Failure of a planned failure - Pontiac Silverdome

Failure of a planned failure - Pontiac Silverdome

RE: Failure of a planned failure - Pontiac Silverdome

That's not too uncommon, look for "Failed Demolition" or similar terms on YouTube.
I'm glad I'm not the one that gets assigned to go check out those charges and see why they didn't go off!

RE: Failure of a planned failure - Pontiac Silverdome

Was going to post this, thank you for doing it fitst.

Going to be hard and unsafe to go back into the building (under the failed dome!) to investigate, remove the unexploded-but-still-dangerous explosives now present, add more in those holes and joints, rig them for blasting, and then get back down.

If you don't remove them, then you have to find them and remove them from under the demolished rubble AFTER the second blasts go off.

RE: Failure of a planned failure - Pontiac Silverdome

The old dome isn't there- there's no 'under the dome' to contend with.

It also appears that the explosives detonated as planned, they just didn't cause the structure to lose enough stability to bring it down.

RE: Failure of a planned failure - Pontiac Silverdome

"Rick Cuppetilli, the executive vice president at Adamo, told the newspaper that 10 percent of the explosive charges in eight key locations failed to detonate due to wiring issues that crews are investigating..."

RE: Failure of a planned failure - Pontiac Silverdome

I stand corrected. My previous post was based on watching the video.

RE: Failure of a planned failure - Pontiac Silverdome

Interesting to go back in without a 'really big hardhat'. I recall going into a building in pending collapse and had the Building Official stay outside to call 9-1-1 if necessary.

RE: Failure of a planned failure - Pontiac Silverdome

I guess you could describe this as a sort of "crowd-sourcing" approach to bringing down the Pontiac Silverdome:

Explosives didn't work, maybe rocks will take down the Silverdome?

RE: Failure of a planned failure - Pontiac Silverdome

As many times as the Lions imploded in there, maybe it just can't be 'ploded no mo'.

Quote (Miller Force 10 from Navarone)

Yes. Well, they're probably experts at building things, whereas I'm an expert at blowing them up, and you can take it from me that one would need a good eight hours to make a decent job on that bridge.

RE: Failure of a planned failure - Pontiac Silverdome

Yea, so he blew a dam instead and the bridge became collateral damage...

RE: Failure of a planned failure - Pontiac Silverdome

In the original design, the "steel columns" don't appear to be used to support the concrete structure but only as a component of the roof. At some point the roof structure was modified to include a ~cantilever mechanical perimeter roof~, which looks quite robust. If they had had any success, they might only have brought down the added roof section.

RE: Failure of a planned failure - Pontiac Silverdome

Looks like they were able to successfully complete the demolition today. Whew.

RE: Failure of a planned failure - Pontiac Silverdome

This happened to be in my "backyard". On the radio this morning, the CEO of the demolition company that said he was not in the business of entertaining onlookers with a successful demolition, his job was to simply demo the building. He explained that the main explosives designed to sever the columns went off, but the kicker charges did not due to a wiring failure. Apparently they double checked the wiring and it was intact (which I am not sure how you verify after detonation) but suggested that it could be defective wiring. He also said that they could have demo'd the building by mechanical means, but they came to an agreement with the city to implode it as a way of drawing attention to the potential for redeveloping the site.

Between the Lions and the building demo, seems like nothing ever went right at that place.

RE: Failure of a planned failure - Pontiac Silverdome

If the goal was to draw attention to it, their plan worked. If it went off without a hitch, we wouldn't be talking about it.
I would call this a success.

RE: Failure of a planned failure - Pontiac Silverdome

I thought those systems did a low-voltage check of the entire wire-out to ensure this sort of thing didn't happen...

MacGyver,
They may have been using outdated equipment.

RE: Failure of a planned failure - Pontiac Silverdome

I don't know if all the links will play, but most seem to be YT ones, but this has clearly prompted this article.

For those that like that sort of thing.....

Also: If you get a response it's polite to respond to it.

RE: Failure of a planned failure - Pontiac Silverdome

Thanks for posting that LittleInch. Some of those were very impressive.

RE: Failure of a planned failure - Pontiac Silverdome

Are those fields of VW diesels surrounding the stadium?

RE: Failure of a planned failure - Pontiac Silverdome

"I thought those systems did a low-voltage check of the entire wire-out to ensure this sort of thing didn't happen..."

Actually no, nowadays they don't use electrical detonators. At least not for big jobs like this. They use detonating cord.

RE: Failure of a planned failure - Pontiac Silverdome

But isn't det cord set off electrically, I mean they don't light a match and run, right?

RE: Failure of a planned failure - Pontiac Silverdome

STALguy is correct here. You can see the smoke from the detonating cord in the video.

No. The parking lot is in use as overflow production storage for a nearby plant.

RE: Failure of a planned failure - Pontiac Silverdome

Interestingly, at least 60 of the VW diesels stored AT THE SILVERDOME were stolen and given new titles and sold at auctions, according to news reports, so I guess that confirms my theory.

RE: Failure of a planned failure - Pontiac Silverdome

This article from Sept 29, 2017 says there are almost 9,000 VW diesels parked at the Pontiac Silverdome.

The almost 9,000 Volkswagen diesel vehicles parked at the Pontiac Silverdome could remain there for some time.
VW is still trying to determine its strategy for dealing with the cars bought back from customers as part of the resolution to its massive diesel cheating scandal, in part because the company does not want to adversely affect the market for its used cars.
