Y • • 3 <br /> • <br /> 5. Floor/ceiling assembly FW-6/A-9.1 requires proprietary gypsum floor topping, Levelrock <br /> brand floor underlayment and Type C GWB per listing GA File No. FC 5011. <br /> 6. Two-hour wall type C-1-7 is shown for the stair enclosures on PL 2 and the 1st floor and <br /> the elevator shaft on the 2nd floor, however the wall type is not provided on the A-9.x <br /> sheets. <br /> 7. The wall callout M-1-5 for the trash chute detail on Sheet A-10.2 should be revised to a <br /> two-hour wall type. Section 713.4 <br /> 8. The trash room should be shown surrounded by minimum two-hour walls and 90-minute <br /> openings (including the coiling door). Section 713.13.4 <br /> 9. Please provide a detail showing the continuous two-hour shaft construction (elevators, <br /> stairs and mechanical) per Section 707.5: <br /> a. Through or abutting a one-hour floor/ceiling assembly. <br /> b. Fire-stopped or jointed at a concrete floor/ceiling assembly. <br /> c. Continuous to the underside of the roof sheathing. <br /> 10.The plans should note that the exhaust fans in the dwelling units will be provided with <br /> ceiling radiation dampers. Section 717.6.2.1 <br /> 11. If insulation is provided within the roof assembly cavities as shown on Sheets A-8.x, the <br /> result is that the insulation must be lowered a minimum of 1"(as long as the listing allows <br /> it) and the resultant 1"attic space must then be ventilated. Section 1203.2 (or exceptions <br /> per 1203.3) <br /> Egress <br /> 1. Because it only joins two floors, Stair C is not an interior exit stairway (rated) but an exit <br /> access stairway (no fire-rating required) that provides a means of egress from Level P2 <br /> up and through Level P1: <br /> a. A barrier should be provided within the stairway to prevent persons from trying to <br /> exit through to the lower P2 floor. Section 1023.8 <br /> b. For clarity, exit door P108 should have a revised nomenclature on the plans to <br /> confirm it is a door (appears to be a window). <br /> c. The exit sign at door P1-SC into Stair C from Level P1 should be removed. Section <br /> 1013 <br /> d. An exit sign and egress lighting should be provided at exterior exit door P108. <br /> Section 1013 <br /> 2. The occupant load of Level P1 is greater than 10 persons and therefore the coiling garage <br /> doors may not be used as part of the required means of egress per Section 1010.2: <br /> a. The NE corner of the garage has an occupant load less than 29 and the common <br /> path of travel is less than 100' and therefore complies.
