The water table is at the soil surface. The total unit weight of the soil is 109 lb/ft3, and the unit weight of the concrete is 145 lb/ft3 . Therefore, the undrained shear strength of soil is cu=2000 lb/ft2 . The width of the foundation is 10 ft, and the length is 14 ft, while the foundation base height is 1 ft.
