Rod Koon 5003 Ocean Ave, Everett, WA 98203 Plan Check Number: B2112-017, First Building Review March 22, 2022 Structural 1. Plans should specify all design load values, including dead, live, and snow. 2. Submittal documents included calculations for only the retaining walls and the lateral design were submitted. The framing appears to not comply with the prescriptive limitations of the IRC. An engineered analysis and design should be performed per IRC Section R301.1.3; sealed and signed drawings and calculations prepared by a professional engineer licensed in the state of Washington are required per RCW 18.43.010, 18.43.020, and 18.43.070. The framing and foundation plans, and structural calculations as required, should show a complete load path. Provide framing and foundation details of construction. See IRC Section R301.1. 3. See the notes on Sheets 5 and 6 specifying floor joist supplier and truss manufacturer to provide detailed plan and engineering for floor and roof systems. Floor joists are specified on the plans to be 11 7/8 TJI 110 @ 16" o.c. or alternate engineered system. Engineered calculations should be provided for all framing members. If engineered floor trusses are to be used, a statement of deferred submittals should be included on the plans listing work designated as deferred submittals (pre -manufactured roof and floor trusses). The note should include a statement requiring the engineer -of -record to review the deferred submittals and verify conformance with the construction documents. See IBC Sections 107.2.1, 107.3.4, 107.3.4.1, and 107.4. 4. Continuing with the previous comment, details of the roof and floor framing should be included. Note that these details are the responsibility of the engineer -of -record and not the manufacturer. 5. See Sheet 5. The framing at the stairs is unclear. Please provide framing information and supports as required to show a complete load path. 6. See garage wall on Foundation Plan on Sheet 4 and Section A on Sheet 5. It appears that the detail for cantilevered retaining walls is specified on the Foundation Plan. The detail shows a slab at the bottom of the wall, but no slab is present at the adjacent crawl space. Provide a new detail and calculations substantiating the design. Section A on Sheet 5 shows no retaining wall at the garage wall. Drawings, details, and detail references should be updated to match. 7. Continuing with the previous comment, Section A on Sheet 5 shows a retaining wall about 8 feet away from the garage footing. Footings should be situated to where no surcharge load occurs to the walls of the lower foundation. A minimum depth of the garage wall footing should be specified on the plans, so no surcharge occurs. 8. See retaining wall calculations and retaining wall details. Address the following: a. The seismic load 7h is not applied to the cantilevered retaining walls. Retaining walls supporting more than 6 feet of backfill height measured to the bottom of the footing should include an additional seismic lateral earth pressure. Calculations and details should be updated as required. IBC 1807.2.2 3200 Cedar Street © 425.257.8810 O everetteps@everettwa.gov Everett, WA 98201 425.257.8857 fax everettwa.gov/permits Page 4 of 6
