Description
Bank Station is a London Underground station located in the City of London financial district. It is a key interchange served by five existing lines. The Bank Station Capacity Upgrade (BSCU) comprises the construction of new tunnels adjacent to and connecting with the existing tunnels. Defects surveys of the LU existing facilities predicted to be impacted by the BSCU works had to be carried out before construction started. All existing facilities expected to be within the 1 mm settlement contour were inspected for defects.
