Tunnel BIM/CAD

Role Overview

Support delivery of BIM and CAD outputs for tunnel projects (TBM, Cut & Cover, NATM) by developing coordinated models and drawings, maintaining model quality, and supporting interdisciplinary coordination under the direction of BIM Lead and Tunnel Design Leads.

Key Responsibilities

• Develop and update Revit BIM models for tunnel works (TBM lining/segments, C&C tunnel box, NATM primary/secondary lining) and associated components (cross passages, shafts, portals, niches, plant rooms where applicable).
• Produce and maintain 2D drawings from models: GA plans/sections, typical details, reinforcement/embedded items coordination drawings (as applicable), and interface drawings.
• Perform model coordination with civils/structures, MEP, architectural, and alignment teams; support clash detection and resolution in coordination meetings.
• Ensure model/drawing quality: adherence to BIM standards, naming conventions, worksets, view templates, sheet setup, and consistent annotations.
• Support extraction of quantities/schedules where required (basic take-offs from model) and maintain revision control.
• Manage model exchanges and submissions via ACC/CDE, including packaging, model publishing, and responding to review comments.

Qualifications & Experience

• Diploma/Bachelor’s in Civil/Structural/Mechanical/Architectural Engineering or equivalent.
• 6–8 years’ experience in BIM/CAD for infrastructure, with strong exposure to tunnels/underground works (TBM, C&C, NATM preferred).
• Good understanding of tunnel deliverables and coordination needs (alignments, profiles, sections, interfaces, tolerances, constructability).
• Ability to work with multiple stakeholders and deliver under schedule with good attention to detail.

Software

• Revit, Navisworks, AutoCAD, ACC/ProjectWise.
