This Performance Work Statement (PWS) details the requirements for a contractor to provide an industrial water treatment service program for high-volume HVAC and heating systems at Dover Air Force Base (DAFB) in Delaware. The primary objective is to control corrosion, slime, algae, and scale in various facility systems, including closed-loop heating and cooling systems, thermal ice storage systems, gas-fired hot water systems, and water softeners. The contractor must provide qualified technicians with at least five years of experience, including a staff chemical engineer, to perform monthly on-site testing, water analysis, and chemical adjustments. Key treatment programs include utilizing molybdate combinations and propylene glycol for closed loops, solar salts for water softeners, and biocides for glycol ice banks. No bulk chemical storage is permitted on-site. Contractors must strictly comply with DAFB environmental, safety, and security protocols. This includes securing hazardous materials (HAZMAT) authorizations, conducting monthly reporting, and completing mandatory Antiterrorism and Operational Security (OPSEC) training. Additionally, personnel must obtain base badges, undergo criminal background checks, and secure airfield driver's licenses if operating on the flight line. Performance is monitored through a Service Summary requiring 100% monthly testing compliance, rapid emergency response times, and the delivery of accurate service reports within five business days of month-end.

This document is a Question and Answer (Q&A) log for solicitation FA449726Q0031, providing clarifications to vendors regarding water conditioner and cooling system maintenance. The government clarified that the existing water conditioners treat air handlers and computer room air conditioning (CRAC) units, with a winter water flow rate of approximately 1,000 gallons per week and less than half of that in the summer. The government does not plan to replace or increase the capacity of the existing water conditioners. If additional units are deemed necessary in the future, the contract will be modified accordingly. Furthermore, the government confirmed that the Performance Work Statement (PWS) will be updated to reflect the correct total number of active water conditioners, as some of the previously identified units are no longer in use and will remain in place. The PWS will also be updated to include new systems at Building 206. Finally, the government identified the manufacturer of the glycol ice bank as CALMAC, though no model number is available.
