Crossrail's underground route beneath London

The shortlisted bidders will tender for the total 18km of the route that comprise the two tunnelling contracts:
Package C300: The Western Running Tunnels for 6.2km of twin 6.2m diameter bored tunnels from a portal at Royal Oak (west of Paddington Station) through to the new Crossrail Farringdon Station, and including a crossover at Fisher Street.
Package C305: The Eastern Running Tunnels for twin 6.2m diameter bored tunnels in three drives - 8.3km from a portal at Limmo Peninsular through to the new Crossrail Farringdon station; 2.7km from a launch chamber at Stepney Green through to Pudding Mill Lane Portal; and 900m from a portal at Limmo Peninsula through to Victoria Dock Portal.
Contracts are expected to be awarded by mid-2010. Invitation to tender the Thames River Tunnel to Woolwich was planned to be tendered at the same time as the central two tunnelling contracts but has been deferred to suit project cash flow and capital draw down better.
Andy Mitchell, Programme Director, Crossrail said: "Crossrail has now started the formal tendering process for the total 21km of new twin-bore rail tunnels that are required by Crossrail. The initail two contracts will form the centrepiece of the project underneath central London and will link the Great Eastern and Great Western National Rail lines. Such is the scale of this undertaking that Crossrail will next year open a dedicated Tunnelling Academy which will provide Londoners with the necessary skills to work in a variety of tunnelling roles and is expected to train up to 3,000 people by 2015."
Upon award, the successful contractors will commence procurement of tunnel boring machines in accordance with Crossrail specifications; designing and constructing of tunnel segment manufacturing facilities to ensure sufficient supply of tunnel segments are available upon commencement of tunnelling; conducting constructability reviews of the detailed design with Crossrail framework design consultants; and initiating other construction planning, temporary works design and permitting activities in support of site mobilisation.
Tunnelling is scheduled to commence in late 2011 and in accordance with Crossrail programme milestones.
