Laing O’Rourke was selected for contract C502 ahead ofBalfour Beatty/Morgan Sindall/Vinci JV, Costain/Skanska JV and Dragados/Sisk JV.
This is the fourth of eight station contracts to be awarded.
Crossrail programme director Andy Mitchell said: “As with the Paddington, Farringdon and Whitechapel contracts, high quality bids were received for Liverpool Street station. The main construction contract for Tottenham Court Road station will be the next to be awarded in mid-2012.”
Crossrail’s Liverpool Street station will serve the City of London and provide interchanges with London Underground’s (LU) Northern, Central, Metropolitan, Circle and Hammersmith & City Lines, connections to Stansted airport and National Rail services at Liverpool Street and Moorgate stations.
The new Crossrail station will be located below existing Liverpool Street and Moorgate stations and Finsbury Circus.
At the eastern end of the Liverpool Street Crossrail station, a new Crossrail ticket hall will be constructed beneath Liverpool Street close to the Broadgate development. At the western end, a new ticket hall will be built by expanding the existing Moorgate station ticket hall. 
The site of the Broadgate ticket hall sits directly above a 16th Century burial ground belonging to the Bethlehem Royal Hospital (Bedlam). Investigations by Crossrail archaeologists have confirmed the presence of up to 4,000 complete human skeletons two to four metres below street level. Excavation of these human remains will be completed before construction of the new Broadgate ticket hall starts. The remains will then be reburied.
Other Crossrail station contracts already awarded are:
- C405 Paddington station - Costain Skanska JV.
- C435 Farringdon station - BAM Nuttall, Ferrovial Agroman (UK) & Kier Construction JV.
- C512 Whitechapel station - Balfour Beatty Civil Engineering, Morgan Sindall & Vinci Construction UK JV.
