Project Details

Hong Kong International Airport T1 Annex Building


Hong Kong


The Airport Authority Hong Kong


Hong Kong International Airport (HKIA) is one of the world's largest passenger terminal buildings (the world's largest when opened in 1998) twenty‐four hours a day. Flights are operated by roughly 90 airlines to over 150 cities across the globe, and in 2009 it was the 13th busiest airport worldwide in terms of passenger throughput, and was the second busiest airport in the world of cargo traffic.

Due to the continuous growth in demand, the core facility, Terminal 1 (T1) of HKIA, had been expanded to the North of T1 for the purpose of additional processing capacity. The construction of T1 Annex Building (T1A), was one of the key components of the Expansion, which covered one check-in island to accommodate over 40 additional check-in counters with self-service bag drop facilities, two additional baggage reclaim carousels, an additional early bag storage1 (“EBS”) facility, and additional passenger facilities. It included a 200-meter-long and 28-meter-high sky bridge.

In this project, the architect and consultant has put the smoke extraction system to the terminal buildings in terms of measuring smoke control under any fire emergency, which incorporated of 115 smoke vents. The electro-pneumatic control panels contain fully monitored battery backed secondary power supplies to ensure full operation in the case of mains failure. The system is designed to failsafe, i.e. in case of all power supply failure or disturbance in pneumatic air supply, the smoke vents are designed failsafe to open. The system communicates with Fire Alarm System and providing ultra-efficient smoke extraction.
