About this file
This is a Questions and Answers document for Solicitation W15QKN26QA048 regarding an Industrial Vacuum System procurement, dated March 5, 2026, with a final question submission deadline of March 12, 2026 by 1200 EST. The document provides official clarifications on eight key inquiries from potential offerors.
The procurement requires bidders to supply a vacuum vessel (either Configuration A or B) with a total chamber volume of 2400 cubic feet, which must be provided with a sketch or drawing as part of the proposal. The final pressure requirement is 10 Torr (correcting a typographical error in the SOW that stated 8x10⁻³ Torr), with an evacuation time objective of 30-45 minutes and a threshold of 60 minutes maximum. Pressure vessels must be ASME-rated to withstand pressures between 10 Torr and 350 psi, with identical pressure and temperature ratings for both configurations. The design includes a minimum 15-inch diffuser diameter and a heat exchanger positioned before the pressure vessel to manage operational temperatures. Bidders should note that no P&ID (Piping and Instrumentation Diagram) is provided, and the system will be considered Government Furnished Equipment for a future upgrade with hardware sized accordingly. Both configurations (A and B) require identical pressure and temperature rating specifications, though only one configuration is necessary for the vessel portion of the bid.

SUBJECT: Questions and Answers Regarding Solicitation W15QKN26QA048 -
PROJECT: INDUSTRIAL VACUUM SYSTEM
DATE: March 5, 2026 Below are the official responses to questions submitted regarding the aforementioned solicitation.
Question 1: The target time to reach 10⁻³ Torr in the 2400 cubic feet chamber is not specified.
Could you please confirm the desired evacuation time?
Answer 1: The threshold for evacuation time is 60 minutes, with an objective of 30-45 minutes.
Please note a correction to the Statement of Work (SOW): the final pressure should be 10 Torr, not 10⁻³ Torr.
Question 2: Could you provide a sketch or drawing of the chambers, including whether they are spherical, vertical, or horizontal?
Answer 2: Bidders are required to provide a sketch or drawing with their proposal. Any configuration totaling 2400 cubic feet will be considered. Only one configuration (A or B) is necessary for the vessel portion of the bid.
Question 3: Should the chambers be supplied as part of this procurement, or does your facility already have the required vacuum chambers?
Answer 3: As stated in the SOW, the vacuum vessel (either Configuration A or B) must be supplied by the winning bidder.
Question 4: Is there any additional information or requirements for this project? Is there a P&ID of the desired wind tunnel and vessel configuration?
Answer 4: No P&ID is provided. The system will be considered Government Furnished Equipment (GFE) for a future upgrade, and the hardware will be sized to match accordingly.
Question 5: Is there a list of required connection sizes and ratings for the vessels?
Answer 5: The current design requires a minimum diffuser diameter of 15 inches. The pressure vessels must withstand a pressure range between 10 Torr and 350 psi. Vessels must be ASME-rated for this pressure range and the temperatures specified in the SOW.
Question 6: We spoke with someone in 2024 in regard to this project and our capabilities, and at the time the ultimate vacuum requirement was 10 torr. This SOW now says 8x10^-3 torr. This is a large change in ultimate vacuum and required equipment. I wanted to confirm that the SOW requirement is correct.
Answer 6: The requirement of 8x10⁻³ Torr was a typographical error in the SOW. The correct final pressure requirement is 10 Torr.
Question 7: In our previous conversation, the time frame for vessel evacuation was 30-45 minutes. Is this still the case?
Answer 7: Yes, that is correct. The objective remains 30-45 minutes, with a maximum threshold of 60 minutes.
Question 8: Configuration B mentions a pressure of <350 PSIG and a temperature of 800°F.
Please confirm those are the max rating requirements for the vessels.
Answer 8: The pressure and temperature ratings should be identical for both Configuration A and Configuration B. The design includes a heat exchanger to be placed before the pressure vessel, so the final operational temperature may be lower. The pressure vessels must be rated to withstand a range of pressures between 10 Torr and 350 psi, as the compressors will supply air up to a maximum of 350 PSI.
