International Foundation Congress and Equipment Expo ’09
Mark you calendars now for a really big geotechnical engineering and foundation construction “mega-event” next year – The International Foundation Congress & Equipment Expo ’09. The Geo-Institute of ASCE, the ADSC, and the PDCA are the lead organizations for the event. Many other organizations are also Cooperating Organizations.
The International Foundations Congress and Equipment Expo ’09 (IFCEE09) will provide a spectacular and comprehensive Congress. It combines the International Association of Foundation Drilling (ADSC), the Geo-Institute of ASCE, and the Pile Driving Contractors Association (PDCA) 2009 annual meetings, and will bring together varied USA and worldwide industry organizations.
As part of the technical program, engineers, foundation contractors, equipment manufacturers, suppliers of tools and services, and researchers will discuss the latest technological advances in the foundation and earth retention industry. The extensive outdoor large equipment exposition and indoor displays provide attendees an opportunity to examine the tools of foundation construction, and are an additional incentive for constructors and engineers to attend this mega-event. This expanded program builds on the highly successful 2004 Geo-Support conference and equipment exposition held in Orlando, FL.
The conference will be at the Buena Vista Palace Resort and Spa adjacent to Downtown Disney at Walt Disney World, Florida. In addition to a full program of keynote speakers, technical paperas, case histories, and panel discussions, the largest equipment exposition devoted to the foundation industry will also be held.
Information on the Call for Papers is here. Abstracts are due April 30, 2008.
Information on exhibits and sponsorships is here.
We will have a link to the conference website at the top of our right side bar until the conference date.
Conferences, seminars, and other useful links
Make sure and check the links on our left side bar for information on upcoming conferences, meetings, and seminars. We try to list all of the major events of organizations like the Geo-Institute of ASCE, the ADSC, the PDCA, and the DFI.
Also, check out the changes in geotechnical engineering related to transportation projects coming out in Arizona at Geoprac.net. From Randy’s post:
There are some significant changes being made to the state of the practice in geotechnical engineering in Arizona. NCS Consultants, LLC has prepared three policy memoranda for the Arizona Department of Transportation or ADOT that have been issued to consultants all over the State. These memos are on the topics of bearing capacity and settlement of spread footings and retaining walls, the design of drilled shaft foundations in gravelly soils, and the preparation of drilled shaft axial capacity charts for use by bridge engineers.
Randy does a good job of scouring the web for geotechnical related items. A link to his site is on our left sid bar and we have a feed to his posts on the right side bar.
While I am on the topic of resources, we also have a link to Geoengineer.org, another resource website for the geotechnical engineering community. A link to the site is on the left side bar, and links to their latest newsletters are on the right side bar.

Slope Stabilization Method with Micropiles – A report for the ADSC/DFI Joint Micropile Committee
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.
A copy of the report can be downloaded here.
JJA Bridge in ENR.com article
An article entitled “Historic Cable-Stayed Link Taking Shape in Louisiana” about the construction of the John James Audubon (JJA) Bridge in Louisiana is on ENR.com here. The drilled shafts actually extend much deeper than indicated in the article, for what its worth. I think they were only talking about the permanent casing, not the entire drilled shaft.
Updated – GEC No. 8: Design and Construction of Continuous Flight Auger Piles – It’s Finally Here!
11/30-07 Update! – GEC No. 8 is now up on the FHWA web site. You can download it here.
Yes, folks, GEC 8 is finally complete! The publication version of Geotechnical Engineering Circular No.8: Design and Construction of Continuous Flight Auger Piles will soon be available from the FHWA Geotechnical Web Site. If you want an official sneak peek at GEC 8, just click here to get the PDF (approx. 10 MB). This circular is part of FHWA’s efforts to implement the use of CFA piles as a viable foundation alternative for transportation structures. We’ll post a notice when GEC 8 is on the FHWA web site.
Designing Drilled Shafts in Loess – Article posted
I have added a copy of a recent article entiteld “Designing Drilled Shafts in Loess” that Dan was one of several co-authors in the August 2007 Edition of Foundation Drilling from the ADSC. The article is a preview of some research by the Kansas DOT through the University of Kansas on designing drilled shafts for lateral loading. This particular project is investigating the behavior of laterally loaded shafts in loess.
