Costain commissioned to deliver pre-construction services on A40 Westway critical structures

Costain digital technology solutions


14 October 2020

Costain, the smart infrastructure solutions company, has secured a contract to deliver pre-construction services for the critical flyover structures that carry the elevated A40 from Wood Lane flyover to the west side of Marylebone on the 2.5 mile A40 Westway, for its long-term client Transport for London (TfL).

The contract incorporates concept design for the safety critical elements of the structure.

The announcement follows Costain’s first appointment to TfL’s Professional Services Framework to compete for contracts to provide lean consultancy, quantity surveying, construction project management as well as assurance and quality management, further building on a 20-year relationship with the organisation.

The A40 Westway is one of the busiest roads in the U.K. and a key strategic route, used by 96,000 vehicles a day. Major refurbishment work is needed to keep the A40 Westway and surrounding road network running safely and reliably in the future. Costain previously undertook a feasibility study for the refurbishment of the structures in 2017 and is pleased to be involved in this phase of the project. This project runs alongside a commission to help TfL explore options for the refurbishment of Hammersmith Bridge which Costain secured earlier in the year.

Contract delivery on the A40 Westway will be in two stages, with work on Stage One to validate the design concept, detailed design and programming and cost analysis beginning immediately. Stage Two is a design and build package incorporating the final detailed stage of design and will not commence until further instruction by TfL.

The contract will be digital by default and be managed by a smart delivery platform in line with Costain’s drive to accelerate the digitisation of infrastructure design, delivery and operations to enhance the sector’s productivity and resilience.

Sue Kershaw, managing director of transportation at Costain said: “In this difficult period we’re glad to support our long-term client TfL on this project, which will help keep traffic moving on one of the busiest roads in the country. It’s a clear demonstration that TfL see us as the safe pair of hands to deliver this safety-critical scheme.”
