To protect the 80,000 trees that have already been planted and allow them to establish, this contractor installed 6196m of fencing using a Cobalt Plant excavator which runs off Syntec fuel. This type of fuel is a suitable alternative to diesel and HVO, therefore aligning to the projects strategy to deliver using diesel-free construction. The team are also using an…

This contractor has partnered with energy storage specialist Zenobe to help provide clean power for construction sites by utilising second-life batteries (refurbished electric bus batteries) and transforming them into portable batteries. They will be supplied with 20 portable batteries to be used as temporary power sources that run as a cleaner alternative to diesel generators. One battery unit can store…

As part of their commitment to sustainability and carbon reduction, this contractor on their London Museum project has become one of the first to implement Holcim’s ECOCycle Recycled Concrete Aggregate concrete mix. The new mix replaces 20% of virgin aggregate with high quality recycled concrete sourced from construction and demolition waste. By adopting and approving this material, they have reduced…

On this project they have implemented post-tensioned concrete construction to extend existing reinforced concrete slabs. Post-tensioned concrete is one of the most efficient and sustainable types of concrete construction, using 15% less concrete and up to 40% less steel than an equivalent traditional reinforced concrete flat slab. Prioritising low-carbon strategies, the original 1980’s reinforced concrete frame and existing facade are…

This contractor has implemented the ‘hiper pile’ which reduces embodied carbon by reducing the amount of concrete required to maintain the load bearing capacity of the pile. This permits shorter pile foundations which reduces the amount of spoil on site. Being reduced in depth also reduces the risk of augering into water bearing strata. Material volume is reduced by an…

While the industry standard is 4.0mm scaffold tubes, this contractor and their scaffolding contractor are using 3.2mm tubes. This allows for better sustainability performance, lighter handling, and cost savings, all while still meeting BS EN 39 and BS EN 12811 standards. This is a change from the standard scaffolding tube thickness used across the industry. Thinner tubes use less steel,…

This contractor has used a dredger powered by liquefied natural gas (LNG). Making this choice provides a cleaner, more sustainable alternative to traditional marine gas oil (MGO), with emissions significantly reduced. There was a saving of up to 20% for CO2, up to 85% for NO2, and virtually eliminating SO2 and particulate matter. This supported compliance with strict environmental regulations…

Traditional tyres are vulnerable to punctures which then leads to frequent replacements. Therefore this contractor made the decision to use telehandlers with gel tyres which drastically reduce this risk and prevent unnecessary disposal of damaged tyres. Fewer replacements mean fewer manufacturing and transport emissions associated with tyre production and delivery. This results in a measurable reduction in carbon footprint.

This contractor has used modular temporary bracing systems that are fully reusable and adaptable for most structures, significantly reducing the tonnage of steel work required. This modularisation system enhances sustainability, safety, and efficiency. The standard design saves bespoke details and fabrication requirements, allowing standard attachments to suit various projects with different frame sizes, geometry and connection types. It also removes…

This contractor designed, manufactured and install a prefabricated unitised facade to encapsulate the envelope. The prefabricated precast concrete facade panels were produced off site, then they coordinated the design with another subcontractor who installed curtain walling and glazing off site. The panels arrived on site completed and ready for install, before being lifted into position. This method reduced waste onsite…

This contractor is using an electrically controlled, compound heater (Epot) which has been designed for the melting and heating of modern bituminised rubber compounds (hot-melt) used in structural roofing and waterproofing installations. With fast heat up and melting times, and controllable, user-friendly features the Epot avoids the safety and quality control issues arising from the use of gas fired pots….

Collaborating with one of their suppliers, this contractor has developed a solution to the packaging waste being produced on construction projects. Ecopak is a modular system comprising inner and outer polypropylene packaging that can be reused multiple times, allowing for the packaging of mixed types of lighting product and comes with GPS tagging so products can be tracked digitally following…

Fuel consumption savings of up to 7.59% have been verified in a three-month series of trials with trucks owned by the demolition contractor using the product SulNOx Eco Diesel Conditioner. Following these results, this has now rolled out to 100% of the fleet. Based on 2024 fuel consumption data from the Jigsaw Fuel Management System and UK Government conversion factors,…

This contractor collaborated with their supply chain with the aim of reducing their carbon footprint. They engaged with Lowie Bricks UK, who have developed a hybrid brick that significantly reduces carbon emissions compared to traditional clay-fired bricks. Unlike traditional bricks, which are kiln-fired at temperatures exceeding 1200°C and produce 33.36 kgCO², Lowie Hybrid bricks are manufactured using a vibropress process,…

On this project, the contractor installed 136 Solar Panels to the cabin roof at Woolwich by Acute Hoarding for powering the site accommodation. They have used the Enphase App to digitally track energy production and consumption live data. In one month 48% of the site welfare was powered by PV Panels, creating 17,200kWh of energy. This data is published monthly…
