Tectonic <br />Engineering Consultants (Tectonic) has reviewed the SM design methodology along <br />with the U-Builder tool; a Unirac online design tool. The review included the <br />following SM products, SM Light, Heavy Duty, and Standard rail with both the <br />standard and pro hardware. <br /> <br />Tectonic has determined that the design is a rational approach and follows the <br />structural requirements of the following reference documents: <br /> <br />Codes/Standards: <br />• 2021 International Building Code by International Code Council. <br />• 2022 California Building Code, Title 24, Part 2 (Volumes 1 & 2). <br />• ASCE/SEI 7-16 Minimum Design Loads for Buildings and Other Structures , by <br />American Society of Civil Engineers with provisions from SEAOC PV-2-2017. <br />• 2020 Aluminum Design Manual, by Aluminum Association. <br />This letter certifies that the structural analysis of the racking members, connections, <br />and components directly related to Unirac’s system are in compliance with the <br />above codes. The design methodology is acceptable under components and <br />cladding loads associated with the building’s roof structure when the system is <br />installed in accordance with manufacturer specifications. If the loading criteria does <br />not meet Unirac’s specifications, owner shall contact Unirac for a site-specific <br />certification. <br /> <br />Attachments approved for the SM system to the structure include the following <br />and is installed per Unirac’s U-Builder report and installation guides: <br />▪ Shingle Roof: L-Foot Flashkit Pro, Standoffs, Flashloc Comp, Flash Loc Duo, <br />and Flash Kit Pro SB <br /> <br /> <br />
