CONSTRUCTION MANAGER

1. Construction Planning and Project Execution Develop construction methods, work sequences, and execution strategies in accordance with approved drawings and specifications. Prepare construction schedules, resource plans, manpower deployment, and equipment requirements.

Coordinate daily, weekly, and monthly construction activities. Monitor progress against project milestones and implement recovery plans for delays. Ensure construction activities comply with contractual requirements, approved method statements, and inspection and test plans (ITPs). 2.

Tunnel Boring Machine (TBM) Operations Oversee TBM excavation activities, including EPB, slurry, or hard-rock TBM operations, as applicable. Coordinate TBM launch, tunneling advance, breakthrough, and retrieval activities.

Monitor TBM performance indicators, including advance rate, penetration rate, thrust force, torque, cutterhead pressure, and stoppages. Ensure proper coordination of segment erection, tail-void grouting, muck removal, and tunnel logistics.

Monitor ground conditions, face pressure, settlement, groundwater inflow, and potential risks during excavation. Coordinate TBM maintenance, cutter changes, consumables, and critical spare parts with the TBM team. 3.

NATM/SEM and Conventional Tunneling Supervise excavation sequences, including top heading, bench, and invert construction, where applicable. Ensure timely installation of initial support, such as shotcrete, rock bolts, steel ribs, lattice girders, and wire mesh.

Review geological conditions, rock mass classifications, and tunnel face mapping with the engineering and geotechnical teams. Ensure excavation rounds, support installation, and monitoring comply with the approved excavation and support design.

Coordinate probe drilling, pre-grouting, dewatering, and water-ingress control measures where required. 4. Tunnel Lining and Civil Works Manage precast segment installation and quality control for TBM-driven tunnels. Supervise secondary lining, waterproo
