Crossrail has announced the final tender for Crossrail’s tunnels - for the drive from Plumstead Portal to North Woolwich Portal.
Package C310 is for the twin 6.2m diameter, 2.6km tunnels that begin the Abbey Wood spur to the south east of Crossrail’s route.
Crossrail’s chief executive Rob Holden, said: “This is an important day for the programme. The invitation to express interest in the Thames Tunnel contract means that we are progressing with the procurement of all three running tunnels contracts. It is another significant step towards delivering Crossrail on time and to budget.”
The scope of work includes, but is not limited to:
- Review designs during the pre-construction period to improve buildability and to mitigate risk;
- Construction of the tunnels extending beneath the Thames, sumps for tunnel drainage, cross passages, a shaft at Plumstead, portal structures and launch chambers at Plumstead and North Woolwich including head house structures, ramps, diaphragm wall, escape and intervention stairs, flood protection and associated heritage commitments;
- The design (including provision of inputs necessary for CRL to obtain local planning consents) and construction and eventual removal of a segment manufacturing facility local to the Plumstead Portal worksite;
