Ultra Sites

The construction industry is acutely aware of its need to work more closely together, and is increasingly realising the commercial, social and environmental benefits of greater integration.

Ultra Sites provide the next level of achieving even greater standards and collaboration across the entire industry.

Ultra Sites represent the pinnacle of achievement in exceeding the Scheme’s Code of Considerate Practice by demonstrating and promoting the highest standards of the Scheme and actively seeking to improve not only their own performance but that of the wider construction industry, particularly through the supply chain.

The Ultra Site vision is for sites to become beacons of best practice in the construction industry and a catalyst for exceptional leadership, collaboration and innovation. An Ultra Site will be a leader in inspiring people to join the industry. The aim of the Ultra Site initiative is for the Scheme to deliver appropriate support so that this vision can be achieved. This involves establishing a collaborative working model where subcontractors and suppliers on Ultra Sites are also registered with the Scheme.


A registered site can become an Ultra Site when an agreed number of trade contractors and suppliers working on that site are separately registered with the Scheme. To qualify as an Ultra Site a number of other criteria must also be met, details of which can be found here.

Ultra Site pilot

During 2015-2017, the Scheme piloted Ultra Sites with a consortium of some of the country’s leading contractors and industry clients. They are: Canary Wharf Contractors; Galliford Try; Highways England; Interserve; Kier; Mulalley; R G Carter; RG Group; Robertson; Robert Woodhead; Tarmac and Willmott Partnership Homes. With their assistance, the Ultra Site initiative has been developed and refined so that it achieves the ultimate commitment in demonstrating considerate construction.
