Description:
This Car Park for Manchester Airport situated between Styal Road and Shadow Moss road commenced in February 2014 and was completed in December.
This was one of the first projects undertaken by Galliford in a new framework agreement with Manchester Airport Group. A wet autumn and early winter period had left the site sodden, causing many problems and eventually leading to the requirement for ground Stabilisation to be introduced.
