Starting later this summer, the work for Network Rail will involve excavation to the west of the suburban platforms and is expected to take just over a year. Kier, Carillion and Morgan Est were also in the running.
Taylor Woodrow will link the new yard to the existing tunnel underneath platforms one to eight, providing logistical access for station operations such as onboard services, waste -removal, catering and retail deliveries.
Developer Argent, which is tackling the broader regeneration of the area, will build the access ramp and loading bays. A new access road will be provided either from Pancras Road or Goods Way. The contract is part of a £400 million programme to transform King’s Cross station by 2013.
Later this year tenders will be invited for the £18 million revamp of the main train shed roof as well as a £22 million job to modernise platforms.
