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…

On this project the site boundary is the building boundary. To complicate building construction further two elevations, south and west, abut immediately to existing buildings. At a very early stage of the tender the contractor decided to change the designed 10 storey in-situ RC frame to a hybrid concrete frame. By changing all the vertical in-situ RC structural support elements…

This project is a 6-story commercial development Swindon that consists of new office space and surrounding public realm works. As part of the site and office setup, the project team analysed the cost and carbon emissions of traditional items or services and their green alternatives. 12 ‘green’ proposals were evaluated which ranged from procuring renewable sourced energy to retrofitting site…

The contractor developed a methodology to stabilise 6500m3 of wet dredged material (from the sea-bed) on site by utilising a modification of the existing ALLU system, using a site batched cementitious grout to mix with the dredged material to form a homogeneous mix that later cured into a weak concrete. The methodology ensured that this material could stay on site…

This project used heat induction as an alternative to traditional grit blasting to remove existing intumescent paint from the structural steel frame. This method uses heat induction technology, similar to a heat induction hob, to break the chemical bonds between the intumescent paint and the steelwork, allowing it to be manually scraped off with minimal effort. The benefits of this…

Intelligent online tools can allow users to see what CO2, energy, and cost savings can be made by selecting environmentally friendly products. As many industries are now aware, the UK has signed into law, via the climate change act, that the country will be net-zero by 2050. This means that calculating your carbon footprint is a necessary step to understanding…
