T.Y. Lin International (TYLI) provided Civil & Structural Engineering Services for the alternative design of Singapore’s Changi International Airport, Terminal 3 development. The TYLI team optimized the structural design of the 64,500-square-meter roof structure above the departure hall by maximizing the use of abundant natural light.

Changi International Airport, Terminal 3 has seven levels, four above ground and three below ground. The total gross floor area is 427,184 square meters, with a total of 28 aerobridges and supporting infrastructure, eight of which were designed to handle super-jumbo aircraft.

Project Highlights:

  • The main roof structure of Terminal 3 incorporates 916 skylight openings, each measuring 12.5 square meters.
  • The amount of direct sunlight is regulated through the use of louvers suspended above and below the skylights.
  • By maximizing the open plan design of the Terminal 3, travellers can conveniently navigate the terminal with minimum dependence on signage.
