• • • Mr. Paul Pikalov StroyCo Plan Check Number: B2106-003, First Building Review June 16, 2021 General 1. The governing codes should be specified in the construction drawings. See Section R106.1.1. 2. Engineer design may be required for this project per the comments below. If engineered design is performed, the structural drawings and calculations must be sealed and signed by a professional engineer licensed in the state of Washington. See RCW Sections 18.43.010, 18.43.020, and 18.43.070. 3. The project appears to include a lower landing. Additional information on the construction of this landing should be provided. Existing details may be referenced if applicable. See Section R106.1.1. Architectural 1. The deck appears to include a lower landing providing access the backyard. The landing appears to be higher than seven inches above the adjacent grade. Additional steps and a landing are required per Section R311.7. 2. Detail 3/A.2 shows a "minimum"4-inch spacing between balusters and a 4-inch gap between the guard and decking. Openings must limit passage of a 4-inch sphere and should be less than 4 inches. See Section R312.1.3. 3. Continuing with the previous comment, opening limitations should be specified for the stair guards per Section R312.1.3 Exceptions 1 and 2. See additional stair comments below. 4. The Typical Deck Section on Sheet A.2 should specify decay-resistant posts. See Section R317.1.4. Structural 1. The Proposed Plan on Sheet A.1 shows 14-foot joist spans with 2-foot cantilevers. Cantilevers are not permitted for this span per Table R507.6. Alternatively, an engineered design may be performed per Section R301.1.3. 2. The Proposed Plan on Sheet A.1 shows stair framing spanning between cantilevering joist framing. Cantilevers are not permitted to support framing loads as shown. The design should be revised to provide direct support(e.g., posts, etc.). Alternatively, an engineered design may be performed per Section R301.1.3. 3. The Proposed Plan appears to show 4x8 beams supporting the deck joists. The Typical Deck Section on Sheet A.2 specifies 4x12 beams. The following comments should be addressed: a. The required beam size should be confirmed and specified. See Section R106.1.1. b. Deck cantilevers and additional point loads are not permitted on the beams per Structural Comments 1 and 2. Where an engineered design is performed per Section R301.1.3, the beams must also be designed. 3200 Cedar Street 77'N, 425.257.8810 everetteps@everettwagov ) j Everett, WA 98201 425.257.8857 fax everettwa.gov/permits Page20E4
