Not sure of the wording of your question. A drilled casison foundation is typically constructed with an auger that digs a hole in the earth. Reinforcing steel MAY be placed in the hole, which is then poured full of concrete. These may be small- about 8 inches in diameter for a deck on a house- or 10ft wide and 85 feet deep for a bridge we built in CA.

What is a bell bottom pier concrete footing?
Piers are drilled when the ground conditions at the surface are not good for supporting a foundation. An engineer determines from an engineers soil report where the bottom of the pier needs to be. The driller has an attachment that will drill a 36" bell bottom with a shaft size of 12". The pier is drilled, the bottom formed, steel cage dropped in the hole and then filled with concrete. These piers will be placed below the grade beams of the slab.
What is the item called a caissons used for?
A caisson is a watertight container necessary for working on piers, for example. As the pier is constructed, water may be pumped out of the caisson keeping the designated work area relatively dry.
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 is the purpose of caisson foundation?
caisson foundationsare foundation systems created by drilling holes and filling them with concrete. A caisson pile is a cast-in-place pile that has a hollow tube driveninto the ground. The earth is excavated from the tube, and concrete is poured into the tube. Some caisson piles are flared out at the bottom to create a larger bearingsurface. These are sometimes called bell caissons.The purpose is to extend the foundation through soils that are not capable of load-bearing capacity.The caissons may be attached to grade beams and/or retaining walls or structural beams as intended and described by your engineer.
Is a pier a pile foundation?
pile is the steel layer and pier is the outer most layer'
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.

What is a caisson?

How does a caisson differ from a column?
A caisson is what you make to keep water away while you construct a column in a river or lake.
How wide do you excavate for a foundation?
That depends on what type of foundation you're going to build, whether it be block, pier, poured wall, or earth form. Please indicate the type you are inquiring about.
