    Brief

    National Highways seeks partners to design and construct a scaled physical model of the M25 Junction 10 Wisley Interchange integral bridge. This laboratory-based model will complement the existing full-scale monitoring programme, which currently uses 116 sensors to track real-time performance data on the newly constructed bridge. The physical model will enable controlled investigation of structural-soil interaction (SSI) behaviour, allowing researchers to study settlement, stress, and strain under laboratory conditions where variables can be precisely controlled. By combining physical laboratory testing with advanced modelling and live field data, this research will provide evidence to inform updates to PD 6694-1 standards and demonstrate potential benefits including reduced material use, lower construction costs, and improved confidence in integral bridge design and delivery. This is a preliminary market engagement notice under the Procurement Act 2023; participation does not guarantee future contract awards or procurement commitments.
