The piers were driven to depths <br /> of 10-15 feet with a minimum installation pressure of 10000 psi. This results in an ultimate axial capacity of <br /> 50000 lbs, exceeding the required ultimate load per the design documents. <br /> Summary: <br /> Based on my special inspection and structural observation, the push piers were installed according to the <br /> engineering design load requirements and according to ESR-3969. <br /> Please give our office a call if you have any questions or need further assistance. <br /> a St W,q y* <br /> Reaards.p �n R�4•/• � Wqs�, ,'�� <br /> Daniel Stark.
