This design,paired with the operational issues of staffing and visibility, <br /> meets the intent of the code and provides equivalent fire resistance, effectiveness,health and safety. <br /> LIST SUBSTANTIATING EVIDENCE(REPORTS,STUDIES,ETC)—ATTACH COPIES OF DOCUMENTATION <br /> Telephone discussions with Steve Judson, State of Oregon Building Codes Division <br /> I hereby request approval to use an alternate material(s)and/or method(s)from that required by code as described above. <br /> Signed: Patrice Anderson, Steele Associates Architects Date: January 7, 2015 <br /> OFFICE USE ONLY <br /> 441 Approved �. <br /> Approved with conditions <br /> E Denied / <br /> Signed: Date: /'I/L0 / <br /> Page 2 of 2 <br /> G\FORMS\BLDG\B-37Altemate Material or Method Requestdoc <br />
