Construction 1. UL listing U428 requires proprietary GWB. As generic Type X is not in the listing, the types of approved GWB (mostly Type C) should be shown on the plans for wall types S, T & W/A8.01. a. Note 6 on Sheet A8.01 indicates the requirement of referring to the UL listing for GWB type, however the three partition types above could cause confusion in the field for the building inspectors. Response: Revised gyp board at partitions S, T, and W to be Type `C' to remove proprietary requirement. See sheet A8.01 for revisions. 2. It is not clear how wall type HcA/A8.01 will provide two-hour fire -resistance as the 2nd layer of GWB needed for 2-hour fire -resistance stops above the ceiling. Response: Revised note for HcA wall type to be 1-HR rated, see sheet A8.01. All locations of this wall type within the project occur at 1-HR rated walls. There are no 2-HR rated walls for this type. 3. The following comments apply to the horizontal shaft assemblies 17 & 21 /A8.01 Listing AER-09038): a. The listing requires Type C GWB vs. the Type X GWB shown on the details. b. Please verify that the studs chosen do not exceed Span Table 1 provided in the listing. Response: Revised details 17 and 21 on A8.01 to indicate Type `C' gyp board. Revised note to reflect limits of Span Table 1 to be met in performance design of studs. 4. Shaft detail 16/A8.01 appears to use both UL 469 for the vertical portions and AER-09038 for the horizontal portions of the assembly. Please verify as UL 469.allows Type X GWB for walls however AER-09038 requires Type C for horizontal applications. Response: Revised detail 16/A8.01 to show Type `C' gyp board, please see revised sheet. 5. Listings and references should be provided for the partition STC's shown on Sheet A8.01 where required by Section 1207.2 Response: References have been added for STC designated walls, please see revised sheet A8.01. 6. Walls separating the sleeping rooms from each other and sleeping rooms from the corridor/other rooms (FbA, NbA, NA, etc.) shown with assemblies that have less than 50 STC on Sheet A8.01.
