The award was made on September 17, 2021, under unrestricted procurement with no set-aside.

Place of performance is Ellsworth AFB in the Belle Fourche-Cheyenne Valleys region of South Dakota.

The originating pre-solicitation notice, posted in October 2020, indicated an estimated project cost of $70–100 million with a 36-month construction schedule beginning in the fourth quarter of fiscal year 2021. The evaluation criteria emphasized contractor experience with airfield paving, corrosion control hangars, aircraft hangars, and facility construction on active military installations, as well as bonding capacity within the project magnitude.
