Consider Figure FE 3. Compute the difference in the primary consolidation settlement. Further, if foundation B is to be loaded with an additional 150 kN, suggest an increase in dimension for said foundation if a differential settlement of 20 mm is not to be exceeded. You may use the equation for primary consolidation settlement of HomvΔσv.
