FA <br /> fi <br /> Ii <br /> rf n M <br /> 411 "so <br /> View inside of the Crawlspace at the Stemwall and Post inside the Southeast Corner <br /> The pipe pier shafts will be supported their full length against buckling. They will be installed in <br /> clayey marine sediment or glacial till soil, typical in the Puget Sound area, which has no acidic <br /> conditions that would deteriorate the steel piers I anticipate that a hard bearing layer is <br /> probably present about 15 to 20 feet below the footings based on installing piers in nearby <br /> properties. <br /> I have calculated that the pressure used to drive the piers should be at ;east 11 500 pounds of <br /> equivalent torque capacity under the rear or east side wall and 8,000 pounds at the south gable <br /> side wall of the home I used a snow loading of 25 psf at the roof and 40 psf live floor loading, <br /> with dead loading consistent with the materials used in construction <br /> In conclusion. I found that the rear or east side of the Smead Family Residence at 2215 <br /> Lombard Avenue in Everett. Washington has experienced up to 31/2-inches of settlement for the <br /> two-story structure Please refer to my attached repair plan for stabilization recommendations <br /> possible with seven hydraulically driven helical piers with foundation brackets placed under the <br /> foundation of the home at this corner. <br /> I have enjoyed working with you on this project If you have any additional questions, <br /> comments, or concerns please feel free to call <br /> 10\ <br /> Pr' <br /> Ti 4t- sA old .E. <br /> 1 EXPIRES 6 i 91 ;,3 ] <br /> �I I� <br />
