Latest Crossrail stations out to bid
Bond Street: Cost £200m,
60 months, Contract 412
The Bond Street Crossrail station is not actually located on Bond Street, due to the 260m platform length and restrictions caused by Jubilee and Central Line underground tunnels.
One of the technical and construction challenges is the ticket hall locations within Mayfair where many nearby buildings are Grade I and II listed.
Contractors will need to monitor vertical and lateral ground settlement around the station and along the route of the running tunnels.
Station box excavation will take place before the Tunnel Boring Machines pass meaning material will need to be removed by lorry with minimal disruption to Mayfair residents.
Tottenham Court Road: Cost £200m,
46 months, Contract 422
The new station entrances at Centre Point will be a key design feature of a new public piazza in the West End
The new Crossrail station will be integrated with the Tube station to form a combined station that will stretch from Soho to Centre Point.
At nearly 1km in length the combined Tottenham Court Road Tube and Crossrail station will require entrances in Soho and Oxford Street and Centre Point.
The station will be constructed with five levels with the ticket hall at street level
Liverpool Street: Cost £300m,
70 months, Contract 502
A new Crossrail ticket hall will be constructed beneath Liverpool Street close to the Broadgate development.
Nearby, a 40m-deep box structure will be located on Blomfield Street to accommodate ventilation, electrical, mechanical and systems equipment.
At the western end, a further new ticket hall will be built by developing the existing Moorgate station ticket hall. The development in which this is housed also contains a 33m-deep draught relief shaft, which has already been built in its lower basement to aid the Crossrail development.
Whitechapel: Cost £250m,
72 months, Contract 511
Carillion Civil Engineering has just started on preliminary piling and diaphragm wall engineering works at the site.
There will be four new structures built as part of Whitechapel Crossrail station: Crossrail Platforms, Cambridge Heath Shaft, Durward Heath Shaft and the Ticket Hall and Concourse.
The most visible new structure – and the one that is at the centre of the Whitechapel station design – is the new ticket hall and concourse. They will replace the existing single storey concourse and passenger bridge
The 200m long Crossrail platforms are in deep tunnels to the North of the existing station, and fed by a bank of three escalators connecting to the new concourse.
The tunnels will be excavated starting from a temporary shaft at the west end of the Cambridge Heath Shaft worksite.
