Several <br />additions and modifications have been made since the original construction, of which there are apparently <br />no records as to the date or extent of the modifications. A large percentage of the construction appears <br />to have been accomplished prior to the advent of any building code. Recently the building was damaged <br />by fire, to such an extent that major repairs are required to restore its previous functionality. <br />Based on our interpretation of Chapter 34 of the 2006 IBC, we believe there are essentially two <br />resMctions to meet. The first requires that repairs meet tlie curcent code if loads on any existing member <br />are increased by more than 5°h. The second required that existing members may not b� reduced in <br />strength by more than 5%, unless engineering calculations indicate that these members are adequate to <br />support the imposed loads. Else new, code-compliant members must be installed. Our approach has <br />been to address both these requirements and the other requirements of Chapter 34 in as cost�ffective <br />ma�ner as practical. <br />The following cornprises our report: <br />Observations: <br />Roof Su000rt: The bearing wall which was removed was located in the middle of what now appears to be <br />a living room. This wall is assumed to have supported the roof haming prior to its removal. However <br />there appears to be no new deflection of the ceiling since removal of the wall, and observation of the roof <br />framing directly above the wall reveals almost no framing that would have been bearing on the wall. <br />Page 1 of 3 � <br />�.� <br />
