In Daxing, Beijing, China they are expecting a new airport terminal building to be errected by 2040.
The upcoming world's largest commercial aviation hub with seven runways will stretch over 700,000 m2 total floor area, to which they will add 80,000 m2 to form a ground transportation centre. The colossal project is being planned by the Zaha Hadid Architects.
The Zaha Hadid Architects design focuses on connectivity and dynamism of air travel, which can be observed thorugh "a sequence of inspirational inter-connected public spaces." The architects explain: "The flowing roof lines cover the large, column-free spaces and provide a sense of scale and orientation, welcoming the world to Beijing. All of the passengers' pathways within the central atrium, create a multi-layered civic space – a public square and a meeting public place for passengers from around the globe – at the very heart of the terminal."
The new design sees a compact building, minimizing distances between check-in and gate. Walking distances will hence be short, reducing requirements for shuttle trains or buses between the terminals, and the terminals will be able to host the maximum number of planes. On top of that, domestic and international passenger areas will be separated vertically to make the terminal building even more compact. Helping reduce the carbon footprint of the airport in the long-run is also the construction itself - instead of having an airport with many smaller terminals, this project sees many departure gates with a single passenger handling centre built in one terminal.
In 2019, the first phase of the project with high targets of environmental management and sustainability is expected to open, including four runways. On a yearly basis, these will be able to process approximately 45 million passengers. By 2025, the capacity will expand to 72 million passengers, and by 2040, when the project is set for completion, up to 100 million passengers will be able to enjoy the benefits of the new airport.
