Section 4Testing and Defects

Clause 41.4

Retesting After Defect

Purpose

If a test or inspection shows that any work has a Defect, the Contractor corrects the Defect and the test or inspection is repeated. The cost implications depend on who bears the cost of the repeat test.

Practical Application

When a test identifies non-conforming work, the Contractor must correct it and the same test is repeated to verify compliance. The Contractor bears the cost of correction and the repeat test.

Common Pitfalls

A single defect finding may require multiple successive tests if the correction itself reveals further issues. The Contractor should ensure the root cause is addressed, not just the symptom.
