Augered Cast-in-Place Pile Quality Control
Rudolph P. Frizzi, P.E.
The current trend of increasing augered cast-in-place (ACIP) pile diameter, length, and load carrying capacities demonstrates improvements in installation equipment, increased acceptance, and that quality control is being successfully implemented by the parties involved in the ACIP pile construction process. Quality control is essential for ACIP piles since 24- to 36-in-dia (610- to 915-mm-dia) piles are currently being constructed to sustain design compressive loads of 800 to 900 kips (3555 to 4000 kN). This paper presents a summary of ACIP pile quality control procedures and methods beginning in the design and bid process, through ACIP pile installation, to post-construction. The results of a recent survey of contractors, engineers, equipment suppliers, and researchers routinely involved with ACIP piles in the United States, Europe, and the Middle East are included to address current trends in ACIP piles and quality control.
