For ease of conversation, the questions are responded to in numerical format; however the original document posted the questions in bullet form. Please note that I am not currently able to completely respond to the questions posted. The code contains many requirements that have several possible solutions that are chosen by the design team and not prescribed by the jurisdiction. Rather than respond with a chain of if/than scenarios, I have tried to follow the design parameters as previously discussed, however the bulk of discussion is still based on assumption and probable decisions that need to be further substantiated by analysis from the design team. 1. Occupancy type: Based on the description of occupants living in the building and services provided for the occupants, the building should be shown to comply with the provisions within the current code for a Group I-1 and S-2 Occupancy. As the building was previously a Group R/S-2 Occupancy, the change of occupancy requirements of Section 3408 will be required to be followed. 2, sprinkier and fire alarm requirements: Everett Municipal Code chapter 16.76 and the 2006 IBC each require the building to be fully alarmed and sprinklered. Section � 903.2.6 of the IBC permits an NFPA 13 or 13R system in the Group I-1 Occupancy. � Although a sprinkler system is required throughout the structure based on the occupancy type, the type of sprinkler is not specified. The type of sprinkler chosen for this project will create differences in requirements for many things referred to in the initial letter. 3. Draft stops: Draftstops in hurizontal assemblies are not required for this building when Ij sprinkled with an NFPA 13 system per Section 717.3.3. NFPA 13 contains additional requirements; however one method of compliance is that spaces rr�ust be firestopped into volumes not to exceed 160 cubic feet. 4. Type of construction: Type V-A construction is permitted for Group I-1 Occupancies. A full building code analysis will need to be provided to determine whether or not thi� building complies as V-A construction, with or without the area separation wall, and with y2 _:;Ory;•")!lor9ubr F[crtmcn;: ENGWEI=RIVG/ PUBLIC SEf�!ICFc nlVlz':nN � '?00 Codar Street• Everett, WA 98201 • (425)257-SS00• Fax(4'�Si='i' %3ft�6
