I am working on a lab report for a sieve analysis that was conducted in the lab. I got that the soil was made up of approximately: 20.5% gravel, 77.8% sand, and 1.7% fines. The values for the coefficient of uniformity (Cu) and coefficient of gradation (Cc) are 10.56 and 0.528 respectively. What does this mean when it comes to engineering design? Would the soil be considered good for building a structure? If so, is there a specific type of structure that would work best with this type of soil?

Three groups of students from the Geotechnical Engineering class collected soil-aggregate samples for laboratory testing from a recycled aggregate processing plant in Palm Beach County, Florida. Three samples, denoted by Soil A, Soil B, and Soil C, were collected from three locations of the aggregate stockpile, and sieve analyses were conducted (see Figure 2.35).
