Hong Kong-Zhuhai-Macao Bridge Passenger Clearance Building (PCB)
The Passenger Clearance Building (PCB) of the Hong Kong-Zhuhai-Macao Bridge Hong Kong Port is using smoke vents and failsafe linear actuators from SE Controls Asia Pacific to help protect passengers and officials by ensuring escape routes are kept clear of smoke should a fire occur in the 90,000 sq.mtr structure.
The Hong Kong-Zhuhai-Macao Bridge (HZMB) is 34 miles (55 km) long, which links Zhuhai and Macau to Hong Kong and provides a strategic southern connection between the 11 cities of the Greater Bay Area Megapolis by linking the West and East Pearl River Delta in China.
The PCB is part of the port area, which is constructed on an artificial island of around 150 hectares that has been reclaimed from open waters. Its undulating modular roof design and glazed curtain walled structure and energy efficient sustainable construction enables the building to infuse natural light and fresh air as well as generating much of its own energy and water.
Its smoke control system is equally advanced and incorporates almost 2,000 smoke vents into the design, which are located into three individual smoke zones if a fire should occur and enable escape routes to be kept free of smoke.
Every exhaust smoke vent in the PCB is operated by two SE Controls SEPO pneumatic fail-safe actuators and equipped with fail-safe locking catches. In the event of a fire the system automatically opens the smoke vents to release smoke and heat from the building but is designed to also operate if there is a failure in either the mains power or the pneumatic system.
