GEOLOGIC SETTING <br /> The existing structure is located in Zephyhills, Florida. The geologic structure in the area is comprised of loamy sand and the site is gently sloping. <br /> It is our opinion that the localized settlement is a result of improper foundation drainage and/or undersized footings. We believe'that suitable <br /> . - support can be achieved by installing helical and/or push piers. <br /> SUMMARY. <br /> The ultimate load requirement for the helical piers is 12000 Ibs and based on the geologic setting,we expect the piers to achieve adequate <br /> capacity at approximately 8—25 feet. We recommend that the piers with a 2 7/8 inch shaft and 10 inch diameter helix plate be installed to a <br /> minimum depth of 8 feet and a minimum installation torque of 1400 ft—Ibs,or refusal. <br /> Regards, <br /> p D w ,�,.��`�pN1EL Wq <br /> Daniel Stark,--P.E.
