VICTORIA STATION UPGRADE

Client: London Underground

Victoria Station is one of the busiest in London and is used by over 80 million customers each year – more than Heathrow Airport. The Taylor Woodrow BAM Nuttall joint venture is upgrading the station which will increase its size by 110 per cent and deliver step-free access for the first time in its 147-year history.

The project includes re‐modelling the existing station, doubling the size of the existing Victoria Line (South) ticket hall, constructing a new Northern ticket hall and construction of 300m of interconnecting tunnels. These include an escalator barrel, 5 connections with the existing station and an underpass of the District and Circle (D&C) Line. A full M&E fit out completes the works package with 9 escalators and 8 lifts providing step‐free access throughout the station.

The tunnels were constructed using modern sprayed concrete lining techniques at relatively shallow depth. Jet grouting was used to stabilise the ground and expel the groundwater from the tunnel horizon. An innovative combination of permanent and temporary works was developed to allow the formation of an underpass beneath the District & Circle Line which connects the two sides of the tunnel network together.
