scope:

This Practice supplements PIP STS02465 and proveds assistance to the engieer in the preparation of contract documents for furnishing and installing augered cast-in-place piles.

This Practice is modeled on the DFI Augered Cast-in-place Piles Manual.  For additional information, refer to that manual and also to the DFI Inspector's Guide to Augered Cast-in-Place Piles.

This Practice does not describe requirements for lateral displacement of drilled displacement piles, also known as augered cast-in-place displacement (ACID-D) piles.  ACIP-D piles may be a good substitute for augered cast-in-place piles in some soil types/conditions.  Because of reduced or eliminated spoils, ACIP-D piles may be a good choice in contaminated soil conditions.  However, the different types of proprietary ACIP-D piles may be more or less suited for different soil conditions.  Appropriate engieering, including geotechnical engineering, is required.  DFI is developing a practice manual on ACIP-D piles, and the Federal Highway Administration is developng a manual on augered cast-in-place piles that addresses ACIP-D piles.  Both Manuals are due out in 2005.

Purpose

This Practice provides recommendations for the design and installation of augered cast-in-place piles for use by the engineers and specifiers of augered cast-in-place piles.
