This Da Nang public-building case follows material traceability from technical approval to installation, including submittals, incoming inspection, witnessing and nonconformity management.
Submittal stage
Check specifications, installation locations, technical documents and sample requirements. Proposed substitutes must identify differences and application limits; a similar product name is insufficient for approval.
Incoming inspection
- Verify batches, quantities, appearance, labels and accompanying documents.
- Plan sampling, witnessing or third-party testing and link results to the relevant work area.
- Separate and label materials awaiting inspection and accepted materials to prevent unintended use.
Issue resolution
Record segregation, assessment, return or conditional acceptance. The assigned party verifies corrections; the register retains the original issue, decision basis and final status.
The process is a reference for organising records. Test parameters and acceptance criteria follow the design, contract and local regulations.
