What is the maximum load-bearing soil capacity specified for sandy soil classifications?

• A. 1000 PSF
• B. 2000 PSF
• C. 3000 PSF
• D. 4000 PSF

Answer: (B)

Sandy soil classifications typically have a maximum load-bearing capacity that can vary based on factors like moisture content, compaction, and specific soil characteristics. For sandy soils, the commonly accepted values can range from approximately 2000 pounds per square foot (PSF), making this classification an appropriate choice for determining foundational support. This value is based on the inherent properties of sandy soils, which generally exhibit good drainage and can provide adequate support for structures, assuming proper site preparation and grading are performed. Sandy soils can also respond favorably to additional compaction efforts, enhancing their load-bearing capacity further, but the baseline for safe structural design points to around 2000 PSF for typical sandy soil classifications. The other options suggest higher capacities that may not be realistic across all sandy soil conditions without additional engineering treatments or considerations.
