![Estimate the primary consolidation settlement of the clay in centimeters from a
28,000 kN load on an 8m by 10 m footing. The subsurface consists of a 10 meter
thick layer of sand and gravel overlying a 4 meter thick layer of normally-
consolidated clay (OCR=1). Assume sand and gravel layers do not settle. Below
the soft clay is sand and gravel. Water table is 3 meters deep. Subsurface
