Bridges are marvels of engineering, particularly when they are built over deep water.
Bridges are not only aesthetically beautiful structures, but they are also marvels of engineering and nowhere is this more true than when they are built over water. This brings us to the question of how bridges are built over water, particularly deep water.
When the water is shallow, construction is easy. A temporary foundation is made on which piers are built to support the upper structure.
But what happens when the water is deep? This process requires advanced engineering that is nothing short of magic.
There are three main methods for building bridges in deep water: battered piles, cofferdams, and caissons. Each of these comes with each own advantages and complications.
How do engineers decide which technique to pick? These are important decisions that can only be made by experts. They depend on the condition of the site and the technology available.
What are the details of each method? We won't tell you that. You have to watch the video for that. We will tell you that watching this video will leave you with a thorough understanding of how bridges are built over deep water.
