I have reviewed the attachment plan and have <br /> determined that the roof mounted PV system is in compliance with the applicable sections of the <br /> following Codes as amended and adopted by the jurisdiction: <br /> 2017 Florida Building Code 6th Edition, FBC <br /> ASCE 7 Min. Design Loads for Buildings &Other Structures <br /> Per 2017 FBC,the Roof Mounted PV system will be subject to the following design criteria: <br /> Design Wind Speed(V„it) - 140mph 3sec gust, Exposure Category— B <br /> The PV System consist of the modules, railing, and connection hardware.The system will add a <br /> dead load of approximately 3 psf to the roof. <br /> The existing roof covering is TPO with min. l/a" plywood decking and 2"x 4" roof trusses 24" O.C. <br /> The roofing, decking, and roof trusses are in good condition.The existing structure will be adequate <br /> for supporting the additional PV dead load and wind loads. <br /> The securement method of the PV system is to be flush mounted to the TPO roof with the Ironridge <br /> railing and the RT mini mounts.The attachments can be attached up to 72" apart in roof zone 1,48" <br /> apart in roof zone 2,and no mounts in roof zone 3.The mounts should be staggered,where <br /> possible,to allow distribution of the design loads evenly to the structure.The mounts shall be <br /> installed with 2 x M5 x 60mm stainless lag screws directly to the roof truss. <br /> Please see attached documents and contact me should you have any questions. <br /> Sincerely, <br /> D.
