The project will be delivered by Lakesmere’s recently established Reading office. It brings the total number of Crossrail projects with which Lakesmere is involved to four.
The new station’s platform edge screen system presents both design and installation challenges, Lakesmere said, with one tunnel curved both on plan and in section and the additional considerations of working within the restricted underground environment.
Lakesmere’s scope of works includes the supply and installation of the main steelwork across two station platforms totalling nearly 500 metres, prefabricated into trusses up to 6 metres long. Once delivered, the steelwork trusses will be lowered by tower crane through a restrictive mole hole to level -4, before being distributed via the station’s passenger tunnels to the workface. The steelwork trusses will then be lifted into place and suspended from the concrete tunnel soffit, with the remainder of the works fixed back to the steel.
Other works include a cable management system, GRC isolating panels and an over-track ventilation system, comprising of precast concrete panels, horizontal support steelwork and vertical galvanised steel lining panels. Architectural finishes, including aluminium grilles and light box units to the platform side of the works, will be installed during a second phase of works.
Work at the Tottenham Court Road station is expected to start in summer 2015, with two further site visits completing in 2017, before the station is open to the public in August 2018.
Lakesmere is also already on site at other Crossrail stations across London including Canary Wharf, Liverpool Street and Whitechapel.
