Construction firm will oversee plans to increase size of Underground station by 50%

Mott McDonald has won the £509m contract to upgrade Victoria Underground station in central London.

The construction firm will be lead consultant for the detailed design through to construction of the station upgrade. A new ticket hall and entrance, seven new lifts, and nine new escalators will increase the station’s size by around 50%.

Mayor of London, Ken Livingstone, said: “The £509m redevelopment of Victoria Station is a great example of the huge investment being made to improve the Tube and transport across the capital. This expansion is essential to meet London's continued growth and development and to support the extra capacity on the Victoria line, due to be delivered by new trains and signalling system in 2013.”

Architect Scott Wilson undertook the early design contract, and Mott McDonald will progress the station designs.

Construction on the project is due to begin in 2009, with completion scheduled for 2014.
