A settlement analysis carried out for a proposed structure indicates that 9cm of settlement will occur in 5 years and the final settlement will be 45 cm based on doubled drainage condition. A detailed site investigation indicates that only single drainage exists. Estimate the settlement at the end of 5 years for the changed condition. Use T, = (t/4)U². %3D
