Scope Of Work

Segmental tunnel lining ring modelling — TBM bored circular cross-section with full ring geometry
Dual-track system BIM: rails, sleepers/concrete bearers, ballast or floating slab track elements
Rail fastening component modelling (teal-coded fastening assemblies per actual track specification)
Cable management systems: overhead cable ladder trays along tunnel crown and upper sidewalls
Individual cable bracket and conduit support arrays along tunnel sidewalls (full-length routing)
4D BIM construction sequence blueprint with a laptop.
Architectural blueprints with pencil, ruler, and eraser. As-built documentation.
Tunnel lighting BIM elements modelled at actual spacing and mounting positions
Railway M&E systems integration: third-rail/power rail supports, signalling equipment brackets
Tunnel cross-passage interfaces — opening coordination with cross-passage structure
Clash detection between track slab, cable management, civil lining, and M&E components
Longitudinal sections and cross-section documentation views for construction reference

Key Deliverables

Full tunnel BIM model (Revit) — segmental lining, track, cable management, and M&E combined
Cross-section BIM views at regular intervals for construction and inspection reference
Longitudinal section BIM views showing services routing along tunnel bore
Track system BIM model with rail fastening components and sleeper spacing
Cable management BIM model — ladder trays, brackets, conduit supports with quantities
Clash detection report (Navisworks) — civil vs. track vs. M&E resolved issue log
As-coordinated model handover for contractor site use
BIM quantity take-off data for cable brackets and track components

Why This Matters

Precision Modelling

Each segment ring, rail fastening, and cable bracket modelled to exact geometry — reducing on-site measurement errors.

Full Tunnel Length

Continuous BIM model spanning the full tunnel bore — not just spot sections — enabling consistent construction documentation.
Construction blueprint with hard hat, tape measure, level, and keys. 6D BIM Operation & Maintenance model.
Architect reviewing 4D BIM construction sequencing model blueprint with magnifier and ruler, focusing on building details.

Multi-System Coordination

Track, civil lining, and M&E services coordinated in one model — eliminating conflicting installation sequences on site.

LTA BIM Compliant

Delivered to LTA BIM standards and BCA BIM Roadmap requirements for MRT rail infrastructure projects.
