ADP Ingénierie (ADPI), part of the French airport authority Aéroports de Paris (ADP), has won the competition to design Terminal 1 at Beijing's new Daxing Airport, beating both Foster + Partners, and a team composed of the China Civil Aviation Construction Group Corporation (CACC) and the Beijing Institute of Architectural Design. The design competition for the 700,000 square meter airport was announced in July 2011, with Beijing New Airport Construction Headquarters (BNAH) putting the submissions through "a long and rigorous selection process," according to ADP.
Foster lost out on the competition despite having designed Terminal 3 at Beijing's main airport, which at the time of completion in 2008 was the largest airport terminal in the world. However owing to the rapid rise in use of air transport in China that airport is already running at full capacity, necessitating the creation of another airport at Daxing, 60 kilometres south of Beijing.
