Not all 'Failures' are 'Disasters'... 2

[JohnRBaker]

I know these are not exactly the class of 'failures' that we've come to expect in this forum, in particular because here the outcomes were exactly as predicted, except in a couple of cases that didn't go quite as planned :-0 Anyway, enjoy (I assume the structural guys will get a special kick out of this):

The ones they do in dense urban areas always make me cringe... if anything goes wrong, it'll go wrong in a BIG way.

That is a whole half hour of fabulous entertainment. Woohoo!

One of the side videos is pretty good; I just can't figure out why there are so many dashcams in Russia(?).

Because almost no one in Russia has auto insurance so this is one way to have the evidence necessary when someone else causes an accident and you need them to pay-up.

Thanks John for that tidbit of info, many, many, times I've puzzled over why it seems everyone in Russia has a car cam. That makes total sense.

Not just lack of insurance... there are a lot of organized bump-and-sue scams out there.

Great half hour.

I was hoping that the water tower ones would have some kind of surprise ending. Like the tank being full. Maybe even full of fireworks.

[JohnRBaker]

As for the water-tower shots, yes I was expecting to see a splash as well. That being said, the one phenomenon that I DID notice was that when a tall chimney was part of the structure being demolished, that often a large puff of 'smoke' would be seen coming from it right after the explosive devices were set off due to, I assume, a rush of air being forced up the stack as a result of the blast's shock-wave.

Fascinating, thanks for sharing. Almost seems like they were choreographed in slow motion. Noticeably missing was the Hudsons building in Detroit that stretched for blocks that was demo'd in the late 90's, but I did see a few other Detroit icons meet their demise. Interesting how those buildings took months or years to build but only seconds to destroy. One other thought....we have a ubiquitous number of "building" codes, but interestingly enough I am not aware of any "demo" codes. Seems like there would be a code solely dedicated to the demolition of buildings given that the risks are the same or higher than those associated with new construction.

 

[IRstuff]

Demo seemingly tends to be an art; many of the experts can figure out how to place and time the explosives without doing any sort of rigorous or mathematical analysis. I don't know if that's the case now.

MotorCity, no code per se, but there's a building body of knowledge of best practices.

Our company (demolition engineers) expects that someone will try to codify it in the next 10-20 years.

At 1:20, I'm pretty sure those Philip Services guys were just "hamming it up" with liquid gasoline on the upper stories. The building didn't actually start to go down for 10 seconds, until the charges on the lower level were set off.

At 8:28, I was in the audience watching that one (from a much safer distance!)

[JohnRBaker]

I suspect that some of the 'explosions' that we've seen in movies may have been legitimate demolitions with some added pyrotechnics to enhance the effect.

Thanks, that was a good video; I especially enjoyed seeing the old Elmhurst-Maspeth (Queens NY ) gas tanks coming down.

I can imagine these guys going home at night and, before sitting down to eat, they set the stage by lighting the candels and pulling the tablecloth out from under the dinner.
