Mr. Ismail Mohammad 3314 Rockefeller Avenue, LLC Plan Check Number: B2005-037, Second Building Review November 17, 2020 assemblies are also required to be fire -rate. Details for the supporting framing should be provided with a minimum protection of one -hour. See Section R302.3.1. d. The fastening of all framing, including the floor sheathing, should comply with IBC Section 722.6.2.6 and Table 2304.10.1. e. The one -hour assembly is required to extend outside the exterior door on the west side. The GWB will be exposed to weather. A detail complying with the requirements for fire - rating and weather exposure should be submitted for review. f. The one -hour ceiling is required to be continuous to the exterior surface of the walls, or until abutting wall construction (e.g., solid concrete walls) sufficient to provide the required protection. Details at the building perimeter, including all window and door openings, should be provided. g. Plan Note 3 on Sheet 3 referencing the interior ceiling assembly does not provide information and should be removed. See Section R106.1.1. 8. The Project Narrative on Sheet 1 includes reference to the "detached two -car garage" that is located on the lot. The garage is a separate building and not included in the scope of work under this permit, and should be removed from the narrative. See Section R106.1.1. 10. The top plate in section W1 on Sheet 6 appears to be in -contact with the basement wall. The plate should be preservative treated per Section R317.1. 13. The original comment stated that a building section should be provided showing the existing construction of the main floor. The section on Sheet 6 does not provide the required information. See Section R106.1.1. The following comments should be addressed: a. The size and spacing of the floor joists should be specified. See also comment 6(b) above. b. The main floor framing appears to be supported by headers at a minimum of two locations (i.e., bedroom window, crawl space access); other locations may occur. Additional requirements and details for the construction at these locations should be provided. The headers should comply with Table R602.7(1). Alternatively, headers may be designed per Section R301.1.3; calculations substantiating the design should be submitted for review. c. Continuing with the previous comment, the construction of the bedroom header is not clear and does not appear likely to comply with the prescriptive requirements. In addition, the support locations, and potential notching of the floor joists, is not clear. A detail should be provided clarifying the construction at this location. Joists should be provided with engineered connections or supports where such support does not comply with Section R602.3. d. Headers should be supported by stud framing per Section R602.7.5. Alternatively, supports may be designed per Section R301.1.3; calculations substantiating the design should be submitted for review. In either case, details for the construction should be submitted for review. Additional Comments: 20. The "As -Built Basement" plan on Sheet 3 specifies demolition of the existing gas furnace and water heater. The appliances are presumed to serve the Main Floor unit.
