Attachment J-1601000-12 Water Assets.xlsx

This is an asset inventory attachment listing potable water distribution system components and chilled water utility system components at the Naval Research Laboratory (NRL) facility in Washington, DC.

The potable water assets are organized by service area zones (EZ1, NZ1, NZ2, SZ1) and include approximately 267 system valves (gate valves ranging from 3 to 12 inches, post indicator valves, and hydrant valves), 89 dry-barrel fire hydrants, and piping infrastructure totaling approximately 36,421 linear feet across all zones. Installation dates for most valves range from 1955 to 2021, with the majority installed between 1980 and 1991. The chilled water system assets include 35 distribution and return gate valves (ranging from 3 to 20 inches) organized across three service area zones (NZ1, NZ2, SZ1) with associated piping totaling approximately 12,978 linear feet. All chilled water system components were installed in 1990, except for one pipe section installed in 2021. These asset listings appear to support the facility management and utilities maintenance requirements outlined in the related Naval Research Laboratory Facility Support Services (FSS) contract solicitation (N4008027R1001), which covers an eight-year performance period beginning February 17, 2028, with a small business set-aside designation.
