About this file
This document is a Request for Information (RFI) for HVAC Cooling Tower Chemical Sampling and Treatment services at Scott Air Force Base, 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 (56 chilled and 68 hot), and 27 coupon racks. The contract will be managed by the Department of the Air Force Air Mobility Command, combining two previous contracts (FA440725P0002 and FA440724P0001).
Key details include specific technical requirements such as using inhibited propylene glycol in all chilled water and 20 heating closed loop systems, and chemical treatment specifications. Pricing will be based on cost per 1,000 gallons of make-up water, with flexibility for vendors to propose different total gallons and chemical concentrations. The RFI includes 14 questions and responses covering incumbent information, water system volumes, chemical treatment requirements, and clarifications on technical specifications. Notably, the site does not require Cybersecurity Maturity Model Certification (CMMC) for handling DoD data, and the solicitation number is FA440725QJC02.

| 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 |
