The fire-rated exterior walls on Grids G, C, 5, and 10 are required to be continuous through the floor and roof construction. Details should be included demonstrating the required construction. See IBC Section 705.6. 2. Continuing with the previous comment, the fire-rated exterior walls require parapets per IBC Sections 705.6 and 705.11. Details should be included in the drawings. The parapets should extend a minimum of 30 inches above the roof surface per IBC Section 705.11.1. Alternatively, the roof construction should comply with Section 705.11 Exception 4. Egress: 3. The stairways in the plans on Sheets A2.1 and A2.2 specify minimum total widths of 7'-6" including the intermediate wall. The plans should specify minimum clear widths of 3'-0"for each run. See IBC Section 1011.2 Exception 1. 4. The following comments should be addressed for the handrails per IBC Section 1014: a. The Code Plans on Sheet A0.2 do not appear to show the handrails correctly or consistently with the plans on Sheets A2.1 and A2.2. b. Extensions should be shown at the top of the southwest stairway on Sheet A2.2. c. The bottom extension in Section 2/A4.3 should be sloped. d. The handrails height in Section 2/A4.4 should be measured from the stair nosing, not the midpoint of the stair. Note that this dimension is correctly shown in Detail 5/A6.2; it is recommended that the dimension on the section be deleted. e. Detail 9/A6.2 should show the bottom extension as sloped and specify a minimum length of one stair tread past the bottom nosing. f. A detail for the continuous handrail condition wrapping around center walls at landings should be included in the drawings. 5. The southwest exterior stairway in Elevation 2/A4.2 should specify a maximum landing height above the adjacent grade not to exceed 30 inches. Alternatively, a guard should be provided. See IBC Section 1015.2. 6. The exit sign on Sheet A3.1 in the southwest stairway above door 1AB should be relocated to the Corridor 112 side of the door. See IBC Section 1013.1. 7.
