How should nonconforming materials be dispositioned and who approves it?

• A. Immediately recycle without approval.
• B. Rework without quarantine.
• C. Segregate, quarantine, rework, or reject per contract; disposition approved by QA/Resident Engineer or as defined in NCR.
• D. Use them after a retest on site.

Answer: (C)

Nonconforming materials must be handled through a formal disposition process with proper approval. They should be segregated and quarantined to prevent use while a decision is made, then dispositioned as rework, repair, reclassification, or rejection in accordance with the contract. The approval for this disposition comes from the quality authority on site—typically QA or the Resident Engineer—or as defined in the Nonconformance Report. This ensures there’s traceable, contract-aligned control over what happens to nonconforming materials. Why the other options don’t fit: recycling without approval bypasses the formal process and could introduce nonconforming material into the project. Reworking without quarantine skips essential controls and could reuse compromised material. Using them after a retest on site doesn’t automatically authorize disposition—formal approval is still required, per the NCR and contract.
