BIM Coordinator | Fire Protection Engineering

I coordinate MEP models with the engineering behind them, resolving clashes with the sprinkler coverage rules, hydraulics and installation limits in mind. Currently Design Manager / BIM Coordinator – Fire Protection at Tong Loong Engineering, Singapore.

How I work

BIM coordination first, with engineering depth behind every decision

Coordination is the core of the role. Fire protection engineering makes each coordination decision technically sound, so a rerouted pipe still passes design review.

Core

BIM coordination

  • Revit MEP modelling to project standards, project setup and families
  • Model federation and clash detection in Navisworks Manage
  • Clashes classified; major issues escalated as RFIs and re-tested
  • Issues tracked in Revizto; models shared via ACC / BIM 360

Core

Information management

  • ISO 19650-2 delivery at task-team level
  • CDE workflow in ACC: WIP → Shared (S1) → Published
  • TIDP, DRM review, BEP naming conventions
  • Model QA against BEP rules before every Shared submission; COBie / asset data

Specialist edge

Fire protection engineering

  • Sprinkler, ESFR, in-rack, pre-action, deluge, foam and water curtain systems
  • Hydraulic calculations in FHC when routes or pipe sizes change
  • Code-aware rerouting: coverage, spacing and obstruction checked first
  • SCDF Fire Code, SS CP 52, NFPA 13 · BEng and MSc Mechanical Engineering

Digital automation

Repetitive BIM tasks turned into repeatable Dynamo workflows

Dynamo graphs with Python and the Revit API, run from Dynamo Player, producing checkable outputs: Excel reports, flags, colour overrides or placed elements.

Clash flags placed automatically in Revit at Navisworks clash points on ductwork and pipework
Navisworks clash XML → Dynamo → flags placed in Revit, assigned by trade
  • BIM Model Health Checker8 h → 10 min
  • BEP Compliance Checker3 h → 7 min
  • Clash Flag Placement1 h → 3 min
  • Pipe Sleeve & Wall Opening2 h → 6 min
  • Pipe Hanger Placement2 h → 6 min
  • Pipe & Duct System Creation3 h → 5 min

Plus Missing Parameter Checker, Fire Hydrant Spacing Checker and Pipe & Duct Split by Length. Time savings are estimates, not measured productivity data.

Coordination workflow

Run as a controlled process, with evidence kept in the CDE

  1. Design requirementsCodes, BEP, naming and client requirements reviewed
  2. Model developmentRevit FP / MEP modelling to project standards
  3. FederationDiscipline models federated in Navisworks
  4. Clash detectionSearch sets, clash rules and tolerances
  5. CoordinationResolutions agreed with architecture, structure and MEP
  6. RFI resolutionMajor issues raised as RFIs; replies checked
  7. QAQA checklist, model health and parameter checks
  8. Information exchangeShared via the CDE; submitted for authorisation

When does a clash become an RFI? When it has a time or cost impact, or affects structure, authority approval, safety or code compliance. Minor clashes are closed in coordination meetings.
