In a step toward meeting one of President Trump’s most prominent campaign pledges, the Dept. of Homeland Security is seeking firms to provide prototypes of a U.S.-Mexico border barrier.

In a presolicitation notice posted on Feb. 24 on the website (, DHS’s Customs and Border Protection agency announced that, by about March 6, it plans to issue a solicitation for design and construction of “several prototype wall structures in the vicinity of the United States border with Mexico.”

In the notice, Customs and Border Protection said it plans to conduct a two-phase procurement. In the first phase, each firm must submit by March 10 its prototype’s “concept paper.” Then, by March 20, the list of proposals will be narrowed down, the agency said.

For firms that make it to the second phase of the procurement, Customs and Border Protection plans to issue a request by March 24 for full proposals, “which will include price,” the notice said. It adds, “Multiple awards are contemplated by mid-April for this effort.” The notice doesn’t specify the wall’s length or estimate its cost.
