The structure of Problem 9.19 was constructed and performed essentially as expected during the first 3.4 yr (that is, the settlement of the building was about 6.5 cm). 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:
(a) The ultimate total settlement
(b) The settlement in 4.5 yr. (After Taylor, 1948)
