape, promising to enhance the maternity care experience for thousands of families for years to come.
The new RVH Maternity Unit not only revolutionises maternity care in Belfast but also sets a new benchmark for future healthcare projects. Its completion is a testament to the collaborative efforts of GBHP and the Belfast Health and Social Care Trust, reflecting a shared commitment to delivering exceptional healthcare infrastructure.
QUIET TRANSFORMATION FOR ICONIC BOYS’ SCHOOL
Architect firm Hawkins\Brown has completed a transformative redevelopment at the Central Foundation Boys’ School, the 150-year-old, top-performing comprehensive school in central London.
he vision was to rationalise and consolidate the school’s several buildings into a cohesive design to allow more efficient use of the campus. Works included providing a new, purpose-built science building equipped with stateof-the-art facilities along with a new three-court, multi-use sports hall with changing facilities. The tight nature of the site meant that the sports hall was sunken under the courtyard with rooflights bringing in natural light. It has been designed to comply with Sport England guidance, providing the school with a flexible multi-purpose space that can be used for out-ofhours community activity.
To help combat the problems of poor acoustics and sound reverberation in the sports hall, music and drama rooms, Hawkins\Brown specified Troldtekt acoustic panels across all the ceilings. Panels were chosen in both grey and natural finishes to provide a discreet look whilst complementing the interior design. Troldtekt solutions excel at providing acoustic comfort with a visually-attractive, aesthetic tactile surface along with high durability and low-cost lifecycle performance.

URBAN LABS: FOSTERING INNOVATION THROUGH COLLABORATIVE DESIGN
A booming life sciences sector in the UK is fuelling demand for more high-quality lab facilities in central urban areas. Traditionally, the reserve of rural settings with large campuses, many in the industry are now beginning to understand the distinct benefits that urban locations can offer. Minimising researchers’ travel time and costs, urban labs both attract top talent and embed a culture of innovation into city fabrics – making science and technology more accessible and equitable, say Tim Fry, Director at Arup, and Eve McLoughlin, Centre Lab Manager at the Sainsbury Wellcome Centre at UCL.
There are also significant economic benefits. In a 2023 study 1, British Land and Savills predicted that if the life science hubs in London, Cambridge and Oxford kept up with their US counterparts, by 2035 there would be an additional £4bn annual economic output in the UK, with 67,000 more high-skilled and high-wage jobs.
Yet, while moving labs into cities has clear advantages, it is not without its challenges. Space-poor urban areas are not only more expensive, they also lack large empty spaces that are suitable for science centres. This is a unique challenge for the design industry, requiring engineers to rethink the way we approach the design of lab spaces so that creative solutions can be developed to meet the criteria of individual locations.
The Sainsbury Wellcome Centre (SWC) in central London, which specialises in neuroscience research, is a prime example of an urban lab space built to work for scientists. From the project’s inception, SWC scientists worked hand in hand with Ian Ritchie Architects and Arup engineers to optimise the building for their unique research needs. Since opening in 2016, it has been used for a myriad of purposes, from dry lab spaces through to immersive behavioural experiments.
Essential learnings can be taken from this project. It shows the value of adapting existing buildings and collaborating with scientists from the outset to construct spaces that are tailored to specific needs, yet flexible enough to serve the industry for years to come.
Structural solutions to unlock sustainability
City space is increasingly limited and expensive, requiring all industry actors to approach structural solutions holistically, prioritising longevity and adaptability for future use. Minimising the energy consumption of buildings remains at the forefront of all conversations as we strive for net zero, especially within the science and technology arena. Research is currently underway to solve the challenge of creating an all-electric lab design to maximise efficiency while maintaining strict environmental controls.
The requirements of urban lab spaces can be more complex and hypersensitive than others, with embodied carbon and energy wastage reduction needing to be approached innovatively and with cross-sector
collaboration. These considerations must be undertaken in conjunction with maintaining safety standards and the requirements of the spaces; for example, the specific vibration performance needed for different scientific instruments and experiments.
The SWC is an example of the benefits of embedding sustainability from the start of a project. For example, given many of the SWC labs need 24/7 operation, the team invested in occupancy-based ventilation where possible to reduce energy wastage. Vibration engineering was also at the forefront of the building’s design, requiring extensive analysis and research to develop and deliver the facility’s optimal design solution –combining base structural performance with the integration of active isolation tables.
Tailored design that remains flexible
Each lab at the SWC is unique and requires specific individual environmental controls. Open floorplans were embedded to reconfigure equipment and set ups for each experiment. In urban areas, this presents a particular challenge as space for expansion is limited.
For the SWC, this meant creating interdisciplinary workspaces, as encouraging collaboration across teams was a key priority. To do this, the team implemented circulation routes that promote interaction, as well as open communal areas and lab spaces, while
still ensuring pockets of privacy for focused tasks when needed. And due to experimental neuroscience research requiring low lighting, with staff often working in isolation, the design needed to counter this with natural light in the communal areas and outdoor spaces.
Neuroscience research methodology is constantly evolving, meaning any labs built today need to be able to adapt easily to accommodate bespoke research set ups, and even be flexible to technological advancements not yet developed – a huge and complex feat requiring deep collaboration. This was one of the most challenging aspects of designing the SWC but, by consulting scientists throughout the process, the team was able to plan for future needs of the space, accommodating for the next generation of innovative science.
The SWC is already reaping the rewards of this process, as it is now looking to build more office spaces in the building, having grown to incorporate more research software engineers and computational researchers than originally envisioned. It has also created a new neuroinformatics team to work with experimentalists to develop bespoke tools for analysing and modelling neuroscience data. As the building was structured in the most agile and flexible way possible, the team has been able to adjust to this new format easily, ensuring the SWC can continue to evolve in step with scientific advancements.
Building with scientists, for scientists
The SWC provides essential learnings for constructing lab projects in urban environments, which is still such a new and challenging phenomenon. The unique requirements of these buildings make it even more important to ensure the process is as collaborative as possible, consulting with those who will actually be using the space. Only by bringing architects, engineers, scientists and researchers together can we create responsive, cutting-edge lab environments that will drive tomorrow’s breakthroughs. We must also take this opportunity to foster innovation in the construction industry, driving us to discover new and creative ways to solve complex challenges related to people, planet and place. The economic and scientific potential of investing in these projects is enormous; highly-skilled researchers thrive on the collaboration opportunities that cities provide and our scientific knowledge as a society benefits as a result.
ANALYSING THE NEXT LEVEL FOR THE UK CAR PARK INDUSTRY
There are an estimated 6000 multi-storey car parks (MSCPs) dotted around the UK, with some dating back as far as the early 1900s. A standard and well-used part of modern Britain, these facilities have slowly had to adapt to the evolving needs of drivers and surrounding areas.
Now, the discussion of where car parks will head in the future, how they are constructed, repaired and maintained has become more relevant than ever as the need to consider the changing requirements associated with larger vehicles, electric vehicles, fire safety and aged/sensitive structures increases. With more than 30 years’ experience in the sector, Adrian Baker, Associate at multi-disciplinary consultancy Pick Everard, weighs in on the conversation. Car parks rarely make headlines. The external structures remain largely untouched and unchanged from when they were first built and, instead, simply become another part of the skyline in their location. The intensity and damage caused by the Kings Dock MSCP fire in Liverpool in 2017 was an exception, creating headlines and starting the debate about how car park fires start and how design and materials used in construction could contribute to fire spread. Last year’s fire at the Luton Airport MSCP served as a further reminder
of the risks and issues that still surround such structures.
A less newsworthy but equally relevant issue relating to car park design, usage and safety is the size and weight of modern cars. The emergence of electric vehicles adds further to this, having implications in respect of both weight and fire. It is, however, noted at this point that neither of the car park fires noted above were started by electric vehicles.
The issue of monitoring and maintaining aged structures is no less important than it has been since the partial collapse of Pipers Row car park in 1997. This instance saw a 120-tonne section of its top deck collapse, luckily causing no injuries despite the car park being in use at the time. However, with the continued increase in weight of modern vehicles over recent years, there is no doubt that weight and load considerations have continued to compound. These evolving issues resulted in the IStructE starting a review of existing
design guidance in 2020. This led to the publication in 2023 of the IStructE Car Park Design Guidance Report, which made recommendations for the design and operation of car parks to meet changing and future needs – revising best practice guidance at a time of great change.
Its publication represents a defining moment in the design and construction of MSCPs, in a similar way that the partial collapse of Pipers Row resulted in the publication of the ICE Recommendations for the Inspection, Maintenance and Management of Car Park Structures.
Regulations and recommendations
Fire safety requirements contained in Building Regulations Approved Document B are intended primarily to ensure the structure retains its integrity long enough for persons to evacuate. Subject to height and ventilation limitations, this is generally for 15 minutes for the main car park structure.
Unsurprisingly, on the back of the Liverpool and Luton examples, the IStructE recommendations, in respect of fire safety, represent the greatest divergence from existing requirements and regulations, ranging from 60 to 90 minutes depending on the height of the car park. It does, however, note that a riskbased approach should be adopted, which should consider construction type, details and fire-fighting options that could reduce the recommended fire resistance.
Appropriate advice and guidance on these issues would assist in delivering the best value option, including on the increased risk posed by electric vehicles and how they burn.
The uniformly-distributed imposed load provided by BS EN 1991-1 is 2.5KN/ m2, with the IStructE recommendations being to increase to 3.0kN/m2. While this can be incorporated when designing new MSCPs, it is more problematic on existing and potentially dilapidated car
parks. There has been some concern about this issue in the national press but it is, again, something that, with the appropriate level of experience, can be managed and de-risked.
While these are primary areas of concern when it comes to changing car park use, they are not the only matters to be considered. The decision for asset owners on any of these should be an informed one, involving consultation with industry experts.
At Pick Everard, this is something we have advised clients on, and we continue to monitor changes in car park safety that may impact them. One such situation involved a client looking to enhance the car park structure to provide for two-hour resistance, which essentially requires the use of more concrete. We supported the client with a full risk-based approach that delivered the bestvalue solution to the satisfaction of all stakeholders – including insurers.
Rising challenges
One of the options for car park operators is to support EV charging as an upgrade option, with the rising ownership of these cars. The difficulty comes with the availability of power and assessing the supply options. Many car parks won’t have the capacity to support large numbers of chargers without this, but, of course, this is a large initial investment. Pick Everard have extensive experience of advising clients on installation, funding and management options.
Other options we are involved in is the conversion of car parks into commercial charging hubs, which would benefit from the investment in the long term at the same time as addressing under utilisation issues.
In our own work, we are able to assess alternative uses for the future, and identify where costs will be incurred. It’s essential to have a good analysis of the environment to understand how the area is being used, because there is no onesize-fits-all solution.
Meanwhile, upgraded equipment is also helping drive revenue increases for car parks. Ticketless parking allowing for ease of use, enhancing efficiency and improving user experience. ANPR installations ensuring reduced non payment and optimising revenue.
Converting lighting sources to controlled LED is also a way of reducing energy usage costs and emissions. A national rollout for a national car park operator comprising the installation of 12,000 lights will deliver a return on investment within 18 months.
Antisocial behaviour is becoming an increasing issue in certain car parks and cities. We have experience mitigating the issues through a number of means, including CCTV and access control, which, through the experience of particular specialist suppliers, we can facilitate at the lowest possible cost.
Lifecare planning
When we consider how long many of the UK’s car parks have been standing, it’s becoming increasingly important for both new buildings and existing structures to consider the full lifecycle. This not only enhances affordability for public sector clients but also supports a sustainable model for the industry.
It is also a requirement of the ICE Recommendations for the Inspection, Maintenance and Management of Car Park Structures that lifecare planning is critical in enabling “the parties involved in the management of a car park to discuss, agree and formerly record those considerations and actions that are essential for the effective, safe and economic management of the structure”.
Any owner or operator that does not have such a plan in place, particularly in respect of aged and sensitive structures, would be exposed should there be some issue or failure with the structure. That’s why working with consultants with unrivalled experience in lifecare planning, maintenance and repair feasibility works – like Pick Everard – is critical to ensuring the continued, safe operation of potentially sensitive structures into the future.
GAME-CHANGING ACOUSTICS: HOW TO ENHANCE THE SPORTS EXPERIENCE THROUGH SOUND MANAGEMENT
Noise control in sports halls and leisure centres is frequently neglected, but poor acoustics can significantly affect the health, wellbeing and enjoyment of users. Ben Hancock, Managing Director at Oscar Acoustics, explains why acoustic treatment is essential for sports performance – and how it can enhance the experience as a whole.
The role that sound can play in the quality of indoor environments is well documented. The wellbeing and comfort of individuals can depend heavily on room acoustics, particularly within hustling, bustling settings. It’s the reason why many forward-thinking asset owners and building managers are now investing in acoustic solutions for areas such as openplan offices and restaurants to safeguard occupant wellbeing.
That said, despite their tendency for high volumes of noise, leisure spaces, such as sports halls and gyms, often fail to receive proper acoustic management – making them uncomfortable and sometimes overwhelming spaces to spend time in. In fact, without due care and attention to acoustic management, indoor sports and leisure facilities can quickly raise stress levels. The combination of large, open spaces, fast-paced activities and noise generated by users and machines
creates an ‘echo-chamber’ effect. In a room containing many hard surfaces, it can significantly amplify sound levels caused by prolonged reverberation. The result can be loud, distracting and unbearable for some. Importantly, it takes them away from the joy of the moment whilst becoming a deterrent for future sports activities.
For teachers, gym instructors or personal trainers, this also makes their job nigh on impossible. The constant need to shout above noise can lead to unwanted stress and a strain on the voice.
Long-term health issues may also occur; persistent exposure can cause tinnitus, chronic hearing loss and even strokes. A student’s performance in that lesson and other subjects will also be impacted if they have difficulty hearing or understanding instructions given by PE teachers.
The good news is that acoustic solutions are available that facilitate effective noise control – making it easier for teachers and
instructors to be heard without taking away from the atmosphere of a lively game or activity. Premium acoustic sprays, for example, offer an ideal solution for indoor sports facilities. By absorbing sound energy rather than reflecting it, reverberation times can be considerably reduced, making spaces more comfortable.
This type of acoustic solution can be applied to almost any surface, which makes it ideal for a wide range of interiors and layouts. However, for those working with school sports halls, the spray must be BB93 (Building Bulletin 93) compliant. This ensures it meets the acoustic performance standards of UK schools and addresses issues such as sound insulation, reverberation times and indoor ambient noise levels. It also helps governing bodies and local authorities to ensure learning environments are acoustically suitable for their intended activities.
Yet, there’s more to premium acoustic sprays than just sound management benefits. As Building Regulations around sustainability become more stringent, these sprays can also contribute to various sustainable design and health certification systems, including BREEAM, SKA, Living Building Challenge and can add up to 17 points towards a project’s LEED (Leadership in Energy and Environmental Design) rating.
Fire safety is another critical consideration for fitness facility managers. It’s essential to select acoustic sprays with third-party testing and safety certifications. Opting for sprays that exceed the Approved Document B fire requirements (Class 0 to BS476 and B-s1,d0 fire rating) ensures enhanced safety. In the event of a fire, these sprays produce minimal smoke and no droplets, aiding in the safe evacuation of the facility.
What’s clear is that the importance of acoustic health can no longer be ignored.
With growing awareness of health and wellbeing, enhancing acoustic quality in sports and leisure halls is essential.
Better acoustics create a calmer, healthier and more relaxing environment for attendees and staff. Plus, for leisure centres and gyms facing high maintenance and operating costs, prioritising the satisfaction and health of loyal customers is a must.
Investing in effective acoustic solutions is, therefore, not just about reducing noise –it’s about enhancing the overall experience. By tackling excessive noise, sports halls and leisure centres can truly elevate performance levels and the wellbeing of everyone involved.
NEW VIDEO HIGHLIGHTS BENEFITS OF PARTNERSHIP APPROACH TO FIRE SAFETY
A video produced by a Siemens Building Products partner illustrates the importance of manufacturers and installers working closely together to realise the optimum solutions for protecting buildings from fire threats. Diamond Systems is a Belfast-based company that has specialised in life safety and security systems for almost 40 years. It is a second-generation family business and has been partnering with Siemens since April 2013. Joint MDs Angela Bennett and Stephen Snoddon wanted to celebrate that partnership and decided to create a video that provides an overview of the Siemens systems they offer and how the two companies work together to achieve maximum fire safety for building owners and operators. The video focuses on the two main systems manufactured by Siemens: Cerberus Fit for small- to mediumsized premises and Cerberus Pro for larger applications. Stephen talks of the range of benefits to installers, including features such as the line tester tool through which cables can be tested before the commissioning process can start, pinpointing any open or short circuits and any earth faults. The video can be viewed on Diamond Systems’ YouTube channel.

NUAIRE RELEASES CPD ON HIGHTEMPERATURE AXIAL FANS AND VSDS
Nuaire is pleased to announce its latest CPD, which addresses high-temperature axial fans and variable speed drives (VSDs). It has been introduced to clearly explain the standard ‘BS EN 12101-3:2002 Smoke and heat control systems – Specification for powered smoke and heat exhaust ventilators’. Simon Plummer, Nuaire Axial Divisional Manager, has written the CPD. “Frequency converters have been permitted for use during a fire event since 2015, enabling dual-mode fans to be controlled by VSDs, even during fires. Before this, the VSD had to be bypassed during a fire event, with the fan running at 100%. However, there remains confusion about how high-temperature fans and VSDs can be certified and used for various smoke applications. Our CPD addresses this, explaining the standard in detail and the flexibility it offers consultants and smoke designers.”

With growing emphasis on managing the risk of smoke and fire within building safety, Gilberts is leading the way to optimise control. To address increasing demand and exceed criteria laid down in the latest Building Regulations, Gilberts is launching a new, fully-tested range of insulated smoke and fire dampers. The insulated dampers complement Gilberts’ established Ductgard units for HVAC ductwork. The insulation element of the new dampers helps minimise the risk of heat transfer and thus the risk of fire spreading beyond the compartment. Its performance exceeds the two relevant layers of fire safety in buildings: Integrity of compartmentation and structural safety. Spring and thermal fuse activated, the insulated dampers offer fire resistance of EI30, EI60, EI90 and EI120 for general ventilation systems with walls and partitions of various ratings. Thus, they deliver effective cut-off partitioning between the fire-engulfed zone and the remaining part of the building, helping maintain the building’s integrity. The range is fully tested and certified to EN 15650, EN 13501-3 and EN 1366-2. The introduction of the insulated dampers builds on Gilberts’ 60+ years’ heritage of bringing to market advanced technology that enhances the design, safety, energy efficiency and occupier comfort of non-domestic buildings. All Gilberts’ products are designed and developed in accordance with BS EN ISO 9001:2015 quality standard in the company’s state-of-the-art 140,000ft2 facility in Blackpool.

REVOLUTIONARY
SFS Group Fastening Technology and Kingspan Insulation have pooled their respective expertise in rainscreen cladding support systems and insulation materials to launch an optimum performance solution offering A2-s1,d0 reaction to fire, presenting the potential to optimise envelope design on buildings of any height. The NVELOPE NVS-RP range of stainless-steel brackets has been developed specifically to retain Kingspan’s latest insulation development – Kingspan AlphaCore panel silica-based insulation, which offers a thermal conductivity of just 0.020W/ mK, with a Euroclass A2-s1,d0 reaction to fire. The slimline material is available in thicknesses of 20, 25, 30, 40 and 50mm with a weight ranging from 3.6 to 9.0kg/m2. AlphaCore Pad is also water repellent. Crucially, the combination has the potential to create far slimmer facades, which will withstand the weather as well as optimise energy performance. This is because, instead of compromising AlphaCore Pad’s thermal performance with multiple fixing penetrations, SFS has completely reimagined established components from its NVELOPE system to absolutely minimise cold bridging.

ROCKWOOL RELEASES TECHNICAL BULLETIN
ROCKWOOL has released a technical bulletin announcing the results of an independent study into the impact of gaps in the insulation layer and their effect on thermal performance. 10 samples of stone-wool insulation of various densities were tested to ISO 8301:1991 ‘Heat flow meter apparatus’ and BS EN 12667:2001 ‘Thermal performance of building materials and products’. The tests were conducted in accordance with BS EN 13162:2012+A1:2015 ‘Thermal insulation products for buildings’. Highresolution Scanning Electron Microscopy (SEM) demonstrated that when two separate slabs are tightly joined, the gap between them closes, and the individual fibres knit together to form a continuous network of fibres containing trapped pockets of air.

REDEVELOPMENT IN ROCHDALE
Rochdale Upperbanks is a regeneration project on a formerly disused brownfield site delivered by Rochdale Development Agency on behalf of Rochdale Borough Council, with Willmott Dixon acting as the main contractor. The scheme comprises 242 studio, one- and two-bed apartments with balconies, housed in two nine-storey apartment blocks and a 146-room Hampton by Hilton Hotel. Because the buildings are higher than 18m, the materials used in the facade had to be non combustible, in line with Approved Document B (ADB). This project commenced before further statutory guidance was introduced to ADB in December 2022 for residential buildings (purpose groups 1 and 2) above 11m. Aiming to optimise energy efficiency and create a healthy environment for the buildings’ occupants, an ambitious thermal performance target of 0.15W/m 2K was also set. The architects specified more than 5000m 2 of ROCKWOOL insulation for the whole facade system. RainScreen Duo Slab is a stone-wool insulation product specifically developed for use within ventilated cladding systems and sealed systems such as curtain walling. Other ROCKWOOL products installed included RWA45 and Soffit Slabs.

Changes to fire regulations across the UK and the challenge of showing compliance with them are motivating a growing number of construction professionals to book a place at FIREFLY’s highlyinformative CPD. The 60-minute presentation, ‘The Design and Understanding of Passive Fire Protection and Compartmentation’, introduces fire behaviour and the distinctions between active and passive protection measures before explaining the various ways in which fully-compliant compartmentation can be achieved.
WEST FRASER’S FLOORING IS FINE COME RAIN OR SHINE
West Fraser’s P5 particleboard is available in two versions: CaberFloor P5 and CaberDek. The difference between them is that the latter’s top face is protected by an ultra-tough peel-clean layer. Both boards are produced in 18 and 22mm thicknesses, measuring 2400 x 600mm, with T&G joints along all four edges. The total length of time for which the installed floors can remain exposed to the weather generally leads customers to choose between CaberFloor and CaberDek. Despite the inherent moisture-resisting qualities of the standard P5 particleboard, CaberFloor should not be left exposed to rain for any prolonged period. For CaberDek, however, the safe period extends to a full 42 days or six weeks, not only withstanding rain, snow or ice but also creating a safe, non-slip surface.
PYRAN® S
For fire resistance and protection of people and property
Now available for UK manufacture
Multifunctionality in fire protection
PYRAN® S is a pre-stressed, monolithic borosilicate single pane safety glass in accordance with EN 13024-1.
As a component in fire-resistant glazing that meets the requirements of resistance classes E 30, E 60, E 90 and E 120, it has proven its outstanding optical and mechanical characteristics over the years in a wide variety of buildings.
Areas of application
PYRAN® has been internationally approved and ideally suited for:
• Facades
• Partition walls
• Skylights and rooflights
• Doors
• Roofs
• Smoke screens
• lift door glazing
• lift shaft glazing
Facts
• Higher ability to withstand temperature differentials: In comparison to soda-lime glass, tempered borosilicate glass can better withstand temperature differentials and can therefore be glazed with normal edge covers (20±2 mm).
• Higher softening temperature: Because the glass is selfsupporting for more than 30 minutes, large panes and simple frame constructions are now possible.
• Higher viscosity: The glass flow rate is low due to the high viscosity and durability of borosilicate glass, so with more edge cover, greater fire resistance times in excess of 90 minutes can be achieved.
• NiS crystals do not form: Due to the chemical composition of borosilicate glass, nickel sulphide crystals cannot form. Spontaneous glass fracture due to embedded NiS crystals cannot happen with PYRAN®.
