On August 31, 2017, the Trump administration announced its selection of four construction companies to build concrete prototypes of the President’s “big, beautiful” wall along the southern border.

As the Washington Post points out, Congress set aside some $20 million to build the prototypes, and each of the four contracts awarded is worth $400,000 to $500,000.

Construction of the concrete prototypes — which will measure 30 feet wide and up to 30 feet tall — will take place in San Diego in two weeks, and are expected to be completed within 30 days of breaking ground.

Below is information — including contact information — on the four construction companies chosen to build the concrete prototypes:

Following the construction of these concrete prototypes this fall, a new set of contracts will be awarded to construction companies to build the border wall itself.

Those contracts may or may not be awarded to the companies that built the prototypes. Estimates for the border wall’s cost range from $21.6 billion to $70 billion, excluding maintenance.

And while a wall was a central promise of Donald Trump’s presidential campaign — and one which he’s willing to shut the government down over — in a private call to Mexican President Peña Nieto, Trump downplayed its importance, calling it the “least important thing we were talking about” from an “economic issue.”
