About the company
Lieber Mechanical LLC, a small business sole proprietorship headquartered in Yukon, Oklahoma, delivers 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 across all 17 awards in its source portfolio as a direct prime with no subcontractor relationships, competing uniformly under total small business set-aside designations on its core indefinite delivery contract and under full-and-open competition on subordinate delivery orders where set-asides are not applied.
Lieber Mechanical's customer base is concentrated entirely within the FAA. The three FAA offices—Franchise Acquisition Services, Non-Franchise Acquisition Services, and Headquarters—account for 100% of recent awards and combined potential value of $27.5 million. Franchise Acquisition Services anchors the relationship with 10 awards worth $16.7 million combined potential value, followed by FAA Headquarters with 3 awards totaling $10.1 million, and Non-Franchise Acquisition Services with 4 awards carrying $736 thousand combined potential value.
Lieber Mechanical holds a $14.5 million indefinite delivery contract awarded January 9, 2023, by FAA Franchise Acquisition Services, running through January 8, 2027, as a total small business set-aside multiple-award vehicle for miscellaneous mechanical construction services including facility alterations, extensions, conversions, modernizations, and new construction at the Mike Monroney Aeronautical Center in Yukon and Oklahoma City. Eleven delivery orders have been placed under this IDIQ, carrying $2.6 million combined potential value. Representative work includes a $1.259 million order (June 6, 2025) for ARB B03 data center cooling, a $594,500 order (March 6, 2026) for rooftop CRAC unit replacement, a $122,900 order (September 11, 2025) for cooling system addition to facility RM107, and a $58,500 order (July 29, 2026) to add HVAC systems and seal air leaks in ILS-109. Lieber Mechanical also operates under a predecessor Monroney Aeronautical Center Mechanical Construction 2017-2022 indefinite delivery contract, which generated four delivery orders totaling $1.1 million combined potential value.
Activity has accelerated from one award in 2022 to six awards in 2026. Seven awards (combined potential value $2.2 million) face ultimate completion inside the next twenty-four months and thus represent near-term recompete exposure. The company's capability portfolio, grounded in NAICS codes for commercial and institutional building construction (12 awards) and plumbing, heating, and air-conditioning contracting (5 awards), centers on data center cooling systems, Computer Room Air Conditioning unit replacement and maintenance, auxiliary power unit installation, heating and ventilation system upgrades, leak detection services, and chiller and control system integration for FAA facility infrastructure modernization at Oklahoma locations.
