Tunnel Engineer

Deliver structural design and analysis for tunnel and underground works (TBM Cut & Cover NATM) with strong capability to manage geotechnical inputs and groundstructure interaction assumptions. The role supports design development from concept to detailed/IFC under the guidance of the Lead Tunnel Engineer.

• 6 to 8 Years of experience
• Prepare structural design for underground structures including:
  • TBM tunnels (segmental lining design checks joints/gaskets assumptions ring build local openings cross-passages interfaces)
  • Cut & Cover tunnels (tunnel box roof/slab/walls construction staging effects temporary works design inputs)
  • NATM tunnels (primary and secondary lining concepts ground classes sequential excavation stages support measures coordination)
• Perform engineering calculations and analysis using appropriate methods (hand calcs software) including load combinations construction stages serviceability checks durability provisions and design reporting.
• Coordinate and interpret geotechnical deliverables and integrate them into structural design:
  • Review GIR/GDR borehole logs lab test results groundwater levels and derived parameters
  • Understand and apply soil/rock models and key parameters (γ φ c Su E ν K0 permeability rock mass classification)
  • Define and validate ground loads for tunnels: overburden surcharge lateral earth pressures groundwater pressures consolidation effects where applicable
  • Support assessments for settlement heave face stability basal stability and impact on adjacent utilities/structures (with geotechnical team)
  • Participate in defining instrumentation & monitoring requirements and trigger levels where required for design assumptions
• Support analysis and coordination for temporary works and construction methodology impacts (staged excavation dewatering assumptions support sequencing TBM construction load cases).
• Prepare and check drawings/design deliverables with BIM/CAD teams: typical sections reinforcement concepts waterproofing interfaces openings embedded items and cross-discipline interfaces (MEP/architecture).
• Contribute to technical inputs: design basis notes risk registers (geotechnical/design risks) RFI responses and coordination minutes.
• Provide construction support as needed: review method statements (design-related) respond to RFIs and support design changes/optimizations.

Qualifications :

• Bachelors degree in Civil / Structural Engineering (Masters preferred).
• 68 years relevant experience in tunnel/underground structural design with exposure to TBM Cut & Cover and/or NATM projects.
• Strong understanding of geotechnical engineering fundamentals relevant to underground structures including soil/rock behaviour groundwater effects and groundstructure interaction principles.
• Familiarity with international codes and practices used for underground structures (project-specific) and ability to produce clear calculation packages and design notes.
• Experience coordinating with geotechnical BIM MEP and alignment teams in a multi-disciplinary environment.

Additional Information :

Software

• Structural analysis/design tools such as PLAXIS 2D/3D and/or MIDAS GTS NX and/or RS2/RS3 (working knowledge expected; ability to interpret results and assumptions).
• General structural tools (as used in your team) such as SAP2000/ETABS/STAAD/Robot (as applicable).
• AutoCAD (drawing review/markups); Revit/Navisworks for coordination exposure preferred.
• MS Excel for calculation templates and data reduction; report writing in MS Word..
