Tunnel Construction Manager - Civil

1) Planning & Controls

aDevelop look-ahead (1/2/4-week) plans, ring/shift targets, resource leveling, and constraint removal.

bSequence activities across launching/retrieval shafts, TBM drives, cross-passages, and post-tunnel works.

cChair daily DPR and weekly progress reviews; track earned value (planned vs actual rings, shaft milestones).

2) TBM Civil Execution

aOversee segment logistics (yard → shaft → tunnel buffer → erector); minimize damage and handling risks.

bEnsure ring-build excellence: correct segment type/taper, gasket integrity, dowels/bolts, torque, offsets & steps within ITP tolerances.

cControl annulus grouting

dCoordinate alignment corrections with Survey

eManage interface civil tasks: starter/stopping blocks, cradle beams, thrust frame supports, muck bay slabs, sealing at reception.

3) Shafts & Surface Works

aPlan cross-passage enabling works (breakout segments, pre-support, waterproofing interfaces), and post-tunnel finishing.

4) Safety, Health & Environment (SHE)

aEnforce confined space and pressurized system safety; align with LOTO around rotating equipment and high-pressure grout lines.

bDrive zero-harm culture: permits-to-work, lifting plans, emergency egress, housekeeping, spill response.

cLead incident investigations; implement corrective/preventive actions

5) Quality Assurance / Compliance

aEnsure adherence to ITPs, Method Statements, RA, and design drawings; manage NCR closure.

bApprove batching/grouting records, ring build checklists, segment repair logs, post-grout leak rectification.

cOwn as-built integrity; offsets/steps, grout volumes, settlement observations integrated with geotechnical inputs.

6) Interface Management

aCoordinate closely with TBM Pilot, Survey Lead, Mechanical/Electrical, Slurry treatment plant Engineer, and Logistics/Stores for uninterrupted advance.

bcoordinate with Client/PMC, OEMs (TBM manufacturer, guidance system), and third-party utilities for approvals 

7) Resourcing & Leadership

aBuild and lead civil team

bDrive competence: onboarding, SOP training (ring build/grouting/lifting), skill matrix, and shift coverage.

cOptimize manpower and plant utilization; prepare requisitions for segments, grout consumables, epoxy kits, and spares.

8) Risk & Change Management

aIdentify and mitigate risks: geological changes, water ingress, settlement sensitivities, segment supply constraints.

bManage design changes/variations, claim documentation, and commercial impacts (productivity losses, disruptions).
