Passenger Clearance Building

- Location: Hong Kong, China
- Architects: Aedas, RSHP
- Time: June 2018
Located on a 150-hectare, newly reclaimed artificial island northeast of Hong Kong International Airport, the Hong Kong-Zhuhai-Macao Bridge (HZMB) Hong Kong Port (HKP) is Hong Kong’s entry point to the new HZMB (with approx. 30km long Main Bridge). The centrepiece for HZMB HKP, the Passenger Clearance Building (PCB) handles clearance for passengers travelling to and from Hong Kong. As well as providing a hub for transport and travel, PCB also offers a striking and iconic focal point for the development.
The main feature of the building is its wavy roof, and this roof can be seen as a basic rectangle SHAPE being bent, or it can be realized by DISPLACEMENT.
Located at coastal area of Hong Kong, the structure’s ability to endure typhoons, monsoon rains, high humidity while maximising daylight through the roof skylights must be simulated and experimented using MATH approach during the design process. The wave-like roof is the most efficient outcome of this math approach.
In addition, to help reduce the cost of the roof’s challenging freeform geometry and to facilitate speedy construction, MATH approach is also adopted to produce repetitive units, taking into account the maximum size of each unit for easy transportation and installation and the smallest number of units.
The shape of each unit is closely related to its structure. The continuous beams are allocated at both side of the wave-like roof while the loads are transferred to the columns standing in the middle of each unit through four inclined steel beams.
