St George Wharf is a landmark riverside development spanning across seven acres, near to London’s Vauxhall Underground Station. Initially rising 22 storeys, but now with the addition of the 48 storey Tower, St George Wharf is the tallest sole residential building in the UK.
The 93,000-square-metre (1,000,000 sq ft) mixed-use development comprises over 1,100 apartments, as well as offices, retail units and restaurants.
Civil and structural services were provided for a 12-storey residential block, with commercial space at street level and double height penthouses, which sits within Phase 1 of the development.
The block is built directly over the Victoria underground line, which limited foundation options. Two metre diameter piles were threaded between the tunnels and driven through the London Clay to the Thanet Sand at over 60metres depth. The building is then supported on 2.5-metre-deep ground beams spanning between pile positions.
The project also consisted of a pedestrian bridge passing below Vauxhall Bridge as part of the government’s plan to provide a continuous pathway along The Thames.
Other areas of involvement included drainage strategy for the site, and flood risk assessment.
