Costain to carry out Hammersmith Flyover strengthening

Costain has won the £60 million Hammersmith Flyover strengthening project.

The firm has been awarded one of four places on Transport for London’s (TfL) framework for early contractor involvement (ECI) and construction, initially worth approximately £200m overall.

The strengthening of the flyover is its first project within this framework.

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

Hammersmith Flyover, which is used by 90,000 road users a day, is situated on one of London’s main strategic routes, and the strengthening work is essential to keep London moving.

The framework and the ECI work for Hammersmith will 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.

“This award further enhances Costain’s reputation for innovation and engineering expertise across the whole life cycle of an infrastructure asset, as well as our recognised commitment to providing our customers with certainty of delivery and cost within a collaborative working approach.”
