SAN DIEGO — The last two of eight prototypes for President Donald Trump’s proposed border wall took shape last week at a construction site in San Diego.
Companies have until Oct. 26 to finish the models. Each model costs the government up to $500,000. Bidding guidelines call for the prototypes to stand between 18 and 30 feet high and be able to withstand at least an hour of punishment from a sledgehammer, pickax, torch, chisel or battery-operated tools.
Features also should prevent the use of climbing aids such as grappling hooks, and the segments must be “aesthetically pleasing” when viewed from the U.S. side.
