Preserve the useful detail
Require access point, direction, footage counter, full recording, visibility, material, transitions, surface-location method, and the exact feature at issue.
The decision on display
Do not transfer the hazard
Do not excavate from narration alone. Confirm marks, utilities, system type, district, ownership, and permits.
Make the proposed work comparable
The deliverable should include video, stills, distances, direction, surface locate, limitations, diagnosis, alternatives, and reason for opening.
