Engineering solutions provider Costain has been awarded a £400m contract for the redevelopment of London Bridge Station, Network Rail has announced.
Costain will construct a new concourse at street level, with entrances on Tooley Street and St Thomas Street which would increase passenger capacity from 50m to 75m.
The work is part of the larger Thameslink development linking North and South London through more frequent services and longer trains.
Speaking about the contract, Andrew Wyllie, chief executive of Costain said that the station would remain fully operational at all times to minimise disruption to passengers.

“We are looking forward to commencing work on this very important project, which reinforces our position as one of the UK’s leading engineering solutions providers. Our focus is to design and deliver a world class London Bridge Station which enhances the capital’s infrastructure and improves the journeys of the hundreds of thousands of passengers who pass through the station every day,” said Wyllie.
Network Rail has also awarded a £50m track remodelling contract to Balfour Beatty and a signalling renewal contract to Invensys.
Simon Kirby, managing director of investment projects, Network Rail, said, “The way London Bridge evolved since the mid-1800s left us with a station and a track layout which makes it increasingly difficult to provide the capacity and reliability passengers expect today.
“The Thameslink programme allows the tracks, platforms and station layout at London Bridge to be completely re-designed, boosting the number of trains that can run, unblocking the bottleneck and providing a modern and dynamic station which will make a real improvement for passengers,” he added.
Work is due to commence in full in 2013 and is scheduled for completion in 2018.
