Two New Technical Manuals From DFI

The Deep Foundations Institute (DFI) has announced the publication of two new deep foundation reference manuals.   Excerpts from the announcement for both manuals are below.  Both manuals are available for order from DFI by clicking the links in the titles.

Guideline for Interpretation of Nondestructive Integrity Testing of Augered Cast-in-Place and Drilled Displacement Piles

This guideline provides practical guidance for the interpretation of nondestructive testing (NDT) of the integrity of augered cast-in-place (ACIP) and drilled displacement (DD) piles.  …  This guideline supplements DFI’s two primary publications on ACIP piles: Augered Cast-in-Place Pile Manual (2003) and the Inspector’s Guide for Augered Cast-in-Place Piles (2010). This guideline was developed to provide 1) more detailed explanations of the various test methods available, 2) guidance on interpretation of the results, and 3) some typical examples of the data and interpretation.

This guidance document is intended to assist geotechnical engineers, pile designers, and contractors in analysis, design, and testing of piles and drilled shafts for lateral loads. … … This document discusses the background of different analytical and testing procedures and presents the recommended methods for analysis, design and testing of piles for lateral loads.

Technical Note on ACIP Pile Load Testing

A technical note by Tim that appeared in the December 2010 issue of the DFI Journal has been added to our publications page.  Tim’s note examines some issues related to axial load testing of augered cast-in-place (ACIP) piles, also know as augercast piles or CFA piles, that are not covered in ASTM D 1143/D 1143M-07 Standard Test Methods for Deep Foundations Under Static Axial Compression.  Specifically, load hold time, unload-reload cycles, and fluctuations in incremental load are discussed as they relate to load testing for determining axial capacity or axial load distribution of ACIP piles.  Details of instrumented ACIP pile load testing are also covered.
