Two typical boring logs and a summary of test data at the Dixie College Science Center are attached. Based on the unconfined compression testing, estimate the allowable bearing pressure for square footings with widths from 2 feet to 10 feet. Compute gross and net values assuming the footings are located at a depth of 3 feet. Use the refined technique for computing bearing capacity with N_c=5.14 and shape and depth factors.
