What Is a Point Cloud Survey?
A point cloud survey uses LiDAR technology to capture millions of data points — each with precise X, Y, Z coordinates — creating an accurate digital twin of a building, structure, or landscape. Scanners capture up to 1 million points per second with accuracy within 2mm tolerance at over 300 metres range. Think of it as a site photograph you can actually measure.

London Cost Guide (2025)
| Project Type | Typical Cost (ex VAT) | | --- | --- | | Small/simple building (point cloud only) | £250–£1,000+ | | Traditional measured survey (comparison) | ~£2,000 | | Full 3D laser scan with point cloud output | ~£3,500 | | Large/complex or multi-floor buildings | £5,000–£10,000+ |
The premium over traditional surveys is widely considered commercially justified — a single steel frame rework event typically costs far more than the difference.
Key Cost Drivers
- Site size and scanner positions — more area = more setups
- Access constraints — live environments, confined spaces, height
- Required LOD — concept design vs. fabrication-level detail
- Deliverables — raw point cloud vs. full Revit/BIM model
Frequently Asked Questions
Q: What is a point cloud survey?
A LiDAR-based digital capture of millions of measured XYZ coordinates forming a precise 3D digital twin that can be measured and modelled in any software.
Q: What accuracy does a point cloud achieve?
Professional scanners achieve ±2mm accuracy at 300m+ range — well within all construction documentation tolerances.
Q: What deliverables can I get from a London point cloud survey?
Point cloud files (.e57, .rcp, .las), 2D AutoCAD drawings, 3D Revit/BIM models (LOD 200–500), IFC/COBie for FM, and drone aerial scans for rooflines.
Q: What does a point cloud survey cost in London?
Small buildings: £250–£1,000+. Full 3D laser scan with point cloud: ~£3,500. Large/complex buildings: £5,000–£10,000+. London adds 15–30% over provincial rates.
