"I'he putp�se of this <br /> inspection was to make a structural evaluation of the existing fnundation and detecmine <br /> its suitability for supportin�a second;loor. Oc.,r investigatzcn was limited solely to the <br /> evaluation of the existing foundation and did not inva]ve any structual analysis of the <br /> proposed additions. <br /> The existing basement is a ful] basement under the remaining existing house. There w-as a <br /> porch and garage structwe that has been remo�-ed as p•rrt of the proposed additioi� and <br /> remodel:ng project. The origina] house wa�constructed in the 194+J's. Th,e foundation <br /> consists of an �" concrete block walI supported on a 4 '.% "x 20" footing. The qu�stion <br /> has been raised as to whetlier or not this is sufiicient ta suppon and additiunal floor as <br /> proposed. <br /> 8" Black Vl�alls <br /> The existing bl,ek walls are in fair to �ood aulicturaE eondition. There is no evidence Qf <br /> settlement or signiticant movement. There� is a vertical cracK on tne northwest corner of <br /> the found�tion. This crack varies in width fro�n a hairline at the base to about 1�'8"at the <br /> mid haight. (See Picture#2 j This crack is a shrinl:a��crack and is not a structural <br /> concern. Masonry shrinks as it ages, espe�;iat;�� the first ye�•or two of;ts fife. It t;-hen <br /> de��elops vertical cracks in random!ocations_ �Lhe��ail s�ans from The fi�oting up to ti-�e <br /> first floor, so the verticai crack does not affect the strucniral strength of the wal[ 'i nis <br /> crack has been there for a ver�� lon};time and shoul�n�t get anv.��orse, even with the <br /> additional load from the new addition. <br /> There is a horizontal crack on the �ast side of'the south walL This crack;s causad bv a <br /> slight bowinb inward of the wall at this location. The crack is of ihe hairline variet}�. [n • <br /> mv opinion the bow in ;he wall is well wrthin acceptable limits. Additional load fr�m the <br /> , new addi[ion ��•ill actually impr��e this condirion and tend to close the crack. <br />
