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


CAPE has overseen the development of key airport infrastructure at Singapore Changi Airport since 2007.

In May 2018, CAPE and its partners won a multi-year Master Civil Consultancy for the future Terminal 5 (T5) buildings. The consultancy includes the design of infrastructure such as taxiways, aircraft parking stands, roadways and drainage systems, as well as the connections for utilities to the terminal buildings.

CAPE is also the lead consultant for the ongoing three-runway airfield engineering project for Changi East Development which encompasses T5. It is involved in the airport master plan, airfield and engineering design, as well as the functional review of the new terminal.

Changi East is the next phase of development for Changi Airport. When completed, the project will significantly augment the airport’s handling capacity to 135 million passengers per annum.

CAPE also worked with CAG to successfully launch Terminal 4 in October 2017. The project involved feasibility studies, revision of the master plan, terminal concept design, and detailed airfield engineering works.

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.
