Z1DA--554-26-106 Replace DW Valves.

OBJECTIVE The Department of Veterans Affairs has a requirement to install valves on water supply lines to enable individual building isolation from the campus water supply at the Rocky Mountain Regional VA Medical Center. Facility Management Services has identified approximately 30 valves on domestic cold water, domestic hot water, and domestic hot water return that require valve installation or valve replacement. The intent of this contract is to install isolation shutoff valves on the domestic cold water (DCW), domestic hot water (DHW), and domestic hot water recirculation (DHWR) pipes at key points to allow facilities maintenance to control water flow to individual buildings. STATEMENT OF WORK In phase 1, the contractor shall: For Building A: Coordinate an 8 hour water shutoff with the COR. This shutdown will likely be scheduled weekday-overnight or weekend-daytime. The DCW/DHW/DHWR shutoffs shall be accomplished using dual ice plugs on each pipeline. The contractor shall position the ice plugs such that a mid-section of pipe can be removed and replaced with a pre-built pipe section that includes a shutoff valve. Ensure the pre-built section and installation effort are conducted at an appropriate cleanliness level for domestic water supply. Install the pre-built pipe section and utilize pipe connections that are grooved coupling or flange as appropriate for the use-case and installation scenario. Re-insulate installed pipe sections. Pipe, valve, and connection/coupler material and sizes shall be appropriate for the use-case and installation scenario. For Building E: Coordinate an 8 hour water shutoff with the COR. This shutdown will likely be scheduled weekday-overnight or weekend-daytime. The DCW/DHW/DHWR shutoffs shall be accomplished using dual ice plugs on each pipeline. The contractor shall position the ice plugs such that a mid-section of pipe can be removed and replaced with a pre-built pipe section that includes a shutoff valve. Ensure the pre-built section and installation effort are conducted at an appropriate cleanliness level for domestic water supply. Install the pre-built pipe section and utilize pipe connections that are grooved coupling or flange as appropriate for the use-case and installation scenario. Re-insulate installed pipe sections. Pipe, valve, and connection/coupler material and sizes shall be appropriate for the use-case and installation scenario. For Building G: Coordinate an 8 hour water shutoff with the COR. This shutdown will likely be scheduled on a Sunday. The DCW/DHW/DHWR shutoffs shall be accomplished using dual ice plugs on each pipeline. The contractor shall position the ice plugs such that a mid-section of pipe can be removed and replaced with a pre-built pipe section that includes a shutoff valve. Ensure the pre-built section and installation effort are conducted at an appropriate cleanliness level for domestic water supply. Install the pre-built pipe section and utilize pipe connections that are grooved coupling or flange as appropriate for the use-case and installation scenario. Re-insulate installed pipe sections. Pipe, valve, and connection/coupler material and sizes shall be appropriate for the use-case and installation scenario. For Building D+F: Coordinate an 8 hour water shutoff with the COR. This shutdown shall be a double install with two crews to accomplish a shutdown and valve install happening simultaneously and will likely be scheduled weekday-overnight or weekend-daytime. The DCW/DHW/DHWR shutoffs shall be accomplished using dual ice plugs on each pipeline. The contractor shall position the ice plugs such that a mid-section of pipe can be removed and replaced with a pre-built pipe section that includes a shutoff valve. Ensure the pre-built section and installation effort are conducted at an appropriate cleanliness level for domestic water supply. Install the pre-built pipe section and utilize pipe connections that are grooved coupling or flange as appropriate for the use-case and installation scenario. Re-insulate installed pipe sections. Pipe, valve, and connection/coupler material and sizes shall be appropriate for the use-case and installation scenario. For Building B: Coordinate an 8 hour water shutoff with the COR. This shutdown will likely be scheduled overnight. The DCW/DHW/DHWR shutoffs shall be accomplished using dual ice plugs on each pipeline. The contractor shall position the ice plugs such that a mid-section of pipe can be removed and replaced with a pre-built pipe section that includes a shutoff valve. Ensure the pre-built section and installation effort are conducted at an appropriate cleanliness level for domestic water supply. Install the pre-built pipe section and utilize pipe connections that are grooved coupling or flange as appropriate for the use-case and installation scenario. Re-insulate installed pipe sections. Pipe, valve, and connection/coupler material and sizes shall be appropriate for the use-case and installation scenari
