Name and Location
Hong Kong International Airport (HKIA) expansion project, China.

Client
Hong Kong Airport Authority (HKAA).

Project Description
The recommendation is for a third runway to be located north and parallel to the existing two runways.

Development of the three-runway system will involve:
• land formation of about 650 ha to the north of the existing airport island, of which about 40% falls in an area of contaminated mud pits;
• construction of a third runway, related taxiway systems and navigation aids, and airfield facilities;
• construction of the third runway aprons and passenger concourse;
• expansion of the existing Terminal 2;
• extension of the automated people mover and the baggage handling system;
• improvement of the road network in the passenger and cargo areas;
• new landside transportation facilities, including new car parks;
• a greywater recycling system at the proposed airport expansion area, with a capacity of about 15 000 m³/d;
• the necessary modifications to existing marine facilities, including the underwater aviation fuel pipelines and the 11 kV submarine cable between HKIA and the off-airport fuel-receiving facilities, as well as to sea rescue facilities and navigation aids; and
• any other modification, reconfiguration, and/or improvement of the facilities on the existing airport island as a result of the third runway.

The expansion will allow for 620 000 flight movements, enabling more than 102-million passengers and an estimated nine-million tonnes of cargo to pass through the airport every year.

Value
The project is estimated at $11.1-billion.

Duration
The entire project is expected to be commissioned in 2023.

Latest Developments
Mott MacDonald is designing the third runway, infrastructure and concourse at HKIA.

As lead consultant, Mott MacDonald is designing the scheme for the third passenger concourse and runway, which will be created on a reclamation platform north of the existing airport island.

This includes designing all associated taxiways, roads and tunnels, stormwater culverts and drainage, ancillary buildings and utility services, as well as airfield systems, such as aviation fuel supply, airfield ground lighting, high-mast lighting, fixed ground power, communication and control systems, fire services and cable ducting systems.

The company will also design an automated people mover and baggage handling systems for the new concourse, which will provide about 60 bridge-served stands and 40 remote stands.
