Contractor wins £115m deal to build new hall for station's underground link.

Contractor Balfour Beatty is to build a new ticket hall for the underground link at King's Cross station after winning a £115m deal for the work.

The firm's civil engineering arm will build the new northern ticket hall at the station, which will allow it to handle up to 92,000 passengers during the morning peak when it is completed in 2011.

The aim is for the work to be finished in time for the Olympics in 2012, with partial completion in 2008 planned to allow access for Network Rail to proceed with redevelopment of the mainline station.

Ian Tyler, Balfour Beatty chief executive, said: "The scope of the work is predominantly below ground and comprises the construction of the Northern Ticket Hall adjacent to King's Cross main railway station.

"It includes construction and fitout of a three-storey concrete box which will provide improved access to the Northern, Piccadilly and Victoria lines via banks of new escalators and Mobility Impaired Person (MIP) lifts. Fitout works include both architectural finishes and the installation of a full range of building services."
