About this file
This is a Questions and Answers (Q&A) log for federal contract solicitation FA449726Q0031, a recurring water treatment services requirement at Dover Air Force Base.
The contract is not a new requirement; Coastline Ltd. is the incumbent contractor performing under FA449722C0003, with an initial awarded value of $430,900.00 and a current total contract value of $462,890.00 following modifications. The solicitation covers water treatment services for approximately 126 closed-loop systems and 5 water softeners at the installation. All systems are closed-loop with no cooling towers; however, ice thermal storage tanks require testing and treatment on the bath side. Current glycol type is propylene at 20% to 40% concentration, with aluminum boilers present in Buildings 922, 605, and 520. The contractor must maintain propylene concentrations between 25% to 35% in chilled water and heating loops, with specific building requirements to be determined during a mandatory site visit. The contractor is responsible for purchasing all chemicals, including corrosion inhibitor chemicals required for proper corrosion protection and Bellacide 355 biocide for ice thermal storage systems. Glycol replacement and addition will be handled through separate Contract Line Items (CLINs) for labor and material listed in the quote schedule. Licensed personnel must be on staff prior to contract performance, though licenses are not required with initial quotes; resumes for required personnel must be submitted prior to award. The contractor must provide Safety Data Sheets (SDS) for all chemicals to the Contracting Officer and Base Environmental Flight after award but prior to introducing chemicals on-site. No bonds are required, and the government will provide escorts if needed for restricted areas. Contractor personnel will receive badges for mechanical room access; mechanical rooms are always locked but key access will be provided. The site visit is mandatory and detailed in Amendment 0003. The government owns all water treatment equipment but is unable to provide an equipment list or historical chemical usage data at this time.
