The hard hat was an invention by a rock scaler at the site. He turned 2 baseball caps back to front and dipped them in tar several times till they hardened.
The graphics are retro and minimalistic, while at the same time being extremely informative, clearly presenting each particular idea or concept. It's brilliant!
Thank you. All the folks that created and produced this video of Hoover Dam should feel good that they provided a public good for all. A wonderful presentation.
Yes--thank you for recognizing them. Their hard work and brains gave us a much higher standard of life than they had. My dad was born in '24, so too young to have worked on the dam, but its engineering always awed him. And of course, to men his age, it was always Boulder Dam.
I have been there many times and it is something to see in person you can't really appreciate it until you have been there amazing feat of engineering.
“A place called ‘Boulder’ on the wide Colorado… I slipped and fell into the wet concrete below…They buried me in that great tomb that knows no sound… But I am still around…”
My dad worked on the dam. In order to be hired he lied an said he was a welder. He ended up being an office worker. Used to have a photo of him standing in a huge concrete pipe probably 20 feet in diameter. Maybe part of the diversion tunnels. Also a photo of him at the bottom of the spillway. Very scary to see the enormity of it all. And to think that was done in the early 30s with what now would be primitive equipment and slide rules instead of computers. How did those engineers figure all that stuff out? Mind blowing!
The engineers used the technology available at the time because the Government said build it! Ever wonder what it would look like if built today? If it wasn't built would there have been a Las Vegas Or Los Angeles today?
The basic principles of physics were well known long before the dam was built. Doing all the calculations with slide rules wasn't difficult, it was just a lot of hard work to do and check all the sums. The people who did the calculations that way in those days were known as "computers". Much more advanced things were designed using slide rules, like Concorde for example!

I'm proud and happy to say; I was the co-supervisor of the very first fireworks show done at the Hoover Dam ('93'-ish). We set up and fired from the helicopter pad (a fet yards south of the power plant). This was for a party thrown on top of the powerpoint building where it touches the actual dam. Cranes were used to lower/raise the tables, chairs, etc for the party. We also got a tour of the plant with the massive turbines...the day after our show two of us took a long-trip down the river-at one point climbing up to about thirty feet and jumping it. One of the most memorable moment from my (crazy) life.
We take so much for granted 😢 This short educational post really helps in our understanding of how complicated the project and the tremendous complicated construction equipment that needed to be manufactured to undergo the the completed project that STILL stands today. Later, I loved to hear at the dam’s visitors center that they retrofitted the old generators to the latest advanced generators that greatly increased the power output of electrical wattage. What an accomplishment, Hats off to all of you that built that useful structure and the people that lost their lives for it. THANK YOU!❤
Fantastic tribute, really, the the brains and brawn of hardworking guys. This video is fascinating in itself, but also recognizes the hard work and serious application of intelligence that gave us a much higher standard of life than our grandparents had. My dad was born in '24, so too young to have worked on the dam, but its engineering always awed him. And of course, to men his age, it was always "Boulder" Dam.
Pretty sure this is the best recommendation by Yt presented to me this year. Love everything about this video and can't wait to see what videos from here are next! 🎉❤
Watching from UK. Hope i get to Visit this one day as it blows my mind on the Size and work that was given to this dam all those years ago . A true World wonder at the top for me.
Shaft brake, I imagine, applying just a small amount of pressure to slow it slightly down until it is in phase and then lock it in to the grid and release the brake. Also water gate adjustment works
300 feet of digging through millions of years of muck and rocks never seen by man ever would be kinda cool IMO. Amazing piece of engineering, I visited the dam twice and took the tour down inside, worth it.
Very interesting, and to understand how water generates electricity, great engineering, technology and hard work of all the workers involved in this project construction From Washington DC
My grandfather worked on Boulder (Hoover) Dam and later on, worked on Glen Canyon Dam. I remember visiting him while he was working on Glen Canyon, his eyes were always bloodshot from the sandstone dust created from his jackhammer. Lived into his 90's.
Also about the construction of the diversion tunnels, in pictures they had to put steel grates at the entrance where the water would flow through and out of the other side to prevent large rocks getting sucked into the tunnel and clogging it up
When I watch the 1930's documentary on the building of Hoover Dam I was really impressed by the construction of the extensive infrastructure before the work even started on the dam itself.
great video. Another bit of clever engineering.... the pins that connect the steel penstock cylinders to each other were frozen, then quickly installed. Their thermal expansion locked them into place.
Our visit to the dam was awe inspiring. Its sheer size is amazing, and the guided tour inside the dam is one we will never forget. An engineering masterpiece that is unmatched. However, with the dwindling water level in Lake Mead, the dam's usefulness for generating electricity has been seriously hampered. Hopefully, weather conditions will reverse this downward spiral of Lake Mead's capacity to store water. Excellent video.
Using same old software probably...I'm no animator. I just watch Corridor Crew. Perhaps Lesics should just use Unreal Engine 5, so Lesics can see the animations and renders in real-time.
@@EyesOfByes that's not how animation works, it's like drawing: using better paper and pencils won't change your ability to draw, they look bad simply because they stopped putting in as much time(or money).
@@nerds-nonsenseprobably time. I can make these animations pretty realistically, but first of all it would take me 15 hours to model everything, then an hour to setup whatever the specific animation would be, and then rendering times would be insane if you don’t want noise. On my gtx 1070 and 32gb ram I predict each frame would take me 30 minutes to render, maybe even more with the water simulation. If I would use the less realistic settings, it would be able to render in real time. If you have 24 frames per second which is really the limit before the eye can tell it’s choppy, each second would cost me 12 hours to render. That’s 720 hours for 1 minute and this video is 17 mins and 30 seconds. Realism is not worth that in my opinion for a video like this. It doesn’t make it any more engaging. Especially compared to the cost.
I love the hoover Dam and its industrial aspects. This video has some interesting facts that most other videos don't. Despite it using animation, it's a great video.
its crazy how much effort goes into building a single pier. Lovely explanation and summary of the whole process. Ive always wondered how this is done when looking at a bridge
@@insideoutsideupsidedown2218 well maybe it was a different temperature area in that specific area because we were in a dude ranch and the temperature was like 90°F

“ Tunnel boring machines unpopular at the time”?? They simply did not exist for hard rock tunnels. First introduced in the 1950’s. Also the jumbos did not drill sideways as the illustration shows.
5:48 The Story of The Hoover Dam is by far the most comprehensive documentary on the actual construction of the dam. Herbert Hoover, himself an engineer was in a perfect position to work with the Bureau of Reclamation and oversee everything from the bidding to the building. The structure is known as a gravity arch dam which uses the simple physical properties of weight and the distributive properties of an arch. The entire structure is a huge plug in the canyon walls sitting on a huge foundation.
Question for engineers, would those drainage holes 9:17 at the bottom (the ones that take up the groundwater) help prevent the Saint Francis Dam collapse?
My great grandfather worked on the dam. My grandpa told me stories about it. He said when someone fell into the concrete they would sound a whistle alarm and everyone would take a moment of silence then they would all continue working. The dam contains the skeletons of the fallen.
@@edgarplett5863 you think they poured it a foot at a time? What a joke. 😀 I've laid foundations for buildings that were poured 10ft plus at a time. You should look into how they did the construction if you don't believe it. The majority of it was built with pre made blocks yes but there was also the lower foundation of it that had to be blasted/dug then set with concrete. There were guys on rope a pulley set ups moving material and setting blast charges after they drilled into the mountain. A lot died from cave ins that buried them so the bodies are most definitely still there. You do realize they had to excavate mass amounts of the mountain before the construction even began right? Also in what world do you think a company responsible for all of that would publicly admit fault for the deaths of people? Some men fell a hundred or more feet into the ravines. There was no way to recover them that didn't risk more lives. Some men were saved if possible but most weren't even attempted. My grandpa and my great grandfather were both veterans of real wars. They wouldn't lie, they had nothing to gain from it. My grandpa was born the same year his father worked on it. I have photos from them that are probably considered confidential. My granpa had some of the highest level of national security clearance imaginable. Some of which aren't even in text books. I think I'll believe him over you and Google. 👍
@@edgarplett5863 odd how youtube keeps removing my reply. Almost like they don't want the truth out. 🤔 The majority of the main dam was pre fabricated blocks yes. But before those were brought in they had to blast the mountain sides on either side very deep. Many guys were lowered in with ropes/cables to drill and set charges. They poured a lot of concrete in the mountain sides and under the dam to establish a base. Under all of the blocks is a lot of deep pours. I doubt his father would lie about losing friends there. He was a vet as was my grandpa. They saw stuff he didn't tell anyone and stuff he told many people, but he was no liar. He had photos of a lot of it. His family wasn't poor so they had cameras even when most didn't care about film. He was always big into photography and engineering because his father was. My grandpa was a civil engineer and line runner in the first war he served. I have his old albums somewhere. There's some brutal photos I saw after he passed that he never showed me but he said were in there if I look. You don't have to believe me. I'm just sharing what I had heard and seen photos of. If I find the albums in my stuff I'll try to upload some for you.
@@vinceruland9236 you don't have to believe me. I don't seek approval from strangers, I just enjoy sharing history. My great grandfather was one of the engineers that helped in the design of the dam. He personally knew many of the workers as well as met FDR at the ceremony they held there. My grandpa was born April 9th 1934 and was a baby while his father helped finish the dam. They were fortunate to be somewhat wealthy during the great depression due to his father. Do you know what it was called before Hoover dam?
I come from a family of engineers. (I chose a sales career). Engineers are a different breed. Great problem solvers, gifted with great knowledge,autism spectrum, arrogant .

Good animation
the video is solid, but the random loud music outbursts are terrible, distracting and a pretty big turn off.
A bit of trivia: 96 men died in the construction of this damn. The last man to die was the son of the first man to die. Great video, thanks!
Good pun in the first sentence
It was more than that, it's been Said that the company wanted the number to be less than 100 for the public eye. The real number was more like 110-120

This is the video that should be shown at the Hover Dam before the power plant tour. The one they show now was made in 1980 and is horrible.
And 88 years later the dam is still working to perfection and hopefully will continue to serve America for years to come. Great video.
except it's not. there hasn't been a lot of water or power production for quite some time.
That is true. Power output has decreased significantly, and the cost to maintain is being questioned.
It would be working for the next 262 years when it would become a strategic location for the New California Republic

His family wasn't poor so they had cameras even when most didn't care about film. He was always big into photography and engineering because his father was. My grandpa was a civil engineer and line runner in the first war he served. I have his old albums somewhere. There's some brutal photos I saw after he passed that he never showed me but he said were in there if I look. You don't have to believe me. I'm just sharing what I had heard and seen photos of. If I find the albums in my stuff I'll try to upload some for you.
@@vinceruland9236 you don't have to believe me. I don't seek approval from strangers, I just enjoy sharing history. My great grandfather was one of the engineers that helped in the design of the dam. He personally knew many of the workers as well as met FDR at the ceremony they held there. My grandpa was born April 9th 1934 and was a baby while his father helped finish the dam. They were fortunate to be somewhat wealthy during the great depression due to his father. Do you know what it was called before Hoover dam?

Amazing. Another amazing feat of engineering is the Golden Gate Bridge.
Close to 100 men died building this dam. They took the ultimate risk for a wage, but society is better for it.

They built this almost 100 years ago and it's still standing. Modern engineering projects/government built roads can't last that long🤔
hello sir I am your new subscriber from Pakistan sir please can you tell me that which software you use for this video
Great video very informative and great content brilliant narrating also.
I come from a family of engineers. (I chose a sales career). Engineers are a different breed. Great problem solvers, gifted with great knowledge,autism spectrum, arrogant .
@9:10 I really liked your videos.. but please use clean containers to show your experiment.
A very informative video. Thank you very much.
Never thought Superman will lift mjolnir 😂😅
Increíble construcción y logro de ingeniería 😯
