Laser Scanning & Mechanical Coordination for HVAC Contractors
HVAC and mechanical contractors operate on tight margins. Field conflicts, coordination failures, and rework are the fastest way to lose profit on a project. OAR provides 3D Laser Scanning and BIM Coordination & Virtual Construction services that give your team verified existing conditions, clash-free models, and fabrication-ready data before your crew ever touches ductwork.
Based in Portsmouth, New Hampshire, OAR serves HVAC and mechanical contractors across the Northeast: Massachusetts, Maine, Vermont, New York, Connecticut, and Rhode Island. BIM Coordination & Virtual Construction is delivered remotely nationwide.
Every system fits in the model before your crew picks up a wrench
Ductwork That Fits the First Time
Your Installers Work from Resolved Information
Coordination Bandwidth Without the Overhead
Accurate Quotes, Protected Margins
Most mechanical coordination failures trace back to inaccurate existing conditions.
Outdated drawings, missing clearance data, and field-measured assumptions create conflicts that don’t surface until installation. At that point, fixing them costs three to five times more than preventing them.
HVAC contractors working in occupied commercial buildings, industrial retrofits, and complex mechanical rooms face this challenge on every project. The tolerance for field error is zero when ductwork and piping are being prefabricated offsite.
The fix is not more field time. It is verified data before fabrication starts.
Three services. One partner.
3D Laser Scanning for Existing Conditions
Millimeter accuracy. No guesswork.
OAR captures existing mechanical rooms, ceiling plenum spaces, structural elements, and equipment clearances with millimeter-level accuracy. The resulting point cloud replaces manual field measurements and gives your team verified geometry for coordination and fabrication.
Scan to BIM for Mechanical Systems
Point cloud to fabrication-ready model.
We convert point cloud data into Revit-based coordination models that reflect actual field conditions. These models feed directly into your mechanical and sheet metal coordination workflows, clash detection, and fabrication drawing production.
Mechanical & Sheet Metal Coordination
Conflicts resolved before they reach the field.
OAR’s BIM Coordination & Virtual Construction services manage clash detection, constructability review, and trade coordination for mechanical and sheet metal systems. We work alongside your project team to resolve conflicts before they reach the field.
Project types we support.
OAR partners with HVAC and mechanical contractors across a range of project types. If your work involves prefabrication, complex existing conditions, or BIM coordination requirements, we can help.
Mechanical coordination for commercial build-outs and tenant improvement projects with complex existing conditions and tight ceiling plenums.
Existing conditions capture and coordination for industrial facility retrofits where documentation is missing, outdated, or unreliable.
Scan-accurate Revit models that give fabricators verified field geometry before a single piece is cut. Assemblies fit because the data was verified first.
Strict clearance requirements, infection control zones, and complex MEP systems in occupied facilities. We work around your operational constraints.
Mechanical coordination as part of OAR’s broader BIM Coordination & Virtual Construction scope. One partner from scan to coordinated model delivery.
Five deliverables. One accountable partner.
3D Laser Scanning that captures what is actually in the field, not what the drawings say should be there. Point clouds in .RCP, .RCS, or .E57 format, ready for your coordination workflow.
3D models built from point cloud data and aligned to actual field geometry. LOD 200-350 depending on your project requirements. Ready for clash detection and fabrication.
Every conflict identified and resolved in the model before a single piece of ductwork or piping is fabricated or ordered. Hard clashes, soft clashes, and clearance violations all flagged and tracked.
Shop drawings based on scanned field conditions so prefabricated assemblies fit during installation. Produced from verified Revit models, not design intent drawings.
OAR owns the full chain from site scan to coordinated model. No handoff gaps between the scanning team and the BIM team. One partner responsible for the outcome.

Frequently asked questions
HVAC contractors working on commercial, healthcare, or industrial projects are increasingly required to participate in BIM coordination and submit coordinated Revit models as part of contract requirements. OAR provides Scan to BIM and mechanical coordination services so HVAC contractors can meet these requirements without building an in-house VDC team.
OAR’s laser scanning captures existing conditions at millimeter-level accuracy, well within the tolerances required for mechanical coordination and prefabrication. Point cloud data reflects actual field geometry, not design intent, which is critical for mechanical systems in occupied buildings or complex retrofit projects.
OAR converts point cloud data into Revit coordination models and can support fabrication drawing production for mechanical and sheet metal systems. Scan-based models ensure dimensions reflect actual field conditions, reducing the risk of prefabricated assemblies that don’t fit during installation.
OAR supports HVAC contractors on commercial tenant improvements, healthcare facilities, industrial retrofits, data centers, and design-build projects. We handle field scanning across the Northeast and take coordination scope work nationwide.
Most commercial mechanical rooms and ceiling plenum areas are captured in one to two days. OAR coordinates access requirements with your project team to minimize disruption to occupied facilities.
