Overview:

The redevelopment of London Bridge Station is part of Network Rail's £6bn Thameslink upgrade programme to improve the north to south London commute by rail.

On completion, the London Bridge Station will provide customers with approximately 80 retail units and a concourse that has been described as 'the size of the pitch at Wembley'.

In total, fifteen platforms have been demolished and rebuilt, all the while keeping a significant number of train lines running among the live works.

Due to the tight programme and site constraints, Severfield had to develop and pre-manufacture a 'cassette' canopy system off-site. This included a steel framed cassette structure, roof, soffit cladding and lighting/speakers/first fix electrical. The cassettes were carried to site and constructed from transport frames. Each of the 1,100 cassettes are bespoke and supported from aesthetic plate columns, 'Y' arms and spine beams.

Severfield partnered with cladding specialist, Prater, for the development and delivery of the cassette philosophy and the construction methodology at London Bridge Station. The system enabled the canopy structure to be constructed quickly and gave immediate access to following trades.

Platforms 6-15 and associated concourse were opened to the public, according to programme, on 29 August 2016. The remaining phases of steelwork construction are due to commence in early November 2016. This will then complete the remaining 5 platforms, associated concourse and Tooley Street façade.
