Watching this, it springs to mind the story of the Citicorp Center in NYC. The decision during construction, to save money and time by deviating from the design using welded steel plates to bolted plates instead, combined with a lack of calculations for the loads quartering winds would apply to the sky scraper, set the building up to collapse during a storm with the potential for great loss of life. Luckily, the flaws were discovered in 1978 after inquires from a Princeton University engineering student, Diane Hartley, who was writing her senior thesis on the building and its unique architecture, and the building was repaired before a disaster occured. Hartley wasn't told until about her role in saving the building.... it wasn't until 1995 when the New Yorker magazine revealed the story of the flaws and secret repairs that she realized her work resulted in emergency repairs which saved the building.

One small correction. There WAS a warning, moments before the collapse, I understand that someone who worked in mines said he heard cracking and creaking that his training told him meant an imminent collapse in a mine, so he bolted for the door, making it out just moments before the disaster.

I have so much respect for an architect who shows up to a collapsed building he designed to help find victims. His design wasn't really the main cause but he couldn't know that at the time and others have hid from such events. I respect the fact that he didn't hide but it sounds like he didn't spare himself any blame, god rest the souls of every one touched by this. There were to many cooks in the kitchen so to speak and I get no impression of intended wrong doing by anyone really. It bring to mind only a few other disasters of engineering that made me think no harm was really meant or fully understood when built.

[@CaffeineGeek]

Disasters such as the Knickerbocker Theatre collapse should serve as a cautionary tale to those in industries beyond construction. In my field, there is always pressure to cut costs, meet budget, and deemphasize the importance of items not visible to the customer. Years ago I was brought on a project that played out in a similar way. Costs were cut in critical areas, unapproved hacks implemented, lack of ownership on assigned tasks, anything not visible was deprioritized, and a general "not my problem" attitude was pervasive. When my concerns were brushed aside, I resigned. Six months after the project was complete, disaster struck and the fallout nearly put the company out of business. While no one was injured or lost their lives, it was extremely disruptive for customers and financially costly to remediate. Everything could have easily been prevented has the issues addressed in this video been taken to heart.

[@ericwilner1403]

Other industries, oh yes. There's an old saying: if builders built buildings the way programmers write programs, the first woodpecker that came along would destroy civilization. The Knickerbocker Theater seems to have been built very much like a program, with many ill-considered, last-minute, ad-hoc changes. At least it wasn't having hasty design changes applied every few days after it was finished, though. ("After that last patch, the fire curtain won't lower and the toilets in the gents' room are backed up? We'll have another patch in a week or two.")

P.S: could you please do a video on the Pemberton Mill of 1860? Most people regard it as the worst structural design failure and it’s cause was down to many similar issues as with the Knickerboker Theatre.

[@18booma]

@@badwolf7367 The sway of money is often stronger than the sway of the engineer. But the engineer must at least try to be part of the solution, not part of the problem. Also, this is another reason why unionizing is so important. The individual has no say, but if the workers are united, especially in such a sought after field, they are able to affect change and prevent the preventable.

[@TrineDaely]

Plainly Difficult covers a lot of these kind of failures, too. You should see the ones on mall collapses. Pretty sure there's a civil or structural engineering channel that covers failures, too, as well as Fascinating Horror. No single channel has every disaster, and of the ones covered by multiple channels you'll get additional pieces of information from each of them. There's good channels that are even more specific in focus, like dam failures, roller coaster failures, boat design, etc. You never know what piece of knowledge could make a difference, from wall strength to easily accessible fire exits or hazards you may not generally think about that are more linked to human behavior.

[@saab9251]

Sadly many cases of unionized labor have had similar failures due to the “not my job” syndrome that has fallen over a lot of industrial construction. Structure guy didn’t locate the anchors because that was the concrete guys job, but concrete guy said it was the anchor guys job, anchor guy said it was the steel workers job, and the steel workers build the structure without anchors because “if they wanted anchors they should have installed them already.”

[@18booma]

@@saab9251 I don't know hey, sounds to me like anchors might be the anchor guy's job. But I would love to hear, how you think unionization is to blame for people not knowing who's doing what. Isn't the whole point of management to manage the allocation of work?

[@sixstringedthing]

05:35 "However, these revisions would quickly received sign-off anyway ... with no calculations reportedly being made to ensure load capacity of the new materials or designs by any parties involved". Kinda weird to be having "flashbacks" to Kansas City when the walkway collapse happened _nearly 60 years after_ this incident, but the above phrasing just sounds too familiar. Sometimes we learn from our mistakes after just a single tragic death. Other times, it seems the lesson must be horifically reinforced before it actually sticks. And then greed goes and undoes it all. Thanks for another grim but fascinating video Sam, excellent research and presentation as always.

[@fararelliott]

That's a grand explanation! There is one memorial to the Knickerbocker victims. It is a memorial chapel at St. Margaret's Episcopal Church on Connecticut Avenue, which lost 15 parishioners in the collapse.

[@filanfyretracker]

a good rule of thumb in the Northeastern US, Never trim budget in anything that revolves around keeping the roof up. You will eventually meet a winter that has your number. I mean structural elements should never get trimmed budgets but you certainly are a lot less likely to suddenly get an extra few hundred tons on a roof in say Atlanta.

[@marqbarq5977]

The Tivoli Theater in neighboring Columbia Heights in wash DC (14th and Park NW) was built after this with a structural modification that the entire roof was supported by external walls to ensure that this couldn’t happen again. This disaster changed the way theaters were designed.

Thank you for being a teacher. Got to be such a difficult job. I didn’t know until probably my late 30’s that different media leaned any type of way. I think Covid made more folks aware. Think it’s an awful thing, still I don’t understand why it exists. Why politics & media are intertwined that way. Does it normally follow the owners or journalist’s views or what? Maybe it’s whoever pays them more in donations. It’s really creepy, like 1982 movie type stuff. Tell them never to watch that by the way. Never the same again, wished someone had warned me. But, yeah, would really help if I could tell which news was a just the facts mam type of reporting

[@TrineDaely]

@@mustangnawt1 There's also a media bias site that will also give you an accuracy rate of sources. As in many industries, follow the money. Who owns the company is the obvious question, but also who are their audience. Big media owners (like Koch family but not just them), they've been buying up local TV and radio stations, websites, local and regional newspapers, etc. Sometimes you have to follow a chain of owning companies higher and higher since they'll own many companies, and those companies will own multiple companies (rife problem in many industries). At the end of the day, in most cases it's about people with lots of people making more money with no regard for people hurt in the process.

I inspected an acoustic wall between two cinema screens a couple of years back as the suspended ceiling had partially collapsed: turns out that this massive partition wall has a movement tolerance of 80mm at the top (which was about 20m in height) and it wasn’t anchored to any roof sections by design, and when it moved it pulled all of the supporting trim that held the suspended ceiling perimeter in place away from the cross tees by 80mm and so they dropped to the floor. 80mm … and the manufacturer said that was acceptable tolerances.

As soon as you started in about the war and the changes that were made regarding construction due to the hefty requirements of materials for the war effort, I groaned inwardly. A long time friend worked for a big cemetery in Seattle and he told me that during the wars the concrete grave liners (that the caskets are set into) were made without usual steel rebar reinforcements. Every so often the weight of the soil (+ rain making it heavier) on top of the graves will overcome the strength of the concrete liner lid and the ground will sink when the concrete gives way. He doesn't like dis-interments, but they have to replace the old liners/lids.

I think it's worth noting that given that this was a family theatre many of those lives lost were family members, including children. And many would have suffered for a very long time given the storm and the time it took to dig through that debris. How awful for the survivors to have to grieve this. The whole incident reminds me of the Champlain Condo collapse in Florida, which I believe this channel covered. Although not caused by a storm, many of the contributing factors are the same, 100 years later. It seems we do learn the hard way, and sometimes not well enough. I thought it was a nice touch for you to list the names of the victims here. Especially given that there isn't a memorial for them at the site. Thank you.

@@dfuher968 One of the things you'll see time and time again in all kinds of structural failure problems is that it take accidents with serious loss of life before appropriate checks and balances are put into place. The one thing that allways tends to annoy me about too many of these stories however is that no standards or checks and balances will be in place that would have prevented, yet various parties will try and often succeed in holding them accountable for not following said non-defined nor previously enforced standards. Reality is for both reasons of human psychology and practical factors, (like who someones going to pay to hire), anyone who goes beyond the laid out and enforced standards In the US this is made worse by it's tendency to have a billion different agencies for everything, each with their own piece of the country to cover.

@@darthkarl99 Ehm, I disagree. You don't see KZbin videos about the non-collapse of a building. But that doesn't mean all buildings collapse all the time. The lessons learned from a disaster go to improvements in the building code. As a result, the reasons why structures fail become more and more intricate. E.g. nobody would build a wall like this which is too weak from the start anymore. And everybody would at least require calculations for the novel design choices.

[@darthkarl99]

@@eljanrimsa5843 You missed my point i think. I was lamenting that it takes a disaster for those lessons to be learned in the first place. Ideally good regulatory practise should be to look at things and see what in each design submitted case and see what the weakest links are and take note, then every once in a while review all sets of notes to see if there's a common weakpoint across many designs of a similar nature and step in then and do somthing regulatory. Instead potentiol weaknesses only get noticed when somthing fails and good hard searching to see if it's a common issue generally only starts after it leads to a disaster.

Buildings will just fall down, bricks made with mostly sand crumble under a light touch. Cardboard used instead of proper walls, hidden under a thin layer of plaster. People do die, as we saw in Florida. No doubt since then it’s happened all over the world, a simple cause, greed & lack of morals. I watched 1 earlier & a man lightly punched his fist into a ‘wall’.

[@jueabaddon2168]

Just found you recently and have been on a binge. Nice work.

The financial issues and "expedited" construction schedule during WWI are the tell here. Everything else about the cheap or inexpensive construction flow from that. It was a rushed schedule with an inadequate budget for the building.

[@kokosan09]

the picture after the collapse is truly horrifying.

[@elen5871]

dude I audibly went "Jesus" the way you portrayed that, can't even imagine how that would have been

[@oldschoolman1444]

The continuing theme I see between the failure of structures is trying to get more with less.

[@ShainAndrews]

Basic engineering constraint. Anybody can build anything. An engineer designs it just well enough to function. Tell an engineer to design with 200% safety margins and you will get it.

I swear, ur videos r so well done. Everything about them r superb. I hope this channel explodes with growth.

Complementing individuals whom obviously invest a lot of time an effort only to rewarded with the bare minimal effort of partial words.

[@rainydaylady6596]

I'm sure there's a good reason for it, but why do so many buildings have flat roofs? When I lived in Phoenix AZ so many houses had them and yet they seemed to have more trouble with the rain. Yes, it does rain in Phoenix. Lol. Mostly during monsoon season which causes even more damage. Not only that, but they build homes and roads in what are dried up washes and then they have trouble when a monsoon hits and there's flooding. Now, with climate change I wonder what kind of issues we'll have in Portland, OR since we're not used to large amounts of snow.

[@FranNyan]

Likely some combination of a flat roof being able to house HVAC equipment, allowing for easy additions, roof access, or it just being easy/cheap. I live in snow country, where it seems even more of a bad idea, and yet, there's one I can see from my window.

[@ZGryphon]

They're easier to build and require less material, both of which make them cheaper. Some architects also favor them for aesthetic reasons (a big building like a theater with a gabled roof tends to look like a barn, which is usually not the effect the designer is going for).

[@sixstringedthing]

In Australia we have the reverse problem. Very very few areas of the country will ever see even a light snowfall, but due to our largely Anglo-based cultural/architectural heritage we still build houses with pitched roofs for aesthetic/traditionalistic reasons, where flat roofs could do a perfectly fine job with less materials/labour and far fewer complexities re. drainage and waterproofing, while also allowing far more of the upper storey's full volume to be useable living space. But people still like the look of a pitched tile/corrugated steel roof I guess. :)

[@craigjensen6853]

@@ZGryphon Unless you're talking about the Olympia Arena in Detroit! It was affectionately known as "the barn", among other things.

[@ZGryphon]

@@craigjensen6853 Well, I did say "usually". :) (Weirdly, the Cow Palace in San Francisco doesn't have a barn roof, although it isn't flat either. More of a giant Quonset hut.)

[@feltongailey8987]

Interesting that there were no outward signs of that wall "working" its way out plumb. At least, not to the extent that someone would notice it, evidently.

[@evilchaosboy]

Too many different "corner cutting" acts here. "Good enough" was the mantra at the time and it was just as wrong then as it is today. Opulence and finery are beautiful until you find yourself crushed by them. This architectural terror was compromised and they all knew it. It burns me that to this day humans will still "cut corners" given the opportunity. Great show!!! \m/

[@jfkastner]

Great work, thank you!

[@johnboulton1109]

Another superb and fascinating case, thanks for producing such a well researched and interesting video. Looking forward to your next.

[@boowiebear]

$2 Million is nothing for this building in today’s dollars. So many corners were cut!

[@JustAllinOneResource]

NOT once did he speak about the people who not only lost their lives in this tragedy but the families who no longer have their loved ones with them ever again. This guy had no remorse whatsoever but only felt bad for himself. This guy was a Sociopath.

[@thetayz72]

"At a cost of $77,000, $2m today .." No, please, stop. It hurts

[@keouine]

How odd that I have a fuzzy memory of learning about this from a plaque while living in Adams Morgan/ Dupont circle back in 1992. it must be a false memory then if there's no memorial. I must have seen the photos in a book Lost Washington.

[@lynngehringer1073]

SUBSCRIBED! Love your voice and content! Always interesting and I learn something new with every Video! Thank you! I really appreciate the time you invest to create these stories for us!

[@abstracts2004]

Great video. I have seen a plaque in reference at this location in the “Adams Morgan” neighborhood as it is now called.

[@joevermeulen8324]

Great vid. Thanks for making it. Are we going to see part two of the Korean Ferry disaster soon?

[@BrickImmortar]

Working hard toward a hopeful Feb release. A lot to cover & a very emotional story to tell...

[@thepinkyprincesspoetc.a.5767]

Brand New to your Channel Hon... Love ❤️ it! Looks like Lots of Interesting Videos to explore...Love learning about Disasters I’ve never known of till finding them on your channel! 🙏 Thanks for your hard Work and the Research it takes to put each one together...Here we Goooooooo...💚💜🤎❤️💙🧡💚

[@eganjoe]

Interesting documentary, as are all yours I've viewed. Please consider me a supporter of your work. I'm a retired reliability engineer, former CRE, 6SBB, blah, blah, blah. Godspeed to you.

[@Watts378]

Another well done video 👍

[@QueenRenne]

Oh I know this is gonna be interesting to watch! 💯🔥

[@Maleko48]

so incredibly sad to think of how guilty those "responsible" felt that they felt it necessary to take their own lives

[@taebundy658]

You peeps are tops!!!!! I could binge on your vids any day.

[@riotintheair]

It took a while to watch this... I live 3 blocks from this spot and even knowing about this event broadly and that it was a century ago I just couldn't quite watch it yet.

[@danjf1]

It was many years ago but at that intersection area or open area, an inexpensive plaque could have been set up long ago...
