Which of the following is NOT a primary reason for conducting coating surveys?

Determining production quality is not a primary reason for conducting coating surveys because these surveys are typically aimed at assessing the condition and remaining service life of coatings on existing structures rather than evaluating the quality of manufacturing processes.

Coating surveys serve essential purposes like aiding in planning maintenance by identifying areas that need attention before they deteriorate further. They also help with legal compliance by ensuring that striping and operational standards are met, which is critical for maintaining safety regulations. Work prioritization is enhanced through these surveys by highlighting which areas require immediate attention based on their conditions. In contrast, while production quality is important in a manufacturing setting, it is not the focus of coating surveys which are more concerned with the evaluation of the coating's performance in situ.
