The federal government has awarded a contract to build and operate a sprawling tent camp at Fort Bliss, an Army base in Texas, to serve as an immigrant detention center.

In the Trump administration’s latest move to vastly expand space for such detention, the work would turn the base in El Paso, with more than 1 million acres and an airport, into a deportation hub with 5,000 beds, according to a US Department of Defense contract notice. That would make it the largest immigration detention facility in the country.

The contract for Fort Bliss is worth $1.26 billion and was awarded to Virginia-based Acquisition Logistics Company through a special program that directs federal dollars to small businesses, according to two people familiar with the matter who asked to not be named discussing something that hasn’t been shared publicly. The Army is putting up $232 million for the work, the Defense Department notice says. The Wall Street Journal reported earlier that the contract had been awarded but did not include its value or the winning bidder. Ken Wagner, president and chief executive officer of Acquisition Logistics, declined to comment.

The Fort Bliss contract is by far the biggest ever for Acquisition Logistics, which Wagner, a retired Naval flight officer, founded in 2008. It specializes in supply chain management and other technical services, particularly for the US military, according to Wagner’s LinkedIn profile. Acquisition Logistics has received contracts worth roughly $29 million from the Defense Department over the past five fiscal years, mainly for logistics support work, according to government records. Most of that was through set-asides for small businesses.

The company doesn’t appear to have any experience with detention, but earlier this year the US Army paid Acquisition Logistics more than $5 million for “lodging and conference room services” related to the agency’s work at the Southern Border under the Trump administration.
