i • • Ms. Courtney Crosby Plan Check Number: B2004-017, Second Structural Review August 5, 2020 his comment has not been completely addressed. The response appears to indicate that the deck is laterally supported by the house. In lieu if independent support, the house is required to laterally support the deck in both principal directions. Details for the connections should be included in the construction drawings. Calculations substantiating the connection of the deck to the house should be submitted for review. The minimum lateral force should not be less than required by ASCE 7-10 Section 12.1.3. See IBC Sections 1604.1, 1604.4, and 1613.1, and ASCE 7-10 Section 12.12.3. The structural and drawings fully support a non-lateral deck. That is the independent support from our Structural Engineer. We have now included how it connects, though it is irrelevant for the purpose of this deck. Miscellaneous: 13. This comment has not been completely addressed. The revised drawings include improved details of the connections. However, the details cannot be completely reviewed due to deficiencies in the framing plans. In addition, the 2x12 blocking is not provided with a defined connection to the supporting framing opposite the post connections. It is noted that the proposed connections to the rim joists may not be adequate depending on the support conditions for these joists, which at a minimum appears non-existent for the east side of the structure; see additional comments above regarding the east joist. The "Guard Post on Inside of Rim Joist" detail also appears structurally questionable, but cannot be fully reviewed at this time. Drawing D clearly outlined replacing the Rim and End Joist with 2x12 joists (3) and it was outlined with specific connection information. We did expand on this, however, on Drawing D. Original Comment: This comment has not been completely addressed. The posts, connections, and supporting framing for the guards shown in Post Details 1 and 2 should comply with IBC Section 1607.8.1. Calculations substantiating the design should be submitted for review. See IBC Section 1604.1. Additional Comments: 14. Portions of the construction drawings have been produced by a licensed engineer registered in the state of Washington. The drawings are required to bear a seal and signature of the architect. See WAC 308-12-081. My husband and I were "the architect,"of the construction documents, and Engineers did/stamped the Structural Work. I'm happy to make a seal for you on the Construction documents, but I'm pretty sure we will just sign them. CI S.The protection against whether for the structural framing (i.e., beams and posts) of the proposed deck are not clear. The framing should be protected against the weather, or constructed of preservative-treated or naturally-durable wood. Cuts and holes in preservative- treated wood should be coated with preservative treatment. Fasteners exposed to weather or installed in preservative-treated wood should be corrosion resistant and compatible with the material it is installed in. See IBC Sections 107.2.1 and 2304.12. All listed fasteners in the 06/05 submission met this criteria. All preservative treated wood will be treated according to the code. See Drawing B as this information has been added to the drawing. +s\ 3200 Cedar Street j T 425.257,8810 everetteps@everettwa.gov t \ /i `-''-' Everett, WA 98201 �-- " 425.257.8857 fax everettwa.gov/permits Page 6 of 7
