DATE: May 21, 2007 TO: Mitch Kent Mahlum Architects FAX: 206-441-0478 FROM: Ann Bullis, Assistant Building Official. RE: Plan Check 42007-0366 & 2007-0365 Project: Remodel Buildings F & H Project Address: 23200 100`x' Ave W During re -review of the plans for the above noted project, it was found that the following information, clarifications or changes are needed. Provide written responses to each comment and where changes can be found on the plans. Please submit revised plans/documents to Theresa Umbaugh, Permit Coordinator. 3. .. 4. Previous items 2b & 3: The Building Official did not approve the Alternate Design request for the reduced occupant load in the Staff Lounge, therefore 2 exits are required. Revise plans to show second exit, and also revise Sheet G-002 to show the correct use, occupant load and exits. Previous item 5: The egress gate detail has still not been provided. We only received the manufacturer's information sheet for the Detex EA -500 Exit Alarm. Sheet A-113 at the egress gates refers to detail 02/A402, which refers to 04/A-403 which does not show the egress gate detail (it shows an elevation of H31 which appears to also be an incorrect room number — please coordinate). Previous item 6 and Architect letter dated 5118/07: Update plans with code information provided in 5/18/07 letter. Also, update wall assemblies to be 1 -hour fire rated, and provide listed and tested assembly reference (i.e. from Gypsum Fire Resistance Design Manual, UL Directory, IBC Chapter 7 tables, etc.). Note the complete construction requirements of assemblies on the plans so they are constructed and inspected properly in the field. Provide listed and tested 1 -hour fire stopping assembly details and reference number (such as from. UL Directory), or list as deferred submittal on the coversheet of the plans.
