The government's proposal reflects many of his campaign promises, including that the wall be tall and "beautiful".
The U.S. government has put out a call for proposals to build a wall along the border with Mexico that President Donald Trump ordered as one of his first official acts after the inauguration.
The bidding documents released Friday provide important clues as to what the Trump administration hopes to erect on the 1,200 miles of border with no physical barriers. The specifics are technical within reason, reflecting Trump's mission to restrict border crossings.
Immigration activists are expected to protest construction of the wall, deploying tactics learned during the long, bitter protests over construction of the Dakota Access Pipeline near the Standing Rock Sioux Reservation in North Dakota. They should be "physically imposing in height" - 30 feet is preferred, though 18 feet is acceptable. The largest would stretch more than 10 miles and would wall off the entire area between the Hidalgo and Donna bridges.
Time-consuming legal challenges are sure to accompany Trump's orders detailing stricter enforcement at the border and in the interior of the country, said Leon Fresco, who led the Justice Department's Office of Immigration Litigation during the Obama administration. It also must stand up to attacks from sledgehammers, pick axes, torches, and other tools for at least 30 minutes (though four hours would be better), according to CNN. Congressional Republicans said the wall would cost between $12 billion and $15 billion and Trump suggested $12 billion.
However, Americans living close to the Trump border wall should be able to see something a little nicer than a colossal monstrosity from their bedroom windows, according to officials.
Donald Trump's Mexican border wall will be nine metres high, hard to cut through and look good - at least from the U.S. side - according to documents posted online.
There has been feverish speculation about the Mexican firm's possible involvement in the project since Trump's ordered construction of the wall to begin immediately as one of his first acts as president.
Mexican President Enrique Pena Nieto canceled a White House visit over the wall issue in January. The plan foreshadows a greater emphasis on prosecuting people who cross the border illegally, those who come back after being deported, and anyone tied to human and drug smuggling.
