A proposed office building will include an 8 ft 6 in square, 3 ft deep spread footing that will sup-port a vertical downward service load of 160 k. The soil below this footing is an overconsolidated clay with the following engineering properties: Cc /(1 + e0) = 0.10, Cr/(1 + e0) = 0.022,sm′ = 4,500 lb/ft2and g = 113 lb/ft3 . This soil strata extends to a great depth and the ground-water table is at a depth of 50 ft below the ground surface. Determine the total settlement of this footing.

Question
A proposed office building will include an 8 ft 6 in square, 3 ft deep spread footing that will sup-
port a vertical downward service load of 160 k. The soil below this footing is an overconsolidated
clay with the following engineering properties: Cc /(1 + e0) = 0.10, Cr/(1 + e0) = 0.022,
sm′ = 4,500 lb/ft
2
and g = 113 lb/ft

. This soil strata extends to a great depth and the ground-
water table is at a depth of 50 ft below the ground surface. Determine the total settlement of this
footing.
