The U.S. Army Contracting Command-Redstone is conducting market research through a Request for Information to identify capable vendors for the procurement of a closed-circuit wind tunnel to be installed at the Army Primary Standards Laboratory in Redstone Arsenal, Alabama. This specialized facility is intended for use by USATA Engineers and Technicians to support high-precision calibration activities using a Laser Doppler Velocimetry system, which requires the generation of extremely low air velocities down to 0.15 meters per second with a turbulence intensity under 1 percent. The wind tunnel must feature a 24-inch by 24-inch test section with optical-quality glass sidewalls to accommodate a 532-nanometer, 500-milliwatt argon-ion laser, and include seven sealable instrument ports that accept probes ranging from 4.3 to 15.9 millimeters in diameter. A 3/8-inch Swagelok bulkhead fitting upstream of the test section is required for the introduction of Bis(2-ethylhexyl) subacute seed particles, and the test section must include grooves at approximately 90 percent of its length to allow installation of adjustable nozzle restriction plates. A 15-inch section of the test area located six inches upstream of these plates must be replaceable without compromising the integrity of the wind tunnel circuit. The system must have a centrifugal fan with vibration isolation, driven by a variable-frequency drive controlled exclusively through LabVIEW software with no wireless or internet connectivity, and must operate at a maximum speed of approximately 50 meters per second while maintaining the specified turbulence criteria. The entire system, including all associated components, must not exceed 32 feet in length, 8 feet in width, or 7.5 feet in height.

Proposals must be submitted directly via email to designated points of contact and are evaluated in two phases: a solution brief phase and a presentation phase. Pass/fail gates require offerors to possess a valid Unique Entity ID (UEI), be registered in the System for Award Management (SAM), and enroll in the Wide Area Work Flow invoicing system; failure to meet any of these renders a proposal ineligible. Evaluation criteria focus on responsiveness to the AoI, technical merit, innovation, affordability, IP restrictions, and the reasonableness of proposed timing and cost estimates. All submissions must be unclassified and may not be marked confidential; any Controlled Unclassified Information (CUI) must be handled in compliance with 32 CFR Part 2002. Offerors must also comply with the Procurement Integrity Act, be free from suspension or debarment, and for certain AoIs like the TIGER Hackathon, must affirm adherence to the Trade Agreements Act and Buy American Act while explicitly denying reliance on adversarial foreign nations for critical components. Technical proposals must include detailed workflows, staffing plans, deliverables with timelines, and full technical disclosures, while price proposals must provide labor categories, hours, rates, and material costs sufficient for government analysis. Contract awards will be contingent on favorable evaluation and available funding, with no pre-determined contract ceiling specified.
