What Is an ITP and Why Does Every Concrete Repair Project Need One?

An Inspection and Test Plan, commonly referred to as an ITP, is a structured quality assurance document used in construction to define the inspection, testing and verification requirements at each stage of a scope of work. In the context of concrete repair and rehabilitation, an ITP records what was done, when it was done, how it was checked, and whether it met the specified acceptance criteria.

What does an ITP contain?

A typical ITP for concrete repair works includes the following elements: a description of each work activity in sequence, the relevant standard or specification reference, the type of inspection required (hold point, witness point, or review point), the responsible party for each inspection, and the acceptance criteria that must be satisfied before proceeding to the next stage.

For example, a hold point might be placed after steel treatment and before mortar application, requiring the engineer or superintendent to physically inspect and approve the prepared substrate before the repair can continue.

Hold points, witness points and review points

Hold point: Work must stop and cannot proceed until the nominated party has inspected and signed off. This is typically used at critical stages where proceeding without verification could result in a defect being concealed.

Witness point: The nominated party is notified and given the opportunity to attend and observe. Work may proceed if the party does not attend after reasonable notice.

Review point: Documentation such as test results, material certificates or photographs is submitted for review. Physical attendance is not required.

Why ITPs matter for builders

For builders and head contractors, an ITP provides documented evidence that the subcontractor's work was executed in accordance with the engineer's specification. This is important for several reasons.

First, it supports the builder's contractual obligation to deliver compliant work. Second, it provides a defence against future defect claims by demonstrating that proper processes were followed. Third, it facilitates project close-out by providing the engineer with the records needed to approve the completed works.

Without an ITP, the builder carries additional risk. If a repair fails months or years later, there is no documented evidence of what was done, what materials were used, or whether each stage was properly inspected.

How CARE approaches ITP documentation

CARE delivers ITP documentation as a standard part of every concrete repair project. Our in-house quality assurance system captures inspection records, material conformance data, and photographic evidence at each stage of the repair process. The completed ITP is handed to the builder at project close-out, ready for the engineer's review and the project file.

This is not an optional extra. It is a fundamental part of how we work. Reliable documentation supports confidence in the completed work and contributes to an orderly, well-documented project close-out.
