Reality Capture & BIM
Drawings describe intent. A scan describes the building. Petra Point captures built condition by 3D laser scanning, registers the survey to control, and delivers it in a working format: point cloud, 2D documentation, 3D CAD, or a coordinated BIM model.
When you need this
- 01As-built condition differs from the design set, and the difference matters.
- 02A refurbishment, fit-out or extension needs a reliable base model.
- 03Areas must be taken from the building itself, not from the drawings.
- 04A BIM model is required but no dependable existing-condition data exists.
What you receive
- Registered point cloud
- As-built survey report
- 2D plans, elevations and sections
- 3D CAD model
- BIM model at agreed level of detail
In detail

3D Laser Scanning
We scan the building as it stands and register the survey to control. What comes off it is your choice: point cloud, drawings, 3D CAD or a BIM model.
- 03.02
As-Built & Measured Building Surveys
A measured record of what was actually built. Drawn from survey of the building rather than traced from the drawings it was meant to follow.
- 03.03
Scan to BIM
A BIM model of a building that already exists, built from a survey of it rather than from the drawings it was supposed to be built to.

Point Cloud Deliverables
The measured record a laser scan produces, what makes it usable, and what gets drawn from it.
