A new electric road marker vehicle has bee used on the project, this new technology hasn’t been used on a site in the UK before. The vehicle reduces carbon emissions, as it takes less energy to heat material for operations as the material is sprayed at 75 degrees instead of 180 degrees for joint sealing. This Zero Emission Sprayer will…

The contractor has developed and financed a construction-specific climate emergency training course in conjunction with three other contractors in Northern Ireland, Business in the Community and Keep Scotland/Northern Ireland Beautiful. This course helped attendees to make the link between their own lives and climate change, in addition to acquiring the knowledge to lower their carbon footprint, with typical realised carbon…

This contractor has rolled out an environmental initiative on site, to allow all personnel to calculate their individual carbon footprint. A poster is available within the site compound, displaying a QR code that links users to the WWF Footprint Calculator. Those who scan the code can then complete a short questionnaire, answering relevant questions on their diet, travel and home…

The contractor is using the lowest embodied carbon structural steel product available and is the first project in UK to use this. The steel comes with a cost uplift over other rolled steel sections. Wider uptake of this will help to significantly reduce the embodied carbon impacts of the built environment. To find out more, click the link below.

This contractor has used 3D concrete printing to produce the capping beams for a sheet pile flood wall. The beams have a lower embodied carbon than traditional cast in-situ or precast concrete beams and therefore this has helped to reduce the site’s carbon footprint. Each beam is also bespoke, using 3D printing allows each beam to be made to the…

Electric Multi Service Vehicles (MSV’s) are being used as opposed to diesel or track-bound vehicles on this project. These vehicles will be used to transport segments for the TBM as well as people along the tunnels within the project. Electric (MSV’s) will help the contractor reach their ‘Diesel free by 2023’ status and they are aiming to become the leader…

During the initial phase of works, a direct mains feed was not available for the welfare and site supplies, therefore a generator was required. To address planning constraints, nuisance to our neighbours and carbon footprint/emissions associated with large diesel generators, they considered the use battery supply units to operate primarily out of hours, but also to address inefficient running out…

This contractor created an ‘Educating Our Supply Chain’ video on carbon reduction to support their business commitment towards Net Zero, which was publicised and shared with their key supply chain partners. A tailored launch session for their Net Zero Partners scheme was arranged and delivered to key subcontractors and suppliers to help prepare and align them with their commitments through…

This contractor has established a ‘Carbon Focus Group’ to develop an inclusive approach to generating discussions at all levels in the company. The new focus group has already developed a carbon specific toolbox talk that has been rolled out on site to educate and inspire the workforce to think about ways of reducing carbon. A number of initiatives were discussed…

This contractor coordinated with their road surfacing contractor, and construction material producer, to lay a 1755m2 area with a rubber modified asphalt. The product is an environmentally sustainable alternative to conventional asphalt. The mix uses end of life tyres which are converted into new roads and pavements, resulting in up to 5% lower CO2 emissions during production. The product is…

Reinforcement bars are used as a tension device to reinforce and strengthen concrete in building structures. Basalt FRP (fibre reinforced polymer) was used in guidewalls instead of standard steel reinforcement bars. Basalt is a naturally occurring volcanic rock that provides similar strengths to steel reinforcement in the right applications. Basalt FRP is 5 times lighter than steel whilst providing similar…

Spotlight on… posters have been designed for general display in and around site welfare facilities. The Scheme has developed a collection of A3 posters from the series of ‘Spotlight on…’ learning toolkits. This resource has proven valuable for display on site and raising awareness amongst the workforce and visitors. To purchase these products, click here. To download a free electronic…

As part of this contractors commitment to utilise zero carbon technologies, A wind turbine has been positioned on the project. The wind turbine is used to charge a battery which then distributes energy powering some of the sites temporary electrics. The plan moving forward on the project is to increase the number of wind turbines onsite to maximise this low…

The embodied carbon for this prohect’s offices was calculated using BS EN 15978:2011 and guidance from RICS ‘Whole life carbon assessment for the built environment’. For the RIBA Stage 4 design, the embodied carbon to practical completion is predicted to be 904 kgCO2e/m2, showing performance to be well within the Greater London Authority benchmark of between 900-1000 kgCO2e/m2 expected for…

As part of this sites drive to reduce carbon in line with their 2030 and 2040 commitments, the site participated in avcarbon reduction group video, discussing previous innovations including Thermal Lightweight Aggregate. This video was originally been made available for internal use but has now been delivered and cascaded to their subcontractors working on the project and the wider contractor’s supply…
