What Is 3D Laser Scanning?
What is 3D laser scanning, and why is it so widely used in modern surveying and construction?
If you’re planning, designing, or building, accuracy is everything. 3D laser scanning is the technology that makes this possible.
In this video, our survey expert Dan talks through what 3D laser scanning is and everything you need to know for your project/
Defining 3D Laser Scanning
3D laser scanning captures precise 3D spatial data of real world objects and environments. It works by firing millions of laser pulses per second, measuring the distance to surfaces and generating a ‘point cloud’, a digital replica of the real world.
At Laser Surveys, we use high-performance scanners from FARO, Leica, Trimble and NavVis.
- Depending on the project, we deploy:
- Tripod-based scanners
- Mobile SLAM scanners
- Drone-mounted LIDAR scanners

Benefits of 3D Laser Scanning and why its ideal for surveying & construction
For surveyors and construction professionals, laser scanning delivers:
- Highly accurate data
- Rapid data collection – Ideal for busy or restricted sites where time on site needs to be minimised.
- No contact measurements – scanning doesn’t require physical contact or proximity to the object being surveyed
- Creates a comprehensive digital record of a site.
- Scanners capture the entire environment by default, reducing the need for return visits.
- Seamless integration with Revit, AutoCAD, and other design tools which can provide highly realistic visualisations.

What are point clouds used for?
From point cloud data we generate Topographical and Measured Building Surveys (Floor Plans, Elevations and Sections) or use them to create 3D Revit models
Plus, 360° online viewers lets you explore the site virtually, take measurements, and share feedback with no special software needed.
