Job Description

Company Description
Great Platform for Talent

Deliver structural design and analysis for tunnel and underground works (TBM, Cut & Cover, NATM), with strong capability to manage geotechnical inputs and ground-structure 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 (?, ?, c, Su, E, ?, 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

• Bachelor's degree in Civil / Structural Engineering (Master's preferred).
• 6-8 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 ground-structure 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..
