The U.S. Customs and Border Protection Agency has announced that construction on eight border wall prototypes has begun. The prototypes are being built in San Diego and must be completed in 30 days.
Half of the prototypes will be made of concrete, while the other half will be made of “alternative materials” and allow agents to see through it.
Requirements stated that the wall must stand up to “sledgehammer, car jack, pick axe, chisel, battery operated impact tools, battery operated cutting tools, oxy/acetylene torch or other similar hand-held tools.”
According to ConstructionDive, the prototypes are expected to cost between $2.4 and $4 million to construct.
