- Ensure all tunneling activities comply with project specifications, drawings, codes (IS, BS, ACI, EN), and client/consultant requirements.
- Maintain up-to-date revision control for all quality documents.

2. TBM Tunnel Construction Quality Control

(Applicable for shield/EPB/TBM tunneling projects)

- Inspect and verify:
- TBM assembly & daily pre?launch checks
- Cutterhead tools, disc cutters, scrapers, brushes
- Main drive torque, pressure levels, and system parameters
- Slurry/EPB conditioning materials and their dosing
- TBM advance sequence, thrust forces, and ring build parameters

- Monitor segment installation, grout injection, and annular gap filling quality.
- Ensure correct segment type, orientation, gasket condition, and bolt torquing.
- Check for segment damage, joint opening, spalling, honeycombing, or misalignment.

3. Precast Segment Quality Control

- Inspect segment delivery, handling, and storage at the tunnel portal/launching shaft.
- Check segment dimensions, surface finish, gasket alignment, lifting points, and embedded items.
- Verify segment traceability (batch number, production date, ring ID).

(If you want,



I can also share detailed segment?specific QC checklists.)

4. Material Testing & Verification

- Conduct/monitor routine testing:
- Concrete slump & compressive strength
- Shotcrete rebound, thickness, core tests
- Grout pressure, density, viscosity
- Rock bolt pull-out tests

- Ensure all materials have valid MTCs, approvals, and compliance certificates.

5. Tunnel Survey & Alignment Quality

- Verify excavation profiles using total station/laser scanning.
- Check TBM guidance system readings and ring alignment.
- Confirm tunnel geometry within tolerance (convergence, clearance, grade, alignment).

6. Non-Conformance & Corrective Actions (NCR/CAR)

- Identify, report, and record any Non-Conformance Reports (NCRs).
- Coordinate with construction teams to implement corrective actions.
- Verify rectification works and close NCRs with proper documentation.

- Daily QA/QC reports
- Checklists and inspection reports
- Test reports
- Tunnel segment installation records
- Grouting logs & as-built documentation

- Maintain systematic filing for audits and client verification.

8. Safety & Compliance

- Ensure compliance with tunnel safety standards (confined space, ventilation, gas detection).
- Verify certification of lifting equipment used for precast segments.
- Support HSE team in incident investigation involving quality issues.
