Singapore will implement a major digital and robotics upgrade at Changi Airport Terminal 3 to modernize passenger services and operations.

The overhaul is critical as the airport seeks to manage growing passenger traffic and refine automated systems before the launch of Terminal 5. By using Terminal 3 as a trial site, authorities can identify technical friction points in a live environment before scaling them to the new terminal.

Acting Transport Minister Jeffrey Siow announced the initiative on April 29, 2024 [2]. The upgrade will integrate advanced digital technologies and robotics into the terminal's infrastructure. Specific improvements include the introduction of automated toilet cleaning, and enhanced self-service check-in systems [1].

These robotics projects are designed to function as pilot programs. Siow said, "We will introduce more digital technology and robotics for self‑service check‑in and toilet cleaning, which will serve as test‑beds for the upcoming Terminal 5" [1].

The government is preparing for the procurement phase of the project. The tender for the Terminal 3 upgrade works is scheduled to be issued in the second half of 2026 [1].

Siow said the upgrade will focus on digitalisation and robotics, noting that some of these initiatives will serve as pilot projects for Terminal 5 [1]. The strategy aims to maintain Changi's competitive edge as a global aviation hub by reducing reliance on manual labor for routine maintenance and passenger processing.

This phased approach allows the airport to iterate on robotic efficiency and user experience. The integration of these technologies is expected to streamline the passenger journey, reducing wait times and improving facility cleanliness, while providing the data necessary to optimize the layout and operational flow of Terminal 5.

“The upgrade will focus on digitalisation and robotics, some of which will be pilot projects for Terminal 5.”

This initiative signals Singapore's strategic shift toward an automated aviation ecosystem to counter labor shortages and increase operational efficiency. By designating Terminal 3 as a test-bed, the government is mitigating the risk of large-scale technical failures at Terminal 5, ensuring that the next generation of airport infrastructure is vetted through real-world passenger data and robotic performance metrics.
