Construction of Crossrail, the East-West railway for London and the South East took a big step forward today when Crossrail published inviting bids for tunnelling packages for two of its central London stations, Bond Street and Tottenham Court Road.
The packages worth in the region of £100 million include construction of platforms, concourses, cross passage and escalator tunnels using sprayed concrete lining techniques, and the construction of temporary construction access shafts.
The contracts include:
- Review of Crossrail's designs to improve buildability and to mitigate risks;
- Transportation of all excavated material from the works to pre-designated transfer facilities adjacent to the River Thames.
- Construction of platform tunnels to be completed ahead of the arrival of the running tunnel Tunnel Boring Machines (TBMs) driving from Royal Oak Portal to Farringdon.
Tender submissions are due by 12:00 p.m. on 5 November 2009 and work on the station tunnels is expected to start in early 2010.
Construction of the Eastern and Western Ticket Halls and the architectural and services fit-out to these ticket halls and to the station as a whole will be subject to separate tenders.
