IIRReir1 <br />CONSULTING ENGINEERS <br />wall. Note that the capacity of the load path from the new wall through the first floor and basement <br />bearing lines to the foundation would first need to be determined. Preliminary observations indicate <br />that the existing bearing line is suitable to support this new cripple wall, although selective <br />strengthening of the Basement level header beams should be expected. <br />3. Support the rafters at mid -span with diagonal web members or sister the rafters with engineered <br />lumber. <br />4. Until repairs are performed, potential failures of portions of the roof framing could occur if overloaded <br />by snow or wind pressure. It is therefore recommended that the roof framing be temporarily shored or <br />that roof strengthening repairs be performed as soon as possible. Snow exceeding 4 inches in depth <br />should immediately be removed from the roof. Snow removal should be performed from ladders or a <br />lift so that workers are not on the roof concurrently with snow. <br />Further development of repair solutions is necessary to reliably estimate repair costs and those costs <br />should be estimated by a contractor experienced with this kind of work. <br />Similar repairs should also be considered over the Porch, since those rafters are also not compliant with <br />Code. <br />Over the two smaller west portions of the house, the roof framing appears to be functioning well without <br />any signs of distress or deterioration. No repairs appear to be necessary although a more thorough <br />investigation may reveal other deficiencies. <br />Respectfully, <br />JVA, INCORPORATED <br />By <br />Ian R Glaser, PE <br />Senior Project Engineer <br />Photogra • hs: <br />Reviewed By <br />Daniel E.
