Our analysis was based upon the seismic design criteria <br /> provided by the 2010 California Building Code. It utilizes the tank construction and <br /> anchorage information that you provided. We assumed that the tank was anchored using <br /> 5/8" diameter expansion anchors installed in an 8"thick concrete slab. Based upon the <br /> results of our analysis, we found that the anchorage of the tank to the concrete slab was <br /> adequate to resist the code Ievel seismic design forces and confirm that the anchorage as <br /> constructed is in compliance with the 2010 California Building Code. <br /> If you have any questions,please feel free to give us a call. <br /> ®gROFEssop�,9 <br /> Yours truly, KO <br /> 0.2 99 T�,m <br /> EXP. 12/31/12 <br /> David J.
