What is an inspection and test plan (ITP)?
An inspection and test plan (ITP) is a document that sets out, before work starts, every inspection and test a scope of work requires and how each will be verified. A typical ITP lists each activity in sequence with its acceptance criteria, the reference standard or specification clause, the verifying document, the responsible party, and the inspection type: a hold point (work stops until a check is signed off), a witness point (a party is invited to attend but work may continue), or a surveillance or review point. The ITP is a live document: it is reviewed and updated as the scope, sequence or standards change, and it acts as the roadmap for quality on the job.
What is an inspection and test checklist (ITC)?
An ITC or ITR records the checks performed under an ITP: the date, method, measured result, pass or fail status, defects, corrective action and relevant signatures. Some organisations use ITC to mean inspection and test certificate. Use the project's terminology and retain the completed record; record an authorised correction rather than silently rewriting signed evidence. A completed record can show a failure as well as a successful result.
What is the difference between an ITP and an ITC?
The difference between an ITP and an ITC is that the ITP plans the inspections and the ITC records them. The ITP comes first and is forward-looking: it defines what will be checked, against what criteria, by whom, and at which hold and witness points. The ITC comes during and after the work and is backward-looking: it is the filled-in evidence that each planned check was done and the result it gave. One ITP generates many ITCs, because the same plan is executed every time that scope is built or installed. The ITP can be revised as the job changes; a completed ITC is fixed, a quality record you keep. Put simply, you write one ITP to say how quality will be controlled, then collect many ITCs as proof that it was.
How do ITPs and ITCs show up in a tender?
A tender may require a draft ITP with the bid and completed ITCs or ITRs during manufacture, installation or handover. Capture both obligations in the package scope, including hold points, witness points, evidence and responsibility. Elora Grid can help extract these requirements from the project files and carry them into supplier enquiries. The contractor records actual test results; AI-generated text is not evidence that a test occurred.
