Florida Building Code Practice Exam

A subsurface soil investigation is performed to determine if the ground-water table is above or within what depth below the lowest floor?

1. 2'

2. 3'

3. 5'

4. 7'

The correct answer is: 5'

In the context of building code requirements, understanding the depth of the ground-water table in relation to the lowest floor is crucial for avoiding potential issues such as flooding, structural damage, and the effectiveness of drainage systems. The Florida Building Code emphasizes the need for a thorough subsurface soil investigation to ensure that the water table does not adversely affect the structure. The determination that the investigation must assess the ground-water table at a depth of 5 feet or less from the lowest floor is significant because this depth is commonly associated with the complications of moisture intrusion, which can lead to mold growth, foundation problems, and damage to utilities. By establishing a standard depth of 5 feet for the ground-water table, the code aims to ensure that builders and designers account for the potential impact of ground water on structures, allowing for appropriate site preparation, drainage considerations, and foundation design. This threshold is particularly relevant in locations like Florida, where unique geological and climatic conditions necessitate careful planning to safeguard buildings against water-related issues.
