FAQ
Frequently asked questions.
Common formats include E57, RCP, RCS, LAS, LAZ, and XYZ. A representative sample should be reviewed before scope and price are confirmed.
Yes, where the data has suitable scale, coverage, registration, and geometric quality for the intended model use.
Significant irregularity can be represented when it is relevant to the project. The method and tolerance should be agreed before modelling because exact free-form representation can make files very heavy.

Glossary
Key terms.
HBIM

Point cloud
A three-dimensional collection of measured points created by laser scanning, photogrammetry, or other reality-capture methods.
As-built model
A model representing observed existing conditions rather than an idealised design intent.
openBIM / IFC
Open standards and workflows that support model exchange between different software platforms and project participants.
