For a construction project, the ground surface at a building location is lowered 5 ft. A 4-ft square footing (4 ft by 4 ft) imposing a bearing pressure of 4,000 psf is then constructed at the level of the new surface. What net stress increase results in the soil mass 4 ft below the center of the foundation? Assume that the soil unit weight is 120 pcf.
