London Underground has put out a tender notice for contractors for the extension of the Northern Line from Kennington to Battersea, worth between £400m and £600m.
London Underground say they are looking to pre-qualify “those entities best able to deliver this complex project and bring innovative ideas forward to identify and deliver significant cost, risk programme and other benefits.”
The work includes around 3,300 metres of new tunnels, including over-run tunnels and ventilation shafts, as well as new stations at Nine Elms and Battersea.
Nine Elms is undergoing a separate regeneration aimed at creating 16,000 new homes.
A single company or consortium is being sought.
The project also includes development of design and design assurance for civil engineering, tunneling, drainage and systems fit-out.
Utility diversions, enabling works and project management will also come under the winner’s remit.
London Underground continued: “This complex and high profile project is to be carried out in one of the busiest areas of London, in the vicinity of road junctions, through routes for traffic and involving one of the busiest underground lines.”
“Impact of residential areas, listed buildings and other significant heritage properties will need careful and sensitive management whilst minimising disruption to neighbours, passengers and the operational service of the northern line.”
