HKIA T2 Foundation and Substructure Works

The Three Runway project was to expand the existing Hong Kong International Airport to meet future aviation growth and Hong Kong development. 

This project consisted of a series of infrastructure projects including a 650Ha land reclamation, a new concourse building and the expansion of Terminal 2 Complex connected by an Automatic Passenger Mover (APM) system and Baggage Handling System (BHS) to provide arrivals, departures and passenger services.

The Leighton-Chun Wo Joint Venture was responsible for the construction of the new Terminal 2 basement structure, a South Annex Building, future viaduct foundations and demolition works required for the expansion of the existing Terminal 2 building. 

The scope included utilities diversion, foundation works including diaphragm walls, bored piles, socketed H-piles and mini-piles, deep excavation, underground reinforced concrete structure, mechanical and electrical works, demolition works and airport alteration and additional works.

Key challenges for the project included working in a live environment, maintaining existing facilities and infrastructure.
