How Underwater Structures are Built? Cofferdam Explained!

When construction needs to take place somewhere that is submerged underwater, engineers use a series of large driven piles into the waterbed called cofferdams to create a dry workplace.

In terms of geotechnical engineering, the process isn’t as simple as just pushing walls into the ground, engineers have to carefully design the structure to not flood and keep the workers inside safe from collapse.

Civil Construction Engineers are simply great!

In My youth, (I’m now 64) I knew a Concrete Engineer who had to design a Concrete which could be poured in the Extreme Heat Conditions found at the Woomera Rocket Range in Outback Australia, without becoming prematurely dry and becoming brittle.

Then he had to design a Concrete which could be poured underwater and which would then repel the Water and Set as required.

Wow that's a great engineering work

Humans capable of incredible engineering, and people still give credit to the aliens for the pyramids

Master planing for under water construction

That is wonderful, I am also civil Engineer😶🌟

How are the pipes even driven into the water in the first place? Can cofferdams be built only at the edge of the water where it's shallow?

In October of 1978 the largest single wall coffer dam collapsed in Lake Keowee, SC killing 7 people. My company spent 16 days burning their bodies out.

Video 3:58, is this.. the three kings of christmas crib 😍👍

Could you explain how they did it without machinery? Tower bridge London
Was built in the late 18 hundreds

What do oil well pumps have to do with this?

[pambudidotti]

I'll bring my crush to bridge and telling her how it's been made to look smart 😎

[chadcasale]

Crazy how we are still using techniques developed thousands of years ago.

[JonathaninEssex]

How do they make the concrete waterproof?

Yeh but how they do it before moden vehicles and technology....easy with moden stuff

May God bless you all brother's for long life Amen ☝🏽

What the heck I don't need the history of that damn I want how to build and use it in waters

[mcjiehembile]

Do they consider underwater habitat before doing it? What happens to the fishes and Coral?

[satyamsingh-tpmw]

I didn't even know that word 'caisson' exists untill that meme popped in my feed...
