Tunnel Boring Machine (TBM)
Precision-guided mechanical excavation for complex underground environments
Advanced Technology
Key Capabilities
Precision Steering
Millimetre-accuracy guidance systems maintain precise alignment across long drives in challenging ground, meeting strict centreline tolerance requirements.
Trenchless Execution
Pipe drives are completed without surface excavation, minimising disruption to traffic, businesses and the environment in Hong Kong's dense urban setting.
Settlement Risk Control
Ground investigation, real-time settlement monitoring and contingency planning systematically manage risks to neighbouring structures and utilities.
Mechanised Boring: The Key Choice for Urban Underground Works
Hong Kong's dense urban environment presents multiple challenges for underground works — constrained surface access, complex ground conditions and protection of adjacent assets. TBM's mechanised boring allows long-distance drives without surface disruption, making it the preferred approach for major government infrastructure contracts.
