Practical Geo Scan guidance on 3D Laser Scanning for Measured Building Surveys for architects, developers and project teams.
Terrestrial laser scanners measure visible surfaces from a series of positions. Registered scans form a coordinated point cloud of the geometry captured, including agreed building features and visible services. A point cloud is a measured record at the time of capture; it does not by itself constitute a maintained digital twin or reveal concealed features.
Dense capture can reduce uncertainty where a proposed design meets an existing building. It also provides a reusable spatial reference for separately agreed drawing or model production. Coverage and accuracy still depend on the survey methodology, access and checks; obscured areas or later scope changes may require additional attendance.
From capture to CAD, our workflow ensures data integrity.
Surveyors plan overlapping scan positions and control around the agreed coverage, identifying obscured or inaccessible areas.
Raw scans are registered (stitched) into a unified point cloud and cleaned of noise (people, reflections).
The point cloud is sliced to create 2D CAD drawings or used as a reference to build 3D BIM models.

For site capture and registration, explore our 3D laser scanning surveys or 3D laser scanning in London. If you need drawings from our survey, see Scan to CAD services; drawing coverage and detail are separately agreed.
