When it comes to quality, people sometimes disagree ... Quality Control and Quality Assurance: Defining the Roles and Responsibilities of the Contractor's QC and the Owner's QA

摘要

Every painting project begins with the expectation that the result will be a painted structure that will be protected for a minimum period of time. Owners rely on tools such as the specifications, contractor certification, quality control, and quality assurance inspection to verify that the work is performed as specified. While many projects require quality control and/or quality assurance inspections, few specifications, if any, differentiate between the two or provide guidance on the responsibilities of each. After discussing the difference between the functions of quality control and quality assurance, this article reviews the SSPC certification program requirements, other recognized industry standards, and transportation specifications that establish minimum standards of practice for quality control and quality assurance. It concludes with recommendations for maximizing the benefits of both quality control and quality assurance.
