- A quick overview of how we build underwater structures.
Oceans, rivers, and lakes are often beautiful, but they’re not necessarily convenient places to build things. Yet, many types of the infrastructure we depend on every day, including wharves, bridges, and dams, are founded below the water. How do they do it? On today’s episode, we're talking about different types of underwater construction, including cofferdams, diversions, caissons, and drilled shafts. Whether the construction site is on the bottom of a lake or river, or simply located in the floodplain and only at risk during extreme weather, engineers and construction contractors put a significant amount of thought and consideration into the feasibility and costs of managing this water.

So excited.
exactly!
@@al-aurum2457 Yep!
Ive always wandered
Nailed it. I'm psyched!
I just wondered how hydroelectric dams are built, and bam I see this video in my feed, what a coincidence.
Underwater construction 101:
Step 1: Remove the water.
🤣🤣
Step 2: Carry the water.
There is water at the bottom of the ocean

Dude, Grady: I hope you understand how monumentally important what you do is. I'm not even talking about the engineering (I'm a civil as well, and I work in geotech), rather the conveying of this information in a digestible manner to the public. You rock dude. Glad to see your channel grow.
Might as well post your salary and mortgage payment, you attention seeker.
I come from a construction management background, most of the things you talk about are things I already know. But, I love the way you explain things so simply that it's nice to be able to brush up on my knowledge that has gone dormant over the years from disuse. I always say that an individual cannot ever know enough and it is important to take time to bolster my own knowledge.
You've easily earned my sub. Keep up the great work!
Wholeheartedly agree abundant information
wow
ZzzzZzzzZzz😴😴😴
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.
Yes! Morbidly fascinating!
@CrabApples Bodaciously Bitter Fruit's so you prefer extra deaths over a bridge that doesn’t last as long?
@CrabApples Bodaciously Bitter Fruit's I guess I shouldn’t take the obvious troll bait
@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?
You always pick such interesting topics!
The practical demonstrations and real life examples are what makes this channel so great
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.
ok

Regardless if your in creative, it’s still viable to just spam sponges in the ocean
Damn I had the same joke
ah yes I see you are a man of culture as well
Hahahahahaha
Your wife roasting you in the HelloFresh ad bit is so good :’)
Kinda freaks me out TH-cam always knows what I wanna watch even tho I haven’t searched anything related this
.... fuh real
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 :/
or someone else who has a similar search history as yours, actually searched for this video. so the tube thinks ur brains work similarly.
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
I'm a dockbuilder , local union 1556 NYC , this is what I get to do everyday , 4 generations of tough people.
You guys rock! Thank you for everything you do! I don't think your line of work gets the appreciation it deserves 💗
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.
Cheers!

Its Big Smoke Fool!!!!! ok boomer
I would very much appreciate if you made a more in depth video about this subject. It is fascinating.
"in depth"
I see what you did there.
right? this hello fresh stuff is so exciting!
I sea what you did there
a very constructive comment
I used to think about this when i was 10
This guy looks exactly what you'd expect an engineer to look like.
I agree, the check shirt, bold head and glasses😂😂😂
he looks just like my nephew.. a US Air Force Pilot
He seems very trustworthy too.
Needs a pocket protector.
He's got a wife though. Your move, creep!
Did anybody get sent here from Twitter?
Sleep or Practical Engineering? I think you know which one won. Yay new video!
Sleep
Hey you still up?
Octopuses with hard hats.
Damn.

This guys voice sounds like he has a PhD in Talking.
Writing or talking? Because his voice seems meh.
He may have one in communications
He sounds like that 'how it's made' guy, that's an automatic +100 charisma.
Lmao
? Hes making a presentation.
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.
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.
These videos are all over youtube, fellow viewer.
Is there something I'm not taking into consideration?
Get off the tip
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.

Thank you I have always wondered how they build things in the water. I appreciate the time and effort you put into this to explain it to us. Your graphics and miniature models make it so much easier to visualize.
What came first, the dam or the coffer dam? History's greatest riddle.
The concrete pump came first
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
@@sw33tpwny lmao
@@sw33tpwny we also used windmills smarty
They use Aqua Affinity, Depth Strider and Water breathing potions.

They use a conduit dumbass
Depth strider is a potions?
You just answered so many questions and hypotheses i had for such a long time!
Thanks a lot for all your videos and keep up the good work!
Brilliant engineer who can explain difficult and complex topics to millions, doesn't spend 5 minutes ironing his shirt... Love u, nerd...
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:)
I’ve always wondered this and was glad to see it explained throughly
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.
Yeah we had to wear jackets too. I dont think they would help with anything besides the retrieval of the corpses. Lol
Solution: Wear these high tech protection devices at all times

I can't get over how easy you are to listen to, and you're even easy to look at as you talk. There's something about you as a whole which is sort of zen :)
This guy's amazing. This should be required viewing for everyone. We all need to see what goes into the infrastructure that supports our industrial lifestyle. We need to see how involved, complex, and expensive it is.
Turns out the 40+ hours spent watching Curse of Oak Island weren't a _complete_ waste of my time as the show taught me nearly everything mentioned in this video. It just took a lot longer.
I stopped watching after 10 episodes. Did they ever find anything?
@@erebus3383 they found human remains at something like 190 feet down along with some parchment. I admit this the one tv show I watch regularly, stupid readers digest article that I read when I was a kid.
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.
I passed a sememster of ancient mythologies class with an A without ever studying thanks to Age of Mythologies and I've passed quiet a few history classes with A's and B's by barely trying thanks to Age of Empires, Total War, and a few other games.
@@arthas640 may i ask where you are from? In Germany history tests are more about writing essays about a certain event like how did the weimar republic fail and argue wether it could have been prevented or not, while its sounds like you just need some basic knowledge about history
Thanks.
I've always wondering *_How the heck did they do that?_*
I came here to write the same! haha
Thought u were porn hub
Pornhub
No need to swear man
Check my pornhub intro. Haha
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
TH-cam needs more creators & content like you. Very interesting and informative. Great job!
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?
th-cam.com/video/BHs4CbVDlfU/w-d-xo.html
I have waited so long for someone to explain this! I was always wondering how. Thank you for making this video!
I love this channel. All the things I've ever wondered about I'm learning how they work.
Dang! That was one of the coolest videos I've seen on TH-cam! That was super informative and yet easy to understand. You guys are very good at making informational videos like this! Great job!
Adore your channel, you have a style of presentation that keeps people engaged from start to finish. Your miniature demos help visualize the concepts so much!
I have always been directly curious about this exactly! Good explanations! Now I can tell my friends
What a joke
Leaned a lot.by seeing how physical, mechanical and chemical engineering play a role in allowing for water disperment prior to construction. Thanks for broaching the topic from a historical perspective and bringing TH-cam viewers in line with present day water removal techniques.
This guy is truly amazing and awesome, so much knowledge and gives so much effort and time to make all these content for free. Stay great man.
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 always thought the government enlisted the help of Aquaman.
Love your videos! I watched your videos whilst I was studying mechanical engineering! Your videos are perfect for procrastination (the better kind of procrastinating)!
Grady, you've done it once again. Great work, thank you!
The podcast How Stuff Works recently did two episodes on the construction of the Hoover Dam and it was super interesting. Would recommend
sometimes I wonder If I would have chosen a different career path had I watched videos like yours 5-10 years ago, because you make engineering sound so interesting.
Such fabulous explaining. I would definitely enjoy more of your videos!
wish all engineering lectures were given by this guy
this channel is amazing, you have great skill on simplifying a concept into easy an easy to understand format,
you can easily expand into electrical, mechanical and product engineering,
you already have the winning formula here
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.
Love this guy's channel. So informative from a technical perspective. How anyone can downvote these videos is puzzling to me.
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.
Wow man, a million views and a growing Civil engineering channel. You restored dignity to the so called boring Civil engineering sector, you've really made civil engineering look cool, big ups
Thank you for covering this topic! It's something I've always had in the back of my mind, this vague awareness that I didn't really know what techniques were used for underwater construction. And for some reason, I've never tried to find out before. This was very interesting.
In my childhood days, this is such a mystery for me. So, i say, thanks TH-cam algorithm for ever getting this damn video about underwater buildings get past my recommendations!
For once, you've did the right thing! Kudos
U
Thank you very much!! I’ve always wondered how this type of construction worked.
This channel reinforces my knowledge
I can guarantee you will blow up if you keep up this high quality production and information. Watched this whole video thinking you were one of those multimillion subscriber channels, until realizing you only had 1mil subs. Keep putting in the excellent work and it will pay off.
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.
Awesome presentation and articulate explanation. Keep it up Grady! Cheers!
I loved your video. Thank you for making them.
Awesome stuff! Thanks man!
the music at 0:28 is so satisfiing and relaxing i can hear it all day long
Thank you for not selling out and keeping the ads at the end
Coffer dams... So you're telling me that when I block off the rest of the ocean and then drain an Ocean Monument with Sponges in Minecraft, I'm using this technique?
Cool. :]
*and i did that backwards*
I'm no engineer, but this is actually pretty interesting.
The more you know~
This is exactly what i was looking for, thank you!
2nd vid of yours I've watched. Like them and thanks for sharing.
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.
One of the best engineering channels in youtube. As an engineer, I always check this channel to gain additional knowledge for my profession. Keep up the good work sir!
I always look forward to watching a practical engineering video! Easily one of my favourite channels
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.
Sir,
if you have time,then please make a video on foundations and its construction.
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
This is exactly what I needed to watch at 2am
Me: *should be studying for my computer science exam*
Me: *watching videos on civil engineering instead*
'w';; At least I'm learning. :p
Well, at least it remains somewhat close to engineering. Imagine doing humanities...
You pass
0:22 "Ham Gradey, and this is Practical Engineering!"
Best part of the video was the cabinet cat at the end. What a good little fuzzball.
Interesting video. Battling and triumphing against the assortment of challenges that exist working sub surface is always interesting and fulfilling.
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 was searching for this answer since my childhood,thanks from india, practical engg. Team.
I have worked in a couple of different shipyards and I've seen this a few different places and have been really curious on this thank you
I had no idea I needed to watch this, even if I'm not going to build any dams in the near future or ever.
came here from twitter
tomorrow is my culinary principle test
night before: watching how to build something under water
How was your test
Did you pass?
Legend says he is still testing
Fuck yeah
Did you pass?
This has been fascinating, thanks Grady.

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
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’m hooked. I’ll be binge watching in the future!
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.
How about next video you talk about FOUNDATIONS.
Yeeees, do that one
I am glad to see that we aren't the only people with a cat who hangs out in the kitchen waiting for food.
oh this is EXCELLENT. i've just found your channel and have been watching a lot of your videos over the last few days, and more than once when you've covered a dam or other water-bound structure i've found myself thinking "i wonder how they build in water in the first place?" lo and behold you have a video for that too!! thank you so much for the work and care you put into your videos, they're fascinating and accessible even though i have zero engineering knowledge!
This channel is like a free course in engineering. Thanks!!
