Renovating historic structures presents unique challenges. Original building documentation is often lost, and structural deformations (settled columns, sagging floors, non-orthogonal walls) are common. Scan-to-BIM solves this by mapping actual structural conditions with millimeter accuracy.
The Process: Laser to Revit
Terrestrial laser scanners capture millions of coordinate points per second, outputting a detailed point cloud (.rcs/.rcp). Our BIM engineers index this data and construct a 3D Revit model directly over the point cloud, tracing walls, structural beams, and legacy service routes.
Why It Beats Manual Surveying
- Catches Deformations: Captures settled walls and sloped floors that traditional surveying misses.
- Reduces Safety Risks: Scans high, inaccessible zones safely from ground level.
- Zero-Clash Retrofitting: Allows new structural framing or modern HVAC runs to be coordinated with historic fabric virtually.
Partnering with Alliedge for Scan-to-BIM processing helps preserve historic facades while incorporating modern building services.
