A 3D laser scanning survey is a non-contact measurement method that captures the geometry of physical environments using laser technology. Unlike traditional surveys that measure individual points, laser scanning captures millions of points per second, creating a comprehensive digital representation of the scanned space.
How It Works
- Setup: A laser scanner (such as the Trimble X12 or FARO Focus Premium) is placed on a tripod at strategic positions throughout the space
- Scanning: The scanner emits thousands of laser pulses per second, measuring the distance to every surface. Each position takes 3-8 minutes to capture
- Registration: Multiple scan positions are aligned (registered) into a single coordinate system using overlapping geometry and/or survey control points
- Processing: The raw scan data is cleaned, colorized, and exported in the required format
- Delivery: The registered point cloud is delivered in industry-standard formats (E57, LAS, RCP)
What Makes It Different from Traditional Surveying
| Feature | Traditional Survey | 3D Laser Scanning |
|---|---|---|
| Data density | Individual points | Millions of points |
| Speed | 50-100 points/hour | 2+ million points/second |
| Return visits | Often needed for missed measurements | Rarely needed — full coverage |
| Documentation | 2D sketches + measurements | Complete 3D digital replica |
| Accuracy | ±3-10mm (depends on method) | ±1-4mm |
Common Applications
- As-built documentation for renovations
- Construction progress verification (scan vs. design)
- Historic preservation and heritage documentation
- Facility management and space planning
- MEP (mechanical, electrical, plumbing) documentation
- Legal and insurance documentation
- BIM model creation from existing conditions
What You Receive From THE FUTURE 3D, you receive a registered, quality-checked point cloud in your preferred format. This data can be viewed in free software (such as Autodesk ReCap or CloudCompare) or imported into Revit, AutoCAD, or any BIM/CAD platform for further use.
Cost 3D laser scanning surveys typically cost $0.20-$0.70 per square foot, with minimums starting at $1,000 for small projects.
