See comment and response below. <br />Structural Plans Comments: <br />The structural calculations indicate a calculated snow load of 17.6 psf has been used (based on a snow <br />load of 15 psf). While this complies with code, the design must also consider additional snow effects <br />including but not limited to snow drifting, snow shedding from the main building, and ponding <br />effects. Note that the freezer appears to have a flat lid, so ponding during a snow event could be a <br />significant issue. Alternatively, the design may be shown to comply with a uniform load of 25 psf. <br />Response: Attached is sheet U-1-1_3 from the submitted calculations which contains the calculation of <br />the drift snow load of 41.7psf which scales down to the 17.6psf typical roof snow load after 7.5ft. 1 also <br />added an additional calculation with some comparison of the snow drift load vs the 25psf load noted in <br />the comment that would be acceptable to comply with. <br />Please feel free to contact me if you have any questions or comments. Thank you. <br />Sincerely, <br />William H. Thorpe <br />Principal <br />
