A landmark building tender worth hundreds of thousands of pounds has been won by builders for topping the table on green issues rather than competitive price.
Thomas Vale Construction will build 15 homes in Dudley, West Midlands for the £676,000 scheme by Axis Design Collective. The client, Black Country Housing Association, believes it to be the first time a public-sector housing contract has been let this way.
Three contractors were given an outline design and a fixed budget. They had to submit bids showing the energy efficiency of their building materials. They also had to say what percentage of materials came from renewable sources, such as softwood timber, or were recycled and reusable materials.
The association fed dimensions and component details into a computer facilitator to find out how the buildings would perform.
