Trump chooses companies that can build a wall in Mexico

The United States Department of Homeland Security announced on Thursday that four companies were selected to build prototypes of the controversial wall proposed by President Donald Trump along the Mexican border.    

The companies come from four different states: Alabama, Arizona, Mississippi and Texas. The companies Caddell Construction, Fisher Industries, Texas Sterling Construction and WG & Sons Construction were in charge of producing a concrete wall, which will be nine meters long and up to nine meters high.    

According to the Customs and Border Protection Service (CBP), the four models will be built and one team will be responsible for conducting resistance tests over the next two months.   

The four contracts are valued between $ 400,000 and $ 500,000 each. In all, more than 200 companies even submitted design designs for the wall. Next week will also announce more contracts for the construction of prototypes made of other materials, other than concrete.    

The total cost of building the wall between the two countries is estimated at tens of billions of dollars. The Mexican government has rejected the idea of ​​paying for the project, which has generated a diplomatic crisis between countries.    

The construction of the wall was one of Trump's main proposals during his presidential election campaign.
