About the company
Technical Assurance, Inc., operates exclusively as a subcontractor to Honeywell Federal Manufacturing & Technologies, LLC on the Department of Energy National Nuclear Security Administration's National Security Campus management and operation contract (DE-NA0002839), a construction IDIQ. The vendor is a for-profit Subchapter S corporation based in Willoughby, Ohio, with no prime contract awards in the source data and 100% of recent activity routed through Honeywell as the prime contractor.
Technical Assurance's federal footprint is entirely concentrated on a single customer and a single parent vehicle. All eleven awards in the source data span September 2024 through May 2026 and flow from the NNSA's National Security Campus IDIQ under Honeywell's prime management. The combined potential value across all sub-awards is $3.52 billion, reflecting the scale of the underlying campus operations contract rather than Technical Assurance's discrete task-order values. The vendor's category concentration is exclusively in Facilities Support Services (NAICS 561210), indicating delivery of facilities management, maintenance, or related support work on the Kansas campus.
Activity has accelerated year over year. Technical Assurance received two sub-awards in 2024, six in 2025, and three through May 2026, with the most recent award dated May 26, 2026. The vendor operates in a tightly scoped teaming arrangement — Honeywell Federal Manufacturing & Technologies is the sole prime contractor in the source data, and Technical Assurance functions as a named subcontractor on successive task orders under the same parent IDIQ rather than across multiple primes or vehicles.
Service Contract Inventory reporting captures only one record for the vendor, covering FY2024 as a named subcontractor with 43.8 FTEs delivered. SCI data is a partial view and excludes classified contracts, goods, and non-federal revenue; the $3.52 billion obligated across the eleven sub-awards likely reflects a much larger operational footprint than SCI's $150,000 threshold captures, particularly on construction and facilities work that may fall outside SCI's service-contract scope or operate under classified reporting restrictions. The single SCI record does not support a durable characterization of the vendor's pricing posture, workforce trends, or sub-engagement strategy across the broader federal portfolio.
