3D laser scanning· Raw and registered point cloud
3D laser scanning for architecture and building surveys
An architectural 3D scanner on site, a usable point cloud in your hands.
We survey existing buildings with mobile and static laser scanners. The output is a registered point cloud in E57 or RCP, accurate to the millimetre, that drops straight into Revit, ArchiCAD, AutoCAD or Recap. No assumptions, no cumulative tape-measure error, and nothing missed because it was hard to reach.
Why GUYENNE ÉTUDES for 3d laser scanning
- Mobile scanner for dense, awkward interiors; static long-range for large volumes
- Scanning does not depend on ambient light — cellars and plant rooms are no obstacle
- The cloud stays consultable: a dimension missed on site does not mean a second visit
- Occupied buildings surveyed out of hours where needed
What you receive
- Registered point cloud (.e57)
- Recap-ready point cloud (.rcp)
- Coloured or intensity-mapped cloud
- Coordinate system and control notes
- Ortho-images of facades and floors on request
Typical projects
- Architectural surveying of a building with no drawings
- Recording complex or listed facades before design work
- Industrial plant survey: structure, overhead services, clearances
- Verification of built work against the design model
- Basements, vaults and voids where measuring by hand is impractical

How accurate is a laser scan survey?
Millimetre-level on the registered cloud. In practice the limiting factor is rarely the scanner: it is whether every surface was captured. We plan station positions so that nothing structurally relevant is left in shadow.
Which file formats do you deliver?
E57 as the open standard, RCP for Autodesk workflows. We can also supply ortho-images and 2D DWG extractions from the same survey if that is more useful than the raw cloud.
Can you scan a building that is still occupied?
Yes, and we do it regularly on offices, shops and apartment blocks. Scanning is quiet and needs no drilling or dismantling. Evening or weekend visits are possible where daytime access is disruptive.
