Mr. Harold Christensen <br />Lance Mueller & Associates <br />Plan Check Number: B2301-011, First Building Review <br />February 3, 2023 <br />Lateral System: <br />2. Elevations 1/S3.1 and 4/S3.1 specify W18x65 braces and reference Detail 6/S3.1 for the <br />connection. The brace size appears to be incorrect and should be revised. Alternatively, a <br />detail representing this configuration should be included. Revised calculations may be required. <br />See IBC Sections 107.2.1, 1603.1, 1604.1, and 1604.4. <br />3. Calculations substantiating the design of the braced frame connections should be submitted for <br />review. The design should comply with AISC 341-16 Section F2.6a. See IBC Sections 1604.1 <br />and 2205.2. <br />4. Continuing with the previous comment, it is noted that the vertical weld in Detail 2/S4.2 is <br />located on the back of the column only. This configuration should be considered in the <br />calculations as it will impact the magnitude and type of stresses induced in the welds and <br />connection plates. See IBC Sections 1604.1 and 1604.2. <br />5. The bracing connections in Details 5/S3.1 and 2/S4.2 appears to be missing weld requirements <br />and should be revised. See IBC Sections 107.2.1 and 1603.1. <br />6. The column design does not appear to include overstrength per AISC 341-16 Section D1.4a. <br />Supplemental calculations substantiating the deign should be submitted for review. See IBC <br />Sections 1604.1 and 2205.2. <br />7. Calculations substantiating the design of the column anchorage should be submitted for review. <br />The column bases should comply with the loading requirements of AISC 341-16 Section D2.6. <br />The anchors should comply with the loading requirements of ACI 318-14 Section 17.2.3.4.3. <br />See IBC Sections 1604.1, 1901.2, and 2205.2. <br />This review has been performed for general compliance with the building codes as adopted and <br />amended by the state of Washington and the city of Everett. Corrections and comments made <br />during the review process do not relieve the project from compliance with code and permit <br />requirements. The designers -of -record are responsible for a complete design in accordance with <br />the laws of the state of Washington. <br />If you have any questions or require additional clarification, please contact us. <br />Respectfully, <br />Drew Martin, P.E., S.E. <br />Associate Engineer / Commercial Plans Examiner <br />(425)257-8813 <br />dmartin@everettwa.gov <br />S:\BMartin\2023\B2301-011—Rl.docx <br />IOU 3200 Cedar Street © 425.257.8810 C(Q) <br />everetteps@everettwa.gov <br />Everett, WA 98201 425.257.8857 fax everettwa.gov/permits <br />Page 3 of 3 <br />
