List every inspection and test for a scope of work, who does it, against what standard and how it is recorded.
An ITP turns quality requirements into a checklist of inspections. It is common in construction, manufacturing and installation work.
Acceptance criteria come from your contract, specifications and applicable standards.

| Field | What to write |
|---|---|
| Activity | Concrete pour, slab |
| Criteria | Rebar spacing and cover per drawing S-201 |
| Point | Hold, engineer sign-off |
| Record | Pre-pour inspection form |
An electrical contractor’s ITP for a new switchboard includes visual inspection on delivery, insulation resistance tests after installation as a witness point, and a hold point before energizing. Each record is filed in the project quality folder.
An ITP shows the owner, before work starts, how each requirement in the specification will be checked and recorded. It reduces rework by catching failures at the stage they happen, instead of after later work has covered them up.
| Project | Northgate Water Treatment Plant, Denver CO |
|---|---|
| Scope | Process piping, 6 in stainless lines |
| Activity | Weld visual inspection, 100% of joints |
| Acceptance criteria | Per ASME B31.3, no cracks or undercut beyond limit |
| Hydrostatic test | 1.5x design pressure, 10 min hold, witness point |
| Hold point | No insulation until hydro test signed off |
| Records | Weld map and test report, filed by QC Lisa |
The hydro test is a witness point so the client can watch, while the insulation step is a hold point because covering the pipe would hide any leak. Each activity names the standard the inspector will judge against.
Often required by contracts.
Work stops until sign-off.
The contractor’s quality lead.
Raise a non-conformance report.
At a hold point, work must stop until the named party has inspected and signed off, so the next stage cannot start without that release. At a witness point, the client or engineer is given notice and may attend, but work can continue if they choose not to come. Mark which one applies to each activity on the plan.
The contractor or subcontractor doing the work usually prepares the ITP, often the quality manager or project engineer, and submits it for client or engineer approval before work begins. It is based on the project specification, drawings and referenced standards. Approved ITPs are revised if the scope or specification changes.
