Instead the mobilized ultimate pile capacity is defined as an applied load at a settlement equal to three percent (3%) the diameter of the pile. The allowable pile capacity is equal to 1/2 the mobilized ultimate pile capacity. The ultimate pile capacity is determined as the ultimate side friction plus two (2) times the mobilized end bearing. It should also be noted that the pile weight is deducted from the total ultimate and failure capacities....
