In progress reports, what should the special inspector describe?

The correct choice emphasizes the importance of detailing the specific inspections and tests conducted during the construction process, as well as the specific locations of these activities, while also assessing whether the work meets the established requirements. This approach ensures that all critical aspects of the quality assurance process are documented. It allows stakeholders to track compliance with design specifications and applicable standards while providing a clear picture of the project's progress.

In contrast to the other options, this choice aligns with the primary responsibility of a special inspector, which includes not only conducting inspections but also reporting on their findings related to quality and compliance. Comprehensive documentation of inspections and test results helps in identifying potential issues early, ensuring that corrective actions can be taken if the work does not meet the necessary criteria.
