ARCHITECTURE <br />April 17, 2018 <br />James Bronder <br />Engineering Public Services Department <br />City of.Everett <br />3200 Cedar Street <br />Everett, WA 98201 <br />Re: Building Permit Review Letter - Structural <br />North Middle School Modernization <br />NAC Project #121-16027 <br />Owner: Everett School District <br />job Address: 2514 Rainier Ave <br />Plan Check No: B1711-003 <br />Dear Mr. Bronder, <br />Below are the Structural plan review comments from your January 2, 2018 letter, along with responses in bold <br />italic text from our structural engineer Coughlin Porter Lundeen. <br />Structural <br />1. It appears there's missing references to Notes 14 and 23 on Sheets 51.01 and 51.02. Please <br />clarify and revise as required. On Note 14, the missinggeneral structural note reference has <br />been added and on Note 23, the missing detail reference has been removed. See updated <br />sheets S1.01 and 51.02. <br />2. On Details 15/54.01 & 17/54.01, it appears that a connection is being called out with a missing <br />reference. Please clarify. A detail reference has been added to these details. See updated <br />detail 15/S4.01 and 17/S4.01 and new detail 14/S4.01. <br />On the permit calculations, it appears that there is masonry. veneer utilized as cladding material, it <br />appears that wind was the governing pressure to design the exterior framing, please confirm that <br />seismic out -plane -loads were computed and that they do not govern the design on the cladding <br />supports, especially where masonry veneeroccurs. Wind is the governing out -of -plane force. See <br />supplementary calculation page SC-1. <br />4. For the lateral force resisting system of the covered play structure, it appears that (1) steel moment <br />frame is provided in each orthogonal direction. In this sense, the "frames appear to be cantilevering <br />off of each other". Please describe the load path to the steel moment frames in each direction of <br />lateral loading. All frames around the perimeter of the covered play structure are steel moment <br />frames so there is a line. of resistance along each side of the rectangular structure. <br />/ >2025 First Avenue, Suite 300, Seattle, WA 98121-3131 <br />206 441 4522 / nacarchitecture.com <br />Seattle / Spokane / Los Angeles <br />
