The Beijing New Airport lies on the north bank of the Yongding River, 46 km south of Tian’anmen Square. It was officially named as "Beijing Daxing International Airport" in September 2018. According to the master planning, the long-term capacity of Daxing Airport is more than 100 million passengers per year, divided into two terminal areas of north and south. The north terminal building constructed in this period will meet the capacity of 45 million passengers, and can drive the south satellite terminal to be built later, that can reach a capacity targeting at 72 million passengers of the north terminal area.
There is a traffic network of "five vertical - two horizontal" outside the airport and concentrated in front of the terminal, which consists four expressways and three rail lines currently.
In face of the super large design capacity, the terminal adopted the double-deck departure viaducts and the double departure halls layout for the first time. The arrival function is also divided into domestic and international floors, which provides necessary space for the layout of the process facilities. The aircraft was connected at five radiation concourse piers, a good balance was achieved between the number of contact stands and the walking distance of the farthest gates.
The outer contours of six piers of the terminal building and the multi-service building are positioned by an outer circle and six intersecting circles, and the five waiting lounge piers cut the apron by four parts. With the ends of the piers enlarged, a total of 50 boarding bridges were deployed, connecting 79 contact stands. Among the five piers, one on the south side is international and four on the east and west sides are domestic. The arrangement of international aircrafts placed at the centre and domestic on both sides corresponds to the internal functional structure of the terminal divided into the east and west zones.
The conventional check in hall was in the 4th floor. After checking in, the international passengers went straight, via a bridge to the immigration frontier, while domestic passengers on both sides go down to the security check point on the third floor. The north edge of the third floor connects the lower viaduct, which is the fast-track of domestic departure, the south area of the third floor is international waiting lounge. The four side piers with two commercial plazas on the second floor are domestic departure and arrival mixed flow zone, as well as the domestic baggage reclaim hall was the same floor as well. The main passenger functions on the first floor include the international inbound check at the central area, baggage claim hall, metres and greeters hall, domestic remote departure lounge, long-haul waiting passenger service areas (to be open later), as well as the VIP zone and hourly hotels, etc.
The main function of two underground floors of the terminal building is to connect 5 rail transits, including 2 high-speed trains and 3 lines of city metro, which were expected to bear 30% of the total passenger volume of the airport. The airport terminal and the railway stations were integrated designed, their functions were mixed at the exchanging hall. With the approaches of shortening the connecting distance, deploying airport departure facilities at the station, providing adequate lifts and elevators to upper floor, etc., a highly convenient passenger connection was arranged between the rails and the airport.
The roof is the largest component of the terminal building. It adopts steel frame structure with metal plate enveloping the inner and outer surfaces, covers whole internal space and the road curb in front of the terminal. The central part of the roof is one structural unit, supported by 8 C-shaped columns in the middle with other 12 supporters at the top of commercial cabins.
The large span space of the terminal reduces the floor support, making the passengers passing below more fluent and have a wider view, and the floor layout is freer, which meets the terminal's specific requirements of orientation, mobility, and flexibility.
The tune of white surface, curved shapes and lines makes the interior theme, together with the ceiling and skylight creates a vibrant and dynamic public space.
