HVAC BIM Services

Coordinated 3D HVAC Revit Models, From Ductwork to Equipment, Built to Your Required LOD

Modeling HVAC systems in Revit, covering ductwork, equipment, piping, and mechanical rooms, so the model reflects what actually gets installed. Every model is built to the LOD your project needs, keeping it coordination-ready for other trades and fabrication-ready for shop drawings. Our dedicated MEP BIM team of direct employees only handles deliverables under an ISO-certified delivery process.

Why Gsource

Why Outsourcing HVAC BIM Modeling Services to Gsource

A Dedicated MEP BIM Team, 50+ Specialists

Your model runs on a dedicated bench producing 1,000+ Revit models monthly, not a shared queue. Scale up or down without hiring modelers.

Modeled to Your LOD and Revit Standards

We adopt your Revit templates, shared parameters, families, view templates, and BIM Execution Plan from day one, and model to the exact LOD your project requires (LOD 100 to 500).

Coordination-Ready and Fabrication-Ready

Models built to federate cleanly, survive clash detection, and carry through to shop and spool drawings.

Direct Employees Only, No Subcontractors

Every MEP BIM modeler is a direct Gsource employee, so your models and project data stay within one accountable, ISO 27001-certified organization.

Dedicated Account Manager

A named account manager and project lead, not a shared queue or ticketing system, with coverage aligned to your time zone.

Our Process

HVAC BIM Services Workflow

1

Standards & BEP Onboarding

We align on your BIM Execution Plan, adopt your Revit templates and families, confirm target LOD, sign NDA, and collect all source inputs before modeling begins.

2

Template Setup and Model Validation

We configure the project template and validate the base model against your standards to confirm if the foundation is correct before HVAC modeling starts.

3

HVAC BIM Modeling to the Agreed LOD

We model ductwork, equipment, and piping to the LOD confirmed at onboarding, keeping the model coordination-ready for other trades.

4

QA and Model Review

Every model passes an internal quality check under our ISO 9001-aligned process before it moves to delivery.

5

Delivery & Handoff

We deliver the model in RVT, NWC, and IFC formats along with a file index and change log for a clean handoff.

Our Tools

Built for Your System

No tool retraining. We adapt to your standards. We onboard to your CAD/Revit templates and standards in week one.
