The A occupancy does not require fire sprinklers per section 903.2.1.3. Table 508.4 does <br /> require occupany separation of 2-HR or 1-HR if sprinkled. Due to the Group R requiring the building <br /> to be sprinkled 2 systems, a 13(commercial)and 13R(residential)would be reguired. In an effort to <br /> avoid installing these 2 systems we are requesting the 13R system be installed throughout the <br /> building and a 1-HR separation as required between occupancies.Additionally 1 co/smoke detector <br /> will be installed in the assembly area and detectors installed in the R occupancy per code. The intent <br /> Is to protect the R occupant. Two Independent fire systems are a fininacial burden w/limited benefit. <br /> laaaySUBSTANTIA`EINO EVIDENCE(REPORTS,STUDIES,ETC) ATTACH COPIES OFDOCUMENTATION... <br /> This request was approved by Warren Jackson on August 9th 2016.There have been sfight modifications to the orginal <br /> plans hence this re-reguest The building footprint in 300 sf larger but the 2nd floor has been reduced eliminating the <br /> 2 sleep moms ucing the apartment size. <br /> taw I hereby req aap royal_ �to`use an alternate material(s)and/or metbod(s)fro that r quired by code as described above. <br /> Signed: Date: 4/2-ci I I <br /> PlIt-tFL In{G.LLV-&MV <br /> Approved <br /> ❑Approved with conditions <br /> ❑Denied <br /> Signed: � t--: ��Date: �r <br /> — � 1 <br /> Page 2 of 2 <br /> G'\FORMS\BLDG\B-37AI(emate Material or Method Requestdac <br />
