Jan 1, 2005
This paper provides an overview of the advantages and limitations of continuous flight auger (CFA) and drilled displacement (DD) systems compared to other deep foundation systems, along with a summary of important considerations for selection and design. Geotechnical and project considerations are described which favor the use of CFA and DD piling, and also which may be problematic for this type of construction or which may limit the practicality and competitive advantages. A brief summary of design methods for axial and lateral loading is included.
