The Senior HVAC BIM Modeller is responsible for developing, managing, and coordinating detailed 3D BIM models for HVAC systems in construction projects. This role involves working closely with engineers, architects, and other disciplines to ensure accurate design integration, clash-free models, and compliance with project standards.
Key Responsibilities
BIM Modelling & Development
Develop LOD 200–500 HVAC BIM models using Autodesk Revit (MEP)
Model HVAC systems including:
Air distribution systems (ducts, fittings, dampers, VAVs)
Hydronic piping (CHW, condenser water, refrigerant piping)
HVAC equipment (AHU, FCU, VRF, chillers, pumps, etc.)
Create parametric families for HVAC components where required
Ensure models are aligned with design intent, calculations, and specifications

Coordination & Clash Detection
Perform clash detection using Navisworks Manage/Simulate
Coordinate HVAC systems with:
Architectural elements (ceilings, shafts, walls)
Structural components (beams, slabs, columns)
Other MEP services (electrical, plumbing, fire protection)




Lead and participate in BIM coordination meetings
Propose and implement practical routing solutions to resolve clashes

Shop Drawings & Documentation
Prepare detailed shop drawings and installation drawings from BIM models
Generate:
Duct layouts and sections
Piping layouts and isometrics
Equipment schedules and BOQs
Ensure drawings comply with standards such as ASHRAE and SMACNA
Maintain drawing registers and revision control

BIM Standards & Quality Control
Ensure adherence to project-specific BIM Execution Plans (BEP)
Follow company BIM standards, naming conventions, and workflows
Conduct QA/QC checks on models and drawings
Audit models created by junior modellers for accuracy and completeness

Project Coordination & Communication
Liaise with HVAC design engineers to understand system requirements
Coordinate with site teams for constructability and installation feasi
