What Is a Point Cloud Survey?
A point cloud survey uses LiDAR/3D laser scanning to capture millions of precise 3D data points of a building or site to create an accurate digital record. Multiple scan positions are combined through point cloud registration into one complete dataset with millimetre accuracy.
Costs in Ealing/London (2025)
| Project Type | Price Range (ex VAT) | | --- | --- | | Small projects | £250–£1,000+ | | Average UK survey | £500–£5,000+ | | Day rate (surveyor) | From £1,000/day | | Point cloud only | £750–£1,250/day | | Point cloud + 2D CAD | £1,000–£2,000 per drawing |
Cost factors: Property size and complexity, point density (higher density = larger files, more processing), colour vs. black and white (colour adds ~40%), site accessibility, and post-processing time.
Deliverables
| Deliverable | Format | Use | | --- | --- | --- | | Raw point cloud | .E57, .RCP, .LAS | Direct scan data | | 2D CAD drawings | .DWG | Architectural plans | | BIM models | .RVT | Revit models | | SketchUp models | .SKP | 3D modelling | | As-built plans | CAD | Planning applications |
Point clouds are intelligent datasets requiring interpretation by experienced technicians. They form the basis for creating 2D/3D surveys and can be supplied as raw data.

Frequently Asked Questions
Q: What is the difference between a point cloud and a BIM model?
A point cloud is raw 3D scan data — millions of measured points. A BIM model is an intelligent, object-based representation where walls, doors, MEP services etc. are categorised and parametric. Point cloud data can be used directly in Navisworks for clash detection, or modelled into a Revit BIM model.
Q: What accuracy can I expect from point cloud scanning?
Modern terrestrial LiDAR scanners achieve ±1–2mm accuracy. Accuracy depends on scan density, reflector placement, and scan distance from the instrument.
Q: What file formats do I receive?
Standard formats include .e57, .RCP/.RCS, .LAS, and .PTS for point cloud data. BIM models are delivered in .RVT (Revit) and .IFC formats. 2D drawings in DWG and PDF.
