The work is being carried out using Transport for London’s early contractor involvement (ECI) and construction framework. Costain is one of four contractors appointed to the framework and will carry out the Hammersmith work as its first contract.

The full project scope will be defined during the ECI phase phase, but is likely to involve strengthening the flyover using post-tensioning, replacing bearings, waterproofing and resurfacing the deck, and replacing the drainage.

The framework and the ECI work for Hammersmith start immediately; the framework will run for four years.
Andrew Wyllie, Chief Executive of Costain, said: “Costain is delighted to gain a place on TfL’s framework, and to commence work on the Hammersmith Flyover which is a technically challenging structure and an important part of London’s infrastructure.”
