About Lieber Mechanical LLC
Lieber Mechanical LLC, a small business sole proprietorship based in Yukon, Oklahoma, provides mechanical construction and HVAC infrastructure services to the Federal Aviation Administration exclusively as a prime contractor under total small business set-aside vehicles. The company operates under a primary indefinite delivery contract (IDC) with the FAA valued at $11.9 million, awarded January 9, 2023, and holds no subcontractor relationships across its federal footprint.
Lieber Mechanical's capability portfolio centers on facility mechanical infrastructure — data center cooling systems, rooftop-mounted Computer Room Air Conditioning (CRAC) unit replacement, auxiliary power unit installation, heating and ventilation system upgrades, leak detection and external wall services, and cooling tower blowdown recovery. Representative recent work includes a $1.26 million delivery order (awarded June 6, 2025) for ARB B03 data center cooling under the total small business IDC, a $594.5 thousand order (March 6, 2026) for rooftop CRAC unit replacement at the Mike Monroney Aeronautical Center, and a $122.9 thousand cooling system addition to facility RM107 (September 11, 2025). All work occurs at FAA facilities in Yukon, Oklahoma and Oklahoma City.
Customer concentration is absolute: 100% of awards fund FAA programs across three internal offices. The FAA's Franchise Acquisition Services office dominates with seven awards and $13.9 million combined potential value; FAA Headquarters accounts for three awards and $10.1 million; and the Non-Franchise Acquisition Services office holds four awards and $736 thousand. The company has served the FAA continuously since 2014. Activity has grown modestly — one award in 2022, two in 2023, one in 2024, three in 2025, and three in 2026 — though the combined potential value across all fourteen prime awards stands at $24.8 million against $3.6 million obligated (15% burn rate). Two parent vehicles structure the work: the primary $11.9 million total small business IDC (8 task orders, $2.5 million combined value) and the legacy Monroney Aeronautical Center Mechanical Construction 2017-2022 vehicle (4 task orders, $1.1 million). Five awards with combined potential value of $2.2 million reach ultimate completion within the next twenty-four months, exposing Lieber Mechanical to recompete pressure on the FAA's largest delivery order pipeline. The company's NAICS profile splits between Commercial and Institutional Building Construction (9 awards) and Plumbing, Heating, and Air-Conditioning Contractors (5 awards).
