Point Cloud vs Scan to BIM: UK Decision Guide
Choosing between raw point cloud and full Scan-to-BIM depends on your project stage, in-house capability, and budget. Here is the UK decision guide for 2025.
Quick Decision Summary
| Factor | Choose Raw Point Cloud | Choose Full BIM Model | | --- | --- | --- | | You need | Reference data, measurements, visualisation | Design coordination, clash detection, quantity take-offs | | In-house capability | Have experienced Revit modellers | No in-house modelling team | | Timeline | 3–5 days delivery | 1–4 weeks (now 2–6 weeks with automation) | | Project stage | Early feasibility, survey backup | Design development, construction, FM | | Budget | Lower cost (£750–£1,250/day) | Higher cost (£1,500–£5,000+) |
When to Use Raw Point Cloud Only
Best for:
- Visualisation and reference — 3D walkthroughs, spatial understanding
- DIY modelling — Your team has Revit expertise and will model in-house
- Measurement verification — Taking measurements without interpreted geometry
- Future modelling — Capture now, model later for phased projects
- Simple layouts — Basic floor plans where full BIM is overkill
Deliverables:
- E57, RCP, or LAS files
- Registered, colourised point cloud
- Geo-referenced (if required)
- QC or registration report
When to Use Full Scan-to-BIM Model
Best for:
- Design coordination — LOD 200–300 for architectural, structural, and MEP
- Clash detection — Identify conflicts before construction
- Quantity take-offs — Cost estimation and BOQ generation
- Facilities management — Asset data, warranty dates, COBie format
- Retrofit and renovation — Accurate as-built for complex refurbishment
- MEP-heavy projects — Dense services requiring coordination
Deliverables:
| Format | Purpose | | --- | --- | | Revit (.rvt) | Primary BIM model, discipline-structured | | IFC (.ifc) | Open BIM coordination (Solibri, Trimble Connect) | | DWG extracts | 2D plans and sections for CAD teams | | Point cloud (.e57) | Source data included for reference | | Deviation report | Model-to-cloud tolerance analysis (±5–15mm) |
LOD guidance:
- LOD 200 — Design reference, spatial planning
- LOD 300 — Coordination, design development
- LOD 400 — Fabrication-level (quote required)
2025 UK Cost Comparison
| Service | Price (ex VAT) | Notes | | --- | --- | --- | | Point cloud only | £750–£1,250 per day | Small building: from £1,200 | | Point cloud + 2D CAD | £1,000–£2,000 per drawing | Depends on complexity | | Scan-to-BIM (LOD 300) | £7–£15/m² | Architecture only | | Scan-to-BIM (LOD 350) | £12–£20/m² | MEP coordination | | Full Scan-to-BIM | £15–£30/m² | Multi-discipline | | BIM modelling (hourly) | £50–£150/hour | In-house option |
Quick Decision Checklist
Choose point cloud if:
- [ ] You have in-house Revit modelling capability
- [ ] Project is early feasibility or survey backup
- [ ] You need fast delivery (3–5 days)
- [ ] Budget is limited
- [ ] Simple layout — full BIM is overkill
Choose Scan-to-BIM if:
- [ ] No in-house modelling team
- [ ] Design coordination or clash detection needed
- [ ] MEP-heavy project requiring multi-discipline model
- [ ] Facilities management handover required
- [ ] Planning submission with BIM requirement
Frequently Asked Questions
Q: Can I get both point cloud and BIM model?
Yes — most surveyors deliver the point cloud as source data alongside the BIM model. Point cloud is included in the base price.
Q: Which is faster — point cloud or Scan-to-BIM?
Point cloud: 3–5 days. Scan-to-BIM: 1–4 weeks (now 2–6 weeks with AI automation). AI tools have significantly reduced BIM modelling time.
Q: Can I model from point cloud later?
Yes — capture now, model later for phased projects. The point cloud is retained as source data.
Q: Is Scan-to-BIM worth the extra cost?
For design coordination, MEP-heavy projects, and FM handover, yes — every £1 spent on Scan-to-BIM saves £5–£20 in avoided rework.
