22、cordance with the current edition of MIL-HDBK-1008 and NFPA 14. Provide pipe-sizing calculations to the Division Fire Protection Engineer (FPE) for review. Class I standpipes are for fire department use only and will normally be the type provided. Wet standpipes must be protected from freezing. It i

23、s NAVFAC policy not to provide hose on standpipes except in unique situations as approved by the Division FPE. In low and intermediate height buildings (up to 75-ft in height), use of manual-dry standpipes is normally dictated by economics. In high rise buildings, the time required to fill the pipin

24、g with water and the pressure involved normally dictate automatic standpipes.The following clarification is provided regarding the design of standpipe systems. The two primary factors to consider are type of system (manual vs. SECTION 21 12 00 Page 5Provided by IHSNot for ResaleNo reproduction or ne

25、tworking permitted without license from IHS-,-,-automatic) and system design pressures. Unless otherwise directed by the Division FPE, standpipe systems shall be designed as follows:1. For buildings less than 75-ft, standpipe systems shall be designed as “Manual Standpipe Systems” as defined in NFPA

26、 14. The system piping shall be hydraulically designed to provide the required flow rate at a minimum residual pressure of 65 psi at the hydraulically most remote 2-inch hose connection. In combination sprinkler-standpipe systems, necessary fire booster pumps shall be sized to support the sprinkler

27、demand only. The fire department shall supplement the standpipe system via the fire department connections to provide the necessary flow and pressure. The water supply must be evaluated to ensure the available capacity will support the minimum standpipe system flow rates.2. For buildings 75-ft up to

28、 150-ft in height, standpipe systems shall be designed as “Automatic Standpipe Systems”as defined in NFPA 14. Fire pumps shall be sized to consider the standpipe demand as specified in NFPA 14. The system piping shall be hydraulically designed to provide the required flow rate at a minimum residual

29、pressure of 65 psi at the hydraulically most remote 2-inch hose connection. 3. In buildings 150-ft in height and greater, standpipe systems shall be designed as “Automatic Standpipe Systems”as defined in NFPA 14. Fire pumps shall be sized to consider the standpipe demand as specified in NFPA 14. The

30、 system piping shall be hydraulically designed to provide the required flow rate at a minimum residual pressure of 100-psi at the hydraulically most remote 2-inch hose connection.*System design and manufacturers products shall be in accordance with the required and advisory provisions of NFPA 14 exc

31、ept as modified herein. Standpipe system shall be designed by hydraulic calculations.Provide sprinkler portion of system under Section 21 13 13.00 20 WET PIPE SPRINKLER SYSTEM, FIRE PROTECTION. Each system shall be designed for earthquakes and shall include materials, accessories, and equipment insi

Devices and equipment shall be UL Fire Prot Dir listed or FM APP GUIDE approved for fire protection service. In the publications referred to herein, the advisory provisions shall be considered to be mandatory, a

40、eview submittal description (SD) definitions in Section 01 33 00 SUBMITTAL PROCEDURES and edit the following list to reflect only the submittals required for the project. Submittals should be kept to the minimum required for adequate quality control.A “G” following a submittal item indicates that th

41、e submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G” if the submittal item is not complex and can be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in contex

42、t of the project.For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the “G“ designation to indicate the approving authority.
