About this file
This request for proposal is for upgrading the condenser water filtration, controls and piping system at the Defense Information Systems Agency facility in San Antonio, Texas. The contractor will enhance the cooling towers, replace piping, adjust the water pump, run temporary chillers for redundancy testing, and adjust the water filtration controls. The project is working on the IT mechanical system separately from the building mechanical system. A site visit is scheduled for March 31, 2021 with two sessions for contractors to better understand the work requirements. Questions are due by April 9, 2021 to mark.e.kraft2.civ@mail.mil. The Defense Information Systems Agency is the issuing agency.
