Osborne will be responsible for delivering the Crossrail west outer signalling renewal – civils works, covering a 17-mile section from West Drayton to Maidenhead.

The contract works involve the design and construction of infrastructure in support of the new signalling works, including concrete bases for signalling equipment and buildings, renewal of concrete cable troughs and works such as site clearance, fencing, steps, guardrails and safety barriers.

This section of the western main line provides an essential link for passengers travelling to central London and accessing Heathrow Airport. When it opens in 2018, Crossrail will offer faster, quieter, greener and more reliable services to passengers on these routes.

The work is set to be completed in phases with the final phase finishing in spring 2013.
