GEOLOGIC SETTING <br /> The existing structure is located in Everett,Washington. The geologic structure in the area is comprised of silty loam 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 push piers is 28000 lbs,and based on the geologic setting,we expect the piers to achieve adequate capacity <br /> at approximately 8—25 feet. We recommend that the piers with a 2 7/8 inch shaft and be installed to a minimum depth of 8 feet and a minimum <br /> installation pressure of 5600 psi,or refusal,using a 9.62 square inch hydraulic ram. <br /> Regards, pp � � <br /> 4.2`6( 0,,01 Wq yN <br /> OFWAsi F <br /> Daniel Stark,P.E. <br /> 444: <br /> Q �� '� �'CJ,�� <br /> Stark Foundations Z 1,4\'41 <br /> .
