Construction will get underway during the later half of 2012.
Crossrail assessed tenders from six bidders for the contract:
- Barhale Construction
- BAM Nuttall Kier JV
- Costain Skanska JV
- Dragados Sisk JV
- Ferrovial Agroman
- Morgan Sindall
Contract C360 will house ventilation and emergency exit facilities between Stratford and Liverpool Street stations. Both shafts will extend around 30 metres below ground.
At Mile End, the works will include the relocation of a coach park and all-weather football pitch within the grounds of the park.
Both will be rebuilt and operational before work starts on the Crossrail shaft to ensure continued access by the local community throughout.
Andy Mitchell, Crossrail programme director, said: “To enable future rail services to operate through the new rail tunnels, ventilation and access shafts are required to be constructed at various locations along the route including Eleanor Street and Mile End Park in east London.
“We are working closely with the London Borough of Tower Hamlets and Greenwich Leisure to ensure that Mile End Park’s sports facilities remain fully accessible throughout the works.”
The ventilation shafts along the Crossrail route have been designed to ensure optimal air movement within the tunnels. As Crossrail trains will be air-conditioned, they will release warm air into the tunnels. The shafts will help extract this warm air out of the tunnels.
