Existing Structure & Location:
Shepherd’s Bush Station was originally opened in 1900 as the Western terminus for the Central London Railway.
It was designed and funded by Westfield Group as part of a section 106 redevelopment contribution and construction project managed by Capita Symonds. It included the provision of an integrated bus interchange and the reconstruction of the London Underground Central Line Station.
Scope of Works
- Externally the project was to demolish the existing single storey structure but thereafter, extend a further 3 storeys below road level, whilst maintaining the ‘day to day’ operation of this important Central Line transport hub.
- Constructed of brick, clinker slab & beam floors, John F Hunt were required to maintain the structural integrity of the clinker slab and also provide a protection / crash deck with waterproof membrane to the existing concourse.
- Adjacent to, but below the ground level demolition cut line, it was necessary to maintain the critical station services through out the duration of the demolition works.
- All works were subject to stringent noise controls due to the close proximity of residential properties and retail businesses. Accordingly agreement was reached with both Hammersmith, Fulham Council and local resident groups on acceptable levels.
- During the entire demolition process the main electrical supplies, signaling & other London Underground assets had to remain fully operational.
- Demolition of the existing Station, Ticket Hall and Concourse all formed part of the contract again in a live operational LUL environment.
- Manual dismantling of Escalators.
- Machinery used included a 40m Jib, Tower Crane, various Brokk Robotic demolition machines equipped with both Hammer and Concrete Cracking attachments. Diamond Drilling, Sawing and Bursting techniques were employed to ensure a clean separation between the retained and redundant structures.
- An exceptionally condensed programme driven by the opening of the new Westfield Shopping Centre necessitated demolition being carried out on a 24/7 working pattern.
- Erection of 8 metre high Acoustic Screen.
- Extensive LUL trained & approved supervision.
- All works had to be carefully coordinate with the main contractors sequence and deliveries, this being critical to the construction phase and opening of the new Station facility.
- Staff had to undertake LUCAS access, fire watchman & SPIC (Site Person in Charge) training which was undertaken prior to commencement.
- Internal structural ties installed to prevent collapse.
- Special measures and monitoring around lower basement level LUL signalling equipment.
As a result of this and other Rail related Projects John F Hunt were presented with the Morgan Est Supply Chain Award for Innovation.
