The wall must be 12 inch block full height to tn�ss bearing at the <br /> back, east and west sides to the extent now existing. It is satisfactory tv remvve block down to <br /> the existing 8x20 footing which is sworn to contain 2 longitudinal bars. Dowel 3 foot lon�No. 4 <br /> bars into footing to coincide with tilled cores. k;ither grout or resin may be used to set#4 bars. <br /> Use running bond, No. 7 vertical bars at 4 feet c-c, 1 inch clear from inside of inside face, fili <br /> cores half height, vibrate, later fill 2°� half, again vibrating. Use top bearing floor trusses. Do no <br /> backfill until both floors in place_ <br /> It will be OK to lea.ve block helow the new fooiin�. Compact soil below both sides before <br /> placing footing. There is to be a bond beam with 2 continuous No. five bars,top course <br /> ln my opinion, the above will be struoturally satisfactory. Please feel free to contact me should <br /> you have ax�y questions. <br /> Very truly yours, <br /> 1 hcrcby a;rtily that this plan,spcciticalion or rcpvrt <br /> was prcparod by mc cx undcr my dircvY supcnision <br /> and that 1 am a July ficcaticd Profcssional t,ngin�tir <br /> underthe Iaws oC[he Staze ofMinnesuia. <br /> W.T.McCallu �G <br /> � � ��� , � <br /> Datc_ KCoisVation Nu. 1U540 <br /> W.
