A caisson is a waterproof structure used in underwater construction, typically made of reinforced concrete, which can be open or closed at the bottom. It is designed to hold back water and soil while allowing workers to excavate below the waterline. A cofferdam, on the other hand, is a temporary structure built to create a dry work environment for construction in or near water bodies, effectively isolating the area from surrounding water. Both are essential for foundation work in bridge and pier construction.

What is the difference between caisson and a cofferdam?
Difference B/W Cofferdam and Caisson:The main difference between a cofferdam & a caisson is that the former is a temporary structure while the latter forms the part of the permanent work. Following factors are to be considered while making a choice between cofferdam & caisson for a particular foundation work:1. A cofferdam becomes uneconomical in cases where the plan area of the foundation work is small as compared to the depth of water. Under such circumstances, a caisson would prove to be the most suitable.2. At places where cofferdam cannot be dewatered successfully, caissons are used. This may be due to the following reasons:a. depth of water,b. nature of soil to be penetrated, andc. permeability of soil below foundation level,3. The process of constructing a cofferdam is greatly simplified in cases of soils which allow easily the driving of sheet piles. The caissons, on the other hand, are useful where obstructions of boulders would prevent the successful driving of the sheet piles.4. For heavy foundation works which are to be provided at a depth of about 12 to 15 metre below the level of standing water surface, caissons would prove to be more economical than cofferdams.
What is the difference between a Caisson and Pile?
A caisson is a retaining structure that is normally water tight that is used to allow construction work to be undertaken under dry conditions below the water table (including below the surface of a river or lake). Examples of when a caisson might be used include on a river bed during the construction of bridge pillars and foundations, or during the construction of a shaft. A pile is a type of deep foundation which usually extends to a significant depth in the ground compared to it's cross sectional area. Piles may be either driven or cast in place. *It should be noted that the industry in North America uses "caisson" interchangeably with "drilled-shaft"; it is not solely used to describe the water-retaining device.

Why did Alfred C. Montin write Caisson?
Alfred C. Montin wrote "Caisson" to explore themes of existentialism and the human condition through the lens of a unique narrative. The story delves into the psychological struggles of its characters, using the caisson—a structure used in underwater construction—as a metaphor for the depths of human experience and the challenges faced in life. Montin's work reflects his interest in the intersection of technology and human emotion, prompting readers to consider the complexities of existence in a modern world.
How would one describe what a Cofferdam is?
It's a temporary enclosure, which holds back water. They are normally used for repair/construction of oil rigs and ships. It is mainly used for easy access of ships hulls for torch cutting.
In engineering what kind of structure is a Caisson?
In engineering Caisson is used to refer to a water retaining structure. Caissons are constructed to keep water out off an area. There are four different types of caissons.

What are the types of caissons?
Caissons are one of the types of deep foundation for construction into some wet or watered site. Three types of caissons are generally found in construction: 1. open caisson 2. bar caisson 3. pneumatic caisson

What does caisson mean?
There are many definitions for a caisson. This can be an underwater chamber that is filled with compressed air for the purpose of creating a working environment such as for construction of a bridge or underwater tunnel. A caisson is also a chest that is used to hold ammunition or a 2 wheeled cart that can be attached to a horse for hauling purposes such as during the civil war times.
What does caission mean?
A caisson is a watertight structure used in construction projects, particularly in areas where water needs to be prevented from entering. It can also refer to a type of wagon or cart used to transport ammunition or stores.
