ITP vs ITC
An inspection and test plan (ITP) is the document that plans the quality checks for a scope of work, listing each inspection and test, its acceptance criteria, its hold and witness points and who is responsible; an inspection and test checklist (ITC) is the completed record that evidences those checks were actually carried out, capturing the date, the result, any defect and the sign-offs. In short, the ITP is the plan and the ITC is the proof: one ITP defines the inspections, and each time the work is built it generates the ITCs (also called inspection and test records, ITRs) that show the plan was followed.
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 inspection and test checklist (ITC) is the completed record that proves the inspections and tests set out in the ITP were actually carried out and passed. Where the ITP plans the checks, the ITC captures the evidence: the date, the method, the measured result, any defect or non-conformance raised, and the signatures of the people who inspected and accepted the work. Many organisations call this record an inspection and test record (ITR), and the two terms are often used interchangeably; some use ITC for inspection and test certificate. Whatever the label, it is a historical record and is not edited once signed, because it evidences what happened at a point in time.
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?
In a tender, an ITP is often a returnable deliverable you must submit with the bid, while the ITCs are quality records produced later, during execution. Many scopes of work and conditions of contract require a draft or project-specific ITP as part of the returnable schedules or the supplier data requirements list (SDRL), so the buyer can see how you will control quality before they award. The completed ITCs (or ITRs) are then handed over progressively as the work proceeds and bundled into the final quality dossier or manufacturing record book at completion. Reading a tender, the key is to separate the two obligations: the ITP you commit to at bid time, and the ITC evidence you must produce and hand over later. Elora Grid pulls both out of the scope for you: it reads the SoW and quality specification, extracts every ITP and ITC requirement as its own clause, cites each to its source document and page, and maps it into your compliance matrix and returnables, so a quality requirement is not missed before submission. The judgment on how you will meet each one stays with your engineers.
Common questions
Does ITC mean inspection and test checklist or certificate?
ITC most commonly stands for inspection and test checklist, the record that evidences the inspections and tests in an ITP were carried out. Some organisations use ITC for inspection and test certificate, and many use inspection and test record (ITR) for the same document. The exact label varies by company and region, but the function is constant: a completed record proving a planned check was done and passed.
Which comes first, the ITP or the ITC?
The ITP comes first. The inspection and test plan is prepared before work starts and defines every check, its acceptance criteria and its hold and witness points. The ITC, or inspection and test record, is created during and after the work as each planned check is carried out and signed off. In other words the ITP sets the requirements and the ITCs accumulate as the evidence that those requirements were met.
Is an ITP a returnable schedule?
An ITP is often required as a returnable at bid time, but it is not itself the returnable schedule. The returnable schedules are the buyer's forms you complete and return with the bid; a project-specific ITP is frequently one of the documents those schedules or the SDRL call for. So you may submit an ITP as part of your returnables, alongside priced schedules and compliance statements, without the ITP and the returnable schedule being the same thing.
Who is responsible for the ITP and the ITCs?
The contractor or supplier doing the work usually prepares the ITP and completes the ITCs, while the client, their representative or a third-party inspector reviews and signs off at the nominated hold and witness points. Responsibilities are written into the ITP itself: one column names who carries out each check and who verifies it, so there is a clear record of accountability for every inspection and test on the job.
