In a field with a 5.5 m thick clay layer with a top and bottom drained condition, a field preloading test was performed. From the observed settlement curve, 20% consolidation has been achieved in 2.5 months. A nearby site with similar soil has a 7.0 m thick clay layer. Estimate the following: (a) Time for 50% consolidation of 7.0 m thick clay layer (b) Time for 90% consolidation of 7.0 m thick clay layer 9.6
