Continuous Flight Auger (CFA) piles are used to sustain the axial and lateral force from structures such as roadway embankments, bridge footings, and building foundations, to name a few.

CFA piles have been used in the U.S. commercial market for years but have not been used frequently for support of transportation structures in the United States. This underutilization of a viable technology is a result of perceived difficulties in quality control, and the difficulties associated with incorporating a rapidly developing (and often proprietary) technology into the traditional, prescriptive design-bid-build concept. Recent advances in automated monitoring and recording devices will alleviate concerns of quality control, as well as provide an essential tool for a performance-based contracting process.

This course provides descriptions of the basic mechanisms involving CFA piles, CFA pile types, applications for transportation projects, common materials, construction equipment, and procedures used in this technology. Recommendations are made for methods to estimate the static axial capacity of single piles. A thorough evaluation and comparison of various existing methods used in the United States and Europe is also presented. Group effects for axial capacity and settlement are discussed, as well as lateral load capacities for both single piles and pile groups. A generalized step-by-step method for the selection and design of CFA piles is presented and quality control (QC)/quality assurance (QA) procedures are discussed.

An Allowable Stress Design (ASD) procedure is presented in this course since resistance (strength reduction) factors have not yet been calibrated for CFA piles for a Load Resistance Factored Design (LRFD) approach. Several example problems will be discussed to aid the student in understanding the design requirements. The student will learn how to solve for side-shear strength, bearing capacity, reinforcement requirements, as well as solve other ancillary equations related to designing CFA piles.
