Contractor Laing O’Rourke Construction has won the £300M contract for Crossrail’s C502 Liverpool Street Station contract, it has just been announced.
The firm beat off competition from three joint ventures — Balfour Beatty Civil Engineering/Morgan Sindall Group/Vinci Construction Grands Projets; Costain/Skanska Construction and Dragados/John Sisk & Son (Holdings).
The award has taken place a little earlier than the second quarter as was suggested last month by a report to the London Assembly Transport Committee, which also stated that the award for the contract at Bond Street station had slipped from this year to the first quarter of 2013.
Crossrail programme director Andy Mitchell said that the next station contract, the £200M Tottenham Court Road contract, would be awarded mid-2012.
The construction works
The new Crossrail station will be located below existing Liverpool Street and Moorgate stations and Finsbury Circus. Crossrail will build two new ticket halls, Broadgate in the east and Moorgate in the west, for passengers to access Crossrail trains at Liverpool Street station.
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. Investigations by Crossrail archaeologists have confirmed the presence of up to 4,000 complete human skeletons 2m to 4m below street level.
Excavation of the human remains will be completed before construction of the new Broadgate Ticket Hall commences. This will enable archaeologists to record and preserve London heritage and history. Crossrail will rebury the remains after consulting with the Ministry of Justice.
