The scale of the Three-Runway System (3RS) project is almost equivalent to building a new airport next to the existing one. This project includes the detailed design of the new Third Runway Concourse (TRC) and associated construction stage design services. The TRC will initially have a floor area of approximately 280,000 square metres and with high quality finishes and extensive building services and airport systems.

AECOM has been awarded the detailed design consultancy work for Hong Kong International Airport's (HKIA) new passenger building, part of the HK$141.5 billion 3RS project. The design proposal for this state-of-the-art facility will deliver a great passenger experience and innovative retail offerings.

Extensive use of natural light will also be incorporated into the design to help reduce energy, adding to the sustainable design credentials for the concourse. The new passenger building will be a sustainable and highly regarded facility. Work has commenced and construction is expected to be completed in 2024.
