USACE / NAVFAC / AFCESA / NASA UFGS-21 13 18.00 10 (November 2008) ----------------------------------- Preparing Activity: USACE Superseding UFGS-21 13 18.00 10 (October 2007) UNIFIED FACILITIES GUIDE SPECIFICATIONS References are in agreement with UMRL dated January 2009 SECTION 21 13 18.00 10 PREACTION AND DELUGE SPRINKLER SYSTEMS, FIRE PROTECTION 11/08 NOTE: This guide specification covers the requirements for preaction and deluge fire protection sprinkler systems. Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable items(s) or insert appropriate information. Remove information and requirements not required in respective project, whether or not brackets are present. Comments and suggestions on this guide specification are welcome and should be directed to the technical proponent of the specification. A listing of technical proponents, including their organization designation and telephone number, is on the Internet. Recommended changes to a UFGS should be submitted as a Criteria Change Request (CCR). PART 1 GENERAL NOTE: Because preaction systems are more costly, less reliable, and require more maintenance than wet-pipe systems, they should be used only where justified by occupancy conditions. Deluge systems are "open head" systems which discharge all sprinklers upon system actuation. The use of deluge systems should be limited to special hazard situations. The Designer will edit this specification section for either a performance-designed system or a fully designed system as applicable. This specification section is primarily intended for performance designed systems, i.e. systems where the size, layout, and support of branch lines and cross mains, and the layout of sprinkler heads will be designed by the Contractor. The Designer will provide the following information in the contract documents for performance designed systems. This information will be in accordance with Military Handbook 1008C. (1) Show the layout and size of all piping and equipment from the point of connection to the water supply, to the sprinkler cross mains. The contract drawings must include a detailed sprinkler riser diagram. Water velocity in the piping should not exceed 6 m/s (20 ft/s). (2) Show location and size of service mains, interior feed mains, control valves, sprinkler risers, drain lines, sectional valves, and inspector's test valves and switches on the drawings. (3) Specify waterflow data including hydrant flow results, including the location where the hydrant flow test was conducted, the location and size of existing mains and new water supply lines that will serve the sprinkler system (including all supervisory valves), and the location and size of all risers. (4) Highlight or clearly indicate the area(s) to be protected by sprinklers on the drawings. (5) Specify waterflow requirements including the design density, design area, the hose stream demand (including location of the hose stream demand), the duration of supply, and sprinkler spacing and area of coverage in this section. (6) Show the location of the backflow preventer (including provisions for a drain and access for maintenance) where the potable water supply system is at risk of contamination by the sprinkler system on the drawings. (7) Show all provisions necessary for forward flow testing of the backflow preventer at system demand as required by NFPA 13 on the drawings. Indicate location of all components and required items including test ports for pressure measurements both upstream and downstream of the backflow preventer, a drain to the building exterior, and appropriate, permanent means of disposing of the large quantity of water that will be involved in the initial test and subsequent annual tests. (8) Air compressors, including controls and complete installation details, including piping, control valves, mounting base. (9) Highlight all concealed spaces on the drawings that require sprinkler protection, such as spaces above suspended ceilings that are either built of combustible material or are intended for storing combustible materials. (10) Provide details on the drawings of pipe restraints for underground piping. This includes details of pipe clamps, tie rods, mechanical retainer glands, and thrust blocks. When connecting to an existing water distribution system, waterflow tests will be conducted to determine available water supply for the sprinkler system. The Designer will either perform or witness the waterflow test. The waterflow test results (including date test is performed) should be included in the Project Development Brochure; however it is critical that the waterflow test results be included in the design documents no later than the concept submission. Note that the availability of and funding for the Designer to participate or witness the waterflow test will be necessary. The need for fire pumps or a water tank can in many instances have a significant impact on the amount programmed for design and construction of a facility. A fully designed system will include the items listed above and all additional information required that is required by Military Handbook 1008C and NFPA 13 for a fully operational system. 1.1 REFERENCES NOTE: This paragraph is used to list the publications cited in the text of the guide specification.
