Each of the prototypes reportedly cost $500,000 and the six companies hired to produce them have until Oct. 26 to finalize construction.
President Trump is currently seeking $1.6B from Congress for 74 miles of new border wall to be located in southern Texas.
On Tuesday, he shared his excitement for the project, tweeting out, “BORDER WALL prototypes underway!”
Even with the available footage, Roy Villareal maintains that the prototypes may not be what the wall will ultimately look like.
"Part of the intent of the prototypes is to influence the ultimate design of new border fencing," he said. "[The final design] may well not be what you witnessed."
Until then, the Trump administration is currently keeping mum as to how the winners will be decided.
