Ultimate soil pressure or ultimate pile capacity as shown by tests is normally not used in design, except to establish an allowable soil pressure,q a , or allowable pile capacity. The allowable soil pressure or pile capacity is selected with an appropriate factor of safety, using principles of soil mechanics considering both ultimate load and settlement measured in short-time load tests. Any longtime settlement records available on existing older structures in the vicinity, as well as short-time test data filed with the local Building Authority, are used to establish the safe bearing pressures for various soils specified in statutory local building codes.
