Inspection and test plan (ITP)
An inspection and test plan is the document that lists, for one activity, each inspection or test to be done, the acceptance criterion and the standard it comes from, the record to be kept, and which party holds a hold point or a witness point at each step.
Australian and British quality-management language; an American project may call the same document an inspection plan or a quality control plan. It is the working document behind the project quality plan.
An ITP is written per activity: piling, structural steel, waterproofing, fire doors. The subcontractor signs each step, the builder’s QA signs, and the engineer or client signs the hold points. On paper it is signed in the site office a week after the fact; the value is in signing it at the step, with the evidence.
How IssuesId holds it
The checks on an ITP can be built once as an IssuesId checklist template and run per location, with the hold points marked. Every answer records who gave it and when, a No raises a linked defect, and the stretch a subcontractor is responsible for can be sent to them as a share link with a due date.

Definitions describe common usage and the usual shape of standard-form contracts. Your contract and your jurisdiction’s building law set the terms that apply to your job. The whole list is at the glossary.
