Costain Skanska JV excavates Crossrail tunnels at Paddington Station


Paddington Station

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.

"Reaching the tunnels marks an important phase in the construction of Paddington Station."

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."

The 250m-long and 30m-wide Crossrail Paddington Station is being constructed adjacent to the existing Paddington Station under Eastbourne Terrace.

Paddington is one of ten new stations along the Crossrail route.

Earlier this month, Crossrail's new tunnel from Limmo Peninsula to Victoria Dock was completed, bringing the total number of finished rail tunnels under the programme to 83%.

Work on the remaining twin tunnel from Limmo to Victoria Dock will start in the upcoming weeks with TBM tunnelling is due to complete in early 2015.
