Purchase of Precision Filters Parts for 31" M10 tunnel DAS Upgrade

This is a sole-source procurement issued by NASA Shared Services Center for the purchase of specialized precision filter parts required to upgrade the 31-inch Mach 10 tunnel’s Data Acquisition System (DAS) at NASA Langley Research Center in Hampton, Virginia. The acquisition, identified by solicitation number 80NSSC26932960Q, was posted on May 13, 2026, with responses due by May 15, 2026, and is being conducted under FAR Part 12 as a commercial item purchase due to the proprietary, non-interchangeable nature of the components, which are uniquely designed and manufactured by Precision Filters, Inc. The contract requires delivery of four specific items by August 14, 2026: quad bridge and dynamic strain conditioners with 8-pole band-pass filters, 8-channel amplifiers with integrated filters, test adapters for excitation, and replacement fans for the 28000 chassis. No competitive evaluation process is involved; the sole-source justification under FAR 12.102(a) is based on the technical uniqueness of the parts and the absence of alternative suppliers capable of meeting the exact performance and compatibility requirements of the legacy system. The place of performance and delivery is explicitly set at NASA Langley Research Center, with acceptance to occur at that location, and no formal inspection criteria or quality standards are specified beyond adherence to the exact manufacturer part numbers and technical specs provided. The contracting officer is Shanna Patterson of the NASA Shared Services Center in Stennis Space Center, Mississippi, and communications must be submitted via email. The procurement references the NASA FAR Supplement clause 1852.215-84 (Ombudsman) but lacks details on contract value, payment terms, invoicing method, packaging requirements, or any formal contract clauses, representations, certifications, or special conditions beyond the core requirement for the components and their delivery timeline. The NAICS code for this acquisition is 334516, indicating manufacturing of measuring and controlling instruments, and no small business set-aside or socioeconomic certifications are indicated.
