1.2 SYSTEM DESCRIPTION

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

SECTION 21 13 13.00 10 Page 2 sprinkler discharge pattern and coverage. Provide wet pipe sprinkler system in areas indicated on the drawings. Except as modified herein, the system shall be designed and installed in accordance with NFPA 13 and UFC 3-600-01. Pipe sizes are indicated on drawings. 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 is based on hydraulic calculations, and the other provisions specified herein. Once complete, the design shall provide total sprinkler protection of Group A Plastic commodities stored on open shelves within the warehouse storage area.

In-rack sprinklers are not required when utilizing ESFR sprinklers.

Dry-type sprinklers shall protect the loading dock areas.

Demolish the existing sprinkler system in its entirety, except for the Administrative Annex sprinkler zone and in-rack sprinkler piping. The existing in-rack sprinklers shall be removed. Phasing of the sprinkler work shall be coordinated with the government and performed in accordance with Division 1. A fire watch shall be required in areas that are unprotected by the sprinkler system. Fire watch shall comply with the requirements in NFPA 25.

1.2.1 Hydraulic Design

Hydraulic design information for each sprinkler zone is noted on the Drawings. The minimum pipe size for branch lines in gridded systems shall be 2-1/2 inch. Water velocity in the piping shall not exceed 20 ft/s.

1.2.1.1 Hose Demand

An allowance for exterior hose streams shall be applied to the sprinkler system demand at the fire hydrant closest to the point where the water service enters the building. The hose stream allowance based on the various hazards is noted on the Drawings. An allowance for interior hose stations is unnecessary since there are no interior hose valves, as directed by DLA

AHJ.

1.2.1.2 Basis for Calculations

The design of the system shall be based upon a water supply with a static pressure of 100 psi, and a flow of 4,000 gpm at a residual pressure of 99 psi at the existing fire pump discharge. Water supply shall be presumed available at the point of connection to existing. Hydraulic calculations shall be based upon the Hazen-Williams formula with a "C" value of 120 for steel piping and 100 for existing underground piping.

1.2.1.3 Hydraulic Calculations

Submit hydraulic calculations, including a drawing showing hydraulic reference points and pipe segments and as outlined 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. Software that uses k-factors for typical branch lines is not acceptable. Calculations shall be based on the water supply data shown on the drawings to substantiate that the design area used in the calculations is the most demanding hydraulically. Water supply curves and system requirements shall be plotted on semi-logarithmic graph paper so as to present a summary of the complete hydraulic calculation. Provide a

SECTION 21 13 13.00 10 Page 3 summary sheet listing sprinklers in the design area and their respective hydraulic reference points, elevations, actual discharge pressures and actual flows. Elevations of hydraulic reference points (nodes) shall be indicated. Documentation shall identify each pipe individually and the nodes connected thereto. Indicate the diameter, length, flow, velocity, friction loss, number and type fittings, total friction loss in the pipe, equivalent pipe length and Hazen-Williams coefficient for each pipe. For gridded systems, calculations shall show peaking of demand area friction loss to verify that the hydraulically most demanding area is being used.

Also for gridded systems, a flow diagram indicating the quantity and direction of flows shall be included. A drawing showing hydraulic reference points (nodes) and pipe designations used in the calculations shall be included and shall be independent of shop drawings. Provide 10 psi safety factor, as required by the DLA AHJ.

1.2.2 Sprinkler Coverage

Sprinklers shall be uniformly spaced on branch lines. In buildings protected by automatic sprinklers, sprinklers shall provide coverage throughout 100 percent of the building. This includes, but is not limited to, telephone rooms, electrical equipment rooms, boiler rooms, switchgear rooms, transformer rooms, and other electrical and mechanical spaces.

Coverage per sprinkler shall be in accordance with NFPA 13, but shall not exceed the requirements listed in NFPA 13.

1.3 SUBMITTALS

Government approval is required for submittals with a "G" designation;

submittals not having a "G" designation are for information only. When used, a designation following the "G" and/or the "G/AE" designation identifies the office that will review the submittal for the Government.
