Via Rosie Perper at Business Insider:
The border wall collapsed about midday Wednesday and landed on a row of trees, according to the police in Mexicali, a town on the Mexico-California border...
The fallen length of wall was about 130 feet long.
Agent Carlos Pitones of the Customs and Border Protection sector in El Centro, California, told CNN that the wall was newly installed and had been set in concrete that had not yet hardened.
According to CNN, the National Weather Service recorded wind gusts up to 37 mph when the wall fell down...
Simple rules of construction, especially for high-walled structures like warehouses I've been seeing along the Polk County line where dozens have been going up: REINFORCE THE MOFOS.
And even then, has anyone working on these 50-foot monstrosities put into consideration how resonance and wind vibrations would work against something sticking up THAT high across a wide and flat landscape?!
We've had about 80-90 years of construction history telling us we need to model out tall structures for wind effects because this is what you get when you don't:
Which always begs the question: JUST WHAT THE FCK ARE WE TAXPAYERS PAYING FOR IN trump's GODDAMN CONSTRUCTION BOONDOGGLES.
