The analysis was according to applicable building codes, professional engineering <br />and design experience, opinions and judgments. This evalution produced for this structure's assessment is only <br />for the proposed solar panel installation referenced in the stamped plan set and were made according to <br />generally recognized structural analysis standards and procedures. Prior to commencement of work, the <br />contractor shall verify the framing sizes, spacings, and spans. Contractor shall also verify that there is framing <br />damage or deficiencies. If observed, the EOR must be notified before install. <br />The increase in seismic Dead weight as a result of the solar system is less than 10% of the existing structure <br />and therefore no further seismic analysis is required. <br />projects@evengineersnet.com <br />http://www.evengineersnet.com
