Another
significant mile
stone in the
project
One of the key stations on the CrossRail
project is that at Tottenham Court Road
where a building first was demolished prior
to excavation beginning to build the completely new station.
The top video shows the progressive demolition of the structure that was on site which was done in a very
controlled manner using compact mobile equipment to minimise dust, noise and inconvenience to the adjacent
buildings.
Excavation at Crossrail’s Tottenham Court Road western ticket hall in Soho has now reached track level,
equivalent to seven storeys below ground.
Crossrail’s contractor, BFK, has removed 35,000 m³ of soil from the site at Dean Street over a six month period –
enough to fill all three Olympic swimming pools in the London Aquatics Centre three times over.
This short time lapse video (bottom right) shows the temporary “propping” of the station box walls as excavation
continues to a depth of 30 metres.
Excavation has taken place 24 hours a day, 7 days a week with the team employing a number of excavation
techniques including normal excavators,
long arm excavators, gantry crane and
hydraulic grab to suit the ever increasing
depth.
Work has now begun creating the 1.8
metre thick base slab for the ticket hall.
Sprayed Concrete Lining (SCL) works will
soon begin to prepare the station box to
receive the tunnel boring machines, on
their journey from Royal Oak (west of
Paddington) to Farringdon.
