The One Terminal project involves the complete redevelopment of Departure and Arrivals Level accommodation between the current two Terminals to combine the Airports Security and Arrivals functions and expand the Airports retail opportunities. The significant redevelopment is progressing on site in six phases to maintain the Airports operations through the peak summer season under separate traditional contracts lead and administered by D5. When complete by Summer 2011, the project will have created a combined Arrivals Area for both Terminals with new retail and refreshment offers, a combined 15 lane Passenger Search Area (PSA) by infilling a former two story space with a new floor, new lifts and stairs serving the new PSA and a significant walk through Duty Free Store, three sets of WCs, car hire units, fast food and other new retail concessions plus ancillary service and engineering accommodation for the Airport.
