1.2 SYSTEM DESCRIPTION

a. Furnish piping offsets, fittings, and any other accessories as required to provide a complete installation and to eliminate interference with other construction. Install sprinkler piping and heads over and under ducts, piping and platforms when such equipment can negatively affect or disrupt the sprinkler discharge pattern and coverage.

b. Provide pre-action sprinkler system(s) connected to existing system in areas indicated on the Drawings. The sprinkler system shall provide fire sprinkler protection for the entire area. Except as modified herein, the system shall meet the requirements of NFPA 13 and NFPA 72.

The existing sprinkler system is a single interlocked system that requires the actuation of an alarm initiating device to open the water control (deluge) valve.

c. Design any portions of the sprinkler system that are not indicated on the Drawings or are not specified herein, including locating sprinklers, piping, and equipment, and size piping and equipment.

Determine pipe sizes which are not indicated on the drawings by hydraulic calculations.

1.2.1 Hydraulic Design

Hydraulically design the system to discharge a minimum density of 0.20 gpm/square foot over the hydraulically most demanding 2,500 square feet of floor area. The minimum pipe size for branch lines in gridded systems shall be 1-1/4 inch. Hydraulic calculations shall be in accordance with the Area/Density Method of NFPA 13. Water velocity in the piping shall not exceed 20 ft/s.

SECTION 21 13 18.00 10 Page 2

1.2.1.1 Hose Demand

Add an allowance for exterior hose streams of 250 gpm to the sprinkler system demand at the point of connection to the existing water system.

1.2.1.2 Basis for Calculations

Base the design of the system upon a water supply with a static pressure of 80 psi, and a flow of 1,267 gpm at a residual pressure of 70 psi.

Contractor shall perform a fire hydrant flow test and submit data to Contracting Officer prior to preparing design. Water supply shall be presumed available at the point of connection to existing. Base hydraulic calculations upon the Hazen-Williams formula with a "C" value of 120 for steel piping, and 100 for existing underground piping.

a. Outline hydraulic calculations as in NFPA 13, except that calculations shall be performed by computer using software intended specifically for fire protection system design using the design data shown on the drawings. Submit hydraulic calculations, including a drawing showing hydraulic reference points and pipe segments. Software that uses k-factors for typical branch lines is not acceptable. Calculations shall substantiate that the design area used in the calculations is the most demanding hydraulically.

b. Plot water supply curves and system requirements on semi-logarithmic graph paper to present a summary of the complete hydraulic calculation. Provide summary sheet listing sprinklers in the design area and their respective hydraulic reference points, elevations, actual discharge pressures and actual flows. Indicate elevations of hydraulic reference points (nodes). Documentation shall identify each pipe individually and the nodes connected thereto. Indicate for each pipe the diameter, length, flow, velocity, friction loss, number and type fittings, total friction loss in the pipe, equivalent pipe length and Hazen-Williams coefficient.

1.2.2 Sprinkler Coverage

SECTION 21 13 18.00 10 Page 3 automatic water control valve shall cause water to fill the pre-action system piping and be discharged from fused sprinklers.

1.2.4.2 Alarm Functions

Activation of the air-aspirating smoke detection system shall cause the illumination of the respective zone annunciator, and activation of the building fire alarm system and transmission of the alarm to the base-wide fire reporting system.
