Ph: 832 865 4757 <br />Components and Cladding Roof Zones: <br />The Components and Cladding Roof Zones shall be determined based on ASCE/SEI7-16 Component and Cladding design. <br />Notes: 1. U-Builder 2.0 Online tool analysis is only for Unirac SM SOLARMOUNT Rail Flush systems <br />and do not include roof capacity check. <br />2. Risk Category II per ASCE 7-16. <br />3. Topographic factor, kzt is 1.0. <br />4. Array Edge Factor ƳE = 1.5 <br />5. Average parapet height is 0.0 ft. <br />6. Wind speeds are LRFD values. <br />7. Attachment spacing(s) apply to a seismic design category E or less. <br />Design Responsibility: <br />The U-Builder 2.0 design software is intended to be used under the responsible charge of a registered design professional where <br />required by the authority having jurisdiction. In all cases, this U-Builder 2.0 software should be used under the direction of a <br />design professional with sufficient structural engineering knowledge and experience to be able to: <br />•Evaluate whether the U-Builder 2.0 Software is applicable to the project, and <br />•Understand and determine the appropriate values for all input parameters of the U-Builder 2.0 software. <br />This letter certifies that the Unirac SM SOLARMOUNT Rails Flush, when installed according to the U-Builder 2.0 engineering <br />report and the manufacturer specifications are in compliance with the above codes and loading criteria. <br />This certification excludes evaluation of the following components: <br />1) The structure to support the loads imposed on the building by the array; including, but not limited to: strength and <br />deflection of structural framing members, fastening and/or strength of roofing materials, and/or the effects of snow <br />accumulation on the structure. <br />2)The attachment of the SM SOLARMOUNT Rails to the existing structure. <br />3)The capacity of the solar module frame to resist the loads. <br />This requires additional knowledge of the building and is outside the scope of the certification of this racking system. <br />Please feel free to call for any questions or clarifications. <br />Prepared By: <br />Engineering Alliance, Inc <br />Sugar Land, TX <br />Installation Orientation: See SOLARMOUNT Rail Flush Installation Guide. <br />Landscape - PV Panel long dimension is parallel to ridge/eave line of the roof and the PV panel is <br />mounted on the long side. <br />Portrait - PV Panel short dimension is parallel to ridge/eave line of the roof and the PV panel is <br />mounted on the short side. <br />DATE SIGNED: 20-JUL-2023 <br />EXPIRES: :30-JUN-2024 <br />1644 W <br />Ave08/31/23
