Quality concepts
Defect
A defect is a fault in the work itself: a flaw in the material or the workmanship that leaves the finished product below the specification or below accepted trade standards. It differs from a plain deficiency in emphasis: a defect points at something built wrong (a honeycombed pour, a cold solder joint, a delaminating finish), where a deficiency can just be work that is unfinished. Defects are what warranty claims and latent-defect disputes are made of, so how they are found and recorded matters.

Why it matters
A defect caught at inspection is a repair; the same defect found after occupancy is a claim. The value of a good QC record is that it either catches the defect before cover-up or proves the work was sound when it was inspected.
Some defects are patent (visible on a walk) and some are latent, hidden until the assembly is loaded, wetted or aged. Concealed-work photos are often the only evidence of what a latent defect was hiding behind.
How it shows up on site
A failed inspection item that traces to bad material or bad installation, not just missing work. It gets written up, photographed, and where it breaks a requirement, carried as a nonconformance with a disposition.
Guides that use it
- 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 write a daily construction reportWrite a daily construction report that reconstructs the day accurately (crews, work, weather, deliveries and issues) so it carries weight when a delay or dispute is argued.
- How to photograph construction defectsPhotograph a defect so the picture proves what, where and how big, with context, scale and a location tie that survives being questioned months later.

Related terms
- 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.
- NonconformanceInstalled work that does not meet the drawings, spec or accepted submittal, formally identified so it gets dispositioned, not ignored.
- ReworkTearing out and redoing work that failed inspection so it meets the spec: the costly disposition everyone is trying to avoid.
- 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.
- Quality control (QC)The hands-on inspection and testing of installed work against the spec: checking the actual product, not the process that made it.
- ToleranceThe allowable amount a dimension or condition can vary from the target and still be acceptable: the plus-or-minus on a spec.
Knowing the term is step one. Proving it is the job.
