HVAC BIM Modeling Services

HVAC BIM Modeling is the process of creating intelligent 3D models of mechanical systems—including ductwork, piping, equipment, and controls—that reflect real-world dimensions, manufacturer specs, and installation constraints. These models help contractors coordinate, prefabricate, and install with fewer field conflicts and faster turnaround.

We model all major HVAC systems used in commercial and industrial buildings:

• Supply, return, and exhaust ductwork
• Chilled water and hot water piping
• Steam and condensate systems
• Refrigerant lines
• Condensate drains
• Ventilation and makeup air systems
• VRF/VRV systems
• Rooftop units, AHUs, FCUs, VAVs, and split systems

We deliver models from LOD 300 to LOD 500, depending on project needs:

• LOD 300: Design-intent modeling for coordination
• LOD 350: Detailed routing with supports and clearances
• LOD 400: Fabrication-ready modeling with exact fittings and hangers
• LOD 500: As-built models based on field verification

Yes. We generate:

• Fabrication-ready duct and piping shop drawings
• Spool sheets for prefabrication
• Hanger layouts and embed plans
• Installation drawings for field crews

All drawings are extracted directly from the coordinated BIM model.

Absolutely. We accept:

• Revit (.RVT)
• AutoCAD (.DWG)
• Navisworks (.NWC/.NWD)
• PDFs, markups, and redlines
• Manufacturer content and submittals

We can also rebuild or clean up poorly structured models from other teams.

We run full clash detection using Navisworks and coordinate with plumbing, electrical, fire protection, and structural teams. You receive:

• Weekly clash reports
• Updated coordination models
• Issue tracking with screenshots and resolutions
• Final clash-free model ready for fabrication

Yes. Our LOD 400 HVAC models are built for prefabrication. We include:

• Exact duct and pipe lengths
• Fittings, valves, and accessories
• Hanger locations and embed points
• Spool breakdowns and labeling

This reduces field labor and speeds up installation.

Typical inputs include:

• Architectural and structural backgrounds
• HVAC design drawings and schematics
• Equipment schedules and submittals
• Manufacturer content
• BIM Execution Plan (if available)

We’ll help fill in any gaps to get started quickly.

Turnaround depends on project size, but most HVAC scopes are completed within 1–4 weeks. Fast-track schedules are available for contractors needing immediate support.

Yes. We support HVAC contractors nationwide on commercial, industrial, and institutional projects. All work is performed by U.S.-based engineers and modelers.

Our primary tools include:

• Autodesk Revit
• Autodesk Navisworks
• AutoCAD
• Fabrication CADmep (when required)

We follow industry-standard BIM workflows and contractor-friendly modeling practices.

Yes. We participate in weekly or biweekly BIM coordination meetings via Zoom, Teams, or your preferred platform. We also provide updated models and clash reports before each meeting.  Our P.E. will run the coordination meetings upon request if it is included in our scope of work up front.

Pricing is based on:

• Project size and complexity
• Required LOD
• Number of systems
• Coordination requirements
• Deliverables (shop drawings, spools, hangers, etc.)

We offer fixed-fee, hourly, and hybrid pricing depending on contractor preference.

Yes. As a licensed Professional Engineer (NY, NJ, ME), we can provide PE-stamped HVAC drawings when required for permitting or design-build projects.
