• • Mr. Paul Pikalov StroyCo Plan Check Number: 82106-003, First Building Review June 16, 2021 4. The Typical Deck Section on Sheet A.2 shows premanufactured post bases supporting the deck. It is presumed these are also intended for the lower landing. The following comments should be addressed: a. Additional information, including but not limited to the material of the base, should be specified in the drawings. Foundations should be decay-resistant construction. See Section R317.1.4. b. The bases should be founded at least 18-inches below the adjacent grade. See Sections R507.3.2 and R403.1.4.1, and EMC Section 16.01.010. c. Continuing with the previous comment, the lower landing is connected to the main deck and house via the stairway, and must also have a minimum 18-inch foundation depth. 5. Detail 2/A.2 shows proprietary lag screws spaced at 11 inches. The screws should be minimum 1/2-inch diameter at a maximum spacing of 9 inches. See Table R507.9.1.3(1). 6. Detail 4 specifies post attachments with bolts spaced at 2.5 inches. This does not appear sufficient to resist the moment resulting from the 200-pound load per Table R301.5. Calculations substantiating the connection should be submitted for review. Alternatively, the connection should be revised. 7. The following comments should be addressed for the guard shown in Detail 3/A.2: a. The plans should specify the guard connection to the house. See Section 106.1.1. b. The connection between the horizontal 2x framing to the guard post should be specified. The connection should resist a 200-pound load per Table R301.5. 8. The plans do not provide sufficient information for the construction of the stairs. Revised details should be submitted for review addressing the following comments: a. Detail 5/A.2 appears to show only two notched stringers with an effective depth of approximately 5 inches, which is not structurally adequate. See Tables R507.6. Alternatively, an engineered design may be performed per Section R301.1.3. b. The lx decking is not adequate to span 5 feet between the stringers. See Table R507.7. c. The handrail height should be specified per Section R311.7. d. A guard detail with connections should be provided. The guard, connection, and supporting framing (e.g., stair stringer) should be designed to resist a 200-pound load per Table R301.5. 9. The construction drawings should specify fasteners between the decking and structural framing per Section R507.7. 10. The construction drawings should specify field treatment of cuts, holes, and notches in preservative-treated wood per Section R317.1.1. 3200 Cedar Street ,/(7-,, 425.257.8810 everetteps@everettwa.gov ' ' Everett, WA 98201 -- 425.257.8857 fax everettwa.govjpermits
