Crossrail Canary Wharf Station
Canary Wharf, London, UK · 2009–2018 · £500m (2009 prices)
The judgement call
Account-gated at launchDecision to build within the dock using a cofferdam rather than draining the entire dock due to high risk and cost. - Successful integration of silent piling technology for urban construction.
Key engineering challenges
Constructing a large station box within 9m of dock water, requiring a substantial cofferdam. - Implementing a tied-back retaining wall system in challenging marine conditions. - First large-scale application of Giken silent piling technique in the UK to minimize noise and vibration. - Managing significant environmental risks associated with working in an active dock.
