The Canary Wharf underground railway station is one of the largest and most complex structures on London’s £2.75 billion Jubilee Line extension project.

Royal Haskoning began working on the underground station in 1991 and created a large design team dedicated to the project. The design team incorporated the client’s requirements, which were embodied in many thousands of drawings, and liaised with both client and architect to produce a structure of world-class status.

The station was constructed in one of the old West Indian Docks between Canary Wharf and Heron Quays, in London’s docklands. Protecting the early-19th century dock walls and the stability of the nearby tower blocks was vital when considerations were made for both design and construction. In this regard, extensive investigations were carried out to examine the effects of ground movements caused by construction of the stations, with particular attention to the effects of lowering the groundwater.

The station contains a large passenger access walkway suspended on high-tensile steel cables from the underside of the roof. The basic structure comprises a reinforced concrete box approximately 30-m wide and 300-m long, requiring the construction of 30-m deep diaphragm walls. The single island platform at low level will be connected with the ticket hall above by means of escalators, (twenty in total) to accommodate the very large numbers of commuters arriving and departing each day from the Canary Wharf business district.

Royal Haskoning provided the structural and civil engineering design for the Canary Wharf underground station to be realized.
