Inspection and test plan (ITP)
An ITP is the map of quality checkpoints for a scope of work. For each activity it names the inspection or test, the acceptance criteria, who is responsible, and — critically — the hold and witness points where work cannot proceed until a check is signed off. It turns "we'll inspect as we go" into a defined sequence everyone agreed to before the work started.
How it shows up on site
The ITP flags hold points (work stops until inspected) and witness points (a party is notified and may attend) at the moments that matter — before a pour is covered, before a rough-in is closed up, before an assembly is concealed. It ties each checkpoint back to the governing standard family and the checklist used to run the check, so the field crew and the inspector are working from the same expectations.
What proves it
A signed ITP line with its supporting record — a checklist, a test result, and photos of the condition at the checkpoint — is the evidence that the sequence was actually followed. When checkpoints are photo-gated, a covered assembly always has the pre-cover record behind it instead of a blank line.

Knowing the term is step one. Proving it is the job.
RTI holds the submit button until every mandatory item is answered and the photos are attached, then chains the record so it can be proven untouched later.
