What You'll Be Doing:
- Assist the Resident Engineer in supervising tunnel/galleries construction activities with its connection to main tunnel including NATM and temporary works for station interfaces, shafts, and associated underground works.
- Monitor and supervise activities for galleries excavation by NATM in accordance with approved drawings, specifications, design requirements, method statements, excavation sequences, and temporary support arrangements.
- Monitor NATM excavation cycles, including excavation, scaling, rock support, shotcrete application, rock bolts, lattice girders, steel ribs, wire mesh, fore poling/spiles, drainage, waterproofing, and invert construction verifying that all activities is carried out in accordance with the approved excavation class, support class, geological conditions, and observational method requirements.
- Coordinate with the Geotechnical and Engineering teams to assess actual ground conditions and ensure that appropriate temporary/permanent support measures are implemented where required.
- Monitor geological face mapping and review ground conditions encountered during NATM excavation to be aligned with approved design assumption and condition, including rock quality, fractures joints, groundwater levels, weak zones, cavities, and other adverse conditions.
- Monitor tunnel convergence, settlement, deformation, crown movement, face stability, and other instrumentation and monitoring parameters during NATM activities.
- Coordinate with the Instrumentation & Monitoring (I&M) team to ensure monitoring data is reviewed against approved trigger, alert, and action levels.
- Monitor shotcrete application, including surface preparation, thickness, reinforcement/fibre requirements, design mix requirements, rebound control, curing, and testing.
- Monitor installation of temporary support systems in accordance with approved designs and sequence.
- Inspect and verify excavation profiles, overcut/undercut, tunnel/gallery alignment, chainage, level, and excavation dimensions in coordination with the Survey Team.
- Monitor gallery excavation, including setting out, pilot excavation, enlargement, scaling, temporary support, shotcrete, steel ribs, waterproofing, reinforcement, and permanent concrete lining.
- Coordinate gallery excavation activities in parallel with advanced TBM to ensure safe interface between teams to avoid conflicts with tunnel operations.
- Monitor ground conditions and water ingress during gallery excavation and ensure appropriate temporary support and dewatering measures are implemented.
