What do you mean by caisson foundation?
Caisson foundations, also known as pier foundations, are prefabricated hollow substructures designed to be constructed on or near the surface of the ground, sunk to the desired depth and then filled with concrete, thus ultimately becoming an integral part of the permanent structure.
How is caisson foundation construction?
It is a form of deep foundation which are constructed above ground level, then sunk to the required level by excavating or dredging material from within the caisson. Caissons (also sometimes called “piers”) are created by auguring a deep hole into the ground, and then filling it with concrete.

What is the difference between drilled shaft and caisson?
Drilled shaft casings are also referred to as caissons, bored piles, or drilled piers. Drilled-hole shafts like this are deep-foundation solutions capable of bearing large loads with high lateral resistance and are often designed for bridges and other large structures. These shafts have economic benefits as well.
