work process flow

Laser Scanner → Point Cloud: High-precision laser scanners (e.g., Leica, FARO) capture millions of data points from site conditions, creating a dense 3D point cloud that documents exact geometry with millimeter accuracy.

Point Cloud → Registration: Raw scans are stitched together using software like Autodesk ReCap or Leica Cyclone, cleaned of noise (e.g., people, furniture), and registered into a unified file (RCP/RCS/E57 format) ready for BIM import.

Registration → Revit Model: Import the point cloud into Revit, align coordinates/levels/grids, then model MEP elements (ducts, pipes, trays, equipment) by tracing against the cloud—starting with structure/architecture for reference.

Revit Model → QA/QC: Validate model accuracy via deviation measurements, section cuts, clash detection (Navisworks), and rule checks; document tolerances (3-5mm typical) and issue as-built sheets/IFC exports.
