Decision checklist
- access/isolation start
- field verification
- surface preparation
- repair and repair cure where applicable
- application/installation
- system cure
- inspection/touch-up
- owner-authorized handoff
Why it changes scope
Each input can change preparation, repair quantity, system selection, access, sequence, cure protection, or return-to-service assumptions. Leaving it undefined does not make it disappear; it moves uncertainty downstream.
Contractor boundary
A real project would reconcile the owner/specifier requirements, manufacturer data, field conditions, and any engineering or regulatory responsibilities before execution. This concept does not replace those parties.
Use this before publishing the outage duration
A shutdown window should be decomposed into activities and decision gates. The important question is not “Can coating be applied in this many hours?” but “Can the complete approved sequence, including repair and cure, reach owner-authorized handoff inside the window?”
That distinction protects both operations and scope. It also reveals which quantities or inspections must be verified before the outage begins.
