Expanded Piling picks up Isle of Dogs station coffer dam job
Laing O’Rourke subsidiary Expanded Piling this week scooped one of the contracts to create the coffer dam for Crossrail’s Isle of Dogs station at London’s Canary Wharf. Expanded will create a massive cofferdam using 1.2m diameter tubular steel piles inside which the 260m long, 30m wide and 22m deep station box will be constructed by lead contractor Canary Wharf Contractors (CWC).
CWC is a subsidiary of client Canary Wharf Group. The station will be one of the first structures to be built as part of the £16bn Crossrail scheme.

The basement shell has to be in place by the time tunnel boring machines reach Canary Wharf in four years time. The contract announcement, revealed at NCE’s Crossrail conference on Tuesday, coincided with the publication of Transport for London’s (TfL’s) £9.2bn budget for 2009/2010. This identifies the start of work on Isle of Dogs station as one of a number of key milestones for the next year.
TfL’s plan also includes the completion of the Jubilee Line upgrade and the start of the redevelopment of Tottenham Court Road Underground station. Reduced revenue projections from fares as a result of the recession and the drain on TfL’s resources caused by the collapse of Metronet means that some TfL projects planned for 2009/10 have been cancelled or deferred.
The Greenwich Waterfront Transit scheme will be cancelled and work at some Tube stations will also be deferred. This includes the project to install step free access to the Circle and Metropolitan lines at Baker Street.
