The site for a commercial building project has the surface
elevation lowered by 1.41 m to improve area grading for the
building access, parking and drainage. The unit weight of the soil
removed was 19.0 kN/m3. Foundations for the building will be
constructed at the level of the new ground surface elevation. Each
foundation is 1.5 m by 1.5 m square and imposes a bearing pressure
of 314 kPa. Using the 2:1 approximation method determine the net
increase in stress (kPa) at a depth of 1.0 m below the footing.
