For VDC Leads
Point Cloud Data You Can Actually Build From
VDC workflows are only as good as the data they’re built on. When the existing conditions scan is incomplete, out of tolerance, or unregistered to the design model, the downstream coordination work carries that error forward — into fabrication, into clash detection, into the construction schedule.
OnSite3D provides engineering-grade point cloud data registered to your design model, deviation reports that identify real constructability issues before they reach the field, and VDC coordination that’s oriented toward fabrication outcomes — not just cleaner models.
Garbage In, Garbage Out — And in Brownfield Work, the Input Is Often the Problem
Most brownfield VDC coordination failures trace back to the same issue: the existing conditions data wasn’t good enough. Scans with gaps. Point clouds not registered to the design coordinate system. Survey data that doesn’t capture the actual tie-in configuration at the level of detail fabrication requires.
The VDC team builds a coordination model on that data, catches some clashes, misses others — and the ones that matter show up at installation.
OnSite3D’s scan workflow is designed around what VDC coordination actually needs: complete coverage, engineering-grade accuracy, registered to the design model, with deviation reporting that flags real issues before fabrication begins.
Scan Data Built for Coordination, Not Just Visualization
Engineering-Grade Point Cloud Capture
We scan with high-accuracy LiDAR systems designed for industrial facility documentation. Coverage is complete — including congested pipe racks, restricted-access areas, and the specific tie-in geometries that drive fabrication. Point clouds are registered to your design coordinate system and hosted on WebShare from Day 1.
Scan-to-Model Registration & Deviation Reporting
Our VDC team registers the point cloud against the design model and produces deviation reports that identify where existing conditions diverge from design assumptions. Clashes and constructability issues are flagged before fabrication — at desk cost, not field cost.
Constructability-Driven Coordination
OnSite3D’s VDC workflows are oriented toward field installation outcomes. We’re not just making the model look clean — we’re making sure the fabrication package that comes out of the coordination process will install in the actual facility. Every handoff is designed to reduce friction at the next step.
Third-Party Scan Data Ingestion
If you have existing point cloud data from another source, OnSite3D can ingest it (tolerance-verified) and integrate it into our coordination and fabrication workflow. The addressable scope for Scan-to-Fab and Virtual Assemblies extends beyond facilities we’ve scanned ourselves.

Third-Party Data Ingestion
Existing point cloud data (tolerance-verified) integrated into OnSite3D coordination and fabrication workflow.
Coordination That Closes the Loop to Fabrication
Scan Quality That Supports Fabrication
OnSite3D’s point clouds are captured and registered to the tolerances fabrication requires — not just visualization tolerances. When the scan drives the spool dimensions, the data needs to be right at the millimeter level. Ours is.
Deviation Reporting That's Actionable
We don’t just flag that a clash exists — we identify what it means for the fabrication package, what the constructability implication is, and what needs to be resolved before steel is cut. The coordination output is designed to drive decisions, not just document problems.
Integrated Fabrication Capability
OnSite3D can take the coordination output and fabricate from it — ABSA AQP certified, laser QA’d, first-time fit-up by design. For VDC teams looking for a coordination partner who closes the loop to physical deliverables, that’s a different kind of relationship than a pure coordination consultant.
One Workflow from Scan to Installed
Scan, registration, coordination, simulation, engineering, and fabrication are one integrated process at OnSite3D. No data handoffs between vendors that introduce translation errors. The model that drives coordination is the same model that drives fabrication.
Tell Us What You're Coordinating
Send us the scope, the existing conditions challenge, and what the fabrication package needs to look like. We’ll come back within 48 hours with a planning estimate — what we’d scan, how we’d coordinate it, and what we’d fabricate.
No commitment. No generic proposal. A real answer for your VDC scope.
