The Defense Department has provided Congress with a $12.9 billion list of unawarded construction projects, some of which could be delayed so the appropriated funds can be used for barrier construction along the U.S.-Mexico border.

The list includes $1.7 billion for Army projects, but it remains unclear which ones, if any, might be tapped by the Trump administration. The fact sheet provided by DoD with the complete list of unawarded projects notes that no funds would be diverted if Congress approves the 2020 Department of Homeland Security budget proposed by the administration. It also states that funds for barracks, dormitories and family housing are exempt, and that no project scheduled to be awarded before Oct. 1 will be touched.

Under this guidance, many projects remain targeted. For example, $1.1 million in reception and training barracks projects at Fort Jackson, S.C., would be exempt from cuts, but a $53 million hanger in South Korea for unmanned aerial vehicles, a $41 million munitions disassembly complex at Picatinny Arsenal, N.J., and $160 million for an engineering center and parking structure at the U.S. Military Academy in New York could be affected.

A big project that would escape delay is $99 million for a cyber network center at Fort Gordon, Ga., that is supposed to be awarded in May.
