Crossrail awards last major construction contract to Costain/Alstom

Crossrail has awarded a joint venture of Costain, TSO and Alstom Transport a £300M contract to fit out the 42km of new rail tunnels being built for the project, it announced today.

Referred to as the last major construction contract by the project, the C610 contract involves installing over new track, power, drainage and ventilation system in time for trains to begin operating from 2018.

Construction of Crossrail’s tunnels got underway in May 2012 when the first tunnel boring machine was launched from Royal Oak. By late 2014, the construction of over 21km of twin-bore tunnel, stretching across the capital via central London and Docklands, will have been completed. To-date over 7km of new tunnel has been constructed under London.

The new tunnels will also require 48 ventilation fans, 40km of walkways, 66 drainage pumps, 40km of fire mains as well as lighting throughout the entire length.

The fit-out works will be carried out within the entire tunnelled section of the Crossrail route between Royal Oak, Pudding Mill Lane and Plumstead Portals.
