that the lateral cupacity of the front wall has been improved by a <br /> factor of about 6. <br /> 2. The new 2X6 bearing wall supporting the stairs and second floor can <br /> be 2X6 @ 24" on center assuming the use of either HF#1 or DF#2 <br /> material. <br /> 3. If the present roof structure does not have '/:" cdx plywood over the <br /> existing straight planking, then at the next re-roofing, the old roofing CO�� <br /> material should be removed, the plywood installed over the existing SQ� �,r <br /> planking, and the roofing material placed. The plywood should be ��C� �,�� <br /> nailed with a minimum of 8d nails at 6" on center at all plywood panel �j���� <br /> edges, and 12" on center field. This will bring the allowable roof � � <br /> stress above the 136 plf seen with the additional interior crosswalls. <br /> �1ti_, ���-�,_,./ l���^� ,�i�� <br /> 4. Due to the proximity of the existing building to the west (3 inch s' �;^� <br /> separation, and the ineffectiveness of after-setting any joist to wall tie � f�, <br /> anchors into the existing brick, it is felt that the attempted installation �� � <br /> of seismic wall ties from the existing wood joists to the existing brick � o,��� <br /> walls would be ineffectual to say the least. Consequently, they are �\ <br /> not recommended for installation here. <br /> S.

The general condition of the brick walls appeared to be relatively <br /> good, with few cracks, and the mortar generally in good condition. It <br /> �s felt that major structural repairs to the brickwork are not necessary. <br /> 7. To limit the size of the required hold downs, numerous additional <br /> transfer beams have been added at and slightly below the second <br /> story level. <br /> Structurally speaking, it is felt that the addition uf cross walls alone has <br /> laterally strengthened this old turn of the century structure by at least a factor <br /> of six in the east-west direction. It will be a significantly safer structure after <br /> the clianges than before. Admittedly, it still falls far short of present design <br /> and construction methods, but is it an economically viable way to help <br /> preserve and significantly strengthen a structure that has been nominated for <br /> the National Historic Register. <br /> , <br />
