Hold Points vs Witness Points: Release Protocol for Principals on Civil Projects
Two of the most misunderstood mechanisms in civil construction QA are the Hold Point and the Witness Point. On the surface they look similar — both require the contractor to notify the Principal before proceeding. In practice, the obligations they create are completely different.
Getting this wrong has real consequences. Missing a Hold Point release can mean work proceeds without authorisation. Treating every Witness Point as a formal approval step creates unnecessary administrative load and gives contractors grounds to claim delay.
This article sets out exactly what each mechanism requires — and what happens when things go wrong.
Hold Points: The Full Stop
A Hold Point is a contractual gate. Work cannot proceed past the specified point until the Principal has reviewed the submitted documents and formally authorised the release.
The process:
1. The contractor completes the preceding work
2. The contractor submits the required documents (test results, certificates, method statements, checklists)
3. The Principal reviews the submission
4. The Principal either releases the HP, directs further action, or requests additional information
5. Work may only proceed after release
The submission defines the clock. The review period — typically 5 working days unless specified otherwise in the contract — runs from receipt of a compliant submission. If the contractor submits incomplete or non-conforming documents, the Principal is entitled to return them without starting the review clock. This is a significant point: a submission that does not include all required documentation is not a valid HP submission and does not start the review period.
