A cylindrical shaft is excavated, reinforcing steel is placed in the excavation and concrete is placed to form the shaft. A drilled shaft (caisson) is often installed in the construction.
Drilled Shafts Or Caisson Foundation. They are used to support structures with large axial and lateral loads by drilling cylindrical shafts into the ground which are then filled with concrete. The casing is a steel plate rolled and welded to form a large diameter pipe.

Drilled shaft casings are also referred to as caissons, bored piles, or drilled piers. The additional capacity is a result of the size of the drilled shaft. Caissons shall not be out of plumb more than 25 mm (1 inch) in 3000 mm (10 feet) for the full depth. Extent of caissons into bedrock is shown on drawings, including locations, diameters of shafts, diameters of bells where required, estimated bottom elevations, and details of construction.
