YORKSHIRE CONSTRUCTION FIRM SAILS ONTO £415M PORTS FRAMEWORK Yorkshire and Lincolnshire construction firm, Hobson & Porter has landed a place on the largest part of a £415m, five-year design and build framework for ports. Associated British Ports (ABP) has named 11 partner contractors to deliver an ambitious building programme at its 21 ports, across five regions of the UK. The work will be focused on the design and build, as well as construct-only agreements, of buildings at the ports. Hobson & Porter, which operates throughout Yorkshire and Lincolnshire, has been selected for the framework’s Humber region, which covers ABP’s largest port area including Hull, Immingham, Grimsby and Goole. The news follows Hobson & Porter recently securing a place on two new regional medium works YORbuild frameworks, which are expected to account for over £640m of spending over the

next four years. These cover the YORhub east region led by East Riding of Yorkshire Council, and the west region led by Leeds City Council.

These complement Hobson & Porter’s growing portfolio of frameworks including North Lincolnshire Council, Pagabo Medium Works, Efficiency North, Brierley Homes, Lidl and North East Lincolnshire Council. Hobson & Porter has a wealth of experience in industrial, logistics and distribution projects throughout the region, which includes recently extending Ørsted’s flagship £9m East Coast Hub, at the Royal Docks in Grimsby, to create the largest offshore wind operations and maintenance facility in the UK. As a vital part of the supply chains of businesses throughout the nation, ABP’s 21 ports support 119,000 jobs and contribute £7.5 billion to the economy every year, handling approximately a quarter of the nation’s seaborne trade.

BEARD ANNOUNCED AS PREFERRED BIDDER FOR SURREY COUNTY COUNCIL Construction firm Beard is now a preferred bidder for Surrey County Council and has been given the go-ahead to begin work on three new multimillion-pound projects. The three developments are two new children’s homes and a family contact centre that will provide much-needed community services across the region. The total value of the projects is £4.6m and entails three separate builds. The first project is the renovation of a vacant site on Ashley Road in Waltonon-Thames which will create a new children’s home. This redevelopment will ensure some of Surrey’s most vulnerable young people are cared for within a safe environment which provides for their material needs together with emotional support as they transition into adulthood. In addition to the children’s home, there will be a ‘No Wrong Door’ facility built as part of the project, providing emergency and temporary accommodation for residents who require rapid placement. The second project is the £1.4m redevelopment of a site in Epsom into a new children’s home. The project includes the demolition of an

04 Construction UK Magazine - June 2022

existing modular centre and construction of a children’s home to the north of the site. The construction will utilise a Structural Insulated Panel (SIP) system to help make it more energy efficient. SIP panels deliver unrivalled insulation and airtightness, which reduces energy costs over the building’s lifetime. The third project is a £2.1m new replacement family contact centre for young children in Woking. The Shaw Contact Centre will provide a secure setting for family engagements by providing seven contact rooms of varying sizes, facilitating one-to-one meetings and full family liaison sessions. The existing centre will be replaced with a new building which will be a combination of one and two storeys. This is to ensure sufficient internal space while minimising massing and responding to the surrounding character of the area, including the nearby conservation area. The new building will be part one-storey with a flat green roof at the front, and a twostorey block at the rear which will help to break up the built form within their context and maximise the opportunity for ecological diversity.

BRIDGE SECURES ITS LARGEST UK DEVELOPMENT SITE TO DATE Bridge Industrial (“Bridge”), the US-based industrial real estate operating company and investment manager, has acquired its sixth UK development site, in Chadwell Heath, from Be First - the regeneration vehicle for Barking and Dagenham Council. Its largest acquisition to date, Bridge plans to develop 333,000 sq ft of last mile logistics space on the 13-acre, former Muller Dairies site in East London, which will be known as Bridge Point Enterprise East.

The former milk processing plant is situated within a prime London logistics location, close to both the A12 and the Elizabeth Line, which is set to open imminently. Bridge will submit a planning application for 10 new last mile logistics units within the development in the summer this year. Paul Hanley, Bridge’s London Partner, comments: “As with all our developments, the new facilities will provide Class A, highly sustainable and futureproofed space to serve a wide variety of occupiers looking for

modern space, in a perfect location to serve last mile logistics in London and the South East.” Dominic Whitfield, Director in the Industrial & Logistics team at Savills, who advised Bridge on the acquisition, comments: “The purchase of the former Muller Dairies site provided Bridge with an excellent opportunity to acquire another prime London site, ideal for last mile urban logistics. Upon completion of the new development, this should help to provide much needed stock in a critically undersupplied market.” Fidu Property acted jointly with Savills, advising Bridge on the acquisition. The legal representatives were Mishcon de Reya for Bridge and Gowling for Be First.

XPO LOGISTICS PARTNERS WITH VETERANS INTO LOGISTICS TO PROVIDE TRANSPORT CAREERS FOR EX-MILITARY SERVICE PERSONNEL XPO Logistics, a leading provider of freight transportation services, has announced a new partnership with Veterans Into Logistics, a national UK charity that connects transport and logistics companies with military veterans and armed forces service leavers to create pathways to employment as truck drivers.

for walls and windows. New care homes, schools and student accommodation will also become subject to glazing limits, to cut surplus heat from the sun. “The minimum efficacy of general and display lighting in all new non-domestic properties will also rise.” Mr Gill added changes that would apply to existing, as well as future, non-domestic properties included reduced maximum flow temperatures for any new or replacement heating systems.

NEW BUILDING REGULATIONS WILL SOON TAKE EFFECT AND PLANS SHOULD NOW BE WELL ADVANCED, WARNS LEADING EXPERT New Building Regulations will take effect in England and an expert has warned construction sector businesses their plans should now be well advanced. Rob Gill, managing director of Leedsbased building physics engineering consultancy Yonder said the new rules would bring “seismic” changes to the industry. He said: “The updated regulations will apply to new domestic and non-domestic buildings, plus existing constructions which undergo specific types of building work, such as the adding of extensions and installation of certain new materials or technologies. The rules set much higher standards in areas such as energy efficiency, lighting, and heating. Among other changes, they radically alter Part F, which provides guidance on ventilation, and effectively rewrite Part L, which sets standards for energy performance and carbon emissions, for the first time since 2013.” Mr Gill said the only new constructions to which the current rules could continue to apply after 15 June were those for which building notices, initial notices, or full plans had been supplied to relevant local councils before then. But even in these cases he said the concession would be granted to individual buildings, not necessarily whole sites, and only operate if construction work began by 15 June 2023. He explained: “The government sees the new rules as a key step towards achieving

the UK’s goal of net zero carbon emissions by 2050. They’ll compel emissions from new non-domestic properties to be cut by an average of 27 per cent, compared to the position if current regulations were retained.” Yonder’s expertise includes advising construction professionals – such as developers, development managers and investors – on reducing their buildings’ carbon footprints. The company does this through optimising the structures’ use of natural sources, like the sun and wind, for purposes including heating, lighting, and ventilation, for example.

The updated regulations will apply to new domestic and non-domestic buildings, plus existing constructions which undergo specific types of building work, such as the adding of extensions and installation of certain new materials or technologies. The firm is also an experienced assessor of compliance with Part L of the Building Regulations. Mr Gill said: “Important changes the new rules introduce for new non-domestic buildings include higher minimum energy efficiency standards, such as lower U-values

06 Construction UK Magazine - June 2022

He added: “Other requirements affecting existing non-domestic premises include new controls having to be fitted to heating and hot water boiler systems, to improve efficiency, and carbon dioxide monitors becoming compulsory in offices.” Mr Gill said in addition to these mandatory steps for non-commercial buildings, the regulations made certain recommendations. These included the installation of background trickle ventilators and a minimum air supply rate. He said: “With only a month to implementation, the preparation of England’s construction industry professionals for the rules should now be well-advanced. Questions they need to address include not just those about on-site policies and issues but matters going right to the heart of their companies’ management and possibly survival.” Mr Gill said industry professionals needed to consider whether existing suppliers and goods such as materials, fixtures and fittings would be appropriate under the new regime, for example. If not, they should be taking steps to source more suitable replacements and considering how these would be presented to customers. He added: “Construction sector participants also need to answer questions such as how they’ll monitor their own and their sites’ compliance with the new rules, so they can avoid prosecutions by local authorities. “Perhaps most importantly of all, there’s the issue of finance, as it’s likely the changes will generate cost increases, for example, which could be substantial in some respects. Industry players therefore need to gauge now how they’re likely to be affected and take any decisions needed, such as whether it’s feasible and desirable to pass on at least some of the increased prices they may pay to their customers.” For further information about Yonder Consulting, please visit https://yonderconsulting.co.uk/

FIRST FIRMS SELECTED BY BUILDING BETTER TO JOIN NEW £600M CATEGORY 2 OFFSITE DPS Building Better, an alliance of 29 housing associations and councils, supported by the National Housing Federation, has appointed an initial six manufacturers to its new dynamic purchasing system (DPS) for MMC category 2 construction systems. Future Built, LoCal Homes, Project Etopia, Roe Timberframe, Sigmat and Starship Homes are the first

firms selected by Procurement for Housing and Building Better to provide 2D panelised systems, assembled on-site. The DPS is worth £600m over four years and will run in parallel with Building Better’s first MMC framework which launched in July 2021 and covers category 1 volumetric 3D systems. The alliance aims to give members access to a range of different MMC solutions so they can find the right one for their site. Building Better took the decision to create a DPS, not a fixed framework, so panelised manufacturers can join at any point during the term of the DPS. The category 2 segment of the offsite market is evolving rapidly with new products and manufacturers emerging all the time. By setting up a DPS, social housing providers can access the latest solutions and suppliers as they come to market.

MOTT MACDONALD SECURES KEY ROLE ON SUPERTRAM PROJECT Mott MacDonald has been appointed by the South Yorkshire Mayoral Combined Authority (SYMCA) to provide the technical support in the evaluation of options for improving the Supertram system. The newly established SYMCA is looking to transform the South Yorkshire region, achieving significant economic growth, new jobs and reducing income inequality, while moving the city region to net zero carbon emissions by 2040. The Supertram light rail system, launched in 1995, has and will continue to play a vital part in meeting these ambitions, with its renewal integral to the region’s transport strategy. Mott MacDonald has been appointed to develop a renewal strategy and

accompanying business case that will deliver a mass transit network fit for the future for the benefit of local people and the economy. The project will utilise Moata, Mott MacDonald’s digital solutions platform that is able to unlock social, economic and environmental value. It hosts solutions that use the power of data to solve pressing infrastructure problems. It is open, secure, scalable and adaptable, delivering predictive power in a geospatial context through advanced analytics and machine learning. Mott MacDonald’s Buildings and Cities team will use multiple relevant digital offerings including Moata Inspect, Moata Land Management, Moata Carbon Portal and Moata Geospatial.

Over 215,000 homes are managed by the 29 housing associations and local authorities that make up Building Better. Since the launch of its volumetric framework in 2021, alliance members have put nearly 40 schemes through it, getting costs on over 900 MMC homes. With the launch of its DPS, Building Better will help the social housing sector to produce around 5,000 MMC properties by 2026. Manufacturers wanting to join Building Better’s DPS must first be certified by the Buildoffsite Property Assurance Scheme (BOPAS) or assessed by building warranty provider the National House Building Council (NHBC) and their products must aim to meet the Future Homes Standard. Once they have passed an additional selection procedure, looking at their commercial, social and sustainability credentials, manufacturers can bid for opportunities via a tender call-off.

With the launch of its DPS, Building Better will help the social housing sector to produce around 5,000 MMC properties by 2026. This process has been streamlined for social housing providers too, with members receiving a tender template pack and hands-on support from Procurement for Housing.

£25M LIVERPOOL ZERO CARBON PROJECT NEARS COMPLETION A £25m scheme to increase the amount of green energy being used throughout Liverpool has entered the final stages of construction. The project, which is being carried out by renewables expert Statkraft, will see a ‘Greener Grid Park’ built off Lister Drive in Tuebrook. The scheme is one of several projects across the country helping to remove fossil fuels from the UK’s energy supply and maximising the amount of renewable energy that can be distributed through the grid. Construction of the site has been ongoing since 2021, and contractors NRS Group have now finalised all major construction work at the site, with the final concrete being poured at the start of April. This follows the recent installation of two synchronous condensers supplied by ABB. The final stages of development will now see the installation of the supporting components and auxiliary systems needed to deliver the energy to site, with works continuing into late summer. Following a period of testing, the site will be handed over to Statkraft, with operations and long-term maintenance services provided by ABB, whose UK team is based in Warrington. ABB have also been responsible for the delivery and installation of the park’s specialised equipment. The site is expected to be operational in Autumn 2022.

Guy Nicholson, Head of Grid Integration at Statkraft UK said: “Statkraft has invested over £1.4 billion in the UK’s renewable energy infrastructure since 2006, and we’re proud to be involved in a project that’s bringing more reliability to Liverpool’s power supply. “The Lister Drive Greener Grid Park will not only create more opportunities for the city to use green energy but will also contribute to the local economy through jobs and suppliers.” Planning permission for the Lister Drive Greener Grid Park was initially granted by Liverpool City Council in 2020 after National Grid ESO, the operator of the GB electricity grid, identified a need for additional stability services to the Liverpool grid.

Statkraft has invested over £1.4 billion in the UK’s renewable energy infrastructure since 2006, and we’re proud to be involved in a project that’s bringing more reliability to Liverpool’s power supply. The site will mimic the spinning turbines of a traditional power station, providing the high inertia that grid operators rely on to maintain grid stability. As power from renewable sources like wind and solar is fed into the structure, a 67 megavolt amps reactive synchronous condenser, coupled with a 50-tonne flywheel, provide the inertia required to ensure the network frequency and voltage are held stable.

WHY BACKACHE IS A HEADACHE FOR BUSINESSES AND HOW TO HELP AVOID IT It’s not just equipment and materials that are put through their paces on building and construction sites – construction workers are the people most likely to suffer from backache, with over half reporting it to be an issue1. In fact, musculoskeletal disorders (MSDs) are one of the most common work-related ailments reported in Europe, with over 58% of workers reporting they have suffered from at least one2. Not only are MSDs painful for your workforce, they’re also costly for your business. When you consider losses in productivity, production delays, sick leave and even compensation, it’s easy to see how backache can quickly become a headache, explain the experts from Rubbermaid Commercial Products (RCP). So, what can you do to help avoid it?

Understand the risks With research showing that one back-related MSD alone costs a company £14.5K on average3, it’s clear that identifying the risks and taking preventative measures is as essential for promoting health and safety as it is for protecting your business against unnecessary costs. Carrying and lifting heavy workloads are among the key physical factors that increase the risk of your employees developing MSDs. In tough environments where your team are constantly moving materials and waste, your workers are particularly vulnerable. Let your equipment do the heavy lifting Choosing the right equipment for heavy lifting is essential when it comes to reducing the risk of injuries. Using ergonomically designed containers reduces the strain on workers’ backs. With the famed durability and robustness of the original iconic BRUTE®, RCP’s new

Wheeled BRUTE® waste container has been designed with ergonomic features that help users move waste more easily while maintaining healthy posture.

Choosing the right equipment for heavy lifting is essential when it comes to reducing the risk of injuries. With an ergonomic handle that requires less force when moving heavy loads of up to 80kg, the Wheeled BRUTE® helps to prevent users from putting excessive strain on their backs and shoulders by leveraging other muscles. The neutral wrist position allows for comfortable manoeuvrability and control while the kick/tilt plate allows users to tilt the container with their foot, reducing strain on the upper body. The 6” wheels remove the need for dragging, meaning loads can be moved five times more easily4. Implementing preventative measures such as the new Wheeled BRUTE® helps to keep your workforce moving and minimises the future negative impact of MSDs on your team and your business. Famed durability to help you Buy Better, Waste Less Built to withstand the tough demands a job on the construction site throws at them, BRUTE® containers are famed for their durability and waste efficiency, never warping, cracking, fading, or crushing. Since 1968, BRUTE® has helped businesses improve productivity by managing and collecting waste more efficiently and safely. Over 5 decades later, BRUTE® still has your back – quite literally! With a 5-year warranty for extra peace of mind, you can be confident you can Buy Better, Waste Less and support sustainable practices too.

People On The Move The volunteers who took part in the trip with The Abode Project to Uganda outside The Abode Junior School.

East Africa by providing education facilities and medical care as part of a long-term sustainability programme. Ross said: “The people we met out there were amazing. Some of the children had practically nothing but what they did have, they were willing to share. Everyone was happy, even with the bare minimum. It really made us appreciate everything I’ve got at home and made me realise how much we take things for granted in day to day life. “There are around 120 children enrolled in the school, but as the trip was during the school holidays there were only 40 children present when we were there. Those 40 children were all either single or double orphaned and they board full time at the school.

SITE MANAGER ROSS USES BUILDING SKILLS TO HELP CHILDREN IN UGANDA A school in Uganda now has a dedicated special needs centre thanks in part to the efforts of a Northamptonshire building site manager. Ross Jenkins, who oversees construction at Bellway’s Hawthorn Place development in Wellingborough, put his building skills to good use on a recent trip to Kabale in Uganda as part of a team of 46 volunteers taking part in the Abode Project. The 35-year-old, from Northampton, worked to improve facilities at The Abode Junior School, which has 120 children on its roll. His participation in the trip was partly funded by Bellway, which donated £350 and matchfunded the money Ross raised to help him reach his £2,000 target. Ross said: “The work we did at the junior school started almost straight away – we made the framework for two extra classrooms,

and we completed and opened the special needs centre. The completion of the special needs centre was one of the main reasons behind visiting the school and a big reason for me joining the trip in the first place. In Uganda, children with disabilities are often not accepted by society and hidden by their parents in their houses. This centre will give parents somewhere to drop their children off whilst they go to work and will give the children a place to escape – it will make a huge difference to so many people’s lives.” The work carried out during the trip included rendering, digging foundations, bricklaying and carpentry. The group also redecorated the other five classrooms at the school with a fresh coat of paint and some educational artwork. The Abode Project is a non-profit organisation aiming to help children in

“All the children welcomed us by singing songs and throughout the first day we had music playing and had a mini sports day. We did the three-legged race, the wheelbarrow race and played some football – it was a great way to get to know the kids.” Out of the 120 children who attend the school, 100 of them had sponsors before the Covid-19 outbreak, with sponsors paying for their uniform, school fees, food and books, but since the pandemic 80 of those sponsors have pulled out. Ross continued: “These children really need our help. I sponsored a little girl when I was out there but there are so many more children without sponsors. When I got home, I felt a sense of guilt about how much money we waste and how much emphasis we put on things that don’t really matter. You realise there are bigger problems in this world. There is a real sense of community out there, everyone looks out for each other, and I can’t wait to go back.” More information about the Abode Project is available at https://theabodeproject. squarespace.com/.

Graphene-Enhanced Concrete

GRAPHENE-ENHANCED CONCRETE: PIONEERING CHANGE IN CONSTRUCTION By Neill Ricketts Construction output is showing no signs of slowing down as Q1 showed the biggest increase since August last year. The industry has clearly shown it is recovering from the economic storms of the past two years, but what about the environmental implications?

Versarien Lunar 3D printed and made of CementeneTM

The construction industry currently accounts for 40% of the world’s greenhouse gases making it one of the biggest contributors to climate change. The effects on the environment are too large to ignore. As the industry grows, we must find ways to make building practices more sustainable. Decarbonising the construction industry The concrete market alone contributes to 1.5% of the UK’s carbon emissions. The need for eco-friendly building practices is becoming more urgent and has accelerated the pace of Research and Development (R&D) into how wonder materials such as graphene can make construction more sustainable. Materials like graphene can be added to building project plans due to the various benefits they provide. Despite being only one atom (~0.3 nanometres) thick, graphene is 200 times stronger than steel by weight. Once it is added to cement, it can increase the strength of the resulting cementitious composites by 30%.

A recent study conducted by Cambridge University indicated if the addition of graphene results in a 5% reduction of cement, the effect on global warming could be reduced by 21%. These results show a pathway for contractors to utilise advanced materials in building practices to lower the impact of construction on the environment that can be attributed to the introduction of raw materials.

Economic benefits and durability of graphene-enhanced concrete For the most part, construction output is dedicated to new builds- only 40% of it is used for refurbishment and maintenance. This further emphasises the need for durable buildings that do not require as much upkeep. Concrete is traditionally weak in tension. To remedy that weakness, steel is needed to reinforce concrete. Graphenebased admixes significantly increase the tensile strength of concrete, meaning the need for steel reinforcement can be reduced to achieve the same structural performance as normal concrete. A study conducted by the University of Exeter found that including graphene in concrete led to a 50% reduction of the required concrete material while still fulfilling the specifications for the loading of buildings. This added durability means that buildings are more resistant to adverse weather conditions and reduces the need for maintenance. Alongside this, decreasing the amount of construction material required will not only save organisations time on building sites but also save them money. There are estimates that using graphene-enhanced concrete can provide overall cost savings of 10-20% over standard concrete. Applications of electrically conductive concrete There are a variety of applications for a highly conductive material like graphene. The combination of the electric and thermal properties of graphene has recently opened up the possibility of potential applications in underfloor heating. By applying a thin layer of cementitious material containing graphene onto the flooring, the concrete itself can produce heat. While this can offer economic benefits, it can also conserve energy and reduces the impact on the environment.

The addition of graphene to cement means considerably fewer raw materials are needed to achieve the same structural performance. Versarien launches its Lunar lifestyle pods

The same strategy can allow for the emerging application of solid-state heated roads. This use of graphene in concrete for roads will make it easier to clear ice and snow from motorways. Additionally, it can provide safer roads to drive on and save money and time. The future of construction

Looking to the future, as industries commit to reaching net-zero and becoming carbon neutral, the construction industry must play its part in lowering its carbon footprint. With construction output showing no signs of slowing down we must make building materials and practices more energy and cost efficient. Investing in and utilising technological innovations such as graphene will be the way forward if the construction industry is to reduce its carbon emissions.

ELECTRIC HEATING COMPANY: HERE TODAY FOR YOUR TOMORROW A Government initiative launched in April 2022 meant that households will now be offered subsidies of £5,000 to help them make the move to low carbon heat-pumps when their boiler needs replacing. As a result of this news there has been an increased interest in Electric Heating, with many considering it as an alternative to their gas heating. And with the UK setting a target of 2050 to be carbon neutral or net-zero, this interest in Electric Heating systems will continue to grow. Net Zero is a term which has become more prominent and is something that the Electric Heating Company is helping to work towards through it’s innovative electric heating technologies.

Electric boilers can be powered from renewable energy sources such as solar power, which are completely free from CO2 emissions, helping us to move towards the target of net zero emissions.

Governments are working towards a mid-century target of net-zero emissions, this means phasing out traditional heating methods which involve burning fossil fuels.

In the UK alone the government intend to generate emission-free electricity by 2050. In 2020 they pledged 40GW of windgenerated electricity in the UK by 2030. This is enough to power every single household in the United Kingdom.

EHC recognise the growing demand for heating and hot water solutions that are both sustainable and eco-friendly, and we are proud to say that all of our products are designed with this in mind.

When you move to a renewable energy tariff with an Electric Heating system, you are moving to carbon-free heating which contributes to a sustainable and renewable future.

Moving to a renewable energy tariff with Electric Heating means that you’re moving to carbon-free heating which in turn helps towards a sustainable and renewable future.

At EHC we are a customer orientated business. All of our products are designed with both the installer and homeowner in mind. Our product range uses cutting edge technology yet remains user friendly due to our innovative processes. Further to this, we have a reputation for always putting the customer first and as a result have won National Customer Service awards in recognition of this. Also, electric boilers are easy to install as there is no requirement for a flue as there is no combustion process within the boiler. This means the overall cost of the installation is significantly less than other alternatives. EHC also provide Electric Heaters and Radiators which in term offer complete peace of mind for reliability, performance and safety that are available in a host of contemporary styles and outputs. The entire range of Electric Heaters and Radiators are 100% energy-efficient products and are Lot20 Compliant. They are usually installed by qualified electricians or simply plugged in using the 13A UK Plug supplied with the product. We will be attending Installer Live in June and loo The Electric Heating Company are one of the foremost suppliers of electric heating and hot water products in the UK since 2005. Our product knowledge and support is unrivalled in the heating and hot water industry. Pay us a visit on stand K138 at Installer LIVE in June to find out more.

GLOUCESTERSHIRE AIRPORT CELEBRATES COMPLETION OF TRANSFORMATIONAL UPGRADES TO RUNWAYS Gloucestershire Airport, the UK’s busiest general aviation airport, is celebrating the successful completion of major upgrades to its crosswind (04-22) and main (9-27) runways, which involved runway resurfacing, the installation of new runway lighting, upgrades to signs and drainage and new below-ground infrastructure in readiness for a new radar system. The programme of work, which was carefully phased to enable airport operations to continue throughout, was delivered by VolkerFitzpatrick, one of the UK’s leading engineering companies, and project managed by Ridge & Partners LLP. Gloucestershire Airport’s Managing Director, Karen Taylor joined Cotswold Aero Club’s Phil Matthews, one of the airport’s longest-standing tenants, in the first aircraft to take off and land on the newly opened main runway. The airport also welcomed back Little Jet Company’s aircraft from Oxford Airport, where it had been temporarily operating while the upgrades took place. “The successful completion of these upgrades to airside infrastructure heralds the start of a new chapter for Gloucestershire Airport – possibly the single most transformative period in our recent history,” explains Taylor. “Putting the airport firmly at the top end of aviation standards and technology, these vital upgrades elevate the quality and status of the airport and, together with ongoing work to deliver CGX Connect, serve as the catalyst enabling us to actively explore additional revenue streams and realise our long-term strategy for sustainable growth.”

perimeter between the existing Anson and Meteor business parks. Work to allow vehicular access to the site finished earlier this month and completion of the scheme is scheduled for early summer.

The airport currently contributes around £52 million annually to the local economy and plays a key role in supporting significant projects, including cyber development at Golden Valley and Gloucester’s digital campus ‘The Forum’, both of which are now underway.

connectivity to and from national and international destinations and establishing itself as a centre of excellence for all aspects of business aviation, aviation training and aviation-related research”. Kevin Berry, VolkerFitzpatrick Operations Director, comments: “Keeping one runway open while works were underway to minimise the impacts on day-to-day airport operations and the surrounding area was always going to present us with some challenges. We’d like to thank everyone at the airport, as well as surrounding neighbours, for their understanding and cooperation over the last several months – this has all contributed to our delivering the project on time and to budget.” Justin Wright, Senior Project Manager at Ridge & Partners LLP, added: “It’s been really pleasing to work on a project so close to Ridge and Partners’ Cheltenham office. We have enjoyed working closely with VolkerFitzpatrick to deliver the upgrades on time and within budget and we look forward to seeing the sustainable growth these upgrades will help unlock for Gloucestershire Airport.”

Funding to deliver refurbishment of, and improvement to, the airport’s runways was made available by the airport’s joint shareholders, Gloucester City and Cheltenham Borough Councils, in recognition of the important contribution Gloucestershire Airport will continue to make to the region’s economic growth. Taylor continues: “Gloucestershire Airport is a unique and important asset for the county. With these refurbishment works now complete, we have in place the foundations on which to build the airport’s profile as a ‘gateway for growth’ – significantly contributing towards realising the county’s ambition for economic growth, providing

With refurbishment to the airport’s crosswind and main runway now complete, the ‘north/south’ runway has been permanently closed. This will unlock the future development of CGX Connect – the airport’s flagship new commercial development, located on its northern

The pandemic did delay the project by 3 months, and I have been presented with many challenges along the way. It has been an amazing experience and what an opportunity to be involved in one of the University’s biggest construction projects for more than a decade. “The University has great links with industry, and I managed to secure a placement at Transport for Greater Manchester which helped me decide on the career path I wanted to take and gave me that edge when I was looking for my first graduate job.” Charlotte is now working as the project manager for the new School of Science, Engineering and Environment building (SEE) at the University of Salford and has successfully navigated around the challenges posed by the pandemic delivering a new building that is not only on-budget but has a completion date that is on schedule. Reflecting on her current role, she said: “I have been working on the project for 5 years and it has been amazing and very satisfying to see the construction come to life from inception to completion and occupation. “The pandemic did delay the project by 3 months, and I have been presented with many challenges along the way.

OUR GOAL IS 100% CERTIFIED TIMBER FROM 2025 The Belgian fifthgeneration family company, founded in 1883 Vandecasteele Houtimport still has to deal with old prejudices on the use of hardwood. “Everyone knows that timber is a sustainable material”, says Isabelle Polfliet, Compliance Manager at Vandecasteele, “a lot of users still associate tropical timber with the disappearance of the forests.” Nevertheless, Vandecasteele Houtimport is fully committed to certified timber.

Sustainability and reliability are an essential part of Vandecasteele Houtimport's DNA. The company is determined to achieve the goal of trading only certified timber by 2025. IsabellePolfliet: “As far as softwood is concerned, we are at 99%. The challenge, however, lies with the tropical hardwood and today we are at 66%!” Vandecasteele Houtimport has a clear vision: only certified timber has a future. Substantial investments have been made over the years to be able to realize this future perspective. “You cannot achieve this goal overnight. This is a longterm job, in which all partners must be included. If we want to assure our customers that we keep our promise to only trade timber that comes from well- managed, certified forests, we need to be sure that all our trading partners

share the same strictest certification and sustainability processes as we do.” This has resulted in several actions within the company. “First of all, we were assisted by external experts to get the procedures and protocols in order within our company. For example, we apply a responsible purchasing policy that must be signed by every supplier.” Secondly, the team at Vandecasteele was reinforced with a forest engineer in Brazil. “That way we can keep a finger on the pulse of every shipment and we are able to accurately apply the ever-changing legislation in Brazil with great precision. This sends an important signal to our suppliers. They know that doing business with Vandecasteele Houtimport means: complying with a procedure that is continuously refined and adapted. Every timber transport requires approval. When in doubt the timber is not accepted by us.”

DIGITALIZE Last year another important step was taken in the partnership with 11 Foundry and their product Fibertrace. “This is in line with our intention to digitize all processes within our company. Fibertrace allows us to register all processes related to compliance in a structural and transparent way,” says Isabelle Polfliet. “The choice for certified timber does not mean that we push all non-certified suppliers aside. We have a preference for certified wood. By working together with external auditors, we can carry out field audits and share the results and the expenses with colleague importers. This enables suppliers to gain insight into their processes and where there are areas for improvement. In this way, we will gain certified suppliers in due course.”

vandecasteele.be

Vandecasteele has a long-term commitment to preserving the forests. The family business imports more than 125 different types of wood from 40 countries and has 105,000 cubic meters in stock, mainly certified hard and soft woods. “This wide range of wood species is also due to our support for the LKTS program of FSC Denmark. With this we want to help promote the use of lesser known species. We keep these lesser-known types of wood in stock and offer them as an alternative. Too often, regulations refer to the known types of wood. From the point of view of good forest management, one must dare to choose the right durability class for an application instead of a specific type of wood.”

PRESERVATION OF THE FOREST In a well-managed forest, only mature trees are harvested, which amounts to one to three trees per hectare. After that, felling will not take place for at least 25 years. In this way the forest is preserved for the future. Mother trees, trees with bee nests and the like are of course not harvested.

POSITIVE EVOLUTION Isabelle Polfliet notes that a positive evolution is noticeable in consumer purchasing behaviour. Customers are increasingly asking questions about certification and the origin of the timber. Buyers are becoming increasingly aware of the need to use certified timber. “Importing tropical wood goes further than just asking for certified wood. Internally, the processes and procedures must also be in order. Say what you do and do what you say. This means a continuous evolution within our company, because there are always new insights and legislation does not stand still (‘the new Deforestation Law’). Due to our collaboration with external experts, we are broadening our internal knowledge and continuing to make progress.” Considerable steps have already been taken with the arrival of the EU Timber Regulation, but we

can and should do even better. “We want to see and monitor a stronger application and support for certified timber. Vandecasteele communicates continuously with the users via the website and campaigns in order to get that message out. This is necessary, because the purchase of FSC® certified wood contributes to 14 of the 17 Sustainable Development Goals (or SDG’s) of the United Nations’. Since the year 2000 Vandecasteele Houtimport

has committed itself through the Corporate Durability Charter by signing up to environmental objectives exceeding the applicable legislation. In 2018, the charter started a partnership with CIFAL Flanders, the local HUB of UNITAR, the Training and Education centre of the UN. In 2021, Vandecasteele Houtimport was the first timber company in the world to have obtained the international recognized “SDG Pioneer certificate” from UNITAR CIFAL.

RETROFITTING RESILIENCE What is resilience and how can we ensure our existing infrastructure can be made more resilient for the future with as little disruption as possible. It is without doubt our towns and cities are seeing the impacts of climate change with a greater need to develop greater resilience. It has never been so important that our communities need and want quality of life, wellbeing, and financial security, as well as to be protected from the physical resilience of critical infrastructure irregularities. Cities are at the heart of responding to climate change – action taken at a city scale to build greater resilience to decarbonise has the power to create healthier, more inclusive places at the same time. It is simply not enough to mitigate against the future climate change we also need to adapt to the inevitable impacts as highlighted in our recent #Adapttochange campaign and the current IPCC Climate Change 2022 Report.

The challenge How can existing infrastructure be made more resilient to climate change, with as little disturbance to users as possible, by 2030? Thankfully there is widespread recognition that demolishing existing properties and replacing them with more sustainable alternatives is rarely cost effective nor beneficial to the environment For example, by introducing new heating systems or insulation materials to improve energy performance – is viewed by as a better way to help meet the UK’s net-zero carbon targets.

The solutions Together, we can transform and reuse existing buildings wherever possible, to shape a better future for generations to come. Along with environmental benefits, the commercial and social returns of transforming and reusing existing buildings are also clear.

Greater investment in adaption measures and solutions are needed, nature offers the greatest potential to reduce climate risks. Retrofitting green and blue infrastructure into the existing is all too often overlooked. Deemed impossible or expensive. Retrofitting, however, is possible and has the potential to deliver excellent results across the sustainability agenda. Sauchiehall Street

How we work with you We work with a wide range of clients from the project conception and design stages, through to planning and installation and advise on maintenance thereafter. Whatever the building or infrastructure site, we can successfully enable multipurpose sustainable schemes to include:• Green Walls • Green Roofs • Rain Gardens • Tree Pits • Shared space, including furniture • Off Grid Lighting • EV Charging With over 30 years’ experience, a full suite of innovative products relating to Green, Blue, Smart Space and Air GreenBlue Urban are at the forefront of developing schemes to tackle climate change. During this time, we have worked with incredible clients to deliver 100’s global projects and award-winning schemes, including Greener Grangetown and Sauchiehall Street recognised for their remarkable sustainable credentials. Many schemes have often completely changed the way in which we travel making our daily commute safer and more enjoyable such as Archway Gyratory in Islington to include dedicated bus and cycle lanes softened by the 19 trees installed. Leonard Circus in Hackney is a renowned shared space development, home to street stalls and cyclists encouraging social cohesion that is the sustainable way to meet new needs for the community to enjoy.

CONSTRUCTION TECHNOLOGY HELPS TO PROTECT THE BOTANICS’ ICONIC TREES While hard hats and diggers can be considered at odds with nature conservation, an innovative tree protection system at the Royal Botanic Garden Edinburgh (RBGE), is combining the latest in construction technology with the need to protect a world-renowned living collection of plants.

Arboriculturist Will Hinchliffe at one of the root bridges

The ambitious, multimillion pound Edinburgh Biomes development includes the restoration of RBGE’s heritage Glasshouses but, with construction set to take place in the very heart of the 70-acre site, twelve of the Garden’s 3,500 trees were at risk of damage. Arboriculture specialists at RBGE, environmental consultants Ironside Farrar and construction company Balfour Beatty worked closely with supplier Green Grid Systems to devise a bespoke plan to protect Scotland’s National Botanic Collection. Will Hinchliffe, Arboriculture Supervisor at RBGE explained: “Trees provide enormous value to society, particularly in urban landscapes where they help people to connect with nature.

“However, they are also very vulnerable. A tree which takes decades or even hundreds of years to reach maturity, can suffer irreversible damage in just a few minutes.

As curators of trees which are often endangered in the wild, our priority is to protect and retain mature trees that grow in close proximity to the development site. “In turn, the survival of prominent features will help to embed the site into the natural environment, adding to the sense of an established landscape when the project ends.” Gillian Smith, Technical Director at Ironside Farrar added: “As a world-leading botanic garden, RBGE has specific site conditions which first required careful consideration. Working closely with manufacturer Green Grid Systems,

New path using geotextile cells

the team has adapted the existing systems to suit the Garden’s requirements and have delivered a solution that will secure the best long-term outcome for invaluable specimen trees.” Five years in the planning, the teams incorporated techniques they learned from previous construction projects at the Garden and introduced new technologies. These include an ingenious root bridge of steel piles and beams submerged into the haul road surface. Designed to protect vulnerable root systems, a void beneath the raft-style grid allows space for future root growth without affecting the final paved surface. It will also disperse the weight of heavy construction vehicles, helping to avoid damage to the roots through compaction or contamination of the soil. To minimise the risk of flooding, new paths have been created using porous geotextile cells instead of the traditional covering of tarmac. The honeycomb structure of the cells helps to attenuate surface water, ensuring a more sustainable drainage system. Meanwhile, above the ground, immovable protective barriers have been secured around the rarest of trees. The pioneering action has already attracted visits from tree specialists across the length and breadth of Britain. This not only ensures the safeguarding of trees at RBGE’s worldfamous site, it also brings fresh knowledge and creates a benchmark for best practice across the public and private sectors.

DIGITAL TOOLS: THE KEY TO MAKING BETTER DECISIONS IN CONSTRUCTION Last year, it was reported that the construction industry contributed over £117bn to the UK economy and employed over 2.4 million workers. The industry represents 6% of the total economy and is vital to the UK’s economic success. Given these impressive statistics, we know that construction is a successful sector. But are we fulfilling our true potential? In a competitive industry like construction, making the right decisions at the right time is key, says Sjoerd Springer, Account Manager at Ed Controls. As we all know, the construction industry has been slow to adopt technology; but the pandemic has proved that traditional ways of working are not sustainable for the future and prompted companies to begin digitising their processes. We’re glad to see that the industry is changing to become more efficient and data driven, through use of digital tools like Ed controls.

Access progress anytime, anywhere

Having access to relevant information to make informed, data-driven decisions is key in construction. With digital project management apps like Ed Controls, you can quickly and accurately carry out audits, quality checks, and inspections whether you are present on-site or elsewhere. Thanks to quality management software, your project’s information is permanently available, along with automatically generated inspection reports, allowing for insightful decision making in current and future projects. Data driven insights could include anything from the number of tickets you can complete in any given amount of time, to the average time it takes to complete a job. With this information, site managers can improve projections for future projects by estimating the length, cost, and the amount of labour involved.

How many hours have you wasted on chasing your team for project updates? With a digital project management app, construction workers are able to see the complete overview of a project at every stage, with all the necessary information available in one place, accessible to the right people.

How do you know if your current project is on track? A snagging app can also act as a project management tool for a construction site, as it can hold a wealth of information about the life cycle and status of a project. Not only this but using the insights to “evaluate [your team’s] concerns and suggestions when planning work is highly important” for motivating your team.

When construction workers use digital tools to capture and manage defects on site, they are automatically capturing data. This data can be used to run reports, and progress can

Don’t get left behind – join the digital revolution Digital tools are there to make life simpler and easier. An easy-to-use digital system makes information available to the right people, clearly, quickly, and on any device.

INTERVIEW

Sir Edmond de Lotbiniere (2nd from the left) and Giles’s father, Michael de Lotbiniere (on the right)

INTERVIEW: GILES DE LOTBINIERE Construction UK Magazine sits down with Giles de Lotbiniere, Chairman of Lignacite, to discuss the company’s history and the many benefits of their products. Firstly, congratulations on the 75th Anniversary. What is the secret to the company’s success? Throughout the years, we’ve always tried to make an unusual and high-quality product, rather than being a stack it high, sell it cheap manufacturer. We’ve striven to make our blocks as sustainable as possible, working with designers to give them the products they desire while also offering them something slightly different to the rest of the market.

Something quite fun is the sales technique used by my grandfather. He would take a Lignacite block to a trade show with a wooden handsaw and a hammer and nail. He would then cut the block in two with the handsaw and then knock a nail into one half. This was to show the versatility of the block and how easy it was to build with. Crome Court UEA, Norwich

Talk us through the different types of concrete blocks you produce and what type of block suits different buildings and their structures. Lignacite offers a range of high-quality concrete blocks for above and below ground, including dense, medium dense, and ultra-lightweight. The Lignacite medium dense concrete block is a good all-round performer that is suitable for use in commercial, industrial, and leisure projects. It is robust and durable, providing excellent sound reduction and high levels of fire resistance. Lignacite also has low air permeability, resulting in thermally efficient buildings, as well as a strong background for heavyduty fixing.

In terms of longevity, the most important and impactful innovation related to our success has been the use of wood. Right from Day 1, we’ve been putting this recycled and renewable material into our blocks, using soft cured offcuts from doors, windows, and even scaffolding boards, which would otherwise go to landfill or be burned.

The Lignacrete dense concrete block is suitable for a wide range of applications.

How and why was Lignacite formed in 1947? The company was founded by my grandfather, Sir Edmond de Lotbiniere, who was an engineer in the army. After retiring, he was approached by an inventor who had produced a new mix design for concrete blocks that included wood, sand, cement, and an expensive admixture. My grandfather started making blocks in Brandon using the inventor’s formula, but one day, the admixture ran out. Despite this setback, my grandfather continued making the blocks and they turned out equally well. It transpired that the magic ingredient was the wood, which makes the blocks light, warm, smooth, and good in a fire.

There are very few blocks that provide this flexibility. If you are putting electric cables into a wall, for example, being able to cut or chase into a block is a very valuable feature.

It has excellent levels of sound insulation and high strength capability, making it especially suitable for use in separating and partition walls.

The Shard

How do the blocks contribute to housebuilding, and have you seen an increase in demand over the years? Generally, we’ve seen an increase in demand over the years, but housebuilding tends to be cyclical. When Lignacite started, our blocks were manufactured almost entirely for agricultural and commercial buildings. However, in recent years, we have moved more towards domestic dwellings and see this as an area for further expansion in the future. The recycled content of our blocks has most certainly helped to increase demand in the housebuilding industry. Over the years, we’ve looked at cardboard, paper, hemp, straw, graphene, recycled plastic, expanded glass, and even sugar beet pulp waste, as we’re located in the biggest sugar beet growing area of the country. Moving forward, we’ll continue this exploration and try to incorporate other recycled and sustainable materials into our blocks.

The most recent test conducted in a UKAS approved laboratory focused on the improvement that can be realised by adding acoustic treatment to one side of Lignacite blockwork. It was based on 215mm Lignacite blockwork with an acoustic treatment comprising a 50mm ‘C’ stud frame set back 20mm from the face of the blockwork, with 50mm acoustic quilt and finished with high-density plasterboard. The measured weighted sound reduction was found to be 66dB, Rw – an exceptional level of performance. The Chelsea Barracks development in Belgravia, London is just one example of a project that used Lignacite Paint Grade concrete blocks to achieve good sound insulation performance.

With regards to fire safety, the addition of wood in our blocks gives them a very good fire rating. Conventional concrete made with stone ultimately shatters under intense heat, whereas the wood in our blocks is locked in, denying a supply of oxygen to the flames. This means the blocks calcify and harden in a fire, giving superior performance. Both the Lignacite medium dense block and the Lignacrete dense block in 100mm thickness have a two-hour fire rating, rising to three hours for the 140mm versions. These ratings represent the amount of time a block can withstand fire before it collapses. As a forward-thinking business with a history of innovation, we’re constantly searching for ways to make blocks that are lighter, warmer, greener, and more resistant to various conditions to help housebuilding contractors create the best and highest-performing structures possible.

Why are concrete blocks a popular choice for housebuilding contractors? Concrete blocks are a popular choice for housebuilding contractors because of their versatility and cost-effectiveness. Ever since the widespread manufacturing of blocks began in the early 1900s, they have been a known and trusted building method, which continues to this day.

Chelsea Barracks

With the Lignacite block range providing excellent sound and heat insulation, high levels of fire resistance, and strong sustainability credentials through the use of recycled materials, we see a bright future for the humble concrete block. In certain types of buildings, how can these blocks solve problems around sound insulation and fire safety? Research commissioned by Lignacite has confirmed the potential for block walls to achieve high levels of sound insulation.

Schöck has introduced a dedicated new solution – the Sconnex type W. It is a product that offers outstanding insulation performance, even at 10,000 feet on one of the most iconic mountains in the Alps.

LATEST INNOVATIVE SCHÖCK SOLUTION REACHES NEW HEIGHTS Minimising linear thermal bridges at the wall connection to the floor, or floor slab, has been a long-standing problem with reinforced concrete construction. Around 40% of all thermal bridges in a building are caused by walls and supports, which in turn are responsible for about 10% of heating energy losses However, Schöck has now introduced a dedicated new solution – the Sconnex type W. It is a product that offers outstanding insulation performance, even at 10,000 feet on one of the most iconic mountains in the Alps.

Scaling the Italian-Swiss border at almost 15,000 feet, the Matterhorn is both one of the most recognisable of the Alpine peaks and one of the most challenging. For mountaineers, the favoured access route is along the Hörnli Ridge, a few kilometres to the south-west of Zermatt in Switzerland. Which is why, near the foot of the ridge at just over 10,000 feet, the Hörnlihütte (Hörnli Lodge) was first built there as a base camp in 1880, followed by the Hotel Belvédère in 1909. The two were merged in 1987 and although the buildings have

been subject to a number of changes since their original construction, by far the most ambitious and challenging project is the recent demolition of the Hörnli Lodge, replaced by a completely new state-of-the art structure, incorporating the Belvedere.

The High Alps is a harsh working environment Since the Hörnli Lodge is not connected to public utilities, natural resources like solar energy and the water supply are crucial. The sloping roof is now equipped with solar panels and a natural meltwater pond nearby provides the water source, which is pumped to an underground storage tank before purification.

Editor’s Recommendations spruce wood dominates the interior, helping to provide a sense of warmth and well-being. The buildings with their latest energy-saving and environmental technologies may be a comfortable refuge for climbers and other guests, but it was not that comfortable for those involved in the design and construction of the project. The working environment in the High Alps is a harsh one. The ground is extremely steep, there are very narrow site conditions and keeping to a tight schedule for the outside work was crucial, given the limitations imposed by seasonal Alpine weather conditions. In addition, the only access to site is by means of a narrow, steep path and the construction teams and all materials – including the concrete for the base slab and walls for the basement – had to be flown in using helicopters. Two helicopters commuted constantly between the site and the concrete plant to fly in the required 17 cubic metres of concrete and pour it from the air. Each carrying around a cubic metre of concrete each flight.

Minimising any heat transference was critical As the building was constructed on a poured in-situ concrete slab, a particularly critical area was the importance of minimising any heat transference between the buildings and the slab. With reinforced concrete construction, linear thermal bridges at the wall connection to the floor, or floor slab, have always been a major problem for the building industry. Schöck, the market leaders in the development of structural thermal breaks for balconies and other cantilever constructions, has now innovatively applied its Isokorb expertise to reinforced concrete wall and support. The result is the Sconnex type W, an application-friendly, dedicated solution that contributes to a permanently sustainable building concept.

The Sconnex type W

Harsh working conditions (Photograph – Michel Bonvin)

The product offers enormous energysaving potential and by reducing the heat transfer coefficient helps buildings meet the highest energy standards – without requiring flanking insulation – which is less energy efficient. If under-slab insulation is employed, heat loss is reduced by up to 59%, but if above-slab insulation is used, heat loss is reduced by up to 80%. Serious energy loss in the area of the thermal bridge also means that the temperature of the interior surface is lower and if the area becomes too cold it can lead to condensation. Over time, mould is likely to form, potentially damaging the building structure and even posing a health risk to the inhabitants. The outstanding insulation performance of the Sconnex type W, even in harsh conditions such as the High Alps, is combined with an excellent load-bearing capacity, which transmits very high pressure, tensile and shear forces in the longitudinal and transverse direction. This is made possible by the use of a pressure buffer consisting of ultra-high performance fibre reinforced concrete. A material which achieves compressive strength levels in excess of 175 N/mm2, but with extremely good flexural strength as well.

Steel Feature

JOURNEY OF METALS: STEELMAKING Steel is part of our daily lives – from the kettles we make our morning coffees with to the trains that take us to work or on holiday. We are surrounded by it. This ferrous metal has transformed our world. Yet the bulk of the raw materials used for steel production have traditionally come from mines all over the world, emitting significant quantities of greenhouse gases and causing environmental damage.

One benefit of using EMR’s scrap metal is that we can select recycled materials which already contain these additional metals, reducing the need for virgin mined metals. At EMR, we’re helping this essential industry to adapt, putting recycled steel to use in the kettles and trains of the future. To understand the significant challenges involved, it helps to understand the way steel production works today.

Of the two main methods of steel production, the most common is the basic oxygen steelmaking (BOS) process which uses iron ore from the ground to make steel in two stages. The iron is first extracted from the ore at temperatures of around 2,000˚C in a blast furnace where iron ore reacts with coke, made from coal, in a reaction that produces liquid iron. If the process stops here, it creates pig iron. Like steel, pig iron is a mixture of iron and carbon, but the high level of carbon means the metal can become brittle. Despite this, pig iron is still used in some applications as cast iron, for example engine blocks. However, for some applications it would not be appropriate. If the central reservation barriers on a motorway were made of pig iron they would most likely shatter on impact. To create a metal that is fit for purpose as a structural product, the second, Basic Oxygen Steelmaking (BOS) stage takes the liquid iron and pours it into a BOS converter where excess carbon and other impurities can be removed. This is where EMR comes in. To make the process as effective as possible, the BOS plant uses scrap metal (approximately one-part scrap to four parts liquid iron) which acts as a coolant. Adding recycled scrap metal also reduces the embodied carbon

emissions of the final product, because the process of collecting and preparing recycled metals generates much lower carbon emissions than the processes of extracting and converting iron ore with coal to make pig iron.

The trends that are making steel makers invest in new EAFs have also led to the development of new grades of low carbon impact ‘green’ steel. Green steel has a reduced carbon footprint thanks, primarily, to its use of a high proportion of recycled metal, but also because of the way the iron ore component is converted with lower carbon emissions by using natural gas rather than coke in the Direct Reduced Iron (DRI) process. At the next stage of the steel manufacturing process, known as

secondary steel making, the amounts of other key metals in the material are adjusted, depending on its intended use. For example, if a customer needs easilymachinable free cutting steel, adding lead can make the final steel easily-machinable while adding nickel, molybdenum and other metals can deliver improved corrosion resistance or other mechanical properties. One benefit of using EMR’s scrap metal is that we can select recycled materials which already contain these additional metals, reducing the need for virgin mined metals. The second main process of steel making is the Electric Arc Furnace (EAF). This method dates back to the early 20th century. It is widely used in the USA today and is increasingly being adopted in Europe. EAFs can use up to 100 percent recycled steel, although often they will mix recycled steel with new iron derived from iron ore. The steel industry is increasingly exploring how to use more recycled materials from suppliers like EMR because it helps to keep operational costs low, whilst also reducing their carbon footprint. EAFs have key role to play in this.

metal, but also because of the way the iron ore component is converted with lower carbon emissions by using natural gas rather than coke in the Direct Reduced Iron (DRI) process. Green steel benefits the customers of steel companies by helping them to meet the growing demands for low carbon products from their end users: as society combats climate change. More and more organisations are specifying products with lower embodied carbon emissions, a trend that is only going to continue.

And there are other advantages. Unlike blast furnaces, EAFs can be switched on and off with relative ease, allowing for a more flexible and profitable steel industry. They can also use renewable power. This greatly reduces their associated carbon emissions, especially when compared to blast furnace steel making, which uses coke derived from coal as the main energy source.

There is further the industry can go. Many steel manufacturers are developing ultra low carbon processes for converting iron ore to liquid steel using hydrogen generated from renewable power in the DRI process. The carbon impact is reduced further by mixing the hydrogen based primary iron with recycled steel scrap. This approach will help the industry achieve its ultimate goal of carbon-free steel production in the coming years.

BARRATT DEVELOPMENTS LAUNCHES ZERO CARBON HOME CONCEPT WITH CARBON NEUTRAL SILESTONE® SURFACES SPECIFIED Barratt Developments’ “Zed House” is the first zero carbon house by a major housebuilder to substantially surpass the Future Homes Standard by delivering a carbon reduction of 125%*. Last year Barratt announced that all its new homes will be zero carbon by 2030, and to help achieve this goal, carbon neutral Silestone® by Cosentino’s Cincel Grey surface has been specified throughout the kitchen of this project. Built with over 40 industry partners to showcase the future of sustainable living, the property set on the main campus at the University of Salford will be occupied and monitored to assess its performance over time. It will also be an industry showcase home to demonstrate what is achievable, particularly from a mainstream, volume housebuilder. The Symphony kitchen’s worksurface and splashback are made from Cosentino’s Silestone® in Cincel Grey. Available in 2cm and 3cm thicknesses with a velvety Suede texture, the neutral colourway complements a wide range of kitchen styles and colours, from classic Shaker designs to contemporary high-gloss slab doors. It is part of Cosentino’s Sunlit Days Collection, the first carbon neutral collection in the quartz surfaces and engineered stone market, which also features the pioneering and exclusive HybriQ+® technology. Characterised by the company’s commitment to the environment, the circular economy and sustainable management, the manufacturing process of HybriQ® technology uses 99% reused water from the production processes and 100% renewable electric energy. HybriQ+® also includes a minimum of 20% recycled raw materials in its composition, alongside mineral raw materials. The result is a timeless worksurface with high-spec performance, hygiene certification and a 25-year warranty. Further demonstrating Cosentino’s commitment to sustainable surfaces, the CO2 emissions of the entire life cycle of the Sunlit Days series has been offset by calculating its carbon footprint, reducing

impact and offsetting its emissions by continually participating in voluntary offsetting projects, which are certified and in the framework of the Voluntary Carbon Market. The initiative is also complemented by a partnership programme for the preservation of the seabed. “We want to showcase what can be done to deliver zero carbon living using the latest technologies and working with the best industry partners,” says David Thomas, Chief Executive at Barratt Developments.

Ultimately, the aim is to find solutions to enable the industry to build high quality, zero carbon homes that customers love, at scale. We can then share this knowledge to help the industry deliver the future of sustainable housing. Designed to show just what is achievable for the housebuilding market in terms of sustainability, the Zed House is a great example of how homes could look in the next few decades. Barratt Developments began by challenging its supply chain partners to bring in the most cutting-edge products to help reduce its carbon footprint.

The result combines a Symphony kitchen made from 100% recycled chipboard, Silestone® carbon neutral worktops and splashback, a stainless steel Franke sink made from 80% recycled materials and a 4-in-1 filtered boiling water tap. The house itself is made from a closed panel timber frame with highly insulated cladding and comes with EV charging points, PV solar panels and battery storage. The interior also includes electronic hands-free taps to reduce water consumption and a smart electric tariff that automatically moves energy usage to access the cheapest rates. The Zed house will be lived in and monitored over time to assess its performance. * Measured against 2013 ADL1a but using Future Homes metrics and targets.
