Despite a recent lawsuit from California politicians, construction of the President Trump’s border wall has entered an exciting new phase of construction.

Legal Insurrection readers will recall that the Department of Homeland Security had an open-call for plans, and hundreds of construction firms submitted blueprints for consideration — despite threats of boycotts from disgruntled immigration activists. Eight plans made the grade and prototypes are being assembled along San Diego’s Otay Mesa Border.

The building process will last about 30 days, Customs and Border Protection said.

The agency may pick several winners, or none. It said in a news release that the prototypes ‘will inform future design standards which will likely continue to evolve to meet the U.S. Border Patrol’s requirements.’

…The details of the design remain unclear. Each prototype will be up to 30 feet high and 30 feet long.

Bidding documents say four of the prototypes are to be solid concrete and four are to be made of ‘other materials.’

Trump said Friday that the wall should be see-through, appearing to cast doubt on the concrete designs.

The construction site is close to the existing high-security fence which marks the border through San Diego and to the east.

Mindful of the “Burning Man – Dakota Access Pipeline” protest drama that took place in North Dakota, local authorities are taking special precautions to protect the construction site.

The San Diego County Board of Supervisors voted Tuesday to ban items that could be used as weapons, such as baseball bats, knives, and rocks, in certain areas where border wall prototypes will be built.

An area has been designated in Otay Mesa, near the U.S. Mexico border where large crowds may gather in a “free speech zone.”

…County officials said they want to restrict protestors from using any weapons that could be used to disrupt the peace.

The board’s unanimous vote gives law enforcement the authority to issue misdemeanor citations to those who bring items that could be perceived as weapons to areas authorities deem to face credible threat for violent demonstrations.

And while no protests have been reported (yet) there has been an accident that injured one of the workers.

A man plunged 40ft down a hole at a Mexico border wall construction site.

…He survived without suffering serious injuries and was back at work shortly after.

US Customs and Border Protection (CBP) spokesperson Carlos Diaz described the incident as a ‘misstep’.

Here is some diversity we might all appreciate: The contractors who were selected to proceed with prototype development.

Caddell Construction Co. of Montgomery, Alabama, and W.G. Yates & Sons Construction Co. of Philadelphia, Mississippi, were awarded contracts to build one wall of concrete and one of other materials.

Other contracts for concrete prototypes went to Fisher Sand & Gravel Co. of Tempe, Arizona, and Texas Sterling Construction Co. of Houston. Contracts for prototypes of other materials were awarded to KWR Construction Inc. of Sierra Vista, Arizona, and ELTA North America Inc. of Annapolis Junction, Maryland.

It will be interesting to see what the final products will look like in 30 day!
