A 3 ft square footing carries a sustained load of 10 k. It is placed on the surface of a 30 ft thick saturated overconsolidated clay underlain by dense sand. Based on laboratory tests, the clay can be adequately modeled using the e-log-p method. The laboratory tests provide the following compressibility information for the clay:

γ = 123 lb/ft3
Cc/(1+e0) = 0.06
Cr/(1+e0) = 0.002
σ’m = 900 lb/ft2

The groundwater table is located at the ground surface. Compute the settlement of the footing.
