Why SLAM for as-built
Traditional as-built capture is slow and easy to under-sample — you measure what you remember to. SLAM records everything continuously, so the deliverable is complete and you rarely need a second visit. For a building or floor, that turns a day into an hour.
Accuracy and deliverables
At 1–3 cm relative accuracy, SLAM covers most as-built documentation, floor plans and sections, and feeds scan-to-BIM. From one cloud you can produce 2D plans, elevations, sections, or a full 3D model — choose per client.
Field workflow
Walk closed, overlapping loops covering every room and connection, close your loops, then process and georeference if the as-built must sit on a coordinate system. Export to CAD/BIM and document. See the full SLAM workflow.
Frequently Asked Questions
Is SLAM good for as-built surveys?
Yes — it is one of the best tools for as-built. SLAM captures the entire space continuously in minutes at 1–3 cm, producing complete documentation with fewer return visits.
How accurate is a SLAM as-built survey?
Relative accuracy is typically 1–3 cm, which meets most as-built and documentation tolerances. For millimetre detail on specific elements, add a terrestrial scanner.
What can I deliver from a SLAM as-built scan?
From one point cloud you can produce floor plans, elevations, sections, volumes or a full BIM model — the same scan supports multiple deliverables.
How long does a SLAM as-built survey take?
Often minutes to capture a floor or building — a fraction of the time of manual or total-station methods — plus office processing to clean, georeference and export.
