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.

Numbers our clients hold us to, measured across every drawing and model we deliver.
On-time delivery
Drawing sets delivered on the schedule agreed at project kickoff, so your permit submissions and downstream project timelines stay on track.
Drawing accuracy
Verified against internal QC checklists and applicable code requirements before a set ever reaches your desk.
First-time client approval
Drawing sets approved by architecture firms on the first review round, with minimal revision cycles needed.
Revision request rate
Requests for rework after delivery, a reflection of the accuracy built into the drafting process from the start.
Client identities protected under NDA. Project details verified.
Project Type: Institutional Library Building

Your model runs on a dedicated bench producing 1,000+ Revit models monthly, not a shared queue. Scale up or down without hiring modelers.
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).
Models built to federate cleanly, survive clash detection, and carry through to shop and spool drawings.
Every MEP BIM modeler is a direct Gsource employee, so your models and project data stay within one accountable, ISO 27001-certified organization.
A named account manager and project lead, not a shared queue or ticketing system, with coverage aligned to your time zone.
Clearly defined deliverables and fixed-scope milestones.
Ongoing technical support and on-demand expertise.
High-volume, multi-disciplinary, long-term integration.
Adaptive workflows & complex, evolving project requirements.
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.
We configure the project template and validate the base model against your standards to confirm if the foundation is correct before HVAC modeling starts.
We model ductwork, equipment, and piping to the LOD confirmed at onboarding, keeping the model coordination-ready for other trades.
Every model passes an internal quality check under our ISO 9001-aligned process before it moves to delivery.
We deliver the model in RVT, NWC, and IFC formats along with a file index and change log for a clean handoff.
No tool retraining. We adapt to your standards. We onboard to your CAD/Revit templates and standards in week one.
Tell us about your project. We’ll scope your HVAC systems, required LOD, and Revit standards, then share relevant project examples to show how we can work as an extension of your team.
