This contractor is using a water treatment system which reduces their carbon footprint, provides confidence in their consenting requirements, improves incident response time and reduces usage of chemical consumables. The manufacturer identified that other water treatment systems treated construction waste waters for Total Suspended Solids (TSS) and pH correction regardless of the parameters of the waters going into the systems….

On this project they are displaying subcontractor monthly mileage and monthly carbon emissions. The site has developed and displayed a board on the external hoarding by the site entrance that identifies the sub-contractors on site, their monthly mileage and CO2 produced as well as whether they are registered with the Considerate Constructors Scheme. This demonstrates to the workforce, visitors and…

In collaboration with National Highways and Highway Resource Solutions, this contractor introduced the Intellitag digital system to deliver a carbon-efficient solution while ensuring the safety of their workforce and road users. Using Intellitag helped eliminate the need for maintenance checks of temporary traffic management. The Intellitag digital device is fitted to signs or equipment using a mounting bracket. This immediately…

The site team worked alongside their design team to re-design a previous project in order to build a new primary school as Net Zero in operation. In order to assess the carbon performance of both projects, they were each modelled separately in CarboniCa, which is their in-house digital carbon reduction tool. Initially, the school was modelled retrospectively in 2022 based…

This contractor installed a 120m long temporary bridge providing the travelling public and pedestrians with a safe route while the Southern Piled Viaduct is demolished and replaced. The site team and design team were challenged with creating a sustainable diversion where all materials associated with the diversion were to be either re-used or repurposed. This was achieved while constructing to…

This contractor is tackling operational carbon through the utilisation of an energy monitoring system. This has a series of meters across the project office and site, electric supply and consumption can be monitored on an hourly basis. The biggest focus is on tackling out of hours consumption, with this system they are able to set email alarms which notify of…

This contractor is utilising the gripple bracketry system for all electrical containment on the project. Using this system they have saved an estimated 720 hours on site through efficiency, an estimated 2,408kg material weight and an estimated 5,466kg CO2 embodied carbon. This eliminates hot works for cutting bracketry on site. To find out more, click the link below.

The project team worked collaboratively with the client to discuss ways to generate carbon reductions within the build. Through engaging with their supply chain partner, they decided to review the use of electric arc furnace steel for the steel frame. This uses recycled steel to be reused into the new structure. The steel frame is made up of 98.6% of…

This contractor sourced a supplier that produces co-extruded top-quality window profiles, enabling different PVC materials to be processed on the core of the profile and the outer skin. The use of recycled material means that valuable secondary raw materials can be re-used, which helps to reduce the impact on the environment. The supplier is able to sort, shred, clean and…

This contractor have purchased a battery operated rebar cutter that eliminates the use of a petrol powered saw. By using this item it eliminates any hot works, when using a petrol saw it produces fumes and requires storage of flammables and any vibration associated hazards. There are also significant health and safety benefits for operatives on sites using this tool.

The Wi System is a simple, yet extremely versatile alternative to traditional windposts and lintels. It is a method of providing structural support to masonry panels subject to lateral load and can allow the uninterrupted construction of ‘oversize’ blockwork walls with unrestrained lengths of 11m and heights of 8m. Hollow column and trough blocks allow the construction of integral reinforced…

This contractor has taken part in a circular plasterboard case study in partnership with Loughborough University, ENVA and British Gypsum. The initiative is all part of an EU Horizon 2020 project, ICEBERG, which aims to improve the economic viability and market potential of end-of-life building materials. This provides designers, manufacturers, builders, and recyclers with advanced smart and technological civil engineering…

The original design required a series of concrete retaining dams to control water flow and overflow through the sustainable drainage systems (SuDS). Originally the design was to cast these in concrete on site. The first improvement was to use pre-cast lintels with a stone topping installed on site. The final iteration was to move to a fully precast unit off-site including…

Cemfree Greenbloc is a high-density load-bearing concrete block, that delivers a bulk dry material density of 1850-2000 kg/m3. Made from class 1 aggregates and incorporating the Cemfree Binder, the blocks comply with H.S.E regulations and are manufactured to BS EN 77. By not using cement the product can achieve a CO2 reduction of up to 73% as well as a…

The remote location of the noise and dust monitors on this project required a power source to be installed. Solar alone would not be sufficient to power them and a diesel generator used finite fossil fuels, therefore they combined a hydrogen cell with solar panels to provide enough power to run the monitors 24/7. The hydrogen used can be created…
