Call for Papers/Presentations for STGEC 2012

A Call for Papers/Presentations has been issued for the 2012 Southeastern Transportation Geotechnical Engineers Conference (STGEC). The conference will be held October 22-25, 2012 in Richmond, Virginia.

VDOT (Virginia Department of Transportation) will be hosting the 2012 STGEC in Richmond,
Virginia. As part of this conference, we are looking forward to a variety of presentations that
demonstrate feasible, state-of-the-practice and innovative solutions to today’s challenges in
transportation geotechnical engineering.

Download the Call for Papers/Presentations here. Abstracts are due June 8th.  Contact Contact Carl Benson (Carl.Benson@VDOT.Virginia.gov) or Kwame Adu-Gyamfi (Kwame.Adu‐
Gyamfi@VDOT.Virginia.gov) for more information.

ADSC Lawrenceville Site Research Report Available

The ADSC SE Chapter has been sponsoring a research project on rock-socketed drilled shafts in the Southeast U.S.  The project started in 2008 with testing conducted a the first site in Nashville, Tennessee in 2009.  The Lawrenceville site was tested in 2011 and is the second site for the project.  The report for this site was recently completed and is available for distribution.

Click this link to get the report for the Lawrenceville site.

More information on both this site and the first test site in Nashville, Tennessee can be found at the blog of the project researcher, Dan Brown and Associates, PC:

NCHRP Synthesis 418–Developing Production Pile Driving Criteria From Test Pile Data

nchrp_syn_418 - pile criteria from test pilesThe Transportation Research Board of the National Academies has published: NCHRP Synthesis 418–Developing Production Pile Driving Criteria From Test Pile Data.  This synthesis provides a survey of the current practices used by transportation agencies to develop pile driving criteria, with special attention on the use of test pile data. The report covers issues related to developing driving criteria, the current practices used by the responding agencies, recommended useful practices that were identified, along with descriptions of the practical approach several agencies use to integrate a range of technologies to develop pile driving criteria under typical conditions. The information collected indicates that practices used by transportation agencies to develop pile driving criteria for production pile installation can be described as highly variable in terms of the level and sophistication of the testing performed.

ADSC Lawrenceville Test Site – Field Demo Day and Prediction Contest!

The ADSC is working on the second in a series of test sites around the Southeast U.S. for a research project to generate load test data for rock sockets in this part of the country.  Two test shafts were installed the week of July 26th at the yard of Foundation Technologies, Inc. One included a rock socket to attempt to test side and base resistance in the rock socket.  The other shaft was drilled to "rock auger refusal" to attempt to test side resistance in the partially weathered rock (locally termed PWR) and base resistance at "rock auger refusal".  In the Piedmont area, the highly weathered upper rock zone is commonly called PWR.  Another common usage is “rock auger refusal” to define where “hard rock” begins.  It is thought that designers may be overly conservative with base resistance values at “rock auger refusal”.  Hopefully this test will provide useful data concerning this issue.

A prediction contest for this second test site will be held similar to the one held for the first site in Nashville, Tennessee.  Contestants are encouraged to download the information linked below and then submit their predictions of unit side resistance and base resistance that will be measured by the O-cell tests. The winner will be announced at the field test and demonstration day on site, as well as published in this blog along with all submitted predictions.

Testing will occur during a field demonstration day on August 18th, 2011.  The Field Day will consist of a brief lecture by Dan Brown regarding drilled shaft load testing in general and this testing program specifically.  This will be followed by lunch.  After lunch, Loadtest, Inc. will be performing the two O-cell tests.

Information to include the test shaft configurations and exploratory boring data can be downloaded here.  Photos of the excavations will be posted as soon as possible after the excavations are complete (check the project web page soon after August 1st) to assist in making predictions.

The contest entry form along with instructions for submission can be downloaded here.

All predictions must be submitted by the close of business, August 12, 2011.
