Battersea station on the Northern Line Extension could be mothballed or result in a court battle over £240M in additional costs, according to Transport for London director of major projects Stuart Harvey.
The costs relate to significant changes to the over site station development at Battersea on the Northern Line Extension, which have resulted in changes to the design and construction of the station box.
Harvey said during a budget and performance committee meeting with the London Assembly that TfL is having sensitive conversations with the Battersea Power Station developer and its contractor, Ferrovial Laing O’Rourke.
A clearer picture on the actual costs is expected in December, according to Harvey, but he could not rule out taking the developer to court to recover the costs. He also said that not opening the station when the line is completed in 2020 is also an option.
The new Northern Line stop at Battersea is part of the extension of the Northern Line from Kennington and also includes a new station at Nine Elms. The £1.2bn extension is being privately funded by the Battersea Power Station developer and business taxes.
“Changes have put a cost pressure on the development,” said Harvey. He added that TfL is looking at value engineering solutions to these costs and to the time pressures it has placed on the project.
Harvey said that he was still hopeful that the scheme would be delivered by the end of 2020 but he described that date as “extremely challenging” and he cannot give a completion date with certainty for another six months.
Harvey said that he would have a clearer picture on the commercial costs and implications of the changes in December this year.
He said that elsewhere on the project good progress was being made with the tunnel boring machines being 75% of the way through the project and have passed the Nine Elms Station. He added that work on the step plate junction at Kennington is progressing well and is on target to be ready for the major work planned over Christmas.
