LHH Construction Services, Inc.

LHH Construction Services, Inc., a Service Disabled Veteran Owned Business (SDVOSB) and Subchapter S corporation headquartered in Florence, Alabama, holds a Total Small Business set-aside multiple-award IDIQ with the Air Force Test Center for civil engineering building and utilities mechanical services, with all work performed to date at Arnold Air Force Base in Tullahoma, Tennessee. The vendor operates exclusively as a prime contractor; the footprint consists of a single $99 million IDIQ awarded August 15, 2023, and two delivery orders issued against it totaling approximately $980 thousand in obligated value.

LHH's capability portfolio centers on mechanical installation, minor construction, and infrastructure sustainment with specialized focus on HVAC systems maintenance and replacement. The IDIQ covers mechanical installation, minor construction, infrastructure sustainment, and maintenance and repair of heating, ventilation, and air-conditioning systems under NAICS codes 238210 (Electrical Contractors), 238220 (Plumbing, Heating, and Air-Conditioning Contractors), and 237310 (Highway, Street, and Bridge Construction). Representative work includes a March 5, 2026 delivery order to replace the total HVAC system in Building 320 at a ceiling value of $975 thousand with completion targeted for November 26, 2026, and an August 15, 2023 post-award conference task order priced at $4,500. The original solicitation anticipated task orders ranging from $50 thousand to $15 million, with the agency planning to award approximately three contracts under the multiple-award vehicle.

Customer concentration is entirely with the Air Force. The Department of the Air Force Materiel Command Test Center accounts for the $99 million IDIQ and one delivery order; the Department of the Air Force proper placed the March 2026 HVAC replacement order. One award (the Building 320 HVAC replacement) faces ultimate completion within the next twenty-four months, representing $975 thousand in near-term recompete exposure. Combined obligated dollars across all awards total $980 thousand, or approximately 1% of the IDIQ ceiling, indicating early-stage task-order draw-down against a vehicle with substantial remaining capacity through August 2028.
