Airport Planning & Engineering

Planning airport capacity requires a fine balance. Over capacity may result in under-utilised funding and lower operating margins, while under capacity may lead to lost opportunities and public confidence.

Changi Airport Planners and Engineers (CAPE) builds airports for the future. It takes a long-term approach to design and capacity planning, aimed at delivering service quality without compromising on sustainable growth and room for expansion.

Succcess Story


Since 2007, CAPE has overseen the development of key airport infrastructure, such as aircraft pavements, runways and taxiways, and airfield drainage at Singapore Changi Airport.

In 2011, CAPE was engaged to replace The Budget Terminal with the new Terminal 4. This includes feasibility studies, revision of the airport master plan, terminal concept design, and detailed airfield engineering works. The team worked with CAG to ensure that when Terminal 4 opens in 2017, it will have the flexibility to cater to the growing regional travel segment through efficient terminal operations.

CAPE is also the lead consultant for airfield engineering for the Changi East Development which encompasses Terminal 5. It is involved in the airport master plan, airfield and engineering design, and functional design review of the future terminal. The new development will also have facilities to support airfreight and air express operators, and MRO activities.

CAPE was formed in 2007 to share the experience of developing Singapore Changi Airport with the world. As a leading airport planner, it has worked with airport operators to execute nearly 60 projects in more than 20 countries around the globe, covering a broad spectrum of services including master planning, airport engineering, terminal design and project development.
