The plans indicate that smoke partitions are required along the corridors and Hall 215 shown on <br />Sheet A1.0. Some wall sections are not identified or specified to be full height. See IBC <br />Sections 107.2.1 and 710.4. <br />2. The doors penetrating the corridor smoke partitions are required to create an effective barr er <br />to prevent the passage of smoke. This requirement should be specified by the Door Schedule <br />on Sheet A9.0. The doors should comply with UL 1784. See IBC Sections 407.3.1 and <br />710.5.2.2. <br />3. The modified areas are anticipated to require modifications to the air ducts. See IBC Sectic n <br />107.2.1. The following comments should be addressed: <br />a. The locations for the air supply and return vents should be shown in the reflected ceiling <br />plans. See IBC Section 1203.1. <br />b. The locations of ducts penetrating the smoke partitions should be shown. Smoke dampers <br />should be specified. See IBC Sections 710.8 and 717.5.7. <br />4. The drawings should include a detail for penetrations through the smoke partitions. See IEC <br />Section 710.6. <br />5. Cover Sheet G1.0 and Floor Plan A1.0 indicate work scope Alternate #1 for Garbage Room 214. <br />The following comments should be addressed: <br />a. The scope should be included in the current project or removed from the drawings. Se,� <br />IBC Section 107.2.1. <br />b. The wall infill identified by Keynote 1.19 along Hall 215 is a fire -rated wall. The minims m <br />fire rating for the wall should be specified. The minimum rating appears to be one hou, per <br />IBC Table 509. <br />c. Keynote 1.19 stating to provide construction matching the existing is not sufficient. A detail <br />for the required construction should be provided. The detail should reference a listed tested <br />assembly providing the minimum required fire rating. See IBC Section 703.2. <br />d. The Door Schedule on Sheet A9.0 specifies a door with a 45-minute rating. The minim im <br />rating should be one hour for a one -hour fire barrier. See Section 509.4.1, and Tables 509 <br />and 716.5. <br />6. The building construction Type is I -A per the Project Data on Sheet G1.0. The gravity columns <br />require minimum one -hour fire -protection per Table 601 (i.e., "primary structural frame'). The <br />column covering at Grids 2/E and 2/F has been removed and must be replaced. Details for <br />listed and tested assemblies should be provided. See IBC Sections 703.2 and 704.2. <br />7. The new walls appear to create new or reframed shafts at multiple locations, including but not <br />limited to Grids C/2.5, F/3, and F/3.3. The minimum rating for the shaft walls should be <br />specified. Details for listed and tested assemblies should be provided. See IBC Sections 70.2 <br />and 713.4. <br />O3200 Cedar Street 425.257.8810 everetteps@everettva.gov <br />Everett, WA 98201 425.257.8857 fax everettwa.gov/permits <br />5g:e2 �f 3 <br />
