The settlement analysis for a proposed structure indicates that 6.5 cm of settlement will occur in 3.4 years and that the ultimate total settlement will be about 22 cm. The analysis is based on the assumption that the compressible clay layer is drained at both its top and bottom surfaces. The owner decides to build a duplicate of the first structure nearby. During foundation investigations, it is discovered that the clay layer under the new building would be about 25% thicker than under the first structure. Otherwise, the properties of the clay are the same. Estimate for the new structure the ultimate total settlement (in cm.). Explain your answer.
