Joint Base Charleston MACC (JB CHS)

The Department of the Air Force Air Mobility Command awarded this Master IDIQ for construction, alteration, repair, and demolition work at Joint Base Charleston on May 15, 2023, with authority to issue orders through May 15, 2028—approximately 21 months of ordering authority remaining. The vehicle carries a combined potential value of $96 million, though all $74.6 million of that total has been obligated across 19 awarded task orders as of January 15, 2026.

Work encompasses new construction, alteration and repair of buildings and structures, roads, grounds and utilities, design-build services from concept through 100 percent design completion, and ancillary material procurement and labor management across multiple simultaneous projects at the base. Recent orders illustrate the scope: dormitory renovation valued at $24.6 million, water distribution system repair, overhead utility system repairs, airfield parking ramp lighting, munitions facility construction, and lightning protection and electrical system repairs on wharf facilities. Task orders are priced on a firm fixed-price basis with durations ranging from months to years; the largest single order (dormitory renovation) runs to February 7, 2028.

The MACC demonstrates strong HUBZone concentration: 74 percent of awarded orders carry HUBZone set-asides, with the remainder split between unrestricted (21 percent) and total small-business (5 percent) designations. Customer funding is dominated by Air Mobility Command (18 orders, $68.2 million potential value) with one order funded by Department of the Air Force generally ($6.4 million).

Competition remains fragmented. Outside Box LLC leads by potential value at $34.8 million across three orders (47 percent of combined value), while A-Plus K&K JV Inc. and Hightower Construction Co Inc. each hold $15 million across seven and six orders respectively. Siler SCF JV LLC accounts for $9.8 million in two orders; Ashford Leebcor Enterprises V, LLC appears once at $2 thousand. This distribution suggests opportunity for new entrants, though Outside Box's concentration warrants attention.

Ordering momentum has declined: the vehicle averaged 5.75 orders annually in 2023–2025 but shows only one award year-to-date through mid-2026, though 85 percent of the ceiling remains unobligated and the ordering period extends well into 2028, suggesting the velocity may reflect timing rather than market closure.

In this IDIQ work vendors can expect will include, but is not limited to, new construction, alteration/repair and/or demolition of buildings and structures, roads, grounds, and utilities. Work may also include design/build from concept to full 100% design. Vendors will furnish all materials, equipment, transportation, and personnel necessary for project requirements and to manage and accomplish multiple, simultaneous projects.
