Mr. Ismail Mohammad 2713 Maple Street, LLC Plan Check Number: B2101-051, Third Building Review April 22, 2022 Additional Comments: 15. Wall Type W4 on Sheet A4 is referenced for the existing exterior north wall of the building and indicates 2x4 stud framing and R-21 insulation. The insulation should be specified as spray - foam insulation or another insulation type that can achieve the required thermal performance. Alternatively, the wall should be confirmed to be 2x6 stud framing similar to the other walls. See Section R106.1.1. Structural 1. This comment has not been addressed. The proposed project includes structural work. The overlay of structural information on the architectural plans is not sufficient to specify the proposed structural work. In addition, the framing appears to be incomplete, including but not limited to the area around the stairs at the Second Floor. The construction of the new interior and exterior walls, foundations, and stair landings is not included. Structural drawing should be submitted that include framing plans, sections, details, construction schedules, fastening schedules, materials requirements, general notes, special inspection requirements, etc. Note that partial framing for the second floor is currently shown on the first floor plan, and the second floor plan shows unspecified framing. The drawings should substantiate compliance with the prescriptive requirements of the IRC. Alternatively, an engineered design may be performed for portions of the structural design per Section R301.1.3. See Sections R106.1.1 and R301.1. 2. This comment has not been addressed. A general fastener schedule should be provided per IRC Table R602.3(1). Providing a reference to this table in the drawings does not satisfy this requirement. In addition, the make and model of proprietary hardware should be specified where used for connections. 3. This comment has not been addressed. Typical details for the construction of the new walls should be included. The details should specify connections for the top and bottom framing plates to the existing structure. See additional comments below. See IRC Sections R106.1.1 and R301.1. 4. This comment has not been addressed. The proposed design includes modifications to the existing shear walls. The drawings should be revised to show the modified wall construction, including demolition and infill of walls. See additional comments below. See IRC Section R106.1.3. 5. This comment has not been addressed. The new and modified bearing and shear walls require new foundations, notably at the south wall where shear walls at the existing garage door openings. Details for the foundations should be included in the construction drawings. Existing interior footings, such as the ones presumed to support the new interior gravity posts, should be shown in the foundation plan. Note that it is not clear if Detail 602/S03 is intended as a new or existing foundation as it includes post -installed anchors. The construction drawings do not include a foundation plan to indicate where this detail applies.
