N8Minimum requirements for shop- or field-applied coatings

When coating or touch up is specified in the contract documents to be performed by the fabricator or erector, the fabricator or erector, as applicable, shall establish, maintain, and implement QC procedures to ensure the proper application of coatings on structural steel in accordance with the coating manufacturer’s product data sheet.

User Note: When there is a conflict between the coating manufacturer’s product data sheet and the contract documents for the proper application of a coating, it is recommended to clarify with the engineer of record which will govern.

Unless there is direction to the contrary in the contract documents, observation of the coating process prior to, during, and after the application of the coating shall be the primary method to confirm that the coating material, procedures, and workmanship are in conformance with the construction documents.
