About this file
This document is a Request for Information (RFI) for HVAC Cooling Tower Chemical Sampling and Treatment services at Scott AFB, Illinois. The RFI covers a contract opportunity involving water/chemical monitoring, sampling, and treatment for 13 cooling towers across 8 facilities, 124 closed loop systems, and 27 coupon racks. The solicitation, issued by the Department of the Air Force Air Mobility Command, seeks a contractor to provide labor, tools, chemicals, and equipment for comprehensive HVAC system maintenance.
Key details include chemical treatment specifications such as requirements for inhibited propylene glycol in chilled water and heating closed loop systems, liquid oxidizing biocide treatments, and pricing based on chemical concentration per 1,000 gallons of makeup water. The RFI documents multiple vendor questions and government responses, clarifying technical specifications, chemical treatment expectations, and confirming that the new contract combines two previous contracts (FA440725P0002 and FA440724P0001). The solicitation does not require Cybersecurity Maturity Model Certification (CMMC) and allows for potential contract modifications to adjust for chemical usage variations.

| Requests For Information (RFIs) - HVAC Cooling Towers & Water Sampling | |||||
| RFI # | Date Recv'd | Date Sent to Customer/Technical Expert | RFI | Response | Date Answered |
| 1 | 3-Sep-25 | N/A | Who is the current or most recent incumbent contractor providing these services? | This contract combines two previous contracts FA440725P0002 and FA440724P0001. This is all the information we can give at this time. | 8-Sep-25 |
| 2 | 3-Sep-25 | N/A | What was the contract number and total dollar value (base + option years, if applicable) of the previous award? | This contract combines two previous contracts FA440725P0002 and FA440724P0001. This is all the information we can give at this time. | 8-Sep-25 |
| 3 | 3-Sep-25 | N/A | Is there any publicly available record (e.g., FPDS, USAspending.gov, or published award notice) where we can review the prior contract details? | This contract combines two previous contracts FA440725P0002 and FA440724P0001. This is all the information we can give at this time. | 8-Sep-25 |
| 4 | 3-Sep-25 | N/A | Has the scope of services changed significantly from the previous award, or is this a direct follow-on? | This contract combines two previous contracts FA440725P0002 and FA440724P0001. Quantities and number of facilities have changed. | 8-Sep-25 |
| 5 | 4-Sep-25 | 4-Sep-25 | What is the total annual M/U amount (in gallons) to the site’s (13) cooling tower systems? | We do not track total annual M/U water usage. See attachment 2 for July/August readings. | 8-Sep-25 |
| 6 | 4-Sep-25 | 4-Sep-25 | What is the estimated volume (in gallons) of the (2) “common sumps” at B1700 and B1900 cooling tower systems? | Estimated capacity of B1900 CT basin = 9575 gal, B1700 is equipped with a dual tower configuration consisting of two basins linked via an equalizer line = unknown. | 8-Sep-25 |
| 7 | 4-Sep-25 | 4-Sep-25 | SOW Section 5.1 – confirm how many closed loop systems require the inhibited propylene glycol….all loops or just certain CW loop systems? | Inhibited propylene glycol is required in all chilled water closed loops systems plus 20 heating closed loop systems. | 8-Sep-25 |
| 8 | 4-Sep-25 | 4-Sep-25 | Can the Government clarify the requirement for liquid oxidizing biocide (not chlorine) and what products they consider to be acceptable? I specifically would like to know if the Government considers sodium hypochlorite and liquid chlorine to be the same. Sodium hypochlorite is far less expensive and may not be as effective compared to bromine based product. | We will accept an equivalent product of what is currently being used, AM68 (See attachment 1) | 8-Sep-25 |
| 9 | 4-Sep-25 | 4-Sep-25 | Can the Government verify that chemical cost should be based on the cost per 1,000 gallons of make up water for the Inhibitor, Liquid Oxidizing Biocide, and Non-oxidizing biocide? | Yes, true statement. | 8-Sep-25 |
| 10 | 4-Sep-25 | 4-Sep-25 | Can the pricing be based on the concentration of chemicals delivered vs solely gallons to account for differences between proposals? | Yes, but it should equal a cost per 1,000 gal of make-up water and the equation is spelled out in your proposal. | 8-Sep-25 |
| 11 | 4-Sep-25 | 4-Sep-25 | Can we submit a proposal that has different Total Gallons per year to account for the needs of the base and the concentration of chemicals? | Yes, as long as the equation is spelled out in your proposal. The intent is to establish a base price for product. | 8-Sep-25 |
| 12 | 5-Sep-25 | 5-Sep-25 | I was working with our operations department and since this is a DOD but a sub tier and air mobility command does this site require Cybersecurity Maturity Model Certification (CMMC) for handling DoD data. | No, does not | 8-Sep-25 |
| 13 | 3-Sep-25 | 9-Sep-25 | During our site visit I asked the question about Inhibited Glycol in the "Statement of Work" page 4, 5.1.1 versus the Uninhibited Glycol in the "Request for Quotation page 2 Item #0009. And it was confirmed by Mr. Brian Short that it should be "Inhibited Glycol". I just wanted to confirm that it's "Inhibited Glycol" and that all the vendors remember this change. | Yes, true statement. Pricing Sheet and RFQ have been updated. | 9-Sep-25 |
| 14 | 11-Sep-25 | 11-Sep-25 | Are the quantities listed in the CLIN structure (e.g., 3,000 gallons corrosion inhibitor, 1,000 gallons oxidizer, 1,000 gallons non-oxidizing biocide, 500 gallons nitrite, 3,000 gallons glycol) the annual estimated usage volumes that should be priced by all vendors | Yes, they are estimates | 11-Sep-25 |
| 15 | 11-Sep-25 | 11-Sep-25 | If not, will the Government provide historical annual makeup water volumes or historical annual chemical usage data so vendors can calculate the Base Year amounts consistently? | See RFI #5 | 11-Sep-25 |
| 16 | 11-Sep-25 | 11-Sep-25 | If actual consumption differs from these estimates, how does the Government intend to handle overages or underruns (e.g., adjustment mechanisms, re-measurement, or firm-fixed pricing regardless of actual usage)? | The government handles this by performing modifications to adjust accordingly for overages and underruns | 11-Sep-25 |
