Photo Verification & Remote Inspection
Photo-based verification and remote inspection use images and video to document a setup against the approved plan. They can add coverage and a record, but they supplement rather than replace the required inspection process.

What It Is
Photo-based setup verification uses dated, located photos to document that a setup matches the approved plan.
Remote inspection concepts use images or video to review a setup without being on site, where the agency's process allows it.
How It Is Used
- To create a time-stamped record of the setup at installation and through the work.
- To document corrections and confirm they were made.
- To extend review coverage across more locations or times.
Why It Matters
- A clear photo record helps confirm the setup matched the plan and supports the field packet.
- Wider coverage can catch drift in a setup between formal inspections.
Considerations & Limits
- Whether remote inspection is accepted is set by the agency and the project — it does not replace required on-site inspection unless the agency allows it.
- Photos must be accurate, dated, and located to be useful as a record.
- A record supplements, but does not substitute for, correcting a real deficiency.
