Scan to BIM
Leica RTC360 and Faro Focus laser scanning converted to accurate as-built Revit models. Full QA/QC with deviation analysis against the registered point cloud. Essential for renovation, retrofit, and healthcare projects where existing conditions are unknown.
Scan-to-BIM converts raw laser scan point cloud data into accurate, LOD-compliant Revit models that capture existing conditions with millimeter precision. Whether you are planning a renovation, validating as-built conditions against design intent, or creating a baseline for facilities management, our team delivers models built to your LOD specification, documented against survey data, and ready for immediate use in design and construction workflows.
Site Scanning
High-density scans are captured using Faro Focus or Leica RTC360 scanners at scan positions planned to ensure full coverage with minimal occlusion.
Point Cloud Registration
Individual scan positions are registered into a unified, georeferenced point cloud in Recap Pro, with residual error reports documenting accuracy.
BIM Modeling
Revit models are built directly against the point cloud to the specified LOD, capturing all visible elements including structure, architectural finishes, MEP, and equipment.
QA/QC Validation
Model elements are compared against the point cloud using deviation analysis tools, with variance reports showing accuracy within project tolerance bands.
Deliverable Package
We deliver the registered point cloud, Revit as-built model, deviation report, and a model usage guide covering file structure and LOD boundaries.
Do you provide the scanning equipment and crew, or do we hire a separate surveyor?
Our Scan-to-BIM service is end-to-end: we perform the laser scanning with Faro Focus or Leica RTC360 equipment, process the point clouds in Recap Pro, and deliver the Revit as-built models. If you already have a registered point cloud from a separate surveyor, we can also work directly from that data for modeling only — the scope adapts to what you already have.
What accuracy can we expect from the as-built Revit models?
Our scanning equipment captures at 3–6mm accuracy at standard scan ranges. Revit elements are modeled directly from the point cloud to within 3–10mm of actual field conditions. This compares to 50–100mm typical accuracy for tape-measure surveys. We provide deviation analysis reports documenting the variance between the model and point cloud for every delivered model.
What LOD are the Revit models delivered at?
Standard Scan-to-BIM deliverables are LOD 300: structural framing, architectural shell, mechanical equipment, and visible MEP systems modeled with accurate dimensions and spatial coordinates. LOD 350 or 400 is available for specific systems where greater detail is required. We agree on LOD requirements per system in the project brief before scanning begins.
How long does scanning a building take?
A 50,000 SF floor plate typically takes 1–2 days to scan completely with full coverage. A 200,000 SF building typically requires 3–5 days on-site. Modeling from the point cloud typically takes 2–4 weeks per 50,000 SF depending on LOD and discipline scope. We provide a project-specific timeline at proposal stage.
What file formats are included in the deliverable package?
Standard deliverables include: the registered point cloud (.rcp for Revit linking, .e57 for archival), the Revit as-built model (.rvt), floor plans, sections, and elevations extracted in PDF and DWG, and a QA/QC deviation report. All files are organized with a model usage guide covering file structure and LOD boundaries.
