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

This document outlines NASA's requirements for a 30-day noise and vibration monitoring campaign at Stennis Space Center (SSC) to assess the impact of rocket engine testing operations. The selected contractor must design, install, monitor, and remove a network of 73 systems, consisting of 38 sound level monitoring stations and 35 triaxial vibration stations, across 16 specified buildings and the Enterprise Park site. Key deliverables include continuous indoor and outdoor measurements, multi-floor assessments in select buildings, site-wide acoustic and vibration mapping, and a final technical report correlating findings with NASA’s engine test logs. Performance will be evaluated based on strict Technical Performance Measures (TPMs), including a minimum 95% data availability per station, 100% pre-deployment instrument calibration, and at least 90% telemetry uptime for remote health monitoring. The contractor is responsible for completing the installation within five days, maintaining systems, and retrieving all equipment within two weeks of data collection. NASA will support the initiative by providing facility access, safety training, indoor power sources, staging areas, and daily engine test logs. The final report and comprehensive dataset must be delivered within four to six weeks post-retrieval to ensure compliance with NASA’s inspection and acceptance criteria.

NASA/NSSC has issued a sole source synopsis announcing its intent to award a contract to HGC Noise Vibration Acoustics, Inc. for a 30-day noise and vibration monitoring campaign at the Stennis Space Center (SSC). NASA/NSSC will serve as the procuring center for this commercial services acquisition, which falls under NAICS code 541690. While the government intends to proceed on a sole-source basis, interested organizations may submit their capabilities and qualifications in writing by 12:00 p.m. CST on August 12, 2026, to be evaluated for potentially competing the procurement.
