Connect the holdowns to the existing concrete using the attached <br />schedule. <br />The Simpson HHDQI I-SDS2.5 holdowns, located on the ends of the lower level south <br />perimeter shearwalls, must also be connected to the existing concrete per the attached <br />schedule. Verification of the anchor bolt installation must be approved by this office or a <br />testing agency qualified to inspect this type of work <br />Please contact this office with any questions regarding this letter. <br />Sincerely, <br />' t <br />Chris Covington, P.E. <br />CI. , OF EVERelI <br />REVIEWED FOR PERMIT <br />6131) <br />411 <br />�0VIAr T <br />1� F ASfr/,1, O <br />,'!, <br />-off_ <br />�q3 3 <br />310 <br />JAN 0 2011, <br />JUN 03 2009 <br />Structural Design Associates <br />2210Ileaitt Ave, Snile,101, F%erett, WA 98201 ^ <br />11h: 4_25-339.0293 fax: •12S_2i2.0910 tve,c.slrucdes.coin S� <br />
