ATTACHMENT A3- FireSuppressionPlumbing Drawings.pdf

This is a set of bid documents for a federal construction project at Salem VA Medical Center, Building 143, consisting of fire suppression and plumbing design and installation drawings for a surgical suite renovation in four phases.

The project involves comprehensive fire suppression system modifications and new installation of wet-pipe sprinkler systems serving the renovated surgical suite areas and a new generator building. The fire suppression work includes modifications to existing systems, installation of new sprinkler piping and heads, zone control assemblies, backflow preventers, fire department connections, and related accessories. Design criteria follow NFPA 13 standards with varying density requirements based on hazard classification (light hazard at 0.10 GPM/SF, ordinary hazard groups at 0.15-0.20 GPM/SF, and extra hazard at 0.30 GPM/SF). The existing 750 GPM fire pump at 85 PSI serves as the water source. All work must maintain NFPA 13 compliance throughout four construction phases, with temporary protection and interim fire watch procedures required during system disruptions. The plumbing scope includes demolition and installation of domestic hot and cold water lines, sanitary and vent piping, medical gas systems (oxygen, medical air, nitrogen, nitrous oxide, carbon dioxide), and waste anesthesia gas disposal piping. Specific fixture counts and connection details are provided in schedules. All materials and installation methods must comply with applicable codes including IBC 2021, NFPA standards, and VA design manuals. The contractor is responsible for field coordination with other trades, hydraulic calculations, system flushing and testing, commissioning, and provision of operations and maintenance manuals to the owner.
