Statement of Work Building 154 Chilled Water And Condenser Water Valve Replacement USDA, Ames 08/01/2017

Project Requirements:

Background:

Building 154 is where the existing campus chilled water plant is located. There are currently six chillers located in building 154 (Chillers 3, 4, 5, 6, 7, and 8). All of the chillers have both 14” chilled water supply and 14” return piping connections to them as well as 16” condenser water supply and 16” condenser water returns to them. Each one of these piping connections was originally installed with a butterfly valve. All of these butterfly valves are now leaking by which create issues when trying to isolate a chiller for maintenance or repair while the rest of the chilled water system is in operation.

Scope:

Contractor shall come in and replace existing leaking, butterfly, isolation valves with new butterfly valves during winter time period when NCAH campus chilled water system is drained and deactivated. Butterfly valves to be replaced are on both the inlet and outlet side of both the chilled water and condenser water system connections to the chillers located in Building 154.
