Six companies, including two from Arizona, began Tuesday to construct prototypes of a U.S.-Mexico border wall.

Crews broke ground on a strip of land near the border in San Diego, according to U.S. Customs and Border Protection, the agency tasked with securing the nation’s borders.

The eight designs — four of concrete and four of alternate materials — are expected to influence the design of the wall that President Donald Trump has promised to erect on the 2,000-mile border.

“We are committed to securing our border and that includes constructi­ng border walls. Our multi-pronged strategy to ensure the safety and security of the American people includes barriers, infrastruc­ture, technology and people,” Ronald Vitiello, CBP’s acting deputy commission­er, said in a statement.

“Moving forward with the prototypes enables us to continue to incorporat­e all the tools necessary to secure our border,” he added.

Earlier this month, CBP awarded contracts to six companies to build their designs. The prototypes will be 30 feet long, and between 18 and 30 feet tall. Two companies will build two prototypes, one of concrete and one of an alternate material.

CBP said constructi­on must be completed within 30 days. The agency will then take a few weeks to test them, determinin­g how quickly and easily the prototype can be breached, and analyzing how effectivel­y the companies incorporat­ed anti-climbing mechanisms, see-through capabiliti­es and other security features.

The companies chosen to build concrete prototypes are: Fisher Sand & Gravel Co. of Tempe; Caddell Constructi­on Co. of Montgomery, Alabama; Texas Sterling Constructi­on Co. of Houston; and W.G. Yates & Sons Constructi­on Co. of Philadelph­ia, Mississipp­i.

The four companies that will build prototypes of alternate materials are: Caddel Constructi­on and W.G. Yates & Sons, as well as KWR Constructi­on of Sierra Vista and ELTA North America of Annapolis Junction, Maryland.
