The company who built the Cowboys Facility.

No, not an engineer but back in the 50s I was in the army and our platoon leader didn't route step us across a 12' long by 6' wide wooden bridge made of 2x6s across a storm drainage ditch and in only a few seconds that bridge was vibrating so violently we couldn't stay on it and it flipped us into the ditch and almost came in on top of us. The fall was only a few feet so no one got hurt but I became a believer in harmonic resonance right then and there.

I suppose that could have played a role but I suspect just the downdraft/updraft/shearing forces would have done the job.

Yeah, it's hard to say at this point; I'm just guessing and grabbing at straws. I'll be very interested to see what the OSHA investigation determines to be the probable cause.

According to Wiki, it was August 1985....unless there was more than one at DFW.

The one you're referring to is the one.. I remember too.

It would be good to state your qualifications for making such statements. I assume you are a licensed mechanical or civil engineer with access to the drawings and calc packages for this structure, as well as the appropriate building codes?

... I have put three of these structures up in my lifetime. The first was a storage facility for Habitat for Humanity and they used it for storage on a multi-residential neighbourhood project.

In each case I did have a chance to view the engineering drawings because we had to put in the piles.

The next time we explored these "CoverAll" shelters was when our football organization was talking about pairing with our town to build a multi-use facility that would house a hockey rink in the winter and a covered field for both soccer and football in the spring/summer and fall.

At that time we were looking at the Titan series of buildings offered by CoverAll (the American division is called Summit).

I'm not trying to put the company down, but knowing that originally these structures were considered for storage I would hesitate to look at them for sports purposes. Especially the Titan series. Our committee felt in the end that this was not the way we wanted to go for many of the reasons I have stated before.

Thanks for the insight.

I haven't perused the rest of the forum yet, but I saw on ESPN that 3 Summit Structures buildings have collapsed since 2003. Not a good track record. FWIW.

Not sure if anyone has seen or been in a storm w/a microburst. The town I live in was hit w/some of these and I've never seen damage like that. Trees far more rooted in the ground completly uprooted and houses actually looked like they had been blown up. Just a very nasty storm. No more no less.

im thinking that the microburst had alot to do with it, but at same time they are saying on espn and nfl network that the company that built the bubble, has had 3 other buildings that collapsed since 2003, yes, thats 3 not one other like we have heard, but 3 other buildings;
