Scan to BIM
Scan to BIM: surveying existing buildings and structures by laser scan and turning the result into a verifiable as-is model.
From laser scan to model – the basis for any work on an existing building where the old drawings are wrong. And they usually are.
How it runs
- Survey by laser scan or photogrammetry
- Registration of the point cloud
- Modelling to the agreed level of detail
- Model checked against the point cloud as evidence of accuracy
Settle the level of detail first
An as-is model can capture everything or only the structure. The difference in effort is large; the difference in usefulness depends entirely on what you intend to do. So we fix the level before the scan, not after.
