The design and build contract involves boring and lining 3.3km of twin tunnel between Kennington and Battersea, with internal diameter of 5.2 metres. The contractors must also build two stations: one at Battersea and one at Nine-Elms. Over the next 20 years, approximately 16,000 homes are expected to be built in this vicinity.
London Underground confirmed the joint venture as its preferred bidder on Friday. Ferrovial/Laing O’Rourke was preferred to the Balfour Beatty/BAM joint venture, which had also made it through to the final stage of bidding. London Underground expects to award the contract next month.
The aim is to start construction in spring 2005 and open the line by 2020.
A public inquiry to consider London Underground’s Transport & Works Act Order application was held at the end of 2013. A decision on the application is then expected by the secretary of state for transport in the autumn of 2014.
