Inaugurated in September 2019, Beijing Daxing International Airport (BDIA) is currently the largest air terminal in the world with its 47 square kilometres. The first terminal, Beijing Capital, reached full capacity in 2012. BDIA was constructed to relieve this pressure and transform the southern part of Beijing into a leading integrated international transport hub. One of Zaha Hadid’s last projects, the airport establishes a new standard for airline transport services and represents a catalyst for the economic development of Tianjin and Hebei province. The terminal is supported by a multimodal ground transport hub providing direct connections to the centre of Beijing via local and national rail lines, including high speed rail. The architecture of BDIA is based on a radial structure, articulated in 6 wings, or piers, extending out from a central multi-level nucleus that intuitively guides passengers toward departure, arrival or transfer areas. This concept makes circulation an ordering element of architecture that transforms the logistic spaces of the airport into an urban organism in which the city, or better yet, the movement of passengers and goods, flow inward, while the project flows outward to expose latent itineraries in the surrounding context.
