What Is a Point Cloud Survey?
A point cloud survey uses 3D laser scanning to capture millions of precise measured points (x, y, z coordinates) to create a detailed digital record of a building, structure, or site. Multiple 360° scan stations are registered and stitched into one complete point cloud. 3D laser scanners capture 500,000+ points per second at 1–3mm accuracy.

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 ±1–3mm 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 .PTX for point cloud data. BIM models are delivered in .RVT (Revit) and .IFC formats. 2D drawings in DWG and PDF.
