Mr. David Schuerman <br /> Plan Check Number: B2307-037, First Building Review <br /> August 15, 2023 <br /> Structural <br /> 1. Guard details should be included in the construction drawings, even if the railing is to be"BY <br /> OTHERS". The guards should comply with IRC Section 312.1. The guards, connections to the <br /> supporting deck framing, and the supporting framing should be designed to resist a minimum <br /> 200-pound load per table R301.5. <br /> 2. On sheet S-2, it appears that only one DTT1Z is to be installed to connect the P.T. joists to the <br /> existing structure. Per figure R507.9.2(2) a 750-pound capacity hold-down device should be <br /> installed at four locations, evenly distributed along the deck and one within 24 inches of each <br /> end of the ledger. Please indicate on the drawings the placement of the DTT1Z's. <br /> 3. It also appears that the 18-inch square footing size is smaller than the minimum size allowed <br /> per table R507.3.1. The footings beneath the posts appear to be different sizes. On sheet S-2 <br /> the footing is 18 inches square but on sheet S-3 the footing is 24 inches square in the brace <br /> detail. Please clarify the footing size and placement. <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 the <br /> laws of the state of Washington. <br /> If you have any questions or require additional clarification, please contact us. <br /> Respectfully, <br /> Cal Bearman, P.E. <br /> Associate Engineer/ Commercial Building Plans Examiner <br /> (425) 257-8813 <br /> cbearman@everettwa.gov <br /> S:\#Common\Bldg Permit Reviews\2_Residential Reviews\5019 Colby Ave_Deck\B2307-037 _5019 Colby <br /> Ave—Building Review Letter 1.docx <br /> 3200 Cedar Street © 425.257.8810 O permitservices@everettwa.gov <br /> Everett,WA 98201 425.257.8857 fax everettwa.gov/permits <br /> Page 2 of 2 <br />
