Interior geometry
Review reconstructed visible surfaces for the selected manhole or accessible space.
Underground Infrastructure
Build spatial records of accessible underground infrastructure.
Document manhole interiors and accessible underground spaces with a capture plan suited to visibility, access, and the intended inspection record. Combine spatial outputs with the asset information your team already maintains.
The project challenge
Define what can be observed before selecting the equipment.
Manholes, accessible chambers, and larger underground spaces have different geometry and operating constraints. Establish the required coverage and access method first, then select the capture and processing workflow for each part of the program.
Useful deliverables
Define the record your team needs.
Dated condition records
Keep inspection identifiers and capture dates with each delivered dataset.
Comparison inputs
Plan alignment and comparable coverage before attempting before-and-after review.
From planning to handover
A workflow for underground infrastructure.
- 01
Define asset boundaries
Identify openings, accessible spaces, required surfaces, and known access constraints.
- 02
Plan suitable capture
Separate dedicated manhole collection from any operator-accessible scanning route.
- 03
Reconstruct and align
Check the processed result and the coordinate basis required by the project.
- 04
Archive and review
Deliver the agreed files with asset identifiers, dates, and coverage limitations.
Project requirements
Agree these requirements before capture.
- Access conditions. Select equipment and procedures around the environment and authorized access.
- Direct visibility. Concealed infrastructure cannot be inferred solely from a surface scan.
- Repeat visits. Agree reference positions and matching coverage for later comparison.
- Asset handover. Confirm formats, coordinate context, and any inspection report fields before collection.

Does this provide a map of all buried infrastructure?
Scope the record around observed surfaces and supplied asset information. Buried or inaccessible routes require separate evidence and investigation.
Can repeated scans show changes?
Plan comparable coverage, a consistent reference, and an agreed assessment method. Differences in capture or processing must be considered during comparison.
