<br /> <br />Results: <br />From the evaluation, it was determined that the Existing Roof 1 is subjected to the max. roof load of <br />2.28 psf due to the installation of PV Solar Panels and Mechanical Anchor. <br /> <br />The total system weight per PanelClaw design (68206 lb) to the Roof 1 is less than the max. allowable load <br />(104813 lb) of Roof 1 (See the attached Roof Analysis Report). <br /> <br /> <br />Note: <br /> <br />The original roof is designed for a live load of 20 psf. The design live load shall be replaced with proposed <br />solar panels since people cannot walk on top of panels. The proposed load shall be the PV system load of <br />2.28 psf plus a 5 psf minimum live load for a total of 7.28 psf total load in lieu of the design live load of 20 psf <br />to Roof 1. Therefore, the existing roofs are found to be structurally adequate to carry the proposed PV <br />system. <br /> <br />Assumptions: <br /> <br />The following assumptions were made in the creation of this letter: <br /> <br />1. This report is based solely on the information supplied to us as listed in the “Design Information” section <br />of this report, and the results, in turn, are only as accurate as the data extracted from this information. <br /> <br />2. The existing structures and associated components, including any existing modifications to them, have <br />been installed by original design drawings and are in satisfactory condition to carry their full design <br />capacity. <br /> <br />3. Any existing modifications not listed in the “Design Information” section of this letter have not been <br />considered in the letter. <br /> <br />4. The structural letter is based on that all materials are in good condition and all members are in place <br />and intact. If you are aware of any information that is contrary to that which is contained in this report <br />and analysis, or if you are aware of any defects arising from the original design, material, fabrication, <br />or erection, you should disregard this letter and contact the engineers at Structurology, Inc. <br /> <br />5. This report is considered void if any of the listed information or assumptions stated herein is inaccurate. <br /> <br /> <br /> <br />5 <br />B
