The piers were driven to <br /> depths of 10 - 11 feet with a minimum installation pressure of 1300 psi. This results in an ultimate axial <br /> capacity of 40868.1 lbs, exceeding the required ultimate load per the design documents. <br /> Summary: <br /> Based on my special inspection and structural observation, the helical piers were installed according to the <br /> engineering design load requirements and according to ESR-4121. <br /> Please give our office a call if you have any questions or need further assistance. <br /> oaNr � Wq, <br /> of WAStricv�y� ' <br /> Regards, �Q�.��C.
