The fi rst half of the new station concourse will open at the end of this year, when the redevelopment of the existing station begins
the existing “as-installed” drawings and the unknowns that appear as areas are opened up,’ explains Quaiyoom.
Modular installation In the adjacent multi-storey car park, the entire fi rst-fl oor concrete fl oor slab has already been removed while the car park above has remained in use. In the newly created double-height space, away from the existing station, the western half of the new concourse is currently under construction. In the echoing, concrete gloom of the
empty car park, a team from contractor NG Bailey are hard at work installing a series of prefabricated services modules to form a new services spine. ‘There are quite a lot of modular services on this project because the logistical and programme constraints made them the most cost-effective option,’ says Quaiyoom. The modules are delivered to site complete with lengths of pre-insulated pipework and rows of empty cable trays already installed. They are wheeled into place on a series of temporary steel rails,

before being winched high into position beneath the bare concrete ceiling. Once the services installation is complete, work will commence on constructing the new concourse shops that are located beneath the spine. ‘The year 2012 is all about fi tting out this area,’ Quaiyoom explains. The south-north service spine links the
main plant room, located at the south of the site, with all 12 of the station’s east-west orientated platforms. Power, fi re alarm, passenger and voice announcements, CCTV and data cabling systems will all be distributed to the each platform. The spine will also deliver piped services, such as heating for waiting rooms and hot and cold water for staff washroom facilities. ‘The spine will deliver everything to
keep the station running,’ says Stephen Ashton, project director with responsibility for delivering design services for the construction phase for lead consulting engineer Atkins.
