Skywalks Crumble in Missouri! - Massive Engineering Mistakes - Engineering Documentary

[@ElizabethMayo-sf4wg]

Im grateful for this series. Thank you.

I was observing a remodel of the skyboxes at a university stadium. At one point the contractor was to cut out a three inch diameter round steel rod that went floor to ceiling. Curious, I reviewed the original drawings and discovered that the box level was hung from structure above. That work was stopped and a new design was quickly created.

[@RobinOConnor-ex7tk]

I remember watching the national news coverage of the sky walk collapse. They broke into the regular tv programming when it happened. I remember that one of the reasons for the collapse was the people dancing on the sky walks. It's one thing to build something that can hold up to people walking across it. It's far different to build something that can hold up to the rhythmic stresses from marching or dancing. This is apparently so well known that the military always breaks cadence when crossing bridges.

I went to the Hyatt that night. The ares was interrupted with a call for anyone experience with heavy lifting to come help[. Belger cartage located 3 blocks away was on of the first to respond with gravy lift cranes.

[@michaelwilber774]

This is insane, ive grown up in kansas city my whole life and never knew this about my city. My family never talked about it. Of course i was born in 1990 so 9 years later.

[@Dovietail]

What was nice about the Tea Dances at the Hyatt was that they drew a great mix of generations and types of people. That is seriously rare!

[@mavfin8720]

I grew up in a small town in north central Missouri. My parents had friends who went to the Hyatt that night, and were among the dead. Yes, I remember it well. I would have been 11 or 12 years old.

[@leonardpearce4512]

I was working in the lobby of the Hyatt during it’s construction, when an architect exclaimed that the walkways had to look like they were floating! The boxed beam at that point were two channels with their backs against the rods with a one inch plate below. He instructed the foreman, Duane, to remove them, turn them around, weld the lips together and no, do not put the plate back on. That architect later committed suicide, most likely because of his guilt of his actions. I talked to the saxophone player, from the second floor walkway, while they were warming up to play that evening. I’ve worked in and around that building for 40+ years. The third and fourth skywalks were replaced with an elevator on the south end of the lobby.

[@Wes-x9p]

@2:56 they show the Kemper Arena, ironically the roof on it also collapsed, gut it was unocuperd at the time. A bolt failure was also the cause of the roof collapsing. The collapse was caused by a design change due to an incompetent Arcatectural requirement..

[@zorrorides1]

Hyatt Hotel disaster: LOTS of failure information left out. Both Architects and engineers responsible as well as miscellaneous iron and other installation contractors all had a serious hand in creating this failure. Plus management allowed an unlimited number of dancing adults that far exceeded the design criteria on the walkways at the time. I was involved with the engineering company that assisted in analyzing this failure however these comments are only my humble personal opinion. I noticed that the city fathers are so concerned with honoring the fatalities that they are unable to even mow or pull the weeds out around their memorial. That is shameful.

[@pazsion]

not only was something welded when it was sopposed to be solid... its also not steel, but iron... and not even forged or hardened.

[@marilynkirby-roach187]

At least the UK building was demolished prior to opening it and it collapsing on hundreds of people. If this had been a corporate/public building hey probably would have built it anyway and just dealt with the repercussions

[@michaeldowson6988]

Decades ago I did topographical mapping for proposed civil infrastructure projects. GPS pretty much killed off that career, not long after I got out of the business.

[@AlfredNewman-o7z]

I retired from San Antonio Storm Water Operations, back in 2004. We all knew way back then that SA Town is full of Karst sinkholes, and acidic soils... Why the surprise?

[@SadisticSenpai61]

We all had a big laugh about how they got the measurements wrong and had to jackhammer the tops off the column. I will say that the now completed overpass is very nice. Although ppl do tend to get rather grumpy at me when I go the actual speed limit on it. That was an extremely dangerous intersection. Even before I moved to Ames, I'd nearly been in accidents several times there just trying to avoid merging traffic while heading north to visit family - especially when there was a game at ISU or a concert in town. Edit: The speed on the cloverleaf wasn't the problem. That's the case for all cloverleaf interchanges. No, it was the fact that traffic going from HWY 30 East to I-35 North had just the length of the short bridge over HWY 30 to merge into traffic. And at the same time, anyone traveling on I-35 North that wanted to take the HWY 30 West exit, needed to merge into that same small space to take their exit at the end of the bridge. The I-35 South entrances and exits were perfectly fine, which is why they remain unchanged. To help understand _why_ this was such a huge issue, Iowa State University is west of this intersection along HWY 30. So yeah, game days or when there's a concert in town? Or even just on weekends when the university is having some kind of event or students are moving in/out? Yeah, that intersection is a major bottleneck.

My Grandmother survived the Kansas City, Missouri Hyatt Regency sky walk crash.

[@pimlican]

Havens Steel Company of Kansas City changed the design.

[@danielfox9461]

She's a lucky woman, several people who survived the collapse almost drowned when broken water pipes started filling up the floor and trapped people couldn't get above the water

[@lordcaptainvonthrust3rd]

As time passes we will lose the survivors of disasters. And we should never forget the people related to those people who survived these disasters for keeping the memories in our minds. Thank you for sharing

[@pazsion]

😓 @pimlican any documents available? that wasnt steel... and those beams never should have been split thats not how they are made.

[@sandramayes8679]

Very sad, lots of older couples died that day..

[@basspig]

I'm surprised the building in the UK only cost 60 million pounds. 25 years ago they built a high school in my town for $120 million and I remember our property taxes quadrupled to cover the cost.

[@SunnyMacDuffeeMota-tw9vl]

I remember walking on this walkway it really seemed to bounce as you walked on it So , I wasn’t surprised when I heard about it collapsing

[@annetteolson2428]

Me too. A couple of weeks before the collapse I started to walk across the top sky walk, and thought better of it because of the bounce.

[@cathyvickers9063]

Re: the Sheffield building: thank God it wasn't inhabited! Unlike a certain condo in Florida...

7 min in and 3 ads already, this will be fun.

[@saggitarusspirit401]

If you pay for youtube you will have no ads, its worth it. Like 10 bucks a month. Been a subscriber for 3 yrs now. No ads, no commercials

[@godblessamerica7048]

I've driven through Ames, Iowa, on I35 many times.

[@JJ-Streaming]

Is it scary? I hate bridges

[@godblessamerica7048]

I never noticed to tell the truth

[@ClairePetersen-p6d]

Whatever happened to the story about steel girders falling apart,made with defective steel?????????

[@Frogginnator]

I used to live on the "old" highway 30 in Ohio. The part that used to go through cities.

[@amyjojinkerson-b6o]

those beams should have been back to back

[@jamestyrer907]

They sould have had shear blockage inside them where the rods went through and an adequate (square) shear washer under the nuts. Also, they could have used a splicing nut (of sufficient length to support the load) to have continuous rods.

[@Frogginnator]

Basically the City of San Antonio messed up

[@amyjojinkerson-b6o]

always check the site

[@Cindy-i9r]

The earth is opening up all over the world not just America

[@raymondsullivan7230]

Looks like that whole building came down due to poor Construction RPS 111

[@johnhaddad3401]

i was entertained.

[@amyjojinkerson-b6o]

100 years good luck

[@haydonditchburn2194]

Interesting. I can only wonder at the comments if any of these had occurred in China..!!

[@susanfarley1332]

Tofu dregs!

[@gorl9642]

Did Chinese build it with ToFu?????

[@ryzlot]

DEI meets engineering JR

[@mikezero1282]

nothing like compiling together old news that someone else covered.. and pretending its new

[@glyn1]

2 hours ago click bait

[@beezknees4339]

Mistakes? More like planned

[@kevinquist]

27:26. "professors" description of Pilings? Absolute worst description of what a building piling function I've ever heard. bar none. been teaching for 30 years and that is an absolute -0- points for that answer. At least the narrator had better concept.

[@monstrositylabs]

San Antonio sucks

[@ricardofierro7041]

Okay

[@SX939]

SO FRICKEN LATE TO REPORT, CLICK BATE CHANNEL

[@hazardtriplezero]

first

[@precisionleadthrowing4628]

let me guess, it was designed by diverse team lead by women ...

[@DedSysOp]

Bros out here making up stuff to be mad at 😂

[@rosscyn1959]

Let me guess...you're gay!

[@susanfarley1332]

It most likely was all men.

[@MelissaWickersham-k4o]

Are you talking about the Hyatt Regency Walkway Collapse? That catastrophe happened in 1981. 43 years ago. Engineering teams weren’t quite as diverse back then as they are now. Just how old are you? Didn’t you know that DEI wasn’t as big a thing back in the 1970s and 1980s as it is now? The men who rubber stamped the design of the walkways and carried them out were cisgender white men.
