USE OF PILE AS PIER Having the pile (where piles are used) extend above grade as the pier would simplify and speed up foundation construction. A drilled pier is a deep foundation system that uses a large diameter concrete cylinder constructed by placing fresh concrete and reinforcing steel into a drilled shaft. It is a prefabricated hollow box or cylinder sunk into the ground to some desired depth and then filled with concrete thus forming a foundation. Among them are drilled piers, cast-in-drilled-hole, bored piles and caissons. The concrete piers provide excellent resistance to vertical and lateral loads, and can be constructed with readily available materials.
