A. Standard-Pressure Sprinkler Piping: Dry-pipe sprinkler system piping
designed to operate at working pressure 175 psig (1200 kPa) maximum.
1.2 SYSTEM DESCRIPTIONS
A. Dry-Pipe Sprinkler System: Automatic sprinklers are attached to piping
containing compressed air. Opening of sprinklers releases compressed air
and permits water pressure to open dry-pipe valve. Water then flows into
piping and discharges from sprinklers that are open.
1.3 PERFORMANCE REQUIREMENTS

kPa) minimum working pressure.
B. Delegated Design: Design sprinkler system(s) modifications, including
comprehensive engineering analysis by a qualified licensed Fire Sprinkler
Contractor, using performance requirements and design criteria indicated.
C. Sprinkler system design shall be approved by authorities having jurisdiction.
1. Automatic-Sprinkler Piping Design:
a. Modify existing Pipe Schedule System in compliance with pipe sizes
for Ordinary Hazard Pipe Schedule for ITR, electric, and storage
rooms. Use light hazard pipe schedule for offices and corridors.
2. Maximum Protection Area per Sprinkler: Per UL listing.
3. Total Combined Hose-Stream Demand Requirement: According to
NFPA 13.
1.4 ACTION SUBMITTALS
A. Product Data: For each type of product indicated. Provide manufacturer’s
catalog data for each separate piece of equipment which indicates the name
of the manufacturer of each item of equipment, with data highlighted to
indicate model, size, options etc., proposed for installation.
B. Shop Drawings: For dry-pipe sprinkler systems. Include plans, elevations,
sections, details, and attachments to other work. Provide layout drawing of
the complete automatic sprinkler system modifications indicating relationship
of all other items including HVAC equipment, lighting fixtures, structural
members, and all other significant items. Clearly indicate elevations and
pitch of all piping. Complete details and sections as required to clearly define
