41* Mr. Douglas Acheson 2506 Baker Avenue Plan Check Number: B2005-039, First Building Review June 9, 2020 compliance with the IRC. Other comments provided in this review are based on demonstrating compliance with the IBC. 2. The construction drawings do not include material requirements for the structural systems. Material properties, connection requirements, fabrication and coating requirements, and other information required to perform the structural work should be specified in accordance with the following design standards: a. Concrete: IBC Sections 1901.5. b. Wood: IBC Section 2306.1 and AWC NDS-15. The construction drawings indicate that the plan dimensions for the awning are 8 feet by 28 feet. However, the position of the posts and framing spans are not clear. In addition, the posts appear to pass through the structure for the existing deck. Framing plans for both the plans and the existing deck should be submitted for review. The plans should be drawn to - scale and include dimensions for the extent of the framing. See IBC Sections 107.2.1 and 1603.1. 4. Continuing with previous comment, it appears that the existing deck framing may be supported by the new posts. Sections and details clarifying the intended construction should be submitted for review. If the new posts are not supporting the existing structure, an additional foundation plan should be included showing the existing and new foundations. See the previous comment for additional information. See IBC Sections 107.2.1 and 1603.1. Foundation System: 5. The proposed post foundations appear to be located in close proximity to the existing house foundations. The existing foundations should be shown in the building section and verified to not impact the existing structure. See IBC Section 1804.1. 6. The project includes wood posts embedded concrete encasements. The posts should be pressure -treated wood. Cut ends should be coated with a preservative treatment complying with AWPA U1. with It is recommended that the foundations specify a minimum 3-inch concrete cover to the wood surfaces on all sides. See IBC Section 2304.12.3.1. Gravity System: 7. Calculations should be submitted substantiating the design of the structural framing. The design should consider the applicable load combinations per IBC Section 1605 for the combined effects of dead, live, snow, wind, and seismic loading. Loads from the existing deck should be included where supported by the new posts and foundations. See IBC Sections 1604.1, 1604.2, and 1604.4. The evaluations should include, but are not limited to: a. Foundations. b. Posts. c. Glulam beams, including cantilevers. d. Roof decking, including cantilever.
