Last week’s International Foundation Congress and Equipment Exposition was a huge success! Dan gave a keynote address on Tuesday on managing risk in deep foundations within the design-build delivery model. Paul, Erik, and I also had papers to present. The technical sessions were excellent, the indoor exhibits were excellent, and the outdoor exhibits of foundation equipment were outstanding! The ADSC, Geo-Institute, and PDCA were the co-organizers of the event. A big hats off to all of the staff of all three organizations that made the event a huge success! Thanks and “atta boy” go to Mohamad Hussein, P.E. (Conference Chair) and to Dan (Technical Program Chair) for all of their work, as well as the rest of the organizing committee.
I have also blogged about the conference here at GeoPrac.net.
Here are some pictures of the outdoor exhibits:
  
There were over 300 papers included in the conference. The proceedings were published as three Geotechnical Special Publications:
GSP 185: Contemporary Topics in Deep Foundations
GSP 186: Contemporary Topics in In-Situ Testing, Analysis, and Reliability of Foundations
GSP 187: Contemporary Topics in Ground Modification, Problem Soils, and Geo-Support
The editors, Magued Iskander, Ph.D., P.E. (Polytechnic Institute of New York University), Debra Laefer, Ph.D. (University College Dublin, Ireland), and Mohamad Hussein, P.E. (GRL) all had their work cut out for them.
I have added all seven papers authored by DBA team members to our site. The links are below, or you can go to our Publications page.

Erik and Dan have published a final report entitled “A Method for Predicting Mobilization Resistance for Micropiles Used in Slope Stabilization Applications”. The report was prepared for the Joint ADSC/DFI Micropile Committee. This version has been submitted to the committee for review and comment. From the report:
The primary objective of the work described in this report has been to identify a method for predicting the resistance provided by micropiles used for slope stabilization that: (1) is consistent with the available field performance data, and (2) takes advantage of the improved knowledge gained from the performance observed in previous implementations. This objective has been met through review and analysis of case histories with well documented performance measurements, analysis of stability and load transfer for these case histories, development of an improved technique for predicting the resistance provided by micropiles, evaluation of the proposed technique as compared to available field performance measurements, and, finally, use of the technique to demonstrate its application for a hypothetical case and to demonstrate the implications of the technique for design of slope stabilization schemes with micropiles.
This report should be a great resource to practicing geotechnical engineers considering micropiles for slope stabilization.
Financial support for this work was provided by a grant from the H.B. Williams Industry Advancement Fund of ADSC: The International Association of Foundation Drilling.
