About this file
This document includes a July 2021 service report for Dover Air Force Base and a related federal contract opportunity solicitation. The service report provides conductivity measurements and notes for various building loop limits, heating water loops, ice banks, and cooling water loops at Dover AFB. The solicitation seeks a contractor to provide a water treatment service program to control corrosion, slime, and algae in condensers, thermal ice storage systems, closed loop heating and cooling systems, gas-fired heating hot water systems, and water softeners at Dover AFB. The solicitation number is FA449721R0027, issued by the Department of the Air Force Air Mobility Command. The site visit is scheduled for August 17, 2021 at 1:00PM EST. The contractor must furnish all labor, tools, transportation and supervision necessary to perform the water treatment services.
