U.S. Customs and Border Protection (CBP) has initiated the process of testing prototypes for the border wall along the southwest U.S. border, The Hill informs.
Eight of the sample walls were completed in San Diego in October, according to the ABC News after six companies were selected to build the prototypes.
The eight prototypes need to be 18 to 30 feet and four of them are built of concrete, while another four are made of various other materials. Physical tests of the prototype wall started on Monday, however, the official testing period began on November 27, according to ABC. Physical testing of the samples consists of efforts to breach the walls, using tools such as jackhammers and saws.
The sample walls mark CPB’s first efforts to construct the wall, which was one of President Donald Trump’s cornerstone campaign promises. The Trump administration apparently have made the wall’s construction a priority.
The Department of Homeland Security expedited the sample walls’ construction in August through issuing a waiver for the process.
