The station has suffered from severe congestion for some time, sometimes leading to station closures to limit overcrowding. As passengers numbers are expected to grow in future years, LUL wants to upgrade the station to cope.
The station upgrade is required to be completed as early as possible to conicide with line upgrades.
The works comprise civil engineering, fit-out and services installations to provide:
new subsurface Northern ticket hall with ground level entrances,
extension to existing subsurface Southern ticket hall,
new subsurface tunnels to provide access to existing platforms
new lifts to provide step-free access between street, ticket halls, concourses and platforms
utility diversions and sewer strengthening works
infrastructure for Cooling the Tube Programme and subsurface traction substation
potential modernisation and integration of other station areas
The contract is listed on the Official Journal of the European Union. Firms have until the beginning of February to express an interest.
