The project consists of the remodeling and upgrade of the Departures Terminal at Perth Airport, which is the fourth largest airport in terms of passenger traffic and is the winner of the Australian Airports Association award for Australian Major Airport. The T1 International departures expansion and domestic facilities project,is a complimentary project designed to deliver additional capacity for international departing passengers and to accommodate domestic operations (departures/arrivals) in the terminal building. The design also includes a number of flexible "swing gates" capable of catering for domestic or international traffic. The project works involve the construction of a new single level pier at the southwestern end of the current international T1.
