Project Highlight
Building up to full operations with 230 flights per day, the concourse can handle an additional 10 million passengers a year. The Mott MacDonald and Arup joint venture has been working on the detailed design of this project since June 2010, providing full multidisciplinary design and construction support. Aedas is the architect for the joint venture and has also worked closely with OTC Ltd on the planning of the concourse.
The concourse’ s timely opening demonstrates that a collaborative effort of client, contractor, lead design consultants and their sub-consultants, can bring about a successful outcome to a large capital works programme.
Design concept The design of the Midfield Concourse architecturally respects and complements the existing Terminal 1( T1), while incorporating the latest thinking in aviation, passenger expectation and sustainability.
Passengers will be able to experience HKIA’ s latest ambience experience with more landscaping and fresher colours than ever before. At the APM concourse, passengers alighting the train are presented with an impressive 8m × 40m long blue cast glass wall by artist Graham Jones. On arrivals, a complementary 8m × 29m red cast glass wall welcomes passengers. They are part of a magical space which glows with light: adjacent big green walls with waterfalls reference the natural landscape of the Hong
Kong New Territories.
The undulating single-span roof of the concourse adopts a diagonal truss structure with curving north-facing roof lights to bring natural light deep into the heart of the building. At the centre of the departures level sits the retail hub, flanked by the north and south halls. Passengers can look both ways towards all the boarding gates, visible beyond the retail stores and food outlets. It is this intuitive legibility that provides a comfortable setting for a relaxed shopping and dining experience.
Sustainability To maximise efficiency and sustainability, we have introduced more than 35 green features, including low-energy lighting systems, high performance glazing panels, solar shading and north-facing skylights to maximise natural lighting while reducing solar heat gain and saving on air-conditioning.
The concourse adopts an environmentally responsive building form, with its roof shape and glazed facades optimised based on the building’ s orientation. The roof has an asymmetrical cross section with a deep protective overhang to the west to minimise solar heat gain. As the concourse’ s axis is offset from true north and south, the aspect of the skylights sit at a skew to the main orientation of the roof, to face north to maximise natural lighting.
Recycled water is used for water-cooled chillers of the air-conditioning system and
seawater for flushing. More than 1,200 m 2 of solar panels are installed on the roof to harness renewable energy.
The project targets to become one of the first few buildings to receive the BEAM Plus Gold Rating from the Hong Kong Green Building Council.
Building Information Modelling( BIM) The Midfield Concourse is AAHK’ s first facility to be developed with BIM, enabling use of innovative 3D tools such as wind flow modelling, air traffic control sightline and walk through checks. These 3D tools and implementation of BIM facilitated the coordination of all disciplines in a synchronised manner, while preventing and resolving coordination clashes. The application of BIM on this project won Bentley’ s Be Inspired BIM Awards 2011 and Autodesk’ s Hong Kong BIM Awards 2013.
