The project will increase the capacity and utilisation of the existing Pier 5 as part of Gatwick’s aim to increase its passenger numbers and become London’s Airport of choice.

It includes construction of a new departures corridor on top of the existing pier to eradicate cross flows of arriving and departing passengers.

Several aircraft stands will be reconfigured to more efficiently accommodate both narrow and wide bodied aircraft.

Carillion will also install some stands, along with new fixed links, nodes and vertical circulation cores, to ensure that every aircraft parking position can be served without the need for passengers to have to go outside.

The gaterooms for departing passengers will be reconfigured to suit the new stand layout and provide Gatwick with a flexible layout that can cater for both short haul and long haul operations.

The work is due to be completed by summer 2014.

Doig+Smith will carry out contract administration and cost engineering support for the Pier 5 reconfiguration project at Gatwick Airport.

The job comes from the £1.2bn Gatwick major projects framework which Balfour Beatty, Bouygues, Carillion, Costain, Mace, Morgan Sindall, Laing O’Rourke, Vinci, Volker Fitzpatrick and Willmott Dixon.
