Progress monitoring
A quick SLAM walk each week produces a dated point cloud of the works. Stacked over time, these show exactly what was built when — objective evidence for progress claims, coordination and disputes, captured in minutes rather than hours.
As-built vs BIM verification
Overlay the SLAM cloud on the BIM model to verify that what was built matches design. Misplaced penetrations, out-of-tolerance slabs and clashes show up immediately — while they are still cheap to fix.
Workflow on a live site
Plan a safe looped route, scan around active work, close loops, and georeference to site control so each scan aligns to the same coordinates and to the model. Export to your coordination tool. Centimetre accuracy covers monitoring and most verification; confirm in the accuracy guide.

Can a SLAM scanner monitor construction progress?
Yes. A weekly SLAM walk captures a dated point cloud of the works in minutes; comparing scans over time gives objective progress evidence for coordination and claims.
Can I compare a SLAM scan to my BIM model?
Yes. Georeference the SLAM cloud to site control, then overlay it on the BIM model to verify as-built versus design and flag clashes or out-of-tolerance work early.
How accurate is SLAM for construction verification?
At 1–3 cm relative accuracy, SLAM suits progress monitoring and most as-built verification. For millimetre-critical checks, supplement with a total station or terrestrial scanner.
