What is a nonconformance report in construction?

A nonconformance report, or NCR, is a written record that a piece of work or material does not meet the plans, specifications, or approved submittals, along with what will be done about it.

A nonconformance report (NCR) documents a gap between what was built or delivered and what the contract documents require. It names the problem, where it is, who found it, the requirement it misses, and the fix. Once the fix is verified, the NCR is closed. NCRs are a core tool in quality control programs, and many owners and public agencies require them.

An NCR is not a punch item. Punch lists cover small finish issues near the end. An NCR covers anything that fails a requirement, at any stage, and it often involves an engineer deciding whether the work can stay.

What goes in a nonconformance report

  • NCR number and date, so it can be tracked in a log.
  • Location and scope: gridline, floor, room, or the delivery ticket for material.
  • Requirement violated: the spec section, drawing detail, or approved submittal.
  • Description and photos of the condition as found.
  • Responsible party: the subcontractor or supplier whose work it is.
  • Disposition: remove and replace, repair, use as is, or reject the material.
  • Approval and closeout: who approved the disposition and who verified the fix.

How an NCR works on a real job

Say the GC's quality manager on a three-story medical office walks the second-floor deck before a pour. The anchor bolts for a column are set 1 inch off the layout shown on the structural drawings. The manager writes NCR-014, photographs it, cites the drawing detail, and tags the concrete sub as responsible.

The sub proposes a fix. Because the issue is structural, the engineer of record reviews it and approves a modified base plate rather than tearing out the bolts. That disposition is "repair per engineer's detail." The steel erector fabricates the plate, the special inspector verifies the install, and the NCR is closed with the inspector's sign-off attached. The cost of the plate and the engineer's review is a back charge to the concrete sub, as allowed by its subcontract.

On federal work, the inspection clause in FAR 52.246-12 requires the contractor to maintain an adequate inspection system and to replace or correct work that does not conform to contract requirements. The government may also choose to accept nonconforming work with a price adjustment. A clean NCR log is how a contractor shows that system exists.

Common mistakes and disputes

  1. Treating NCRs as blame letters. Write facts and requirements, not opinions, because the document may end up in a claim file.
  2. Leaving NCRs open. An open NCR at closeout can hold up substantial completion and retainage.
  3. "Use as is" without written approval from the designer. If the field accepts it informally, the contractor owns the risk later.
  4. Fixing the work without recording the cost. Back charges need the NCR, the photos, and the actual cost to stick.
  5. Not trending them. Five NCRs on the same sub in a month is a pattern worth a meeting, not five separate fixes.

Frequently asked questions

Who writes a nonconformance report?

Usually the general contractor's quality manager or superintendent, but owners, inspectors, and construction managers can issue them too. The responsible sub or supplier then proposes the fix.

What does "use as is" mean on an NCR?

It means the work stays in place without correction. It should only be used with written approval from the designer or owner, and sometimes comes with a credit to the owner.

Is an NCR the same as a punch list item?

No. Punch items are minor finish issues found near completion. An NCR records any failure to meet a requirement, at any stage, and often needs engineering review.

Can an NCR lead to a back charge?

Yes, if the subcontract allows it. Keep the NCR, photos, the approved fix, and the actual cost together so the back charge is supported.
