Air Force reservists who train to care for patients on military flights will get a building of their own at Joint Base Lindsey Graham, formerly Joint Base Charleston.

The Army Corps of Engineers’ Louisville District awarded Alexandra Construction Inc. of Newton Upper Falls, Massachusetts, a firm-fixed-price contract to build a training building in Charleston, according to the Pentagon’s Sept. 30 contract announcement. The award obligated $20,498,000 in fiscal 2026 military construction money. Its total face value is $21,973,000.

The Pentagon listed Alexandra as a small business. Work is to be finished by Dec. 21, 2029.

Alexandra’s bid of $21,973,000 was the lowest of five opened Aug. 27 and came in under a government estimate of $28,336,968, according to bid opening results the Corps posted on SAM.gov, the federal contracting website. Those results also listed an evaluated bid price of $24,170,300 for Alexandra and labeled David Boland Inc. of Titusville, Florida, whose bid and evaluated price were both $22,132,000, the apparent low bidder.

The building is a 23,701-square-foot training facility for the 315th Airlift Wing’s Aeromedical Evacuation Squadron, according to the Corps’ notices. Plans call for classrooms and training rooms, an auditorium, an open administrative area, a conference room, private offices, a lactation room, and restrooms with lockers.

The building will sit on deep pile foundations and have brick veneer, reinforced masonry walls, a standing seam metal roof and an elevator, the Corps said.

The Corps had estimated the project at $25 million to $100 million in a May notice. The solicitation listed the site as Joint Base Charleston, the base’s name before it was renamed for the late U.S. Sen. Lindsey Graham on Aug. 10.

The 315th Airlift Wing is an Air Force Reserve wing at the base. Its aeromedical evacuation crews are trained to provide medical care in flight while moving patients to higher levels of treatment, the wing says. In January, squadron members practiced patient loading aboard a C-130J Super Hercules as they prepared for an overseas deployment.

“They’re not just looking at slides or completing computer-based training,” Col. Rosa M. Ramos, the squadron’s commander, said in the wing’s account of that training.
