I drew up a quick design option for a pre-cast concrete wall, not dissimilar to many proprietary systems currently on the market.
To be classified as a “wall” rather than a “fence,” the barrier must also be a continuous, non-porous construction.
This distinction might seem purely semantic, but Trump has made himself very clear on the matter, saying, “A wall is better than fencing, and it’s much more powerful. It’s taller.” So we’ll take him at his word: He wants to build a .
One of the biggest choices that a builder has to make is what material to use for his or her project.
For Trump’s wall, I would first dismiss concrete masonry unit (commonly called cinderblock) construction because each block would have to be put in place and set in mortar by hand.
The finished product would probably be acceptable, but construction would be outrageously labor intensive and therefore costly. While it is cheap and readily available, it can be easily penetrated by a pair of wire cutters, an angle grinder, an oxy-acetylene torch, or just a Chevy going really fast.
Even though extant barrier sections along the border make use of wire mesh, the United States Border Patrol is constantly battling to repair breaches and, as stated above, this kind of barrier really falls into the category of “fence.” That leaves concrete.A concrete wall would meet all of the basic project requirements, and as a bonus would also embody the gray-faced antipathy of America’s immigration policy.There are two major types of concrete construction: The hot, dry climate in the border regions would complicate cast-in-place construction because high heat tends to screw up the chemical reactions that cause concrete to harden.There are very few occasions in American political discourse that require the input of a structural engineer, but when Donald Trump took a question from Univision’s Jorge Ramos regarding his proposed United States-Mexico border wall at a press conference on August 25, I heard the clarion call: RAMOS: How are you going to build a 1,900-mile wall? The challenge of Trump’s border wall is not technical, but logistical. What’s more complicated is building a building that’s 95 stories tall. On the other hand, human beings have built a 2,000-mile-long frontier wall exactly one time. And it was accomplished only through a centuries-long building campaign that necessitated the forced labor of millions of Chinese peasants. I build buildings that are — can I tell you what’s more complicated? There are at least 30 buildings that have reached a height of 95 stories or more, according to the obsessively detailed database at Skyscraper Page.com, and there are even more in the design phase or under construction.
