What Is an Inspection and Test Plan (ITP)?
An Inspection and Test Plan (ITP) is a quality document that lists, in the order work happens, every inspection and test needed to check it meets the drawings, specification and any relevant Australian Standards. Each line records the acceptance criteria, whether it’s a hold, witness or review point, and who has to check and sign off before the next stage can begin. It’s the working checklist that turns a project’s quality requirements into something a site team can actually run against, day to day.
Key takeaways
- An Inspection and Test Plan (ITP) sets out, in the order work happens, every inspection and test needed to check it meets the drawings, specification and applicable standards.
- Each line of an ITP records the acceptance criteria and is classified as a hold, witness or review point, which decides whether work can proceed before sign-off.
- ITPs are usually drafted by the contractor’s site or quality team and reviewed by the superintendent or client’s representative before work starts.
- A completed, signed ITP becomes part of the project’s quality records and is often required at practical completion and handover.
What is an Inspection and Test Plan?
An Inspection and Test Plan (ITP) is a structured, sequential document that lists every inspection and test a specific work activity — a concrete pour, a stormwater line, a fire-rated wall — needs to pass to demonstrate it meets the drawings, specification and any Australian Standards that apply. It works alongside a company’s quality management system, turning written project requirements into a checklist a supervisor can tick off on site.
Rather than a general promise that work will comply, an ITP forces the compliance question down to specific, checkable points: what is being checked, against what standard, by whom, and what happens if it fails.
In plain terms
An ITP is the checklist a supervisor runs through, activity by activity, to prove the work actually meets the spec — not just that it looks finished.
What an ITP includes
A typical ITP is laid out as a table, with one row per inspection or test point in the order the work will happen. Each row usually captures:
- The activity or work stage being checked, referenced back to a drawing, specification clause or Australian Standard.
- The inspection or test method — a visual check, a measured test, a survey, a laboratory result.
- The acceptance criteria — the tolerance, standard or result the work has to meet to pass.
- A classification of hold, witness or review point, which sets whether work can continue before sign-off.
- A column for the inspector’s name, date and signature, creating an auditable record.
| Activity | Reference | Check/Test | Acceptance Criteria | Point Type | Sign-off |
|---|---|---|---|---|---|
| Reinforcement fixed | Drawing S-101 | Visual/measure | Cover & spacing per drawing | Hold | Site Engineer |
| Formwork erected | Spec 03.10 | Visual | Level & alignment ±5mm | Witness | Supervisor |
| Concrete placed | AS 1379 | Slump test | Slump within spec range | Hold | QA Rep |
| Curing complete | Spec 03.10 | Visual/record | Curing period met | Review | Site Engineer |
Hold points, witness points and review points
Every line on an ITP is classified so the site team knows how much notice to give and whether work can proceed before someone checks it. A hold point is the strictest of the three — work cannot continue past it until a nominated party has inspected and approved it. A witness point invites the same inspection, but work can proceed if the nominated party doesn’t attend after reasonable notice. A review point is usually a desktop check of records rather than a physical site inspection.
Getting this classification right matters commercially as much as technically — treating a hold point as a witness point is a common, expensive ITP mistake, since it can mean exposing or redoing completed work.
Who prepares and signs off an ITP?
The contractor’s site supervisor or quality manager typically drafts the ITP from the project specification and the standards it references, then submits it to the superintendent or client’s representative for review and approval before the relevant work starts.
From there, sign-off happens progressively as each point is passed, with the completed, signed ITP becoming part of the project’s quality records — commonly required at practical completion and handover.
Where an ITP fits alongside your tender
My Trade Hub doesn’t prepare or manage your ITP — it’s a quality document your own quality system produces. But a competitive tender submission is judged on more than price, and clients increasingly expect to see your quality approach set out alongside your priced Bill of Quantities and scope of works.
Using My Trade Hub’s tender document templates, you can keep supporting documents like your ITP organised alongside your automated takeoff, editable rates and priced BOQ, so the whole submission goes out as one professional package rather than a scattered set of attachments.
Frequently asked questions
What does ITP stand for in construction?
ITP stands for Inspection and Test Plan — a document that lists every inspection and test a work activity needs to pass, in sequence, to demonstrate it meets the drawings and specification.
What is the difference between an ITP and a hold point?
An ITP is the whole document; a hold point is one specific line within it — a mandatory stop where work cannot proceed until a nominated party has inspected and approved it.
What is the difference between an ITP and a SWMS?
An ITP is a quality document checking that work meets the specification and standards. A Safe Work Method Statement (SWMS) is a safety document identifying hazards and controls for high-risk construction work. They cover different risks and are usually kept as separate documents.
Who signs off an ITP?
Sign-off is progressive: the person nominated against each line — often a site engineer, supervisor or QA representative — inspects and signs as each point is reached, with the superintendent or client’s representative approving the ITP itself before work starts.
