How often should special inspection reports be provided to the building official?

Special inspection reports are critical documents that ensure compliance with various construction standards and regulations. The frequency with which these reports must be submitted to the building official is primarily determined by the requirements set by the building official himself. This flexibility acknowledges that different projects have varying complexities, timelines, and phases of inspection needed.

The building official may impose specific reporting timelines based on the unique demands of the project in question. As a result, the most appropriate answer is that reports should be provided as required by the building official, allowing for tailored oversight that aligns with the project's particular needs and schedule.

While reports could be daily, weekly, or tied to project specifications, the governing authority's requirements ultimately take precedence, making option C the best choice in this context.
