3D Laser Scanning & LiDAR
Point cloud survey, as-built documentation, and deformation analysis
Overview
3D laser scanning and LiDAR capture millimetre-accurate geometry of existing buildings, bridges, facades, slabs, and heritage assets. The registered point cloud records the structure as it exists on site, including deformation, level changes, tilt, and hard-to-measure geometry that drawings often miss.
For structural investigation, LiDAR gives engineers the geometric baseline needed for capacity checks, refurbishment planning, and change-of-use reviews. When original drawings are missing or unreliable, SiteOps uses point cloud survey data to produce as-built plans, sections, elevations, and measurement outputs that design teams can rely on.
LiDAR is also valuable for deformation analysis. By comparing scanned geometry against design geometry or repeat scans, SiteOps can quantify deflections, tilts, bulges, settlement, facade movement, and other structural changes with a traceable spatial record.
SiteOps positions LiDAR as part of structural investigation, not as generic visualisation. We can provide registered point clouds, 2D CAD extraction, 3D model inputs, and geometry suitable for finite element analysis or consultant coordination where that deliverable is in scope.
Applications
Point Cloud Survey
Registered point cloud capture for existing buildings, facades, bridges, slabs, and complex structural geometry.
As-Built Documentation
Measured floor plans, sections, elevations, and geometry outputs where original drawings are missing or unreliable.

FAQ
Common questions
When does SiteOps use LiDAR scanning?+
SiteOps deploys LiDAR when accurate as-built geometry is needed: no original drawings, suspected deformation, heritage recording, complex facades, refurbishment coordination, or point cloud survey inputs for engineering review.
How accurate is LiDAR scanning?+
Survey-grade terrestrial LiDAR achieves ±1–2mm accuracy at 10m range under normal conditions.
Can LiDAR be used in occupied buildings?+
Yes. LiDAR uses eye-safe laser pulses and can be performed in occupied buildings during normal operations.
Does SiteOps provide scan-to-BIM?+
SiteOps can provide registered point clouds, 2D CAD extraction, and 3D model inputs for consultant coordination. Full Revit modelling or LOD-specific BIM authoring is confirmed by scope so clients know exactly what deliverable they are receiving.
