What Is Scan-to-BIM?
Scan-to-BIM converts raw point cloud data — captured by terrestrial laser scanners, mobile LiDAR, or drone — into an intelligent, parametric 3D model in Revit. Elements are categorised by discipline (architectural, structural, MEP) with properties and system relationships, integrating directly into the project's Common Data Environment (CDE).
Two-Phase Workflow
Every scan-to-BIM project has two distinct, separately priced stages:
- Laser scanning (data capture) — Scanner captures millions of points producing a registered cloud (±3–10mm). Delivers E57, RCP, or LAS files.
- BIM modelling — Revit specialist imports the point cloud and traces parametric objects — this is the labour-intensive, higher-cost phase.
Scanning typically takes **1–3 days on-site; modelling and QA takes 10–15 working days for a standard multi-discipline model.
LOD Levels Explained
| LOD | Label | Geometry | Accuracy | Typical Use | | --- | --- | --- | --- | --- | | LOD 100 | Conceptual | Massing only | ±1,000mm | Feasibility, early studies | | LOD 200 | Schematic | Approximate size/shape | ±500mm | Space planning | | LOD 300 | Detailed Design | Accurate dimensions | ±100mm | Design development, QTOs | | LOD 350 | Construction Docs | Interfaces between systems | ~±50mm | Clash detection | | LOD 400 | Fabrication | Manufacturer-specific | ±10mm | Fabrication, prefabrication | | LOD 500 | As-Built | Actual installed conditions | ±5mm | FM, asset management |
Most UK refurbishment projects land in the LOD 200–300 range. UK providers typically issue deviation reports with every model delivery — colour-coded overlays showing where geometry falls within or outside tolerance.
Accuracy: What to Expect
| Measurement | Accuracy | | --- | --- | | Registered point cloud | ±2–5mm | | BIM model (LOD 300) | ±10–20mm deviation from cloud | | BIM model (LOD 500) | ±5mm or better |
Three common tiers used in UK practice:
- ±3–5mm (high precision — fabrication, prefabrication coordination
- ±10mm (medium — most architectural and structural modelling
- ±20mm (general — early-stage planning, space layout
Modelling Scope and Cost
| Scope | Typical Cost (ex VAT) | | --- | --- | | Architectural elements only | ~£7/m² | | Full MEP modelled | ~£10/m² | | Deviation report | Included or £200–£500 per floor/zone |
Frequently Asked Questions
Q: What LOD do I need for a refurbishment project?
LOD 200–300 is typical for most UK refurbishments. Specify LOD 350–400 if you need clash detection or prefabrication coordination. LOD 500 for FM and asset management.
Q: How accurate is a Revit model from point cloud?
Registered point cloud: ±2–5mm. BIM model (LOD 300): ±10–20mm deviation from the cloud. LOD 500: ±5mm or better.
Q: What is the biggest cost driver in scan-to-BIM?
Modelling scope — specifically whether you need full MEP modelling or just architectural elements. Post-processing modelling typically exceeds the on-site scan cost.
