What is an ITP in construction?

An Inspection and Test Plan (ITP) is a quality assurance document used in construction to define inspection activities, hold points, and witness points at key stages of work. It specifies what needs to be checked, by whom, and records the results for audit and compliance purposes.

How much does HoldPoint QA cost?

HoldPoint QA charges $45 AUD per active project per month for 1–5 projects, and $35 per project per month for 6 or more active projects. There are no per-seat fees or per-document charges. Projects start as draft (free) until the first document is added.

Can external clients sign ITPs without an account?

Yes. HoldPoint QA sends a secure sign-off link via email. External signatories — clients, principal's representatives, or engineers — can review the full ITP checklist and sign digitally without needing an account or app.

Does HoldPoint generate ITP PDFs automatically?

Yes. When an ITP is approved, HoldPoint automatically generates a branded PDF containing all checklist results, inspection notes, photos, and signatures. PDFs are regenerated if any information changes.

What are the key hold points for a roofing ITP?

The critical hold points are sarking/underlay installation (before sheeting covers it), flashing and penetration sealing (before trim and accessories conceal them), and any specified water testing. These are stages where defects are concealed by subsequent work and cannot be re-inspected without destructive investigation.

Is a water test required for roofing?

A water test (hose testing) is not always contractually required but is strongly recommended, particularly for complex roof geometries, membrane roofing, and areas with multiple penetrations. Where specified, it should be a hold point in the ITP with the test method, duration, and result recorded.

Do metal roofing and membrane roofing need separate ITPs?

If your project has both metal roofing and membrane roofing (e.g. Colorbond on pitched areas and a torch-on membrane on a flat podium), they should either be separate sections in the same ITP or separate ITPs. The inspection criteria, hold points, and applicable standards differ significantly between the two systems.

Background

What is a Roofing ITP?

A roofing ITP covers the inspection and testing requirements for roof installation — including structural support, sarking, sheeting or membrane installation, flashing, penetration sealing, guttering, and downpipes. It ensures that every stage of the roofing scope is inspected and recorded, with hold points at concealment stages.

Roofing defects are among the most common and costly construction defects. Leaks that develop months or years after completion often trace back to poor flashing details, inadequate penetration sealing, or incorrect fall gradients. A complete ITP with photographic evidence at each inspection stage is critical protection during the defect liability period.

In Australia, roofing ITPs should reference the relevant product manufacturer's installation guide, AS 1562 (Design and Installation of Sheet Roof and Wall Cladding), and any project-specific waterproofing and thermal performance requirements.
