Structures move — settling, deflecting, shifting. Laser scanning measures it precisely and repeatably.

How it works
Capture a baseline scan, then rescan later and compare. Differences reveal settlement, deflection, or deformation across the whole structure, not just a few points. It relies on survey-grade accuracy.

Where it helps
- Aging or historic structures.
- Adjacent-construction monitoring.
- Post-event assessment.
