Project description

The proposed alternative solution would include the deletion of hose cabinets on all above grade floor levels of the building and installation of standpipe risers and 65 mm hose connections within exit stair shafts.Additional 65 mm hose connections are to be provided throughout the parking level & ground floor asrequired for spacing.The placement of a fire hose cabinet, containing a 30 m length of fire hose is proposed to be substituted with the following on the above grade floor levels.- System riser to be located in the exit stairs.- Riser to have 65 mm hose connections at the main landing of each floor (Class I System asper NFPA 14). No additional hose connections are proposed within the floor area wherethe distance does not exceed 61 m (as per NFPA 14 7.3.2.3.1). Additional hose valves to beprovided where the distance to any point on the floor area exceeds 61 m (as per NFPA 147.3.2.3.1). The OBC states the need to have 38 mm hose stations and 65 mm hoseconnections with fire hose coverage not to exceed 33 m (30 m hose + 3 m hose stream)(Class III System as per NFPA 14), and in this case we do not have 38 mm hoseconnections, so the 33 m fire hose coverage is not applicable. The requirements are notdirectly specified in the NBC, but NFPA 14 (7.3.2.3.1) states the travel distance shall be 200ft (61 m) for sprinklered buildings. We will also increase the residual pressure from 65 psias per the OBC to 100 psi as per NFPA 14.- Flow criteria to be compliant with Division B or the OBC.- Outlet of 65 mm hose valve to be angled towards the floor. See appendix A for photo / example. Thehose valve will be angled down as this hose valve position gives the responding fire crew the mostflexibility with hose maneuverability as the hose can be moved in any direction without kinks orwithout the fire crew from needing to attach a 45 degree or 90 degree elbow. Depending on thelocation and intensity of a fire, fire crews may setup in the stair on the floor below. By providing thehose valve outlet in a downwards direction it reduces the potential of hose kinks regardless of thedirection the hose needs to travel (toward the door to the floor, or towards the stair riser bring a hose
