Savage

It's a joke? 96 workers "sacrified their lives" so Mr Savage was not much thinking about work safety. 96 mate.

John savage is the master savage in pioneering Dam 🦫 constructions

Did you see it during construction?

There are videos from the time period showing it's construction. It will soon be dry though.

Because he was savage 🫡

That was a giant project just imagine the injuries, bursitis and plain old aches and pain the workers had from this. I drove through in Oct 1983 and I wish I would have stopped for a tour.

He created a monster, putting cities where they have no business being. Now, with climate change, its a monumental disaster with no viable solution. Mr, Savages vision was short sighted, like most engineers. Take the automobile, please, just take them all.

He didn`t pay much attention to the health and safety of the workers.

Why are there almost always 7 entries on lists like that?

@@wholeNwon 7 signifies completion or perfection. I've also heard it described as a spiritual number.

@@Pumpherstonsmith Hard hats were invented then in order to protect workers' heads from falling rocks. The workers themselves invented them because they really needed them. Now every blue-collar worker is required to wear a hard hat, which is really dumb.

Very interesting video! Had the privilege of finally seeing it when we were in Las Vegas a few years ago and took a bus tour to the Grand Canyon ! We stopped here to see it from the highway. It is so impressive !!

As a teacher of civil engineers I can say that your comment is inaccurate.

The cars are on the wrong side of the road...

"civil engineer" Professional masturbation isn't engineering.

Gotta love YT creators.

@@BlueInOrangeAgain While I normally let it slide. Cush Yadav made a statement that cannot stand and stated his credentials to back up his statement. It is you tube etiquette to copy the OP's form in the reply thus Travis correctly stated his credentials. One might therefore ask you: Why attack a teacher? You ask: what is inaccurate? Certainly the expression "beautifully explained" is subjective. I feel it was dumbed down for STEM and diversity candidates. The pace was WAY too slow and ultimately it contained only a brief overview, NOT the promised clickbait secrets. 1:00 His first drawing of compression and tension was "inaccurate". While the engineering lesson was somewhat correct his exaggerated drawing clearly showed BOTH sides in elongation. He claimed that cool water in the pipes 6:23 quote: "set the concrete quickly and easily". NO it slows the set not quickens it. He further makes it sound like the water was stopped as soon as the set took place but (of course) the concrete was cooled for months to slow curing. He also forgot to mention THE SECRET that they used ice in the mix to reduce heat in the concrete further slowing the set. His pictures show blocks he calls 50X50. The illustration suggests they were 50X50X50, but the lifts on this job were 2 ~ 4 inches at a time. In hindsight it is believed that the block staggering ultimately had little to no affect on even cooling because of the ambient temperatures and direct sun. Fun fact: There are parts deep inside of the hoover dam that are still not completely cured 86 years later. The myth that dead workers were entombed without anyone knowing is false. The concrete was poured 2 ~ 4 inched at a time.

We forgot their names... soooo we'll just call them legends.

He said he is going to pay tribute to 63 who died. I wonder what thw fellow has planned in their memory?

Such an accurate statement

Do you have any specific examples? I don't know anything about construction... But it seems unlikely they would just "wing it" as they were building it, without having a very detailed plan.

@@shard_dnb well a small example would be the excavation of the rock, it’s easy for an engineer to say “yeah jut cut this shape out in the side of the mountain”. But there are guys who have spent their entire lives working explosive mining, learning from generations of guys who have perfected it over their lifetime. Those guys are experts in their field and know exactly how to get it to break and fall where they want it safely and efficiently, something the engineer would have no idea how to accomplish. Or the water pipes in the concrete, there are guys who have spent their entire lives working with concrete and know exactly how to get the concrete to cure without stress cracks and such, easy for an engineer to draw some pipes on a plan and say we’re gonna cool it with water as if cures, something totally different to get in their and design a system to do it effectively. Something again a engineer just doesn’t have the experience to do on his own.

@@davidreynolds731 They didn't spend "lifetime" working explosive mining and they didn't "learn from generations"... Dynamite was invented only 64 years before the construction began in 1931. The experts working with dynamite are not "blue collar workers"... They are engineers who calculate where to put the explosives and how much of it to use. I get what you are trying to do - appreciate the "little guy" - the blue collar worker. It's true they did all the hard work, some even died there. But the claims you are making? You are reaching. Your next point mentions the cooling pipes... But those are in the blueprints. You can actually google the original blueprints. The engineers designed it, the workers just followed the lead. I am pretty sure Savage wasn't the only one, there were most likely many more engineers (experts) working for him. Those are the people who solved all the "variables and issues" as you called it. If you want to keep pushing these opinions, we are going to have to agree to disagree. I am out of here, not going to respond again, these are just youtube comments anyway, there is nothing to be gained from this debate... Have a nice day, bye! 🙂

@@shard_dnb pretty typical of people on the internet, it’s easy to disagree in a comment section then run away.

hehe :D

Very true, sadly.

Its only 25% full and since 1983 has been dropping overall each decade.Man can build but he cant make rain.

@@glennpowell3444 The issue is that we've been slowly getting rid of the rain by heating the planet and causing draughts by messing with the water cycle. That and maybe if Arizona and California didn't keep draining the Colorado River dry to grow water intensive crops in the fucking desert the draught wouldn't be nearly as severe.

Actually he can; cloud seeding. I find it highy coincidental that Lake Mead was nearing levels that would halt power production and possibly drinking water to surrounding areas just as the north experiences a snow pack 221% higher than normal.

It’s feats like these that piqued my curiosity to become a civil engineer. I never finished but I always wondered what could’ve been had I did. I love these mega projects and I can’t get enough the modern mega structures of our time

@SARCAPITAL you would most definitely been working with some insufferable individuals who would expect you to be like "one of them" in order to be accepted amongst their ranks. That's how it worked in the coal industry. As a foreman / engineer, you're expected to hunt and fish and own a collection of "Rredneck toys", such as 4 wheelers and boats and a 70,000 dollar pickup truck for hauling air around... They expect you to like country music (BARRRFFF), suck ass to certain bosses, be related to a multitude of individuals within the company, place work over God and family; for, it is THEY who are your God and your family. The non-believers replacement is but a phone call away, and thanks to the chicken shit "at will" clause governing management employees, they can terminate you for such a reason. And they expect you to spy on other workers who are drawing workers compensation, especially the union workers. And you better not be afraid to let some safety go out the window. Shutting the belt line down because you spot 3 rollers that have seized up and are starting to burn the conveyor belt isn't a good enough reason to shut down for 20 minutes to replace them. Shut downs for necessary maintenance cuts into the shifts foreman's production bonus he receives every quarter. But get caught letting such violations go... that shift foreman WILL NOT go to bat for you, neither. They'll just make you out to be a liar and a trouble make before the federal inspectors of MSHA if an investigation takes place. Saying you're "new" doesn't help either Now, that's a most extreme case. But I guarantee you other engineering and labor-related companies out there operate the same way. So be at ease to known that you at least got to avoid some of that I mentioned

I would drain one side of the Hoover dam and show Arthur 2 On the Rocks on it, like the world's greatest drive in theatre

Savage was extremely competent, but wasn't brilliant. The ideas that made the dam possible should be credited to A. J. Wiley, who taught Savage the techiques.

Dam

Actually it's 86, and it's getting older every day.

I’ve been to Vegas 5 times and been to the Hoover dam once. It is a must see

I’ll be going over this summer, are you able to go inside the dam and get tours around it??

@@Nikkk6969 Yes, the tour I always take is the one you go inside. You get to go all deep in the bowels and it takes you by the massive generators you end up at the bottom looking up You should call them or maybe they have a website, and ask them what all the tour entails, and how much it cost make sure they're actually still doing it.

Great!

Dale Great information on Wiley. Seems odd this video is 2 months old yet Hoover dam is basically offline. Lake mead is so low those towers aren’t even in water now. Totally ineffective they say. Also if you look at video of dam near end you’ll see the water level is low they used Goggle image.

@@LaGrandeBayou Lake Mead looks almost dried up. 100,000 people are getting their power from another source apparently.

Yeah it’s wild. Lake Mead in the late 80s was full to the top of those intake towers. It’s dropping so fast now you can almost see it happen.

True. The lead person usually gets all the credit. Kind of like Thomas Edison.

What’s crazy is Savage learned the process of cooling concrete and arching the structure from a guy named W.C Wiley on an earlier dam project. This is the work of WC Wiley not J Savage.

Your friends don't know what's good

you did a great job! ☺

mechanical and electrical engineering play roles too for turbines & generator controls 😄

Yes ofcourse. But as a civil engineer, I was looking at the Civil aspects. Every Engineering field work hand in hand for the betterment of the society.

Notice how the environmental impact is not even mentioned on this list

@@phole1100 We should have gotten Edward Abbey's thoughts on that!

Good to see a friend here I hope you find a nuclear winter 😀

Without the coolant pipes, it would've been forever and a Day to dry and cure. With the addition of the coolant pipes it was estimated that The concrete used in the building of the dam wouldn't be finished with the drying and curing for around 50 yrs After the entire project was completed, and it was finished ahead of the schedule.

@@bruceperkins7253 Concrete doesn't set by drying. Just curing.

vroom: You are correct: Concrete is "set" in hours and "cured" to a working strength in days, but gets harder and harder in normal projects for 40 years. Due to being hundreds of feet inside the dam away from air and now kept moist and cool it will take 100 years for parts of the dam to cure.

@@bruceperkins7253 No, the coolant pipes SLOWED DOWN the set and cure a little (different things) cooling did NOT speed it up. The Nevada heat is bad for pouring concrete. Dries too fast and cracks. The best temperature is 60°F. They slowed the set and cure so the temperature was evened out to prevent cracks.

@@Engineer9736 Yes, you are right. It does not dry like glue with the evaporation of the solvent, but NO the curing heat is from a reaction actually called "hydration" and does require the removal of the water (drying). It's like a catalytic, reaction but drying is as good a word as any for concrete.

I saw in a documentary that the workers on the dam fashioned hard hats out of tar. They were grossly underpaid.

I have visited this amazing dam in 2019 my friend almost got killed by a falling rocks. This rocks were so big that we joked he should have played lottery that day. So I fully agree with the fact that hard hats must have saved many lives.

Old style hard hats are terrible, we need computer hats with WI-FI, cell phone charger & lights.
