Gen Zero is a research project that the DfE & the contractor have led and is based on a construction approach that will form a “Kit of Parts” (platform) to build ultra low carbon sustainable schools, using a fixed grid, timber construction which are adaptable to user needs and demountable to ensure longevity of use. The practical classroom pod will…

A large number of skips can and have been filled in the past and seemingly potentially useful insulation is taken away by waste removal contractors and simply thrown away, usually into landfill. This contractor asked Shredall to specify and advise upon the size of an appropriate compactor to fit into their site and training was carried out for the general…

This contractor changed the design to use Eco Sheet Piles Plus throughout the project which significantly reduced carbon. These are part of the XCarb brand and are a recycled and renewably produced initiative, based on the Electric Arc Furnace (EAF) route using 100% recycled material in addition to using 100% renewable electricity sourced from the same power grid. This allows…

This contractor is using warm lay tarmac for the site compound car park, this significantly reduced the carbon for this activity by up to 15% per tonne. This has numerous benefits including: No requirement for any specialist equipment to lay and no compromise on performance Improved site safety as the risks of burns are lessened Improved air quality and visibility…

Working on an existing embankment with restricted working room behind residential properties, meant the installation of a traditional piling mat was not feasible without significant land take of the rear gardens of the residential properties. Traditionally for these piling works the contractor would install a pile mate and use a 14t tracked excavator with an EMV attachment. Therefore, the contractor…

PaperStone is a UK based material made of post-consumer recycled paper laminated with a petrofree resin. The material is rainforest alliance certified and has low embodied carbon value of just 28 kgCO2e per m2 compared to the 94 kgCO2e per m2 of Corian – the typical alternative to work surfaces. This represents a 70% reduction in embodied carbon and is…

On this project they faced a question as to whether they would repair or replace the damaged cast iron façade, with over 3000 components this was no small task. They sourced a specialist supplier who conducted a comparison life cycle assessment of the remanufacture of cast iron and compared with the manufacture of new cast iron components, this concluded that…

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…
