Quality concepts
Nonconformance
A nonconformance is work that fails to meet a stated requirement: the drawing, the specification, the approved submittal or the acceptance criteria. It is more than a note to fix later. Once identified it gets logged, usually on a nonconformance report, and carried through to a disposition: use-as-is, repair, rework or reject. Naming it a nonconformance is what forces a decision on the record instead of a quiet field patch.

Why it matters
Unlogged nonconformances are how a job accumulates hidden risk: the substitution nobody approved, the slab that came in low, the assembly that no longer matches the fire-rated detail. Tracking them means someone with authority decides what happens and why, and the decision is documented.
It also protects the builder. A closed nonconformance with photos and a signed disposition is the difference between a defensible record and a warranty argument two years later.
How it shows up on site
A failed checklist item or a rejected inspection becomes an NCR entry. The item is photographed, described against the requirement it missed, assigned a disposition, and not closed until the corrective work is verified.
Guides that use it
- How to document inspections with photosMake inspection photos that actually prove something: shoot the concealed condition before cover, tag location and date, and tie each shot to the checklist item it backs.
- How to manage a nonconformanceTake a nonconformance from discovery through documentation, disposition, corrective action, and re-inspection so it closes with evidence, not memory.
- How to do root cause analysis on a defectTrace a recurring defect past the symptom to the cause that let it happen, then put a corrective action in place that keeps it from coming back.
- How to inspect work a subcontractor turns overInspect a subcontractor's completed work before you accept it: verify it against the contract scope and specs, document defects, and make acceptance conditional on the fix.

Related terms
- Nonconformance report (NCR)A formal record raised when installed work does not meet the drawings, specs or an accepted standard, and the plan to resolve it.
- Corrective actionThe step taken to fix a nonconformance and stop it happening again: both the repair and the change that prevents a repeat.
- DeficiencyWork that is incomplete, missing or not up to standard: the catch-all a punch list and inspections use for anything that still needs attention.
- DefectA flaw in materials or workmanship that makes the work fall short of what was specified or of accepted trade practice.
- Root cause analysisWorking back from a defect to the real reason it happened, so the fix stops it recurring instead of just cleaning it up once.
- Re-inspectionA repeat of an inspection after a failed result, run once the flagged work has been corrected and is ready to be checked again.
Knowing the term is step one. Proving it is the job.
RTI holds the submit button until every mandatory item is answered and the photos are attached, then chains the record so it can be proven untouched later.
