The success of the UK’s energy transition will rely on collaboration between businesses to maintain a robust supply chain, a global energy specialist has warned following the launch of its latest research. Aggreko has revealed in its latest report Rebalancing the Energy Transition that CEOs in the UK cite supply chain main risk to the energy transition, followed by lack of investment and access to technology. This concern over the impact of supply chain comes as the UK government has reaffirmed its commitment to renewable energy production and infrastructure through the establishment of Clean Power 2030. The new initiative is aimed at overcoming barriers and accelerating progress on energy projects, including the recent plans to give approval power for onshore wind projects over 100MW to government ministers[1] over local authorities. Clearly, successful rollout of infrastructure for renewable energy production and transmission, along with the energy transition of businesses across the UK, will require innovative ways of thinking within the energy supply chain. Aggreko’s research showed that ambition around the energy transition among energy intensive businesses is also strong, with eight in 10 UK CEOs stating they will increase investment in the energy transition over the next 12 months. Though nine in ten (or 9 in 10) UK respondents cited they have adjusted timescales around energy transition targets, the UK has the highest proportion of CEOs (52%) across the countries surveyed that stated they have only adjusted short term goals and remain on track for net zero targets. With ambition from businesses matching that of the government in terms of sustainability targets, Aggreko is highlighting how the entire supply chain must work together to ensure a successful energy transition. Alan Dunne, UK and Ireland Managing Director at Aggreko, said: “With continued uncertainty around energy cost and resilience, businesses in the UK are facing the challenge of balancing profitability and sustainability. Much like the government and its Clean Energy 2030, UK businesses remain ambitious in making their energy transitions. However, our research has found that barriers and challenges still remain, even though the ambition to fund the energy transition is there. “High energy costs and fluctuating energy security and resilience has continued to be a challenge for businesses, however, supply chain issues are clearly the biggest risk posed to energy transitions in the eyes of leaders. To overcome all of these challenges at once, it is imperative that businesses engage with expert partners across the supply chain to identify practical ways to reach ESG goals while keeping operations efficient and profitable.” As the UK continues to develop renewable energy production and infrastructure, the report highlights the challenges around striking the right balance between commercial and ESG ambitions with energy procurement. A key part of this is working closely within the energy supply chain to assess requirements and challenges to choose the most practical solution to deliver efficiency and environmental benefits. Providing the latest efficient technologies through its Greener Upgrades portfolio, such as battery energy storage solutions and Stage V generators, is a central part of Aggreko’s sustainability framework Energising Change Dunne continued: “Making a success of the energy transition relies heavily on businesses having the right technologies and solutions for their requirements, along with the expertise to implement it correctly. While reliable energy supply and stable costs remain in the balance for the UK, working with expert energy supply partners can provide businesses with this to provide resilience and cost efficiency throughout the energy transition.” For more information and to read Rebalancing the Energy Transition, click here.

Some projects require military style planning to ensure that work can be undertaken in short periods of access time, and this is absolutely the case at Milton Keynes Hospital where Ashe has been working on a £3.4m Salix funded project for Milton Keynes University Hospital NHS Foundation Trust (MKUH). In order to meet efficiency targets the hospital building, which was constructed in 1984, needed to replace its single glazed windows with thermally efficient double glazing. Many of the windows are on occupied hospital wards each with eight beds. Without the capacity to decant an entire ward to another space, the project has been undertaken in live wards with only the patients from the two beds nearest the windows being relocated during the works. Window of opportunity Contracts manager, Steve Cockram, explains the challenges on a project of this type: “We only got one day to cordon off each area to the safety and hygiene standards required by the hospital which takes around two hours. We then removed the existing windows, installed the new windows, clearing any debris and cleansing the area to high clinical hygiene standards ready for patients to move back into the bay by the end of the day.” A major challenge was upgrading the windows in the hospital’s shop. The shelving and refrigerators were all positioned against the windows which had to be moved from the working area, old windows removed, new windows installed, then all returned to their original positions, in one working day, whilst the shop remained open to the public. Steve continues: “Despite the best programming, it was inevitable that some wards would not be available as planned due to emergencies, therefore it was decided that all of the new windows would be ordered and stored within easy access of the site so that we could pivot quickly to work in another part of the building should access be denied.” This plan B approach made Ashe so efficient that the team actually shaved four weeks off the original schedule which was due to complete in mid-October. In total 456 windows, 22 doors and a curtain wall have been installed. Precision timing Extensive mechanical and electrical works have also been carried out providing new energy efficient air handling units (AHU) to ensure clean ventilation. The AHUs serve four of the main operating theatres at the hospital, so timescales were crucial in achieving theatre re-commissioning. The trust required three months’ notice for the start of the works to allow for closures to be communicated to staff, and operations to be scheduled appropriately. Each theatre was shut down for three weeks at a time, with the handover of each AHU and theatre allowing access into another theatre. Ashe adhered to these strict timescales and managed to complete the AHU works to operating theatres also ahead of programme. Ashe has also installed the services in preparation for the upgrade of the steam generation for the hospital’s autoclave sterilisation system. The works will enable the hospital to transition from gas-powered to an electrically-heated system, to make it more energy efficient. Careful co-ordination with the hospital was required so that one of the four main entrances could be closed for two days to allow use of a crane to access the plant room. Signage and barriers also had to be of a high standard. The project forms part of the hospital’s Greener Future plans having secured £4.8m of funding from the Government’s Public Sector Decarbonisation Scheme which aims to reduce emissions from public sector buildings by 75%. The project was procured under the Pagabo Medium Works Framework. This is one of several healthcare projects Ashe is currently undertaking which includes creating a new community diagnostic centre in the heart of the city, for MKUH.

The project is also committed to working alongside local businesses and residents, creating contract opportunities and integrating community input into every phase of development. The company is collaborating closely with the Isle of Anglesey County Council, Holyhead Town Council, and other stakeholders to ensure that the project aligns with community values. “This is a sensitive and significant development,” said Council Leader Gary Pritchard. “It’s reassuring to see a commitment to local employment, sustainability, and the protection of the Welsh language.” Sustainability at the Forefront Responsible development is central to the project. The Seventy Ninth Group has pledged over £1 million to local initiatives, ensuring the scheme addresses community and environmental priorities. Local engagement sessions will be held throughout the development, providing residents with opportunities to contribute feedback and shape the project’s direction. In addition to respecting the natural environment, the group plans to actively enhance it. Measures include the preservation of native wildlife habitats and the incorporation of eco-friendly building techniques. “We aim to develop a world-class destination while protecting the environment for future generations,” said Webster. Completion Timeline and Vision for the Future Construction is expected to take five years, with the first lodges ready to welcome visitors by summer 2025. By then, Penrhos will not only serve as a holiday retreat but also as a symbol of harmonious growth—one that respects the cultural and environmental fabric of Holy Island. David Webster, Chairman of the Seventy Ninth Group, echoed this sentiment: “This is our largest project to date and reflects our vision of delivering high-quality, sustainable developments. None of this would be possible without the trust of our clients and investors, who share our belief in the UK’s potential as a global tourism hub.” As the Seventy Ninth Group embarks on this transformative journey, it is clear that the Penrhos development will leave a lasting legacy—not just as a premier holiday destination, but as a beacon of sustainable and community-led progress.

The Centre is due to open in 2028, marking 100 years since the discovery of penicillin at St Mary’s by Sir Alexander Fleming. The other shortlisted teams invited to take part in the design phase of the competition were: Stanton Williams’ concept design for the Fleming Centre embraces the heritage of its proposed location on the site of The Bays. These former industrial warehouses, dating back to around 1850, were originally used for transport and distribution before being incorporated into the hospital in 1983. Their approach retains and adapts The Bays as a vital link to Paddington’s industrial past while inserting new elements, including the Fleming Discovery Centre, to showcase cutting-edge science and research. The design prioritises sustainability, proposing features such as renewable energy systems, including a water-source heat pump and photovoltaic panels, alongside biodiverse landscaping and a low-carbon structure. Public engagement is central, with the ground floor designed as an open and welcoming extension of the public realm, offering views into laboratories and curated exhibition spaces to bring science to life. Professor the Lord Darzi, Executive Chair of the Fleming Initiative said: “Stanton Williams has a bold vision for the Fleming Centre and have brought our ambitions to life with a concept that reflects the Centre’s unique purpose and global significance. By providing a flexible space to unite researchers, policymakers, clinicians, behavioral experts, commercial partners and the public in the fight against antimicrobial resistance, we can ensure that the Fleming Centre becomes a global beacon for change in healthcare.” Professor Tim Orchard, chief executive of Imperial College Healthcare NHS Trust, said: “This is an exciting milestone for the Fleming Centre and the planned, wider redevelopment of the St Mary’s Hospital site. The Stanton Williams design concept gave the selection panel great confidence that the building they design will honour both Sir Alexander Fleming’s legacy and our aspiration for continued innovation with local and global impact.” Imperial President Professor Hugh Brady said: “The Fleming Centre will bring together Imperial’s world-leading researchers with diverse UK and international partners, including from academia, the pharmaceutical industry, policy community and civil society to tackle the challenge of AMR head-on. The new building will also be a key part of the Paddington Life Sciences development and Imperial WestTech Corridor vision.

Thames Water has appointed Barhale to carry out the £11.6M East Putney Zone Calming scheme, improving water network resilience for customers in the capital. The project will upgrade the pumping and electrical equipment at the Park Lane pumping station in central London. Four pumps will be upgraded: one each supplying water to Putney, Barrow Hill and Shoot Up Hill, and a standby able to supply water to all three locations. Civil engineering, infrastructure and tunnelling specialist Barhale will replace all four of the existing, high voltage pump motors with low voltage, variable speed models that will allow Thames Water to operate the network at a reduced pressure. This will fix pressure issues, and the likelihood of surges of water in the system, which will reduce the risk of bursts and leakage, particularly in East Putney. Barhale will also upgrade the electrical control systems; install new flow control monitoring; replace the existing ventilation within the pumping station with a fully redundant and resilient design; carry out an overhaul of the lighting and water services; and remove all redundant equipment. Shane Gorman, Barhale’s Water Director – Southern, explained the importance of the work and highlighted the operational challenges. “The successful delivery of the East Putney Zone Calming scheme will be a step-change for operation of the water network at Park Lane,” he said. “Replacing the existing fixed speed motors with variable speed motors will transform control of water pressure within the tunnels. For customers, this means a more resilient network and it will significantly reduce the likelihood of leakage. “It is fair to say that there are certain logistical challenges. The site is literally in the middle of Park Lane, one of the busiest thoroughfares in London, with three lanes of traffic flowing either side night and day. “It means that work, and particularly deliveries and access to the site, will need to be planned and managed meticulously. We will be drawing on the experience gained at other busy London locations and in collaboration of the local authority, to make sure that operations are conducted as safely as possible and with a minimum of disruption. “We are looking forward to working with Thames Water to deliver this important scheme.” Commenting on the major upgrade, Roselyn Unegbu, Delivery Director, London Non-Infrastructure, Thames Water said: “This investment is essential to upgrading our Ring Main, ensuring Londoners can count on clean, reliable drinking water for decades to come. It will also help us drive down leakage and reduce the risk of bursts.” Work is expected to complete in September 2027. Building, Design & Construction Magazine | The Choice of Industry Professionals
Key announcement set to reduce direct CO2 emissions by up to 90% in line with the Glencar target to reduce Scope 1 emissions by the end of 2025. Glencar, a leading UK based construction company recognised for its past ranking among Europe’s fastest-growing businesses and known for delivering high quality projects across various sectors, most notably in Logistics & Industrial, Life Sciences & Pharma, Data Centres, Commercial, Ports, Film Studios & Leisure and Civils, has today announced its intention to switch to low carbon Hydrotreated Vegetable Oil (HVO) fuel across all active construction sites from the start of the year and going forward. The major move will see HVO to be used across all site set ups, welfare establishments, and on-site power generation across all of its construction sites. Glencar is one of the first contractors specialising in the Logistics & Industrial sector to mandate the switch to HVO across all sites. HVO is a low carbon biofuel typically made by reacting waste vegetable oils and animal fats with hydrogen to create a fuel suitable for use in diesel engines. The switch to HVO will deliver up to 90% reduction in direct CO2 emissions and 80% in other harmful emissions such as particulate matter. The amount of diesel that Glencar uses annually emits over 720 tonnes of CO2 which accounts for the majority of our Scope 1 carbon emissions which the use of HVO is set to reduce. Speaking about the move Glencar Director of ESG James Scott said: “Our transition to HVO is a major strategic step change that will make an immediate difference and impact on our carbon in construction performance. We estimate a reduction in over 90% in our Scope 1 emissions when every construction site is using HVO. We have set ourselves ambitious targets to achieve Net Zero for Scope 1 & 2 emissions by 2025 and 2045 for Scope 3 emissions and this is another important milestone on the journey. We will continue to monitor new technologies and innovation to ensure we are at the forefront of clean and efficient sustainable solutions. The switch to HVO will also give us further confidence in our emissions data that will enable us to track our reductions and performance against our ESG goals, with the knowledge that HVO itself is a sourced product that is certified through collection of feedstock, manufacturing and delivery into the UK terminal using the ISCC scheme, and thereafter using the UK’s RFAS scheme. This ensures that all feedstocks are classed as 100% renewable under the Renewable Energy Directive 2. Whilst we recognise the carbon reduction potential of HVO, we are also aware of the environmental impacts of HVO production and will closely monitor the sustainability of our supply chain.

An epoxy repair mortar was used to repair the damaged concrete substrate in a clarifier tank at a Wastewater Plant in the UK. The system achieved a complete cure despite being completely submerged in water due to a rainstorm during the curing period. In this way, the concrete resurfacing epoxy, Belzona 4131 (Magma-Screed), was an excellent alternative to concrete. It enabled the Customer to bypass the serious problems that would otherwise have arisen had poured concrete been used in the application instead of the epoxy mortar. Severely Damaged Concrete in Need of Repair The clarifier tank, 18 metres (59 ft) in diameter, was suffering from severe deterioration on the concrete base. This had been caused by the combined effects of corrosion and abrasion from the scrapers that run around the clarifier, moving sludge to the centre of the tank. The damaged concrete in the tank had led to a loss of efficiency of the scrapers and premature wear of the rubber scraper pads. In addition, this had caused the pumps operating downstream to become damaged by the pieces of the broken concrete which had been sucked downstream with the sludge. Repouring concrete onto the base of the tank was considered as a repair solution. However, this was deemed inappropriate as the bond to the original concrete would be insufficient. Specification of Epoxy Repair Mortar, Belzona 4131 (Magma-Screed) Following an inspection by Douglas Potts, Senior Fields Solutions Engineer at Belzona UK, the epoxy repair mortar, Belzona 4131 (Magma-Screed), along with Belzona 4911 (Magma TX Conditioner), were specified. Belzona 4131 (Magma-Screed) was selected due to its excellent mechanical properties as well as its abrasion resistance capabilities. In addition, as this system can be fully cured in just three days in temperatures of 15°C (59°F), this makes it an excellent alternative to concrete which concrete typically takes around 28 days to achieve a full cure. To accompany this specification, case studies and test data were supplied demonstrating the strength and adhesion capabilities of Belzona 4131 (Magma-Screed) to concrete. This, along with the fact that the Customer had used Belzona technology in successful applications before, further cemented their decision to opt for the polymeric technology. Application of Concrete Resurfacing Epoxy Firstly, the surface was power washed, and mechanically prepared using grinders and scabblers. Next, the clarifier was marked into sections and each section was then conditioned with Belzona 4911 (Magma TX Conditioner), using a stiff bristled brush. Screed rails were then used to set the level of the Belzona 4131 (Magma-Screed). 4,500 kg (9920.8 lbs) of Belzona 4131 (Magma-Screed) was then applied using metal floats to a thickness of 6mm (0.24 in). During the curing process, a rainstorm hit the site and the tank was submerged in water. After the storm, the tank was drained and destructive testing was conducted, with support from Belzona Limited’s Research and Development team, on the patch most recently laid. Other than slight cosmetic damage of surface whitening, the system was found to be fully cured and unaffected. A very different outcome would have been observed had the Customer chosen to use poured concrete for the repair and such flooding occurred. An Alternative to ConcreteThe application and cure was completed in eight days. Had the Customer chosen to use the poured concrete method to repair the substrate, the application and cure would have taken weeks to be completed, rather than days. Thus, by opting for the epoxy repair mortar, this ensured that minimal disruption was incurred to the Plant’s operations.
