What Is a Non-Conformance Report (NCR) in Construction?
A Non-Conformance Report (NCR) is a formal record that work, materials or documents do not meet the specification, drawings or contract requirements. It identifies the issue, the responsible party and the required corrective action, and stays open until the fix has been verified and the report closed.
When is an NCR raised?
An NCR is raised when an inspection, test or review finds something that does not conform and a simple correction on the spot is not enough. Examples are concrete below the specified strength, wrong material delivered, or work built differently from the approved drawings. Minor items are often handled on a snag list instead; an NCR is used for more significant issues.
What an NCR contains
Contract forms differ, but a typical NCR records:
- A reference number, date and project location.
- A description of the non-conformance and the requirement it breaches.
- Severity, such as minor, major or critical.
- The responsible company and the response or corrective action due date.
- Evidence such as photos and references to inspections or specifications.
NCR lifecycle
The NCR is issued to the responsible party, who acknowledges it, proposes and carries out corrective action, and often addresses the root cause. The issuer then verifies the fix and closes the NCR. Tracking overdue and critical NCRs matters because open ones can hold up acceptance, payment and handover.
NCRs on Gulf projects
Gulf contracts and project quality plans normally define how NCRs are raised, who may issue them, response times and the categories used. Follow the project's quality procedure and forms; the same defect can be an NCR on one project and a snag item on another depending on that procedure.
How Arkan handles NCRs
The NCR module manages the full lifecycle from creation to closure for the selected project.
- Create NCRs with category, severity (Minor, Major, Critical), responsible company, attachments and optional BOQ links.
- Lifecycle actions: Issue, Acknowledge, Verify and Close, or Void, with configurable approval workflows.
- A dashboard shows KPI cards, trends and alerts for overdue and critical NCRs.
- Place Smart Pins on drawings, print an individual NCR report and export the list to Excel.
