The Costain Skanska joint venture (JV) has excavated new Crossrail tunnels at Paddington Station in London, UK, as part of the construction of the new station.
The JV will excavate the earth between the two tunnels, creating a large open station-platform level.
Upon completion of the excavation, Costain Skanska will lay the track bed, as well as begin constructing the platforms for the new station.
Following the completion of the platform and track bed construction, system-wide contractor ATC, comprising Alstom, TSO and Costain, will fit-out the new tunnels with track and other rail infrastructure.
Costain Skanska JV construction manager Andy Mooney said: "Reaching the tunnels marks an important phase in the construction of Paddington Station.
"The excavation down 16m underneath Eastbourne Terrace will allow us, once we have removed all of the 2,640 individual tunnel segments, to start the construction of the platforms and track bed."
