On site, things don’t always go to plan. A slab gets poured thinner than specified, a batch of reinforcement doesn’t match the approved drawing, or a supplier delivers material that fails a compliance check. When work, materials, or a process fall short of what was specified, someone needs to formally record it, get it reviewed, and track it through to resolution. That’s the job of a Non-Conformance Report, better known on most projects simply as an NCR.
What is an NCR?
An NCR (Non-Conformance Report, sometimes called a Non-Conformance Record) is a formal document raised whenever work, materials, or a process fail to meet a project’s specified requirements, whether that’s a design drawing, a technical specification, an approved ITP, or a relevant standard. It records what went wrong, why it happened, what’s being done to fix it, and who signed off on the resolution.
NCRs sit within a project’s broader quality management system but are also often referenced in Audits. On projects following ISO 9001 or a similar quality standard, a documented non-conformance process is usually a contractual requirement, not just good practice.
Why NCRs matter in construction
- Traceability: every non-conformance is captured with a clear record of what happened, when, and how it was resolved, rather than living in someone’s memory or a side conversation.
- Accountability: raising and closing an NCR gives clear ownership of the issue, the corrective action, and the sign-off.
- Compliance: many contracts and quality standards, including ISO 9001, require a formal, auditable non-conformance process.
- Cost control: catching and formally addressing a non-conformance early avoids more expensive rework later, especially once work is covered up or built over.
- Client confidence: a clean, complete NCR register at handover shows a client that quality issues were managed properly rather than hidden.
What an NCR typically includes
- Description of the non-conformance: what was found, where, and against which requirement it fails, such as a drawing, specification, ITP item, or standard.
- Root cause: why the non-conformance occurred, not just what the symptom was.
- Proposed corrective action: rework, repair, concession (accepted as-is with justification), or reject and replace.
- Responsible party: who owns the fix and by when.
- Disposition and approval: who reviewed and approved the proposed resolution.
- Close-out evidence: photos, test results, or other proof the corrective action was actually carried out.
Common challenges
- NCRs raised late, or not raised at all, because the issue gets fixed on the fly without a formal record.
- Non-conformances tracked in disconnected spreadsheets or email threads instead of one central register.
- No clear link back to the specific Lot, ITP item, or drawing the non-conformance relates to, which makes traceability difficult later.
- Root cause skipped in favour of just fixing the immediate symptom, so the same issue recurs elsewhere on the project.
- Close-out evidence missing or incomplete at handover, which becomes a problem during a client or third-party audit.
Best practices
- Raise the NCR as soon as the non-conformance is identified, rather than waiting until it’s convenient.
- Link every NCR back to the specific Lot, ITP item, or drawing it relates to, so it’s traceable in context.
- Assign clear ownership and a due date for the corrective action.
- Record the root cause, not just the symptom, so recurring issues can actually be addressed.
- Require photographic or documentary evidence before an NCR is closed out.
- Keep one live register rather than running parallel logs across teams or subcontractors.
How Glaass Supports NCRs
Glaass handles Nonconformity Reports as part of its Quality module, alongside ITPs, Lot Management, and Defect Management. Non Conformances are also used in Glaass’s Audit module. With Glaass, project teams can:
- Raise a Nonconformity Report directly from a Lot or ITP item, so it’s linked to the exact activity and drawing it relates to
- Disseminate the NCR to all relevant stakeholders automatically as it moves through each section
- Track every change on a timestamped timeline, capturing who made each update and when
- Route NCRs through a configurable, multi-step approval workflow via the Workflow module
- Pin an NCR to the relevant 3D model element for teams working with BIM
- Search, filter, and export the NCR register, or export it together with the rest of a Lot’s cases in a Lot Binder
- Raise and view NCRs offline on-site through the mobile app, with automatic sync once back online
By replacing scattered emails and spreadsheets with one connected record, Glaass helps project teams close out non-conformances with clarity, accountability, and full traceability.
Final thoughts
An NCR is only as useful as the process behind it. Raised promptly, linked to the right activity, and closed out with real evidence, it becomes a genuine record of how quality issues were managed on a project rather than a box-ticking exercise. If your team is still managing non-conformances across spreadsheets and email, it’s worth seeing how Glaass keeps NCRs connected to the work they relate to, from first report to close-out.

FAQ
What does NCR stand for in construction?
NCR stands for Non-Conformance Report, also called a Non-Conformance Record. It’s a formal record raised when work, materials, or a process don’t meet the project’s specified requirements.
What’s the difference between an NCR and a defect?
The two terms overlap and definitions vary by project, but an NCR generally covers a broader failure against a specification, drawing, ITP, or standard, which can include materials, design, or process issues, while a defect more often refers to a workmanship or finish issue identified during inspection. Check your project’s quality management plan for the exact definitions it uses.
Who is responsible for raising an NCR?
This varies by project procedure, but it’s typically a site engineer, supervisor, or quality manager who identifies the non-conformance, and many quality management plans allow any team member to raise one.
How is an NCR closed out?
An NCR is closed once the proposed corrective action has been carried out, verified, and supported by evidence such as photos or test results, and the relevant approver has signed off.
Do NCRs need to be shared with the client?
Often, yes. Many construction contracts and quality management plans require an auditable NCR register that’s available to the client or their representative, particularly on projects following ISO 9001 or a similar standard.
