Papers by Dan, Steve, and Tim that were included in the GeoFlorida 2010 conference have been uploaded to our Publications page. Dan and Steve co-authored a paper on the test program of the base grouted drilled shafts for the Audubon Bridge. Tim co-authored a paper with Willie NeSmith of Berkel and Company Contractors, Inc. on plate load testing of displacement grout columns. Dan was also a co-author with several others on a paper on jet grouting for improved pile lateral capacity.
With all of us visiting construction projects across the country, occasionally we take a photo that appears to be somewhat “artistic” – maybe the lighting (or lack of), or the aspect. I have assembled a few such photos submitted by DBA engineers in the first installment of the DBA Artistic Construction Photo Contest. Included in this installment are such items as: “Daybreak on Night Shift at JJA” and “Fountain” by S. Dapp, the series “Evolution” by P. Axtell, “GI Rig at Sunset” by T. Siegel, and “Piles in the Mist” by R. Thompson. This first volume has more photos of mine than others, but we’ll work on better balance in future volumes. Feel free to “vote” for your favorite in the comments. I’ll try to update periodically as we have more “worthy” photos!
The Spring 2010 issue of Deep Foundations from the Deep Foundations Institute includes an article by Dan and Paul (with a little help from yours truly!). The article is based on our paper presented by Dan at the 34th DFI Conference on Deep Foundations last October in Kansas City. The kcICON project continues to roll along. Check out their Facebook page where they have lots of photos and links to their YouTube page. They recently completed the widest bridge deck pour ever for MoDOT. Go to our Publications page to see the article, or click the image below.

It has been a little while since we last visited the John James Audubon Bridge site in New roads, Louisiana. My how things have changed! I just have a couple of pictures of the piers from January – it is really looking like a bridge now! For frequent updates, check out the webcam and the photo albums on the project web page. The web cams have a really cool time lapse button that shows you a time lapse loop of the pier from the beginning of construction. UPDATE (2/28/10) - I added 3 new photos to the slide show that were taken this last week. At that time the piers were at lift 21 and were about elevation +335 feet (the top of the sheet piles at the foundation level are about elevation +50 feet).

DBA is on the successful team that was awarded the contract for the new Mississippi River Bridge in St. Louis, Missouri. The project is a joint project of MoDOT/IDOT with MoDOT being the lead agency. HNTB is the lead bridge designer for the new cable-stayed bridge carrying I-70 over the river. The bridge is one part of a larger project that also includes the Missouri North I-70 Interchange, the Illinois I-70 Connection, and the Illinois Tri-level Exchange. From the project web site:
The wining contractor team is Massman/Traylor Brothers/Alberici Constructors. DBA’s role was to help prepare an alternate concept for the drilled shaft foundation design which will include load test measurements. We anticipate construction to begin in March with load test shaft. An overview of the bridge is here. The press release for the award of the main bridge is here.
An article on the kcICON bridge project was published in the November 2009 issue of Roads and Bridges magazine. The article was written by Pat Cassity, P.E. of Parsons Transportation Group, Brian Kidwell, P.E. of MoDOT, and Pat Byrne, P.E. of Massman. The on-line version is here. I have also posted a PDF on the kcICON page our Consulting Projects page you can access by clicking the image below.
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. More photos from the conference are at this link.
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
