The site for a commercial building project has the surface elevation lowered 2 m to improve area grading for building access, parking, and drainage. Foundations for interior building columns will be constructed at the level of the 340 new ground surface. Each foundation is 1.5 m by 1.5 m square and imposes a bearing pressure of 200 kPa. What net stress increase results in the soil 1.25 m below the center of the foundation? Assume Boussinesq conditions apply and soil unit weight is 18 kN/m3.

The site for a commercial building project has the surface elevation lowered by 1.17 m to improve area grading for the building access, parking and drainage. The unit weight of the soil removed was 19 kN/m3. Foundations for the building will be constructed at the level of the new ground surface elevation.
