The geology underlying King George V Dock is complex and highly variable due to the presence of multiple fault zones within the chalk and the Thanet Sands. Site redevelopment was made more complex due to the intricate geology on which the airport is built, and the need to restrict work to specific hours, often at night, to minimise passenger and operational disruption. Cementation Skanska was contracted to carry out marine piling work by the project’s main contractor, BAM Nuttall, as part of the first stage of the City Airport Development Programme. The ambitious project required the construction of a 75,000m2 concrete deck creating new ‘land’ on which to build the new terminal infrastructure and a parallel taxiway – the size of 11 football pitches. The airport infrastructure was in need of significant development to keep pace with anticipated future passenger demands. London City Airport, located just eight miles to the east of the City on the site of the old Royal Docks, has seen steady growth in passenger numbers since 2010.
