Tennessee Valley Services Inc.

Tennessee Valley Services Inc., a woman-owned small business based in Killen, Alabama, delivers minor construction and facility maintenance services exclusively to NASA's Marshall Space Flight Center as a prime contractor under total small business set-asides. The firm operates 100% as a prime contractor (75 awards, zero sub-awards) and competes predominantly under small business set-aside vehicles.

Tennessee Valley Services' entire federal footprint concentrates on a single customer: Marshall Space Flight Center accounts for all 75 awards and the combined potential value of $52.7 million. The vendor holds two active IDIQs at Marshall: a $20 million multiple-award IDIQ (80MSFC24DA016, awarded March 26, 2024, through March 25, 2029) set aside for total small businesses, with 17 task orders carrying $4.8 million in combined potential value, and an older IDIQ (80MSFC19D0011) carrying 56 task orders worth $7.9 million in combined potential value. Both vehicles authorize firm fixed-price task orders ranging from $5,000 to $1 million for minor construction, facility maintenance, and building infrastructure work at the Huntsville campus.

Concrete work scope spans HVAC upgrades, electrical installations and modifications, fire protection system design and repair, roof replacements, window and door installations, lightning protection systems, plumbing, demolition, and building renovations across multiple building types. Representative recent delivery orders include a $2.53 million roof replacement for Building 4205 (issued June 17, 2025), a $1.30 million window installation for Building 4249 (issued October 30, 2023), a $915,365 office area modification in Building 4250 (issued April 26, 2023), a $749,017 HVAC system installation (issued November 16, 2023), and a $162,149 wall installation in Building 4260 (issued January 6, 2026). Smaller orders cover cafeteria finish updates, bathroom renovations, electrical disconnects, lightning protection design, and utility modifications.

Activity has grown from six awards in 2022 to fifteen in 2024, though 2025 showed a sharp decline to two awards with only seven in 2026. Nine awards carrying combined potential value of $3.1 million face ultimate completion within the next twenty-four months, creating modest recompete exposure. To date, 24% of combined potential value ($12.5 million) has been obligated across the 75-award portfolio, indicating that most of the vendor's capacity remains in future task order performance or projected work.

Tennessee Valley Services' customer concentration and vehicle reliance create strategic risk: complete dependence on Marshall Space Flight Center and ordering authority through two IDIQs mean competitive displacement at either vehicle or customer level would eliminate the entire prime footprint. The vendor carries no subcontract relationships or diversified customer base to hedge that exposure.
