Florida Building Code Practice Exam

The correct answer highlights that the building foundation inspection is conducted after multiple critical components of the foundation preparation are completed. This includes not only the excavation of trenches but also the incorporation of various foundational supports such as stem-walls, monolithic slab-on-grade, piling/pile caps, and footers/grade beams.

The rationale for timing the inspection at this stage is to ensure that all structural elements are correctly in place before concrete is poured or further construction progresses. Each of these components plays a vital role in the overall integrity of the building's foundation. By inspecting after these steps, it allows the inspector to verify that the foundation meets the required specifications and codes before any potentially obstructive activities occur.

This timing also aligns with standard construction practices and safety protocols outlined in the Florida Building Code, confirming that the foundational preparation has been adequately performed to support the building structure.
