Crossrail, London, United Kingdom
Lots C300, C410 & C435

This project was realized by IGT.

With a length of around 120 km, Crossrail will link the eastern and western extents of Greater London. The heart of the new railway project is the tunnelled section. Twin-bore tunnels with a length of 21 km cross the centre of London.

Between the portals at Royal Oak, Pudding Mill Lane and Plumstead, new underground stations and connections to the existing London Underground were constructed at Bond Street, Tottenham Court Road, Farringdon, Liverpool Street and Whitechapel.

The running tunnels were constructed by earth-pressure-balance machines (EPB-TBM). The platform tunnels, access passageways, cross passages, etc. are mined tunnels with steel fibre reinforced linings.

As part of this extensive and complex project, IGT provided the following services:

• Design checks (category 3 checks) for the temporary and permanent works for the station tunnels, including check analysis and design of the temporary support measures for tunnel excavation works.
• Technical site supervision, including preparation of excavation and support requirements and interpretation of underground monitoring data for the contractor Team BFK at Bond Street, Tottenham Court Road and the Fisher Street Crossover.
