What Is 3D Laser Scanning Survey?
3D laser scanning (terrestrial LiDAR) is a non-contact, non-destructive surveying method that captures millions of precise measurement points to create a detailed 3D point cloud of a building or site. The scanner records exact geometry with millimetre-level accuracy (±2mm), creating a measurable digital twin of the real-world conditions.
Key Deliverables
| Deliverable | Description | | --- | --- | | Point Cloud (raw data) | .e57/.RCP/.LAS/.PTS format; greyscale or RGB colourised | | 2D CAD Drawings | Floor plans, elevations, sections, roof plans | | 3D BIM/Revit Model | LOD 300 (architectural) or LOD 400 (with MEP) | | Virtual Tour/TruView | 360° photographic overlays in point cloud |
The biggest cost factor is usually the deliverables (modelling and drawing time), not the scanning itself.
Costs in Brent/London (2025)
| Project Type | Cost Range (ex VAT) | | --- | --- | | Day rate (point cloud only) | £750–£1,250 per day | | Small residential (3-bed house) | £800–£2,500 | | Medium commercial (office floor) | £3,000–£10,000 | | Large/complex (hospital, factory) | £10,000–£50,000+ | | Point cloud + 2D drawings | £1,000–£2,000 per drawing | | Confined space scanning | £1,200–£2,500 per day |
Factors affecting price: building size and complexity, LOD, access and safety requirements, urgency (+30–50% for express), and deliverables type.

Frequently Asked Questions
Q: What is the difference between a point cloud and a BIM model?
A point cloud is raw3D 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 3D laser scanning?
Modern terrestrial LiDAR scanners achieve ±2mm accuracy at typical scan distances. 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.
