Excerpt from UFC-600-1 Plans and Calculations. For new systems or modified systems, working plans and calculations must be prepared and submitted for approval by a registered professional fire protection engineer or an individual that has obtained National Institute for Certification in Engineering Technologies, Automatic Sprinkler Systems, Level III certification (minimum) or Special Hazards Suppression Systems, Level IV certification, in accordance with the applicable NFPA code. Submit the fire extinguishing system construction (shop) drawings to the appropriate components designated Fire Protection Engineer.

a Refer to Appendix C for occupancy hazard classification.

b Where listed quick-response sprinklers are used throughout the system, the design area in Table 4-1 may be permitted to be reduced without revising the density as permitted in NFPA 13 except for facilities that are required to comply with UFC 4-010-01, DoD Minimum Antiterrorism Standards for Buildings.

Note: The protection requirements identified in Table 4-1 are based on standard commercial practices followed throughout civilian industry for highly protected risk (HPR) properties. Table 4-1 represents the minimum requirements necessary to establish minimum comprehensive life, mission, and property loss prevention. Table 4-1 was adapted as a result from detailed studies by Factory Mutual of loss experience from 1956 to 1965, loss experience in selected occupancies from 1966 to 1977 and from 1981-1990, and fire test data.

4-2.3.2 Sprinkler Design Area Adjustments.

4-2.3.2.1 For dry pipe systems, the design area of sprinkler operation in Table 4-1 must be increased by 30 percent per NFPA 13.

4-2.3.2.2 The design areas in Table 4-1 must be increased by 30% for sloped ceilings that exceed a pitch of one in six.

4-2.3.3 The use of quick response automatic sprinklers (QRAS) is limited to wet systems.

4-2.3.4 Hydraulic Calculations. New sprinkler systems protecting areas of 139 m² (1,500 ft²) and greater must be designed using hydraulic calculations. Use of pipe schedule designs is strongly discouraged for any sprinkler system. Required discharge densities and areas of discharge operation are given in Table 4-1. Calculations must follow the format of NFPA 13. Pipe friction losses and equivalent lengths of pipe for fittings and valves must be in accordance with NFPA 13.

Note: Additions to existing pipe schedule systems may be designed using the pipe schedule method.

4-2.3.4.1 The designer (a fire protection engineer) will provide hydraulic calculations demonstrating that the design will provide an adequate water supply for the fire extinguishing systems. Hydraulic calculations will be submitted no later than the 35 percent design submission. Calculations must be based on recent water flow test data.
