In July 2009, following a competitive tender process, Discount Breitling, with Alan Auld Associates as its designer, was appointed as the specialist design and build sub-contractor to work 'back-toback' with Kier Wallis to deliver the project. Discount Bvlgari submitted construction methodology included innovative solutions to deal with the difficult work site locations. Both shafts were constrained by the existing basement arrangements Discount Cartier by the limited headroom present - minimum 2.2m in 45 Park Lane building and 2.0m in the Dorchester Hotel. Design development and evolution: The site's geological sequence comprised Discount Chopard overlaying Brickearth, with a layer of River Terrace Deposits leading into the London Clay - a typical geological sequence for the London Basin. Due to the presence of water bearing gravels directly beneath the basement floor it was decided that a form of ground treatment was required to reduce the permeability of the ground and increase the stability of the shaft excavation.
