Focusing on "Choosing the Right Thickness: A Guide to Load-Bearing Plywood.", this article breaks it down one by one from the four levels of design basis, material matching, construction control and acceptance evidence, and provides parameters, practices and checklists that can be directly implemented for the design, procurement, construction and supervision teams to compare and implement.

1. Documents to be prepared during the bidding stage

Technical standards should include product standards, system test reports, environmental testing, certificates and quality assurance commitments. Documents must correspond to each other: the model, thickness, and structure in the report must be consistent with the bid product, otherwise it may be invalid during the review.

2. Report effectiveness and coverage

3. On-site acceptance and random inspection

When materials enter the site, check the brand, model, batch, thickness and appearance, conduct random inspections on a proportional basis and send them to a third party for re-inspection. If any inconsistency with the sealed sample is found, isolate it immediately and do not use it first and then add information later.

4. Data archiving

• Establish a material ledger to record entry time, batch and used parts.
• Save the original test report and inquiry records.
• Concealed project acceptance records and photos are archived simultaneously.
• Resubmit the changed materials for testing and approval.

The significance of standards and certification is traceability. Only when documents, samples, and construction are consistent can the project successfully pass review, acceptance, and post-audit.
