Mr. Ismail Mohammad 2713 Maple Street, LLC Plan Check Number: B2101-051, Second Building Review February 10, 2022 2. Sections B/A4 and D/A4, Wall Type "W3", and Detail 4/A6 specify a one -hour rated party wall between the units. See Section R302.3. The following comments should be addressed: a. The reference for Section B/A4 states "B/A2.3". See also Section "A/A2.3 on Sheet A4. The references should be updated. Other references in the drawings should be similarly revised. b. A party wall is not required to provide the required fire protection. The wall type may be revised to a simpler construction as the designer's discretion. c. The wall(s) should be continuous through the floor line. Alternatively, solid blocking matching the out -to -out surfaces of the GWB may be provided. d. Section D/A4 should be referenced in the plans on Sheet A2. 3. Section C/A4 shows the exterior wall on the east side of the building. The wall has a FSD=O and is required to be a minimum one -hour rated wall per Table R302.1(1). The wall should be continuous from the foundation to the roof sheathing. Alternatively, solid blocking matching the out -to -out surfaces of the GWB may be provided at both the floor and roof framing. The rated construction should also be provided for the parapet extending above the roof. 4. The floor plans on Sheet A2 show exhaust fans located adjacent to or near the east fire -rated exterior wall, including but not limited to the range exhaust fans. Openings into or through this wall are not allowed for air ducts for FSD<3 feet, including interior member penetrations into the wall cavity space. All ducts must be located outside the wall assembly. The proposed duct routes should be shown in the plans. Details should be provided where ducts will be located in chases; the chases should be shown in the plans. See Section R106.1.1 and Table R302.1(1). 5. Smoke and CO alarms should be provided per IRC Sections R314 and R315. The locations of all alarms should be shown on the plans. A note should be included requiring the alarms to be hardwired, interconnected, and provided with back-up battery power as required. Alarm clearances should comply with Section R314.3 Item 4 and Section R314.3.1. 6. Section A/A4 shows a 6'-8" clearance for the stairs dimensioned to the tread surface. The clearance should be dimensioned to a line connecting the stair nosings. The clearance dimension should be revised. The floor framing above may need to be revised. See Section R311.7.2. 7. Sections C/A4 and D/A4 specify a sleeper floor system at the Main Level per Floor Type 73". The following comments should be addressed: a. Sheet A4 does not include this floor type. It appears the Type 72" may be intended. The design should be revised as needed. See Section R106.1.1. b. The floor will be raised above the exterior grade. The egress door and landing are required to comply with Section R311.3.1. A section through the egress door threshold should be included in the drawings. 8. The Main Floor Plan 1/A2 appears to show heat pump units under the egress windows on the exterior of the building. The heat pumps may prevent proper emergency egress and rescue activity, and should be relocated. The heat pump locations should also be shown in the Site Plan and elevations on Sheets Al and A3, respectively.
