Project Description

THE T-WING OF SUNNYBROOK HEALTH SCIENCES CENTRE (SHSC) IS A STANDALONE BUILDING THAT IS NOT CONNECTED ABOVE-GRADE TO THE ADJACENT S-WING ON THE EAST SIDE. THE T-WING ONLY CONNECTS THROUGH AN UNDERGROUND TUNNEL TO THE S-WING. THE STANDALONE T-WING PROVIDES OUTPATIENT SERVICES & IS CLASSIFIED AS A GROUP D ¿ BUSINESS & PERSONAL SERVICES OCCUPANCY. IT WAS PREVIOUSLY LOOKED AT AS A GROUP B, DIV 2 OCCUPANCY; HOWEVER, THIS INFORMATION WILL BE RECTIFIED & THE GROUP D OCCUPANCY OF THE T-WING WILL BE REFLECTED IN FUTURE SUBMISSIONS. FOR THE UPDATED OBC MATRIX, SEE APPENDIX B OF THIS ASP. THE GROUND FLOOR OF THE T-WING IS FULLY SPRINKLERED, AND A FIRE SEPARATION HAVING A FIRE-RESISTANCE RATING OF 1 H IS PROVIDED AT EACH END OF THE UNDERGROUND TUNNEL THAT CONNECTS THE T-WING TO THE S-WING ON THE EAST.THE ENTIRE GROUND FLOOR OF THE T-WING IS CONSIDERED AS ONE (1) FIRE COMPARTMENT IN A GROUP D OCCUPANCY. THEREFORE, THE CONVENIENT MEANS OF EGRESS ¿CORRIDOR TG009A¿ IS NOT CONSIDERED AS A PUBLIC CORRIDOR OR A CORRIDOR USED BY PUBLIC, AND THE REQUIREMENTS OF ARTICLE 3.3.1.4. ¿ PUBLIC CORRIDOR SEPARATIONS OF THE OBC 2012 DO NOT APPLY. BASED ON THE ABOVE, A FIRE SEPARATION HAVING A FIRE-RESISTANCE RATING IS NOT REQUIRED BETWEEN TWO ROOMS (¿PATIENT TRANSFER ROOM TG 212¿ & ¿CONTROL ROOM TG 211¿) SEPARATED BY A CONVENIENT MEANS OF EGRESS (CORRIDOR TG009A¿) IN GROUP D OCCUPANCY. CONSEQUENTLY, THE PROPOSED SLIDING DOOR TG212.1 OF THE ¿PATIENT TRANSFER ROOM¿ IS NOT REQUIRED TO BE RATED.AS DETAILED ABOVE, THE CURRENT DESIGN WILL MEET THE INTENT OF THE OBJECTIVE-BASED CODE.
