City of Everett Plan Review Comment: <br /> On Sheet A00o, the Type of Construction is indicated as///B, but the building's existing <br /> conditions exceed the number of stories for l//B construction per Table 504.4 at/31 stories <br /> for a non-sprinklered building. The number of stories for this structure appears to be 171 <br /> stories. Given the number of stories, the type of construction may be closer to satisfying a <br /> Type 11/A building, requiring 1-hr fire protection to the primary frame. Please indicate, if the <br /> new interior construction provides this protection, for instance at the columns at grids 3/E <br /> and 5/E as it does not appear to indicate this on Sheet A900. /BC504 and Table 601. <br /> Applicant's Response: <br /> Based on our evaluation of the existing conditions,we believe the building classification <br /> does not conform to Type IIIA. Non-sprinklered Type IIIA structures of type B occupancy <br /> are limited to 65 feet in height (Table 504.3) and have a story limitation of 5 (Table 504.4). <br /> The existing building is stepped with portions that are both 7 and 3 stories high. However, <br /> there is no building separation between these areas and therefore cannot be classified as <br /> two separate buildings.The building is therefore considered 7 stories high. <br /> The building is more typical of a Type IB due to the number of floors and the occupancy. <br /> However,the presence of existing building elements that are combustible (wood floors) <br /> would indicate that the building is non-compliant with current building code. <br /> Occupancy: B- Business(existing and proposed) Section 304.1 <br /> Fire sprinkler protection: Basement only <br /> Building Height:7 floors Table 504.3/504.4 <br /> Primary Structural Frame: Concrete Table 601 <br /> Floor Construction: Concrete (typical) &Wood (above proposed TI) Table 601 <br /> tva architects, inc. <br /> 920 sw sixth avenue suite 1500 portland,oregon 9924E <br /> phone:503 220 0668 www.tvaarchitects.com <br /> Robert Thompson,FAIA Tim Wybenga,LEED AP?Pamela Saftler,AIA,IIDA`Mandy Butter,AIA <br />
