Inspection and test plan (ITP)
An inspection and test plan (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.
Guides that use it
- How to write an inspection and test planBuild an inspection and test plan that lists every check and test for a feature, names who releases each, and marks the hold and witness points.
- How to set hold points and witness pointsDecide which steps in an ITP are hard stops and which are invitations to observe, name who releases each, and set the notice periods that make them stick.
- How to set up a QA/QC program on a projectStand up a QA/QC program from scratch: separate quality assurance from quality control, write the QC plan, break the job into features, and assign who inspects what.
