A section of Donald Trump's border wall between the United States and Mexico has blown over in strong winds.

It came down on the Mexican side of the divide, landing on some trees in Mexicali, in the state of Baja California.

The parts of the wall that gave way had only recently gone up.

They had been set in new concrete, Carlos Pintones, an agent with the Customs and Border Protection (CBP) sector in El Centro, California, told CNN.

The concrete had not yet cured, according to the official.

In my youth, while getting through college, I did a bit of concrete work. It's not really rocket science, as they say. Whenever you have a vertical structure on curing concrete, you attach lots of angle braces, anchoring the structure from the ground, until its cured. And generally, you calculate support based on winds up to 70-80 mph, if it's open country. If there's any doubt, you have a structural engineer do an analysis.

It's pretty simple, in government contracting: you can accept the lowest bid, or you can accept the bid from the company with the most experience and best reputation in the industry. This is very similar to what happened in Puerto Rico with the power grid, where the low bidder was some company in Montana that had zero experience with the technical demands of an aging island power grid, and were generally neophytes.

I think you can see from the news agency photograph that they did have some angle-braces, but only on one side of the structure - the USA side of the border.

Presumably the Mexican authorities said something rather terse and colourful in Spanish when the Americans asked if they could put braces on their side of the wall as well.

The defect with such an arrangement is that when a southerly headed storm blows up and applies windage forces on the northern side of the newly erected structure, then you really do need some counter bracing on the other side if you expect the structure to stay upright long enough for the concrete to cure.

Vive y aprende as they say in that part of the world.

Those don't look as if they were holding anything much - and on the windward side, anyway.

With a thing that heavy, you don't set the whole structure in wet concrete. You anchor in the post brackets, wait for the concrete to set properly, then screw in the posts, attach their angle-braces, then the cross-bars, then the cladding, slats or whatever.
