Crossrail announces running tunnels shortlist

Crossrail has announced the shortlist of bidders for two principal tunneling contracts − Package C300 for Western Running Tunnels and Package C305 for Eastern Running Tunnels.

The shortlist is:

  • a joint venture comprising Balfour Beatty Civil Engineering Limited, Morgan Est plc, Vinci Construction Grand Projects and Beton-und Monierbau Gesellschaft;

“This is yet another significant milestone for Crossrail following the start of construction at Canary Wharf earlier this year,” said Crossrail programme director Andy Mitchell.

“In just under two years from now the first of the tunnel boring machines will start out on its journey from Royal Oak towards Farringdon.”

Package C300 for Western Running Tunnels comprises the construction of twin 6.2m diameter bored tunnels from a portal at Royal Oak (west of Paddington Station) through to the new Crossrail Farringdon Station, length of drive approximately 6.2km including a crossover at Fisher Street.

Package C305 for Eastern Running Tunnels comprises the construction of twin 6.2m diameter bored tunnels from:

  • a portal at Limmo Peninsular through to the new Crossrail Farringdon station, length of drive approximately 8.3km;
  • a launch chamber at Stepney Green through to Pudding Mill Lane Portal, length of drive approximately 2.7km; and
  • a portal at Limmo Peninsula through to Victoria Dock Portal, length of drive approximately 0.9km

A total of 21km of twin-bore tunnel are required to be constructed for Crossrail. The shortlisted bidders will be tendering for a total of 18km of twin-bore tunnel.

The contracts are expected to be awarded by mid-2010. Tunnelling is scheduled to commence in late 2011 in support of the Crossrail programme milestones.
