ADC Engineering Inc.

ADC Engineering Inc., a for-profit Subchapter S corporation headquartered in Hanahan, South Carolina, delivers architectural-engineering services and construction inspection work to the Department of Defense as a prime contractor (99% of recent awards) under small business set-asides and full-and-open competitions. The firm specializes in military airfield infrastructure, pavement design and repair, facilities engineering, and Title II construction oversight—work that sits primarily under NAICS 541330 (Engineering Services) and PSC codes for architect-engineer general services and airfield infrastructure.

ADC Engineering's customer base concentrates heavily with the Air Force. The top five funding agencies by award count account for 79% of recent awards, led by the Department of the Air Force Air Mobility Command (77 awards, $46.2 million combined potential value), the Marine Corps (12 awards, $497 thousand), the Navy (11 awards, including 7 from Naval Facilities Engineering Command), and the Army Corps of Engineers Engineering District Omaha (5 awards, $11.6 million). However, the potential-value ranking reveals a structural divergence: the Air Force Civil Engineer Center's single award for the AE NEXT 2021 Pool 1 contract vehicle carries a $2.01 billion ceiling, dominating the total combined potential value of $2.09 billion across all 141 awards. This IDIQ represents the company's largest vehicle position but masks the true operating footprint, which is anchored by sustained task-order work at Joint Base Charleston under Air Mobility Command.

ADC Engineering holds four primary IDIQ vehicles. The $2 billion AE NEXT 2021 Pool 1 contract (Air Force Civil Engineer Center, completed July 2031) provides Title I, Title II, and other architect-engineer services for airfield infrastructure across Air Force installations; two task orders placed against it total $12.9 million (an $11.02 million runway repair project at Travis Air Force Base and a $1.87 million parking ramp repair task). A $19.5 million IDIQ with Air Mobility Command (completed May 2027) has generated 39 task orders valued at $7.6 million combined, spanning design services for dormitory renovations, airfield pavement repairs in multiple areas, specialty facilities (munitions, hazardous materials handling), construction inspection and quality assurance, stormwater studies, and dock repairs—work concentrated at Joint Base Charleston. A $10 million Indefinite Delivery Contract with the Army Corps of Engineers Engineering District Omaha (completed August 2028), designated a Total Small Business set-aside, has generated 4 delivery orders totaling $4.1 million for military airfield projects including unified soil airfield recycling pavement (USAR PAVER) work, electrical assessments, and general engineering support. A $20 million Air National Guard architect-engineer services contract (completed August 2029) for Horizontal Region 2 (southern and central states) was awarded in August 2024 as a multiple-award, total small business set-aside.

Recent activity shows declining volume: 12 awards in 2022, 9 in 2023, 14 in 2024, 7 in 2025, and 1 through May 2026. Only four awards totaling $2.1 million in combined potential value face ultimate completion within the next twenty-four months, presenting a modest recompete cliff. ADC Engineering competes predominantly under total small business set-asides on the Air Force and National Guard vehicles and under full-and-open competitions on the larger AE NEXT 2021 Pool 1 and selected Army Corps work. The firm operates as a prime on virtually all awards; SCI reporting captures only one record (FY2022), a named subcontractor position, reflecting negligible sub engagement in the tracked dataset. Two sub-award records show ADC Engineering delivering architect-engineer design services to HDR Engineering, Inc. of the Carolinas on Navy fitness center and Navy engineering projects (April 2025 and June 2022).

Capability work centers on airfield pavement design and repair, runway rehabilitation, Title II construction inspection and quality assurance, facilities design for military buildings (dormitories, munitions facilities, hazardous materials handling, child development centers, dock facilities), utility system assessments (stormwater, wastewater treatment, electrical, lift stations), and structural/building envelope evaluations. Representative task orders include an $11.02 million Title II construction services contract for runway repair at Travis Air Force Base (completed May 2026), a $936,465.94 delivery order for runway pavement design at Joint Base Charleston, an $818,582.88 dormitory design project at Joint Base Charleston, a $957,090.74 USAR PAVER airfield project, and a $22,800 small business set-aside purchase order from the Coast Guard for structural and building envelope evaluation of the Rice Mill Building at USCG Base Charleston (awarded May 2026, completed June 2026). Place of performance spans Joint Base Charleston and outlying properties, Travis Air Force Base, military installations nationwide, and federal facilities in Arizona, Idaho, and Nebraska, reflecting broad geographic scope across the DoD footprint.
