Yeah, My calculus professor kept telling us like "The golden bridge in San Fransisco is standing strong, thanks to calculus". But how? he never tells us. I only know after I watched some youtube videos.
@@EddieGooch Your professor may have meant because it's actually built from "Calculesium". A rare element made purely of calculus that fell as a meteor to Earth millennia ago. It's how the bridge stands "thanks to calculus". Little known fact! :-P
wonder how long it would take to gather all the information transported in this video, in such easibly digestible fashion, on my own. Prolly days and weeks, without getting to "the bottom" of it all.
I remember reading that Caissons were used to build the platforms that the Brooklyn Bridge stands on, and a HUGE number of workers died or got caissons disease.
@CrabApples Bodaciously Bitter Fruit's what’s this? Is this I who baited the troll simply by calling them out? Please keep replying so we can string this along.
@CrabApples Bodaciously Bitter Fruit's I love how the only two options are "We build shitty things" or "Lots of workers die in the process." There's actually a third option. We have proper safety measures AND we build good quality things, and the people who own the construction company make slightly less profit. Horrifying, right?
Your content is so wholesome and heartwarming. Even your sponsored elements are enjoyable to watch. Your videos are of the rare breed that actually leaves me in a much more positive mindset upon consumption.
no he's right there's definitely something special about this guy's combination of chill & relaxed + seamless easy-to-digest information without any gimmicks. it just really puts one at ease and doesn't betray the feeling with any "hey, now that I have you here" elements, which is hard to pull off with a sponsorship.
Most likely indirectly you did and so the algorithm tries with a related topic. Plus sometimes the algorithm proposes a new subject just to see if you like it or otherwise and if the attempt fails no big deal, NO loss! because you/we keep scrolling down the list and continue watching videos and that's all it matters to the company, simple as that. Cheers 👋 👋
The algorithm might have noticed a pattern of what you want to watch at certain times of day or certain days of the month, that's my theory, although you would have to record what you watch at certain times of the month or certain times of day, etc. over a long period of time to be sure about that :/
It just seems like it. Think about all the videos it recommends that you're not interested in. If you throw enough paste at a wall, one will eventually stick
AmbyJeans I appreciate that greatly. You are the first person to thank me for the work I do , usually the Iron workers , operating engineer's ( crane & all other heavy and light equipment.) That get the attention. Obviously we don't do it for recognition rather a sense of family pride and things like that. We basically do almost every different type of construction while building something below the water , we are licensed and trained to do so , well rounded Dockbuilders are. We do pretty much anything that is below the water level and on the water or shore. One day I'm building a bumper system so boats don't slam into the bridge or the barges , and the next building form work for the freedom towers foundation or even working on the subway tracks and of course there's the divers and tenders who do all the fun underwater work. So its a fun job , lots of different things to chose to do. Thank you again , its nice to talk about what I do every day. Or a summary of it.
Right out of college I worked on Terminal 6 in Portland OR. My job was inspecting each and every sheet pile driven into the Columbia R. to create a row of caissons forming the pier face. As you know pile driving is based on driving to resistance. I marked each sheet pile with an approval chalk mark at the resistance point. When done with this project I figured we had driven the equivalent of 20 linear miles of piling. The caissons were then filled with compacted sand and topped with a 24inch concrete deck. Good memories.

Hey I've worked in coffer dams before... it's a weird feeling knowing you're standing on a river bed and the surface is 30+ feet above your head. And if it fails... well you're not going to have time to think about it.
What, if any, is the "plan" going thru your head in that situation? Something like hug the nearest bouyant thing you can find? I work in a machine shop. In case of earthquake my plan is to hit the E stop and jump inside the machine until shit stops falling from the ceiling and sliding around the floor, then leave the building as per fire.
Been under a lake in a tour. Table Rock Dam. In the cave about 900ft down the guide says u are now under a lake. Hearing water trickle down the walls I was ready to get the hell out of there.
We have to wear life jackets and hope for the best. I've had to repair 2 cofferdam failures in my Career so far, both happened during extreme water levels and no workers were inside during the failure.

It was a joke when they kept sending divers down, but couldn't see anything. I was thinking why not pull dirty water from the bottom of the shaft, filter it and add a bit more clean water so that the clean water in the search area's hydrostatic pressure would push out the dirty water. They act as if people centuries ago would be able to construct something which modern man using modern equipment and techniques wouldn't be able to access. They think there were flood tunnels which are booby traps. No the reason everything floods is because it is a relatively small permable island.

My son is a Union Ironworker. He was given the same option as my other child, 4 years of college I’d pay for. Instead of following my shoes, aviation engineering, he chose the trades. 4 years of apprentice schooling and he’s a fully qualified iron worker and welder. Also got his rigging certification. He’s out there every day in the worst weather, except thunderstorms, working his butt off. I’m so proud that he is truly helping making America great again.
a dutch man came first and made a dam, than they wanted to dry out a piece of land (which was flooded) and invented a way to embody the water before draining it using the coffer dam method
Very cool. I've always wondered how they dealt with the water in these situations, and now I know! One question: Did the Romans and Egyptians etc., use coffer dams as well, or did they have some other method?

In the 1970s my father was a manager in the state park system and they all told their stories. They often had much bigger projects than budgets. Back then they often had to resort to "creative engineering." One of the other parks needed to rebuild a boat launch including the docks and ramps a portion which were under water. The parks often shared equipment so the managers had access to an eclectic assortment beat up machines. Mostly castoffs from other departments. For some unknown reason one of these was an old jet boat. These boats used very powerful automobile engines turning large pumps. The tremendous jet of water shooting out the back of these allowed them accelerate very rapidly. In other words they were delightful things from a time when power was often held in higher regard than efficiency. That park also acquired a backhoe front end loader combination. They used the loader backhoe combo to block the channel leading to the boat launch with dirt .They positioned the boat in the channel with a large plastic tube attached to the output of the jet boat pump and leading to the other side of the dam. The system could drain the area in a rather short time but was very difficult to control. To make matters worse a lot of water was finding its way back in . The boat sucked bottom muck and sand more than once. Still it continued to function until the project was completed. I can't tell you what the level of damage was to the boat. The state sold it at auction shortly thereafter. Perhaps to prevent some other park from trying the same thing.
Always such interesting topics. This is one of those things I've always wondered but never put into words. Now my mind's racing about the possibilities
I do dewatering as my job and this was still pretty cool to watch. Learned alot! We use pumps and coffer dams to bypass water ways, but also install wells around sites to dewater the ground or relieve excess water pressure
Hi, long time lurker on your channel. Japan, Taiwan and Philippines recently experienced earthquakes just this week and I think it's a great time to revisit or expand your earthquake related video. A demonstration or two with different intensities, etc. will be helpful. Thanks for these highly informative videos.
Rio-Antirio bridge had her pillars that the base was built in shore, and then they towed roughly in position, and then they were built as normally. The increasing weight due to construction, submersed the pillars until they where set on their own bed.
You forget one major type of construction, drydock builds. Made out of concrete, steel or other materials its just towed away to a final resting place.
@Rafael If you are curious watch those documentaries: th-cam.com/video/se26Ux9QD44/w-d-xo.html th-cam.com/video/aUqrBV4SiqQ/w-d-xo.html Main difference between premade constructions and those made in keson is that it was probably better to made them in dry dock or just impossible to made keson big enough to build it like this (Troll A). Some tunnels are built in dry dock and then submerged (look for Boston Big Dig). I believe that difference is large at least to mention of that type of construction.
@@piotrlenar5652 it is spelled caisson, not keson which is a nonsensical word, not hard to figure out how to spell when spellcheck (should) offer caisson as the proper spelling. And yes many large formats can now be more eaisly precast at a dry dock and loaded out to location and forgo the need for a caisson and thus forgo the dangers of that confined method of casting.
@@Joshua79C Keson (caisson) sorry, it didn't show it as a mistake so i assumed the word is similar to my native language. And it isn't nonsensical you are just unfamiliar with that kind of spelling. And when I check it caisson is french word and you read it wrong as all words in US english borrowed from european languages.
Oddly enough there is a company with that name and I did not mean it is nonsensical in seriousness, Yeah I figured you do not speak English but Google only shows it as caisson for me and could not find alternate spelling in other language (have not even tried it in translator tool to see how it is written in some other languages), but curious to what your native tongue be.
@@Joshua79C en.wiktionary.org/wiki/caisson Bulgarian and Russian spellings of word caisson are familiar to polish witch my native language is. And I speak english or write in it but not too well :)
I was boating in Seattle on Lake Union, the State recently built a new bridge across Lake Washington, I was curious about how these massive supports were built underwater. Perfect explanation! Thank-you
During my career, coffer dams were quite come. In the early 1900's, my grandfather and great grandfather were divers during the construction of the CPR Bridge in Outlook. Pretty cool standing at the top of the bridge imagining them working so far below.
Really well-presented, great volume, great understandability. I am from the UK so HelloFresh is not an option for me, but it all looks great and American content is fine by me.
Love these, such a great glimpse into very complicated (on tbe actual engineering level) subjects! Like discovery channel was once but its not dragged out! Would have been cool to had seen these in school, so we would appreciate our cities better.
HI, Thanks for entertaining vids. To concider is also what we use in Finland. Buiding in the arctic areas allows us to freece water and create a coffer dam of ice in the winter, then break the ice on the work site. The ice melts away finally on the spring and doesn't use resources at all. Totally natural.
This is actually a question i forgot to search into, I'm glad that not it only reminds me of it, but also learned of how it actually done. Nice videos and thanks for the knowledge.
"Stay warm" he says... ROTFL! After a couple hours that wet suit ain't very warm anymore, and dry suits? Not sure if they are better or worse, just different. We also get 2x-3x-4x pay for working inside of a caisson. It depends on the pressures inside. You get paid for compression/decompression time too.
As a coal miner, I normally scoff at the claims of others and how dangerous their job is. But, I must commend your work. If only I got paid extra for ever hole I had to climb into!
Commercial divers use a loose fitting wetsuit called a hot water suit wich has rubber tubes running inside the torso, arms and legs wich carries water heated in a boiler at the surface. Super confortable for long hours in super cold water

Could you do a video on how drilling deep oil wells is done. How do they replace the bit if it is worn out. And also how horizontal drilling works.
How dare you make me fall in love with engineering.
This is exactly what I needed to watch at 2am
Love this guy's channel. So informative from a technical perspective. How anyone can downvote these videos is puzzling to me.
This channel reinforces my knowledge
I'm no engineer, but this is actually pretty interesting.
The more you know~
This channel is like a free course in engineering. Thanks!!
I'm a commercial diver and primarily work on hydroelectric dams. Even though ive done a lot of what hes talking about these videos are still always fun to watch. By the way though, we don't use SCUBA gear, way different rig that takes multiple ppl to run.
Thanks for collaborating with LEARN ENGINEERING ....due to that i found your channel😃😃😃
What the construction companies should do is form an alliance with Posideon, he can easily move the water for them
Can I just say thank you for sharing the civil engineering world to the everyday person and making it Interesting. You are growing the profession in a positive way:)
In the 1970s my father was a manager in the state park system and they all told their stories. They often had much bigger projects than budgets. Back then they often had to resort to "creative engineering." One of the other parks needed to rebuild a boat launch including the docks and ramps a portion which were under water. The parks often shared equipment so the managers had access to an eclectic assortment beat up machines. Mostly castoffs from other departments. For some unknown reason one of these was an old jet boat. These boats used very powerful automobile engines turning large pumps. The tremendous jet of water shooting out the back of these allowed them accelerate very rapidly. In other words they were delightful things from a time when power was often held in higher regard than efficiency. That park also acquired a backhoe front end loader combination. They used the loader backhoe combo to block the channel leading to the boat launch with dirt .They positioned the boat in the channel with a large plastic tube attached to the output of the jet boat pump and leading to the other side of the dam. The system could drain the area in a rather short time but was very difficult to control. To make matters worse a lot of water was finding its way back in . The boat sucked bottom muck and sand more than once. Still it continued to function until the project was completed. I can't tell you what the level of damage was to the boat. The state sold it at auction shortly thereafter. Perhaps to prevent some other park from trying the same thing.
The irony surrounding the fact that this is an engineering channel - but the camera isn't level - is NOT lost on me.
0:22 "Ham Gradey, and this is Practical Engineering!"
Love from India Sir....
This comment is underrated
How about next video you talk about FOUNDATIONS.
Yeeees, do that one
I like how this guy talks. Smooth and obviously know what hes talking about.
As a bridge historian I am highly interested in this video.
came here from twitter
I have waited so long for someone to explain this! I was always wondering how. Thank you for making this video!
Always such interesting topics.
This is one of those things I've always wondered but never put into words. Now my mind's racing about the possibilities
I do dewatering as my job and this was still pretty cool to watch. Learned alot! We use pumps and coffer dams to bypass water ways, but also install wells around sites to dewater the ground or relieve excess water pressure
Where do we take the water to after dewatering is completed?
Best part of the video was the cabinet cat at the end. What a good little fuzzball.
Hi, long time lurker on your channel. Japan, Taiwan and Philippines recently experienced earthquakes just this week and I think it's a great time to revisit or expand your earthquake related video. A demonstration or two with different intensities, etc. will be helpful.
Thanks for these highly informative videos.
We always experience earthquakes, just that some were a bit harder this time.
Awesome stuff! Thanks man!
What about water structures in earthquake zones? do they have specialized techniques to ensure safety during construction?
Rio-Antirio bridge had her pillars that the base was built in shore, and then they towed roughly in position, and then they were built as normally. The increasing weight due to construction, submersed the pillars until they where set on their own bed.
nope they just hope that nothing bad happens
Beautifully Explained
TH-cam needs more creators & content like you. Very interesting and informative. Great job!
Thank you very much!! I’ve always wondered how this type of construction worked.
You forget one major type of construction, drydock builds. Made out of concrete, steel or other materials its just towed away to a final resting place.
@Rafael If you are curious watch those documentaries:
th-cam.com/video/se26Ux9QD44/w-d-xo.html

Main difference between premade constructions and those made in keson is that it was probably better to made them in dry dock or just impossible to made keson big enough to build it like this (Troll A). Some tunnels are built in dry dock and then submerged (look for Boston Big Dig). I believe that difference is large at least to mention of that type of construction.
@@piotrlenar5652 it is spelled caisson, not keson which is a nonsensical word, not hard to figure out how to spell when spellcheck (should) offer caisson as the proper spelling. And yes many large formats can now be more eaisly precast at a dry dock and loaded out to location and forgo the need for a caisson and thus forgo the dangers of that confined method of casting.
@@Joshua79C Keson (caisson) sorry, it didn't show it as a mistake so i assumed the word is similar to my native language. And it isn't nonsensical you are just unfamiliar with that kind of spelling. And when I check it caisson is french word and you read it wrong as all words in US english borrowed from european languages.
Oddly enough there is a company with that name and I did not mean it is nonsensical in seriousness, Yeah I figured you do not speak English but Google only shows it as caisson for me and could not find alternate spelling in other language (have not even tried it in translator tool to see how it is written in some other languages), but curious to what your native tongue be.
@@Joshua79C en.wiktionary.org/wiki/caisson Bulgarian and Russian spellings of word caisson are familiar to polish witch my native language is. And I speak english or write in it but not too well :)
Do you have a time lapse video of construction of coffer dams?
just search for Cofferdam timelapse and you will find more than enough videos
Bob and vahana?
I was boating in Seattle on Lake Union, the State recently built a new bridge across Lake Washington, I was curious about how these massive supports were built underwater. Perfect explanation! Thank-you
The 1-5 and 520 bridges are actually floating bridges - the two longest floating bridges in the world :)
During my career, coffer dams were quite come. In the early 1900's, my grandfather and great grandfather were divers during the construction of the CPR Bridge in Outlook. Pretty cool standing at the top of the bridge imagining them working so far below.
There is a man who is building an underwater habitat for hampsters. We must fund his reasearch. We must fund Hampture!
This video makes me think about fiber optic cable installation undersea.
I hope you can make a video about it too
Fuad Syawal thick wires are layed out by ships
theres no water drainage for cables. they are assembled on land, applied on a spool on a ship, and then the ship lays out the wire across the ocean.
Really well-presented, great volume, great understandability. I am from the UK so HelloFresh is not an option for me, but it all looks great and American content is fine by me.
I'm a civil engineer from India and u and ur channel is awesome,I really like it.
Stumbled upon this channel by chance, love it.
I have always been directly curious about this exactly! Good explanations! Now I can tell my friends
What a joke
I am glad to see that we aren't the only people with a cat who hangs out in the kitchen waiting for food.
Love these, such a great glimpse into very complicated (on tbe actual engineering level) subjects! Like discovery channel was once but its not dragged out! Would have been cool to had seen these in school, so we would appreciate our cities better.
HI, Thanks for entertaining vids. To concider is also what we use in Finland. Buiding in the arctic areas allows us to freece water and create a coffer dam of ice in the winter, then break the ice on the work site. The ice melts away finally on the spring and doesn't use resources at all. Totally natural.
This is actually a question i forgot to search into, I'm glad that not it only reminds me of it, but also learned of how it actually done. Nice videos and thanks for the knowledge.
Me @ 9 pm: “I think I’ll go to bed early tonight”
Me @ 3:26 am:
TH-cam: you’re welcome
"Stay warm" he says... ROTFL! After a couple hours that wet suit ain't very warm anymore, and dry suits? Not sure if they are better or worse, just different. We also get 2x-3x-4x pay for working inside of a caisson. It depends on the pressures inside. You get paid for compression/decompression time too.
As a coal miner, I normally scoff at the claims of others and how dangerous their job is. But, I must commend your work. If only I got paid extra for ever hole I had to climb into!
Commercial divers use a loose fitting wetsuit called a hot water suit wich has rubber tubes running inside the torso, arms and legs wich carries water heated in a boiler at the surface. Super confortable for long hours in super cold water
Finally a great problem of mine is solved. whenever i am on bridges i think how the pillers are constructed
Lady Engr here. I really liked listening to your voice while explaining this very technical stuff. It creates a believable explanation due to that convincing tone you have. Though I wonder why these 2.5.K dislikes? Are they suppose to be "know better" than your discussions and explanation?
chill, relaxing and engaging would seem to be a tricky combination to pull off, but here we are!
