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.
A major milestone in the project was reached in September 2015 when the joint venture tunnelled through the final metre connecting the north and south tunnel schemes. Work was completed behind-the-scenes with no disruption to Tube customers, despite the fact that in certain places it was carried out less than 30cm away from operational Victoria line platforms.
The 300 metres of new tunnels will link the brand new North ticket hall with the existing South ticket hall which is being doubled in size.
A system enabling tunnel junctions to be supported without the use of traditional props was a winner at the 2015 VINCI Innovation Award.
The team devised an alternative method of support based on a retaining structure installed entirely on the inner side of the tunnel. This made it possible to do away with temporary shoring equipment at six points on the site which avoided the disruption of public access. It also contributed to improved worksite safety by reducing the need for equipment transport, handling operations and work at height.
