Excavation works on the Crossrail Canary Wharf Station, one of the largest on the route, nears completion this week.
Construction of Crossrail began in May 2009 with London mayor Boris Johnson driving in the first pile to create the station (See NCE 21 May 2009). In the following two years Canary Wharf Contractors has excavated down 28m below the dock to build the 256m long station box.
The station is being constructed “top down”, and so far engineers have installed over 1,000 piles, removed over 100M litres of water, excavated over 300,000t of material and poured over 375,000t of concrete.
The box must be completed before tunnel boring can commence with the tunnel boring machines expected to pass through the station in the second half of 2012.
