SSPC Guide for Planning Coatings Inspection
Introduction Inspection is a key component in job quality monitoring. Proper inspection and testing and recording tells the story of what happened at the job site: documenting when the work was done, where it was done on the structure, when it was inconformance with requirements, and when it was out of spec. Without good inspection data, all parties are hard-pressed to figure out what was done and the quality monitoring process collapses. Like any vital process, good inspection doesn’t just happen. It requires planning. You cannot show up at the job site and figure it out as you go. This does not mean that initial inspection plans cannot change as aresult of unknown conditions at the job site or changes in contract requirements (change orders) but without a clear plan going in, there’s little chance the inspection will accomplish its intended goal of telling the project story in the finest detail. A well-thought-out inspection and test plan greatly increases the likelihood that key inspections and tests are done and properly recorded. Thisguide is intended to assist coating and lining inspection companies, contractor quality control personnel, and owners in developing a key tool to ensure that coating and lining inspection is the best it can be. This tool will provide the contractor with guidance on how to plan to do comprehensive QC which will provide a record of objective evidence that it has met contract requirements. It alsohelps the contractor to track progress of the job and to support payment of invoices for conforming work done. Good inspection reports give the facility owner confidence that quality assurance functions (e.g., procedural conformity surveillance; auditing) can be performed with the best available information. Complete inspection reports will support both the contractor and the owner in claims for extrapayment, warranties both implied and express, and latent defects later. Good inspection practice greatly reduces the risk of premature coating failure. When failure does occur, good inspection data will help identify the potential cause. Without such data, hundreds of hours of expensive forensic analysis and destructive testing may be required to identify the cause of the failure. The primaryexamples used in this document focus on inspection of painted steel structures. However, a model that can be readily adapted to inspection of coatings applied to concrete substrates appears in the appendix. As with any model forms, it is important to view them only as examples. A complete analysis of the project job specification is required to develop a good inspection and test plan....
