Walls are NOT brought to the site. They're too big and heavy for that. They're poured at the site and then tilted up into place. Hence the term "concrete tilt-up".
True, but it doesn't matter, they still are a shell and will collapse under any large pressure difference. The way to fix this has been known for a long time, pop out panels to relieve the pressure.
I live in Southern California but have been following this story because of my interest in weather, logistics, and construction. This is a first-rate piece of journalism. Well done! Clearly, the weather event was extreme. Yet, downbursts aren't unusual for Phoenix - or other metro areas where warehouses use tilt-up construction. What were the specific structural failures - and specifically why did they occur? Design is one thing; construction quality is another that must be considered/investigated. Construction materials too.
A microburst is a powerful downward blast of wind. It knocks planes out of the sky. I doubt the building codes allow for such an event in your average thunderstorm. There will probably be more in the future though. Building codes will have to be updated.
Back when I was a local truck driver I used to deliver loads to warehouses at 47th Ave & Polk St (one block north of Van Buren) and another around 55th Ave & Buckeye and in both buildings the roofs leaked. This was around 1982 to 1984, just a short time after they were built. Definitely quality issues even way back then. I think the former Revlon warehouse at 43rd & Van Buren had the same problem.
IMO there will be an immediate need to rewrite all construction codes perteining to warehouses and supermarket type buildings. It is urgent that walls materials etc. be more serious than what is seen in this amazing podcast. I fully understand the prudence of the engineer in charge of finding the causes.
The fact that they used big glue lamb as the main beam running the full length of the building supported by what looks like only 6-8 inch round poles says a lot. A building of that size should have been supported by big steel I-beams or the same type of beam that they had the roof sitting on. and those beams sitting on concrete pillars or concrete filled steal pols that were at least 2x as big as the ones used in those buildings.
Your structural engineer is a joke Just look at the damage Concrete and the lack of rebar and if you’re really curious, grab you a chunk of concrete and go get it tested I’m sure you’ll find it much weaker than specified
When have you seen a huge concrete slab being transferred from one place to another? These are poured on the ground and then let to cure. Then they lift them up and have them tilting to then attach them. Whenever you have time take a drive down to where they are building these things and you’ll see how they’re made.
Probably has a lot to do with the weather. Phoenix weather gets extremely hot during the summer, winters are cold and the buildings expand and contract. Cracks form, water starts to leak in causing more damage. Thermal drones could pinpoint potential problems that could cause a collapse like this.
Lived in Phoenix from 1955 to 2003 - looks like those buildings were made of cardboard! I remember the storms and water in February 1980 when my sin was born! And then the storms and water in 1973 roads were covered with water too Hugh to even drive through! This is nothing new!!!
😆😂 Neither. There were several powerful microbursts that hit this area causing the partial collapse of several buildings. Whether they could have been built more structurally sound is impossible to say. Sometimes nature just produces a storm that the average company could never afford to reinforce against. By the way Doppler uses radar which is close to the weakest of EMR. It is used for documenting weather events. It has no destructive capacity.

There is no mystery here, these long and tall walls have tremendous pressure put on them by differences in air pressure and they simply collapse. Just look at the picture. They literally fly apart. Even if you supported the walls, the roof would still fly off. Anyone with a brain can calculate the forces involved.
Need to increase your building standards . Where this won't happen again. Yes, those storms are rare. But this should have been planned for in the building . But I bet it was not planned in the design to survive this.
A storm like this is probably rare. So consequently building standards are not set up to handle really extreme storms. And businesses will build according to the lowest standard they can get past those standards. It's all about the bottom line anyway.
I think the constant hot cold expansion of the metal weak in the building really hot day times Cold desert like nights, the desert needs to be abandoned as it always has been over this centuries you just don't live there it's too hot.
If the same company built these warehouses it 100% warrants more investigation into the quality of these structures
Somebody has no idea what they are talking about...
@@Look_What_You_Did I don’t know what I’m talking about because why?
Are you guys saying a THIRD building collapsed!? Without a plane even hitting it!!??
@@Swampfox42 okay that one was funny 😂

Build quality in the US just seems shocking
The engineer seems to know NOTHING.
He doesn't make money by saying it is a simple thing to explain.
I live in AZ. This building just doesn’t look like there is much to this structure. There are MANY of these built in the Valley
You are correct, and they have and will continue to collapse.
True

My roof leaked for 15 years at 19th and Van Buren until I had it foamed.

Prudence isn't the right word, he knows as well as I do what is going on here. It has happened many times before.
Very reminiscent of the October 2010 storm. That was crazy.
they're called 'tilt ups' because they just attach the warehouse walls together like they're building a doll house ..

Building Code Standards?
took you a month to ask owners about their losses, and make a news story about it. talk about burying the lead.....
It's as if the weather is changing. Every year... a little bit different. Little more severe. Are you in the pot of water about to be boiled?
If you start that pot at a low temp, I might not notice.
