• Plan Review Re-Submittal Gay Basement Remodel BW-2106-002 August 25, 2022 Page 3 of 3 d. The selected energy credits may require increases in the base performance requirements, such as increased thermal performance of the building envelope components. Where applicable, the base performance values should be revised for consistency with the selected energy credits. No Energy Credits are required for an existing residence not increasing floor area or change in use. See General Notes, Sheet A-O Structural 1. Sheet A-3 appears to show the Main Floor framing including the supporting posts extending through the Basement level. It is not clear if the posts are incorporated completely in the new walls. One or more posts are located in open space (e.g., center of Kitchen/Great Room, etc.). The locations of the posts should be shown in the Proposed Basement Plan on Sheet A-1. See / Sections R106.1.1 and R301.1. Existing beam support post locations for the existing basement are shown an Sheet A-1 2. Continuing with the previous comment, it is understood that structural modifications are not occurring. However, if modifications are required for the proposed construction, additional structural information including but not limited to framing plans, sections, details, material requirements, and fastener requirements (e.g., schedule, specify proprietary hardware, etc.) should be including in the construction drawings. See Sections R106.1.1 and R301.1. No J structural modifications are proposed. Removed and new interior walls are non-bearing partitions. 3. The project includes modifications to the exterior walls and foundation to widen existing or create new window openings at the Basement Level per Sheet A-3. Additional elevations and details should be provided to specify all of the construction requirements, including but not limited to demolition of the exterior wall, king and jamb studs, and support of existing floor framing. Fastener requirements should be specified. See Sections R106.1.1, R301.1, and ,R602.7, and Table R602.3(1). The new window wells for Emergency Escape and Rescue equires saw cutting existing concrete foundation/Retaining wall and thus removal of an additional 3' wide and 2'tall section of concrete. No alteration of existing construction supporting the floor and roof above is proposed or necessary. See Sheet A-4, Flag Notes 3/S-4 4. Continuing with the previous comment, the Floor Framing Plan on Sheet A-3 specifies new (2)2x6 headers for the modified and new window openings. The headers are required to support floor, wall, and roof loads. Calculations substantiating the headers should be submitted for review. The headers are anticipated to be fastened together for stability and should include / requirements. See Sections R106.1.1 and R301.1.3. No new headers are required or necessary. Headers previously shown in error on Sheet A-3 have been removed. [20212541 GayCityCorrectionLtr.003.5] SOUND INVESTIGATIVE ENGINEERS, LLC 33412 E Lk Holm Dr SE Auburn, WA 98092 (206) 255-0896
