- Performing routine inspections, maintenance, and lubrication of TBM components such as cutters, hydraulics, and electrical systems.
- Ensuring accurate line and grade alignment using guidance systems during excavation.
- Coordination and supervision of precast segment erection and ring building.
- Monitoring and control of grouting operations behind the shield.
- Troubleshooting mechanical, hydraulic, electrical, and PLC-related issues during operations.
- Recording operational data, shift logs, and production reports.
- Compliance with safety protocols, risk assessments, and emergency procedures in confined spaces.
- Coordination with muck removal, ventilation, and probing/drilling teams.
- Review and reporting of instrumentation & monitoring (I&M) data for convergence and settlement.
- Assisting in TBM assembly, launch, breakthroughs, and disassembly as required.
