I have updated our calendar for 2010 to include many events in the geotechnical and foundation engineering world that may be of interest, plus known speaking/teaching appearances by Dan. I’ll put in a plug for the events calendars and listings for ADSC, DFI, Geo-Institute, and PDCA. I get most of my information from them.
Some, but not all events,(in addition to my previous post) are:
First, Tony Marinucci, P.E. joins the staff at ADSC. Here is the release from ADSC highlighting Tony’s career and his new position.
Marinucci Joins ADSC Staff
We are pleased to report that Antonio Marinucci, P.E., MSCE, MBA, is joining the ADSC headquarters staff in a full-time capacity as he completes his Ph.D. studies in geotechnical engineering at the University of Texas at Austin. Tony comes to this new post with many years of experience working for geo-construction specialty contractors, a major general contractor, and geotechnical engineering firms in a variety of capacities including project management and deep foundation and anchored earth retention design. His credits include participating in many geo-engineering and construction research projects. Somehow, while working full and part-time in the industry, he managed to complete graduate degrees in engineering and business. He is the current Secretary of the Geo-Institute’s Deep Foundations Committee, as well as holding the same position for the G-I’s Soil Improvement Committee. He has been an active volunteer and committee member for many ADSC, ASCE, and DFI initiatives. Among his many volunteer service achievements was serving as the President of the ASCE Student Chapter while attending the University of Rhode Island. In addition to all of his volunteer service, he has authored or co-authored twelve published technical papers, and several feature articles that have appeared in Foundation Drilling magazine. One of his most interesting and challenging geo-construction experiences was working as a staff engineer for Modern Continental Construction in a variety of capacities on Boston’s “Big Dig” project. A member of four leading National Honor Societies, he was also the recipient of an ADSC Civil Engineering Graduate Study Scholarship.
You can see by this abbreviated description of Tony’s stellar career that he will be an excellent addition to the ADSC’s professional staff. His responsibilities will include serving as an in-house technical resource, coordinating ADSC’s eight regional chapters, assisting in the associations technical education and field training programs, working with the association’s 18 technical and organizational committees and task forces, overseeing the association’s membership recruitment and retention programs, and assisting ADSC CEO Mike Moore in a number of related endeavors.
Second, the PDCA is soliciting nominees for the 2010 Project of the Year award. There are several categories based on project location and size. Projects must have been completed in 2009. Deadline for entries is February 26, 2010.
The PDCA would like to inform you about the 2010 "Project of the Year" Award competition.
The PDCA is dedicated to acknowledging the hard work, ingenuity and commitment that goes into each project where driven pile are used i a deep foundation or earth retention system, or utilized to solve foundation problems. This PDCA tradition recognizes excellence in driven pile projects completed by PDCA members in good standing.
Through the "Project of the Year" award, the PDCA has the distinguished opportunity to continue its long-standing and consistent commitment t recognize those PDCA members who demonstrate excellence in the process of providing solutions, services and products to the needs of the deep foundation and earth retention environment.
Project entries must feature projects completed in 2009. Projects entries will be awarded in two entry categories and three dollar volume categories. The two entry categories are distinguished by either "Land-based" or "Marine-based" projects. The dollar volume categories are Less than $500,000.00, $500,000.00 – $2 Million, and Greater than $2 Million. Price ranges are based solely on the dollar volume of the piling contract associated with the project.
The PDCA is asking each of its members to consider submitting a project worthy of this prestigious PDCA award. Entry Forms will be made available on the PDCA website by Monday, December 7, 2009.
The "2010 Project of the Year" entry deadline is Friday, February 26, 2010. Late entries will not be considered.
Winning entries will be announced during the 2010 PDCA Annual International Conference and Expo, Coeur d’Alene Golf and Spa Resort, Coeur d’Alene, Idaho during the PDCA Business Luncheon on Saturday, May 8, 2010. PDCA will NOT reveal the winning entries prior to the luncheon.
Winning entries will also be featured in the following editions of Pile Driver magazine and on the PDCA website.
PDCA looks forward to receiving your entry – GOOD LUCK!
Third, registration is open for the Geo-InstituteGeoFlorida 2010 conference in West Palm Beach, Florida. There will be short courses, a technical program, student competitions, exhibits, honoring our heroes, and all the usual events at the annual G-I meeting. Click on the logo to go to the conference website.
Lastly, abstracts are now being accepted for consideration of the 2011 Geo-Institute meeting Geo-Frontiers 2011 in Dallas, Texas. Abstracts are due March 8, 2010. Click the logo to get to the conference website for submission information.

I am slowly learning and working on getting DBA involved in using some of the social media tools that are very quickly becoming popular means of communicating. DBA has a Facebook Page where you can become a Fan of DBA and see what we are doing. You can also follow us on Twitter. This blog will feed to both of those locations.
One area of work we are frequently involved in is data analysis and evaluation of lateral load tests performed by the Statnamic testing device (learn more at the website of Applied Foundation Testing). The mathematics involved in the data reduction can be quite formidable as you interpret the dynamic load-response to an equivalent static load-response. Regardless of the math behind it, watching a test can be pretty cool. It is a whole lot of work for a brief moment of load, but in some situations it can be more economical than a traditional load test.
The video below is from a test on 170-foot long, 32-inch outside diameter steel pipe pile with 0.75"-inch wall thickness. The pile was filled with concrete that included an instrumented rebar cage.
Steve just can’t get enough of the state of Louisiana. Now that the Audubon Bridge foundations are complete, he needed an excuse to get back and found himself in the Crescent City observing production shaft base grouting at the Huey P. Long Bridge project. Here area few more good construction photos to supplement my previous post.
Here is an interesting story in the New Orleans Times-Picayune about the bridge project explaining how they are widening the bridge.
Dan, Paul and Erik were at the 34th Deep Foundations Institute Annual Conference in Kansas City last month. Dan was one of the keynote speakers where he presented our paper on the drilled shafts for the Missouri River Bridge on the kcICON project in Kansas City. Paul was also able to receive the Special Recognition Award (honorable mention) in the annual project awards for the pile foundations at the Biloxi Bay Bridge project.
Yes, you read that right – the last drilled shaft has been installed on the John James Audubon Bridge near New Road, Louisiana. The project has been quite an adventure for us, especially Steve. He spent the most time on the site during shaft excavation, tip grouting, load testing, and even pile driving. Robert got to spend a fair amount of time, too, over the last couple of years. Paul was even lucky enough to make a couple of trips.
The shaft construction was concluded with one last O-cell test on Shaft 3W South. Dan was present for the last load test which went fabulously well.
If you are going to the Geo-Institute congress GeoForida 2010 next February in West Palm Beach, you can hear Steve present the paper he and Dan wrote on the tip grouting and load test program.
The bridge is still under construction, of course, and will be an awesome structure when completed. It was an exciting project for us to be a part of the team. We’ll have a project summary posted in the near future to highlight the details of the foundations. For now, you will have to be satisfied with the slideshows below (in reverse chronological order) from some of our visits this summer and fall.
Load Test at Shaft 3W South – October 2009
Excavation of Shaft 3W South – September 2009
Shaft Grouting and other Construction – June 2009
Shaft Excavation, Pile Driving, and Cofferdams – May 2009
