Singapore Tests Robot Excavators to Boost Construction Safety

Construction sites in Singapore are getting safer thanks to excavators and compactors that operate themselves using artificial intelligence and sensors.

JTC Corporation and Kajima Corporation are testing the autonomous equipment at the Bulim Autonomous Yard in Jurong Innovation District. An operator assigns tasks and sets digital boundaries, then the machines work independently while staff monitor remotely and step in only when needed.

The pilot aims to cut the number of skilled operators required by half while keeping workers away from moving machinery and hazardous conditions. With 800 hectares of earthworks projects planned over the next five years, Singapore sees major potential for scaling up this technology.

What makes this especially practical is the retrofit approach. Instead of replacing entire fleets, contractors can upgrade machines they already own with autonomous kits.

The autonomous excavator uses technology from Gravis Robotics, while the compactor runs on Kajima's A4CSEL system in its first deployment outside Japan. This strategy lowers the cost barrier and makes it easier for more construction companies to adopt the technology.

Safety features include geofencing to keep machines in designated areas, LiDAR sensors to detect people and obstacles, and emergency stop controls both onsite and in remote control rooms. JTC is working with the Ministry of Manpower to develop comprehensive operating guidelines before wider rollout.

The partnership includes the Housing & Development Board and the Public Sector Science & Technology Policy & Plans Office, creating a coordinated government approach to construction innovation. Local contractor Kok Tong Construction and equipment provider Tractors Singapore Limited are helping retrofit conventional machinery and train Singapore-based operators and engineers.

The Ripple Effect

This pilot could transform how Asia builds infrastructure. By documenting lessons learned and developing safety frameworks, Singapore is creating a roadmap other countries can follow.

The team plans to test autonomous bulldozers and dump trucks in 2027, working toward coordinated fleets of construction equipment that communicate and work together. That vision requires advances in data interpretation, digital planning, and system integration.

JTC plans to invite more public agencies, contractors, equipment makers, research institutions, and tech companies to run trials at the Bulim yard. The site is becoming a proving ground where technologies get tested and refined before going mainstream across Singapore's construction industry.

Machines that keep workers safe while building faster is progress worth celebrating.
