About this file
This document contains a request for proposal and pump submittal example. The Defense Information Systems Agency is seeking proposals to upgrade the condenser water filtration, controls and piping system at its facility in San Antonio, Texas. The goal is to improve reliability, energy use and redundancy in accordance with Department of Defense standards. Specifically, the contractor must enhance the cooling towers, replace piping, adjust the water pump, run temporary chillers for redundancy testing and adjust the water filtration controls. The project concerns only the facility's IT mechanical system and not the overall building system. A site visit is scheduled for March 31st with sessions at 9:00am and 12:30pm Central Time for contractors to better understand the work location and conditions. Questions are due by April 9th at 2:00pm Central Time to mark.e.kraft2.civ@mail.mil. The pump submittal example provides specifications for a model pump to meet the required flow rates, pressures, efficiencies and power needs for the system.
