30 Day noise and vibration monitoring campaign at Stennis Space Center (SSC).

NASA/NSSC has issued a sole source award to HGC NOISE VIBRATION ACOUSTICS, INC. for a 30-day noise and vibration monitoring campaign at Stennis Space Center in Mississippi, under solicitation number 80NSSC26935569Q, with a response deadline of August 12, 2026. The contract, issued under FAR 12.102(a) and NASA FAR Supplement Clause 1852.215-84, is a non-competitive procurement based on the unique capabilities of the contractor and does not involve a request for quotes or pricing data. The scope includes deploying 73 instrumentation systems—38 sound level monitors and 35 triaxial vibration sensors—across 16 indoor facilities including multi-floor buildings B1111, B1021, and B8000, as well as one outdoor site at New Enterprise Park, with full installation required within five days and complete retrieval within two weeks after monitoring ends. All equipment must be calibrated to manufacturer specifications prior to deployment, with continuous telemetry uptime of at least 90%, data loss limited to less than 5%, and data completeness maintained above 95%. Deliverables include a deployment summary, mid-campaign status update, raw and processed datasets, noise and vibration distribution maps, event-aligned test summaries synced with NASA engine logs, and a final technical report in PDF and native formats accompanied by a formal briefing to NASA personnel, due within 4–6 weeks after retrieval. The contractor must comply with NASA safety protocols, complete mandatory safety orientation, and adhere to site access controls including escorted entry and PPE requirements, with no security clearances needed. All instrumentation must be fully removed from site, with no equipment left behind, and complete deployment logs tracking sensor serial numbers and mounting locations are required. There are no set-asides, no pricing information provided, no specific packaging or labeling standards outside of traceability, no applicable MIL-STDs, and no contractual options or renewal terms. Evaluation is based on strict compliance with quantitative performance thresholds without numerical weighting or adjectival ratings, and inspection and acceptance are conducted by NASA at the installation sites. All correspondence must reference the notice ID in the subject line, and submissions are sent directly to the designated point of contact, Lindsey McLellan and Karen Artis, with no electronic portal used.
