10、D FACILITIES GUIDE SPECIFICATIONSReferences are in agreement with UMRL dated 01 March 2008*SECTION 21 13 13.00 20WET PIPE SPRINKLER SYSTEM, FIRE PROTECTION04/08*NOTE: This guide specification covers the requirements for wet pipe fire protection sprinkler systems.Comments and suggestions on this guid
11、e 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
12、).Use of electronic communication is encouraged.Brackets are used in the text to indicate designer choices or locations where text must be supplied by the designer.*PART 1 GENERAL*NOTE: The Designer will edit this section for either a performance-designed system or a fully designed system as applica
13、ble.This 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 sprinklers will be designed by the Contractor.The Designer will provide the following information in the contract documents fo
14、r performance designed systems. This information will be in accordance with UFC 3-600-01. For NAVFAC projects, also SECTION 21 13 13.00 20 Page 3Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-include requirements of UFC 3-600-10N.(1) Show the layout
15、 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. (2) Show location and size of service mains, interior feed mains, control valves, sprinkler risers, drain lines
16、, sectional valves, and inspectors 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 sy
17、stem (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
18、 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 sy
19、stem 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
20、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) Highlight all concealed spaces on the drawings that require sprinkler protection, such as s
21、paces above suspended ceilings that are built of combustible material or that can contain combustible materials, such as storage, and communication cabling that is not fire-rated.(9) Provide details on the drawings of pipe restraints for underground piping. This includes details of pipe clamps, tie
22、rods, mechanical retainer glands, and thrust blocks. Include size of wall or floor sleeve if required to meet earthquake SECTION 21 13 13.00 20 Page 4Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-requirements. When connecting to an existing water d
23、istribution system, waterflow tests will be conducted in accordance with UFC 3-600-01to determine available water supply for the sprinkler system. The Designer of Record shall either perform or witness the waterflow test. The waterflow test results (including date test is performed) should be includ
24、ed 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 the Designer to participate or witness the waterflow test will be necessary. The need for fire pumps
25、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 UFC 3-600-01 and , NFPA 13 for a fully operationa
26、l system. For NAVFAC Projects this list also includes UFC 3-600-10N.*1.1 REFERENCES*NOTE: This paragraph is used to list the publications cited in the text of the guide specification.
