| Project Detail |
Skanska, as part of the Skanska Costain STRABAG joint venture is delivering full detailed design and construction of Phase One of the UKs new high-speed railway in the southern section of the overall High Speed Two (HS2) project.
The contract involves the construction of major tunnels in the approach to the London terminus at Euston station of the Phase One route. The route length being delivered by the joint venture covers just over 26km, with two 21km long and up to 50m deep tunnels running from the London terminus at Euston station to West Ruislip.
Six giant tunnel boring machines (TBMs) will be used to excavate the 21km route, while a seventh TBM will excavate a logistics tunnel, to be used to bring construction materials into the tunnels and remove muck. The first two TBMs will go nonstop for 22 months while the whole tunnelling programme is expected to take three years from the start of the first TBM drive to final breakthrough. |
