Source record

Authored evidence brief with source evidence for reading on this site. Original English references appear at the end. This is not a full translation of those sources.

Reported comparison

Sundt’s 2021 example compares two people for four hours with one inspector for thirty minutes for a selected inspection. Do not apply that task’s labor comparison to the total construction project.

05 / Limits and failure modes

Reflective surfaces, hidden geometry, motion blur and inconsistent coordinates can invalidate a model. Reconstructed surfaces are not automatically manufacturing drawings or NC toolpaths.

Proposed verification

Proposed acceptance: checkpoint accuracy, coverage, reconstruction completeness, reflight rate and total labor-hours to an approved deliverable. Set tolerances for the actual BIM or survey use.

01 / Start with the work

Record survey setup, access, acquisition, processing, missing-view checks and rework. A short flight is not the same as a finished, accepted model.

02 / Proposed operating flow

The operating flow and acceptance plan below are engineering proposals, not a reconstruction of undisclosed customer procedures.

1. 01Agree model purpose and coordinate frame
2. 02Plan coverage and independent checkpoints
3. 03Capture images and timing records
4. 04Reconstruct and assess completeness
5. 05Review as-built differences and handover

03 / What the buyer receives

Deliver the model, source imagery, coordinate definition, checkpoint residuals and a change register. Visual similarity alone is not dimensional acceptance.

06 / Decision and responsibility

Candidate roles: survey or VDC lead specifies quality; project manager approves the deliverable; procurement engages the survey/integration provider.

07 / Prepare a scoped request

Potential RFQ: stable camera mounts, timing integration or missing-view review tools. Provide sample imagery, design model, coordinate system and accepted output format.
