Key Responsibilities
TBM Operations Monitoring — Face Pressure, Advance Parameters & Machine Data
- Monitor TBM tunnelling operations and ensure that excavation activities are carried out in accordance with the approved drive instruction sheet, method statements, ITPs, and TBM protocol aligned with contract specifications — maintaining constant technical oversight of the TBM advance process to verify that the machine is operated within the parameters established by the geotechnical and structural design to protect adjacent structures, utilities, and ground stability during excavation
- Review drive instruction sheets and monitor implementation of assigned TBM parameters — tracking and verifying face pressure settings, machine advance rate, applied torque and thrust force, cutterhead RPM, screw conveyor settings, muck parameters, and all other critical machine data against approved drive parameters, identifying any deviations and ensuring prompt corrective action before they affect tunnel stability or surface settlement
- Identify abnormal conditions and potential risks during TBM advance relative to applied face pressure and the current machine location in relation to adjacent buildings, roads, utilities, and other critical assets — applying experienced engineering judgment to recognize the early warning indicators of face instability, excessive ground loss, or unexpected ground condition changes that require immediate response from the TBM operating team and engineering supervision
- Identify and report abnormal TBM parameters, excessive ground settlement, unexpected ground conditions, water ingress, loss of face pressure, excessive grout pressure, or other conditions affecting tunnel stability — maintaining the proactive monitoring and rapid escalation practices that protect both the TBM operation and the integrity of the urban infrastructure above and adjacent to the tunnel drive
Segment Inspection, Ring Installation & Tunnel Lining Quality
- Inspect and monitor TBM ring installation in accordance with approved ITPs and segment repair method statements — verifying gasket condition before segment placement, confirming correct segment identification and positioning within each ring, checking ring build-up lip and step tolerances, verifying joint alignment, and immediately identifying and documenting any segment damage that may compromise the structural integrity or watertightness of the completed tunnel lining
- Inspect bored tunnel segment condition and identify defects — systematically cataloguing cracks, damaged edges, isolated moisture damp patches, sources of leakage, and other structural or watertightness anomalies in installed precast concrete segments, classifying each defect in accordance with contract requirements, and tracking the implementation and completion of approved repair methods for all identified defects
- Verify annular gap/backfill grouting operations including grout pressure, grout volume, grout mix, injection sequence, and continuity of grouting behind tunnel segments — ensuring that the annular void between the TBM tail skin and the installed segment ring is fully and continuously filled with grout at the correct pressure and with the specified grout mix, preventing ground settlement, ring float, and void formation that could compromise tunnel structural performance
Geotechnical Coordination, I&M Monitoring & Ground Risk Management
- Coordinate with Instrumentation and Monitoring (I&M) teams for closer monitoring to ensure that settlement occurring during TBM operations remains within allowable design limits — particularly in critical zones such as main roads, existing buildings, public utilities, structures, and waterways where surface settlement must be managed within tight tolerance bands to protect public safety and operational continuity
- Report and notify Geotechnical teams to assess abnormal ground behavior due to unexpected changes in ground conditions which may lead to discrepancy with the approved design — maintaining close communication with the geotechnical supervision team to ensure that any ground condition information revealed during TBM advance is promptly assessed against design assumptions and that the drive instruction sheet parameters are updated accordingly
- Monitor preparation of planned and unplanned interventions including geological face mapping — reviewing ground conditions encountered at intervention locations and comparing with approved design conditions and recommendations for the TBM’s current position, including rock quality, fractures and joints, groundwater levels, weak zones, cavities, and other adverse conditions that may require design review or construction method modification
- Inspect tunnel drainage systems — both temporary and permanent — to ensure safe and smooth TBM operation and that groundwater control measures are functioning correctly throughout the TBM drive
TBM Maintenance, Shift Coordination & Technical Documentation
- Supervise and follow up regular TBM-related activities including tail seal grease application, regular machine maintenance, grout supply, segment handling, and foam consumption within the TBM — ensuring that all routine TBM maintenance activities are carried out consistently and on schedule to maintain steady, safe, and productive TBM operation throughout the tunnel drive
- Coordinate with the TBM shift contractor team to implement and review shift and daily reports, TBM data including excavation records, ring installation records, and grouting records — ensuring that all TBM operational data is accurately captured, completely documented, and properly maintained in accordance with the project’s quality and record management requirements
- Coordinate and supervise contractor team during TBM assembly, disassembly, and transport from ports to site or between sites — including road survey to define accessible transport routes, verifying that all lifting, transport, and installation activities are performed safely and in accordance with the TBM manufacturer’s and project’s approved procedures
- Ensure that construction records and as-built information are complete, accurate, traceable, and properly maintained — maintaining the documentation discipline that provides the legal, technical, and contractual record of the tunnel construction that the project client, design team, and future asset managers will rely on throughout the tunnel’s operational life
QA/QC, HSE Compliance & Stakeholder Coordination
- Ensure that tunnel construction activities are performed in accordance with approved HSE, Management, and QA/QC plans — maintaining personal commitment to safety leadership and quality compliance in the TBM tunnel working environment, and supporting the Resident Engineer in ensuring that the contractor team consistently applies the project’s safety and quality management systems throughout all tunnel construction activities
- Review method statements, material submittals, technical proposals, test plans, and other technical documents related to tunnel construction — providing technically grounded comments and recommendations to the Resident Engineer that verify the contractor’s proposed working methods are compliant with contract requirements and appropriate to the specific ground conditions and construction challenges of the Dubai tunnel project
- Monitor tunnel construction progress against the approved baseline program and construction sequence — highlighting any predicted delays, identifying their causes, and supporting the development of recovery measures that allow the tunnel drive to return to the approved program without compromising quality or safety
Qualifications & Requirements
Educational Requirements
- Bachelor’s Degree in Civil Engineering or a related engineering field from an accredited institution — the engineering foundation that underpins TBM tunnelling system understanding, geotechnical awareness, structural knowledge, and QA/QC competence
