SECTION 033000 - CAST-IN-PLACE CONCRETE

Sludge Treatment Project Engineered Container Retrieval and Transfer System December 2011
SECTION 211313 – WET-PIPE SPRINKLER SYSTEM
PART 1 - GENERAL
This CSP Section covers the requirements for the design and installation of the Modified K West Annex
Building automatic sprinkler system, as Part of the K-West Basin Sludge Removal Project.
1.1 RELATED DOCUMENTS
Drawings and general provisions of the Contract, including General and Supplementary Conditions
and Division 01 Specification Sections, apply to this Section.
1.2 SUMMARY
A. Scope of Work: Provide design, shop drawings, project record drawings (as-built), equipment,
fabrication, labor, transportation and supervision necessary to install, flush, test and place
into service complete, hydraulically designed automatic wet-pipe sprinkler system. Furnish
piping offsets, fittings, and any other accessories as required to provide a complete
installation and to eliminate interference with other construction. Install sprinklers over and
under ducts, piping and platforms, including the mezzanine, when such equipment can
negatively affect or disrupt the sprinkler discharge pattern and coverage. Provide wet-pipe
sprinkler system in all areas of the building. Except as modified herein, design and install
the system in accordance with NFPA 13, DOE 1066-99, and DOE FPHB-HC. 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.
Pipe sizes shall be determined by hydraulic calculation. Coordinate installation with other
disciplines.
B. Hydraulic Design. Hydraulically design the system to discharge a minimum density of 0.2 gpm
per square foot over the hydraulically most demanding 1,500 square feet of floor area.
Provide hydraulic calculations in accordance with the Area/Density Method of NFPA 13.
1. Hose Demand. Add an allowance for exterior hose streams of 250 gpm to the sprinkler
system demand at the fire hydrant shown on the drawings closest to the point where
the water service enters the building
2. Basis for Calculations. Base the design of the system upon a water supply with a static
pressure of 125 psi, and a flow of 1908 gpm at a residual pressure of 80 psi, based on
March 2011 flow tests through the pressure-reducing valve for the raw water crossconnection.
Water supply shall be presumed available at the point of connection to
existing water supply between gate valves FP-GV-65 and FP-GV-104. Base hydraulic
calculations upon the Hazen-Williams formula with a "C" value of 120 for galvanized
or black steel piping, 140 for new cement-lined ductile-iron piping, 150 for
underground PVC piping, and 100 for existing underground piping. The sprinkler
system demand, with hose stream allowance, shall be at least 10%, but no less than 10
psi, below the supply curve.
a. Outline hydraulic calculations as in NFPA 13, except that calculations shall be
performed by computer using software intended specifically for fire protection
