Problem: An industrial building is to be supported on a series of 14" square prestressed concrete piles which will be derived 45' into the soil profile below. The groundwater table is at a depth of 15' and all of the strata may be assumed to be normally consolidated. These piles have been designed without the benefit of any onsite static load tests, dynamic tests or indicator piles, but a wave equation analysis has been performed. Using the Dennis and Olson method, compute the allowable downward and upward load capacitates of each pile.
