Heritage Building 3D LiDAR BIM Model

I have a heritage shop-lot that must be captured and translated into an accurate Building Information Model. The goal is a single, clash-free BIM that reflects the structure, interior finishes and the complete mechanical layout, suitable for conservation engineering and refurbishment planning.

Scope
• On-site data capture with terrestrial LiDAR scanning and high-resolution photogrammetry.
• Clean, register and geo-reference the point cloud.
• Convert the cloud into a coordinated BIM (Revit or Archicad is fine; IFC export mandatory).
• Model every structural element, interior surface and MEP run exactly as found; no generic placeholders.
• Provide colour-corrected orthophotos for façades to assist the heritage team.

Deliverables
1. Raw and registered point-cloud files (.e57 or .rcs).
2. Native BIM file + federated IFC.
3. Orthophoto elevations (TIFF + PDF).
4. Brief report describing scan settings, control points and modelling assumptions.

Acceptance criteria
• Dimensional deviation not exceeding ±5 mm across the scan area.
• All rooms, beams, columns, rafters, pipes, ducts and equipment present in both plan and section views.
• Model opens error-free and passes a basic clash detection in Navisworks.

Please indicate the equipment you plan to use (scanner model, software pipeline) and the anticipated field-to-finish timeline.
