Coastal and Floodplain Construction Inspector's Practice Exam

How should elevated exterior platforms for utilities be supported according to construction standards?

1. By concrete slabs

2. On piles or columns

3. Directly on the ground

4. By walls and fences

The correct answer is: On piles or columns

Elevated exterior platforms for utilities should be supported on piles or columns to ensure adequate structural stability and safety, especially in coastal and floodplain areas. This method of support helps to elevate the platforms above potential flood levels, mitigating the risk of water damage to critical utility installations. Piles or columns also provide a strong foundation that can withstand lateral forces from wind or flood conditions, ensuring the long-term durability of the utilities housed on these platforms. Utilizing piles or columns is a prevalent standard in construction due to their ability to distribute loads effectively and provide resistance against environmental challenges such as erosion or water movements. This design consideration is crucial in locations prone to flooding, where conventional ground-level support might lead to significant hazards during extreme weather events. Other options, such as concrete slabs or direct ground support, do not offer the same level of protection against floodwaters and may result in damage or failure of utility systems during adverse conditions. While walls and fences may serve as barriers, they do not provide the necessary structural support to elevated platforms.
