What Is Scan to BIM?
Scan to BIM captures a building's existing geometry using 3D laser scanning, then converts the point cloud into an intelligent parametric BIM model — typically Revit or IFC — with elements categorised by discipline. Each laser pulse records millimetre-accurate positions; the resulting point cloud is modelled into walls, floors, MEP systems, and structural elements.
When to Use It
- Refurbishment and renovation — when existing drawings don't exist or are untrustworthy
- Heritage and listed buildings — non-contact capture avoids physical interference with protected fabric
- MEP clash detection — verifying new services fit around existing structure before fabrication
- Extensions and fit-outs — ensuring new elements match what's actually on site
- As-built verification — confirming constructed works match design intent at handover
- Facilities management — creating a digital twin for ongoing asset management
- NEC4/procurement — providing verified existing conditions as a contract document to reduce contractor risk

Frequently Asked Questions
Q: When should I commission scan-to-BIM?
Commission it when existing drawings are absent, outdated, or untrustworthy — especially for refurbishments, heritage works, MEP coordination, or any project where existing conditions affect design or construction risk.
Q: What LOD do I need?
LOD 200–300 for most refurbishments. LOD 350–400 for MEP-heavy projects, plant rooms, or prefabrication. LOD 500 for FM and asset management.
Q: What deliverables do I receive?
Registered point cloud files (E57/RCS/LAS), Revit or IFC BIM model to agreed LOD, deviation reports, and 2D CAD drawings on request.
Q: What does scan-to-BIM cost near me?
Small residential: £800–£2,500. Commercial floors: £3,000–£10,000+. LOD 300 modelling: ~£7/m².
