Bank Underground Station Capacity Upgrade (BSCU)

To support its network capacity upgrade, London Underground is undertaking a major capital project to expand Bank underground station. This £642m scheme will improve the capacity of Bank station, and reduce journey times and congestion in the Northern Line, Central Line, Docklands Light Railway (DLR) and interchange areas within the Bank-Monument station complex.

The Bank and Monument Tube station complex is located in the heart of the City of London financial district and is the fourth busiest interchange station on the Underground network with 96,000 passengers during the morning rush hours (1.17 billion passengers a year), which is set to increase by 40%.

Bank is served by six lines (Northern, Central, Waterloo & City, and at the Monument end of the same station 

complex, the District and Circle, as well as DLR, for which Bank is the main central London terminus. The disused King William Street Station lies to the south of the site.

The project will be delivered under the heart of the City of London, one of the most expensive areas of real estate in the world while the station remains operational and with minimum impact on adjacent structures and the City’s everyday life. The works involve specialist tunnelling, civil engineering, high voltage power engineering, communications systems, lift and escalator works, as well as building and M&E work.

The Bank Station capacity upgrade project has benefited from London Underground’s pioneering use of the Innovative Contractor Engagement (ICE) procurement process which was designed to select the best principal contractor (Dragados was appointed in 2013) and supply chain, including Cleshar, and to incentivise innovation, placing value at the core of the project from the outset.


BCSU’s customer team conceived and developed ICE to ensure that all good and relevant ideas proposed during bidding were rewarded, developed and implemented in the project. All the teams involved in this process were actively engaged throughout the design process, leading to the optimum solutions that were ‘Best for Bank’. The successful execution of ICE on Bank Station has provided London Underground with a platform for future development which addresses the historic challenge of how to control costs, accelerate the works and reduce the impact on the travelling public.
