The Brownfield Ground Risk Calculator has been used by the Greater Manchester Combined Authority to calculate risk, and therefore associated risk mitigation costs, for eleven sites along the new Wigan and Bolton Housing Growth Corridor intended to deliver 13000 much needed new homes. Outputs from the brownfield ground risk calculator form the basis of a bid to Homes England's Housing Infrastructure Fund bid for approximately £132 million to support this vital new development. These funds are required to deliver physical infrastructure and overcome ground-related abnormal (unanticipated) costs in the proposed development area.

These plans are regionally significant and will provide some six per cent of the anticipated housing need across Greater Manchester by the year 2037. In addition, nearly 50 hectares of land will also be delivered for employment creating 183 093 square metres of new employment floor space.

The calculator provided risk scores and abnormal cost estimates for all eleven sites, forming important evidence in this funding application. Preliminary knowledge about ground conditions is an important component of any regeneration and development project. Reducing such uncertainties help build confidence and minimises possible failures later in the project.
