Abstract:

Auger-cast-in-place (ACIP) piles are created when an auger the diameter and length of the desired pile is drilled into the ground. Concrete is pumped through the central axis of the auger as it is withdrawn, pulling up excavated soil as concrete fills the shaft. Steel reinforcement is placed in the still-fluid concrete. The entire process is conducted blind and instrumentation is rarely added to the reinforcing steel giving no way to verify the two key quality control elements that help assure the expected load-bearing performance of the pile: the consistency of the pile’s diameter along its length and the positioning of the reinforcement. Because of this, the Florida Department of Transportation (FDOT) restricts the projects in which ACIP piles can be used, despite the advantages of this construction method.
