Crossrail provides a world-class railway connection between the east and west of London.
The project’s goal is to conveniently connect London’s Docklands in the East via West End to Heathrow Airport. It inter-connects with major existing railway lines to the east, west, and south-east of the city. The central section is located below the busy city of London. A total of seven new underground stations are located along the tunnelled section, five of which were constructed using SCL/NATM technologies.
Gall Zeidler Consultants provided design services for the detailed design, specifications, contract documents and construction strategy of the project’s five SCL/NATM underground stations (Liverpool Street, Whitechapel, Bond Street, Tottenham Court Road and Farringdon). The design services also included SCL/NATM ancillary subsurface structures, including ventilation and access / egress shafts, turn-out caverns and adits.
Gall Zeidler Consultants provided senior SCL/NATM technical representatives on site during the construction and the handover period.
All tunnelling works have been completed and the line is in operation since 2022.
