WET PIPE SPRINKLER SYSTEM

sprinkler discharge pattern and coverage. Provide wet pipe sprinkler system in areas indicated on the drawings F-001, F-101, -102, -103, and -110.

B. Except as modified herein, the system shall be designed and installed in accordance with NFPA 13 and UFC 3-600-01. Pipe sizes shall be determined by hydraulic calculation. Design any portions of the sprinkler system that are not indicated on the drawings including locating sprinklers, piping and equipment, and size piping and equipment when this information is not indicated on the drawings or is not specified herein. The design of the sprinkler system shall be based on hydraulic calculations, and the other provisions specified herein.

1.3 PERFORMANCE REQUIREMENTS

A. Hydraulic calculations shall be in accordance with the Area/Density Method of NFPA 13 as modified by UFC 3-600-01.

1. Water velocity in the piping shall not exceed 20 ft/s.

2. Margin of Safety for Available Water Flow and Pressure: 10 percent, including losses through water-service piping, valves, and backflow preventers.

3. Sprinkler Occupancy Hazard Classifications:

a. Building Service Areas: Ordinary Hazard, Group 1.
