St. Croix Bridge Construction Starts with Official Groundbreaking

St Croix Aerial Rendering

Earlier this week, officials from the Minnesota and Wisconsin departments of transportation (MnDOT and WisDOT) met for an official groundbreaking ceremony on the projected $629 million bridge and highway project that will connect Oak Park Heights, Minnesota, to St. Joseph, Wisconsin, just south of Stillwater, Minnesota, as highlighted in yesterday’s edition of The Minneapolis St. Paul Business Journal.  The new bridge will replace the 80-year-old Stillwater Lift Bridge and relieve traffic congestion in nearby Stillwater.

DBA has been retained by MnDOT as the lead geotechnical consultant and foundation designer for the extradosed river bridge.  Last summer, DBA aided MnDOT in the design and oversight of a load test program described in my blog post, “DBA Wraps Up Load Test Program and Proceeds with Design on St. Croix Bridge.”  Following final design, which took place over the fall and winter, construction of the foundations will begin next week with the installation of a technique shaft.  DBA will participate in construction as well, providing construction observation and review of the technique shaft and at least one shaft at each of the five production piers.  Edward Kraemer & Sons, Inc. of Plain, Wisconsin, has been selected as the general contractor for the foundation contract with sub-contractor Case Foundation Company of Chicago, Illinois, performing the drilling.  The extradosed bridge will feature five main river towers, each resting on two footings supported by a 4-shaft group of 8.5-foot drilled shafts, socketed 25-feet or more into sandstone bedrock.

I hope to have some more updates soon with some pictures following my upcoming site visits to observe the construction operations.  In the mean time, you can stay updated by visiting the MnDOT project page and watching the “action” live via the construction webcam.

Busy Fall Speaking Schedule for DBA

The months of September and October will be busy for several DBA team members speaking at a variety of conferences and events. Dan Brown and John Turner will be speaking at the ADSC/DFI Drilled Shaft Seminar and Field Day in Denver September 12 and 13. Dan will be giving the 4th Annual Osterberg Memorial Lecture at the DFI Educational Trust dinner being held on the evening of the 12th. Dan and John will be speaking mostly on construction issues during the seminar.

Back in April, Dan received news of a special honor…he was elected to membership in The Moles, a prestigious organization composed of individuals now or formerly engaged in heavy underground construction (tunnel, subway, foundation, marine, etc.). The organization has a limited membership (538 Active Members) and one must be nominated by a current member.

The Moles, a fraternal organization of the heavy construction industry, is the most prestigious organization of its kind in the world. Moles members are leaders in their profession who are dedicated to promoting the industry and supporting their colleagues through outreach programs and networking opportunities.

In addition to their fraternal activities, a significant mission of The Moles is to encourage young people to participate in heavy construction and its related fields.  The Moles have several educational programs, cooperating with 20 colleges and universities, to further that objective, including an annual Students Day tour of construction projects, scholarships, student awards, and a Career Connection program.

Dan was elected along with 16 others this year.  A list of the new Moles can be found in the April 2012 issue of Holing Through, the news bulletin of The Moles (available on their website).  The new members were inducted in May. 

Congratulations Dan!!!!!

Papers from ADSC EXPO 2012–Drilled Shafts and Other Drilled Foundations

ADSC EXPO 2012, San Antonio, Texas

2012-ADSC-EXPO-Technical-Conference-[2]

There were several of us presenting at the ADSC EXPO 2012 in mid-March: Dan, Erik, Robert and Tim. The EXPO is always a great event (occurs every 3 years) where equipment manufacturers and dealers bring out all of the big equipment (as Dr. Dave Elton at Auburn has been known to say: “It’s a classic case of big boys and big toys!”).  It is a lot of fun to be able to walk through a large show of equipment and tooling that is all clean and painted – you can see what it is all supposed to look like!  As an engineer, you can learn a lot about the latest tools, equipment capabilities, and the like from the sales and manufacturing reps.  The ADSC always does a great job putting this event on, and this year’s venue a the J.W. Marriott Hill Country Resort outside San Antonio was fantastic.

Dan and Robert both had papers included in the proceedings. Links to the papers are below.  Erik and Tim had presentations along with those that Dan and Robert gave on their papers.  Links to the presentations are on our Presentations page.

Visit to Bond Bridge (kcICON Project) in KC

I was finally able to make my first visit to the Bond Bridge in Kansas City since it was completed.  It is a very beautiful bridge that fits well into the approach to Kansas City from the north.  As foundation engineers, we don’t always get a convenient opportunity visit the large bridge structures we work on since our work is usually completed very early in the overall schedule.  We are often too involved in other projects by the time a bridge is finished on which we were the foundation/geotechnical engineer.  So, it was a personal pleasure to make a visit and drive over the bridge when John Turner and I flew into Kansas City on our way to Topeka to present the NHI Drilled Shaft Course earlier this month.  Although it was a cloudy and cold day, I think the few photos I took with my phone (camera battery was dead!) turned out good.  Mouse over each for a caption.  Enjoy!

The new I-70 Mississippi River Bridge in St. Louis, Missouri is moving along and getting noticed in the news.  Here are a couple of (somewhat) recent articles:

The Republic (Columbus, Indiana) (01/29/2012)

St. Louis Business Journal (01/10/2012)

KMOX CBS (12/28/2011)

The New Mississippi River Bridge Project page maintained by MoDOT has links to all that is happening on the project.

You can get real-time updates of the construction from three web-cams at this link.  As I type today, the site is covered in snow.  Very beautiful, unless you are trying to build a bridge on time!

The project page also has photo galleries and other neat stuff.

stltoday.com has some albums with good photos, including this one.

Dr. Mike Holloway, P.E. comes aboard!

11_Mike_sDBA is pleased to announce that Dr. D. Michael Holloway, P.E. has joined the DBA team.  Mike is a recognized expert in driven pile foundation design and dynamic testing, in-situ testing, instrumentation, and earthquake engineering.  His over 40 years of foundation and geotechnical engineering experience includes stints at the U.S. Army Corps of Engineers Waterways Experiment Station (WES) in Vicksburg, MS, and Woodward-Clyde Consultants in Oakland, CA. He founded InSituTech, which specialized in engineering deep foundations and applying insitu soil testing services.

When starting InSituTech, Mike broadened the professional practice beyond “conventional” PDA-related testing and analyses services.  Rather than just test and report to satisfy QC requirements during construction, he applied dynamic testing and analyses to enhance foundation design and constructability, as well as to improve on-site troubleshooting of construction problems.   The efforts paid off as the firm made significant changes in the way PDA services became integrated into the design/build process on several major marine facilities and bridge projects in the west and in the Pacific.

Mike is a Blue Devil, having earned his B.S., M.S., and Ph.D. at Duke University in North Carolina.  Raised in New York, he made his way to California seeking engineering gold soon after his time at WES.  He has been based there ever since.

Mike’s presence in California makes DBA a practically coast-to-coast firm (well, at least East Tennessee to California).  We at DBA are excited at the expertise Mike adds to our portfolio and look forward to his contributions to the team.  Welcome, Mike!

Happy Karl Terzaghi’s Birthday 2011!

Greetings to all Terzaghi fans!  Yes, it is that time of year again, where our thoughts turn to the anniversary of the birth of one of the greats in our field.

Last year I had a football themed post (college football, in case you were wondering…and that is American football for our fans outside the U.S.) since Terzaghi’s birthday was on a Saturday. Since I am not a big pro football fan, and since I used football last year, I figured I would do something different for this year’s weekend post.

The August 2011 edition of the International Society for Soil Mechanics and Geotechnical Engineering ISSMGE Bulletin is headlined with an article on the history of ISSMGE: “THE ISSMGE FROM 1936 TO 2011 A RETROSPECTIVE ON THE OCCASION OF THE 75TH PLATINUM JUBILEE ANNIVERSARY” by Kenji Ishihara and Michele Jamiolkowski. The Bulletin is in two parts at this link. The article is an outstanding work providing an excellent account of the start of ISSMGE as an international conference and its evolution into the ISSMGE we know today.

It should be no surprise that Prof. Terzaghi was very active and one of the key figures in the formation and success of ISSMGE, which began as the International Conference on Soil Mechanics and Foundation Engineering (ICSMFE). Many of the giants of soil mechanics and geotechnical engineering on which we base al of our work were instrumental in the start of ICSMFE and its impacts on our profession. As for that time in history (1936) and how it was important to our field:

The time had come to hold a Conference aimed at exchanging and sharing information on Earth and Foundation Engineering.

It was Professor Arthur Casagrande (assistant professor of Harvard University) who sensed the timing, conceived the idea and carried out the herculean task of running the conference all the way through, in his role of Secretary General, with K. Terzaghi (Professor of Technical University of Vienna and visiting Professor of Harvard University) as Chairman. Professor Peck once remarked “Our Society owes an enormous debt to Arthur Casagrande for his conviction that the time was right for the International Conference and to his tremendous efforts to organize it“.

…

Since the first ICMSFE was so successful, it became clear that the Conference should not remain a one-off event but should, instead, be continued within a few years, possibly being held in Holland where earthwork engineering is so crucial to the country.

It was also requested to set up a permanent international organization. Thus it was decided to establish International Committees consisting of National Committees with K. Terzaghi as President and A. Casagrande as Secretary. It was also decided that at the next Conference the International Committees would submit the draft of the Constitution and of the By-laws, which are essential for the Society to become a permanent organization.

There was at that time a widespread awareness that it was the moment to set up a common denominator institution that would group engineers with diverse backgrounds but involved in our discipline.

And the rest, as the saying goes, is history!

As an editorial note on the first year, Ishihara and Jamiolkowski offer this observation:

It is commonly recognized that K. Terzaghi is the originator of modern soil mechanics and foundation engineering and therefore father of our profession. After tracing the history of development, the writers had a strong belief that this is true. Not only was he always a leading figure in the forefront, but he conveyed strong messages on the role and importance of the soil mechanics and foundation engineering every time he participated in the ICSMFE. We are very much impressed by his enthusiastic and heartfelt message to our community.

No less important was the role played by Arthur Casagrande. He was instrumental in persuading the President of Harvard University to host the conference and carrying out all arrangements for organizing the first International Conference on Soil Mechanics and Foundation Engineering. The great success of this conference contributed greatly for establishing the place of soil mechanics in engineering practice throughout the world. He also dedicated himself to the ISSMFE as the 3rd President between the periods of 1961 in Montreal to 1965 in Paris.

There is a saying that for a great religion to be established, there always are two key-role playing giants. For Christianity Jesus Christ is the originator and his disciple Saint Paul was the great evangelist. For Greek philosophy, Socrates was the great philosopher and it was Plato who was the greatest disciple. Terzaghi and Casagrande are considered as a combination in the same context. Without Terzaghi, Casagrande would not have been so well-known. Had there not been Casagrande, the fame of Terzaghi would have developed in a different format.

Now neither I nor the authors are suggesting that soil mechanics is a religion, but their point on the timing and combination of Terzaghi’s and Casagrande’s work was critical to what we see as the field of soil mechanics/geotechnical engineering today. Without these two and others seeing a need, taking charge, and filling that need, we could very well be viewing things from a completely different framework.

So as we reflect on this celebrated day, let’s remember not only Prof. Terzaghi’s great technical achievements, but also his role as a leader (along with many others) shaping our field of practice and our professional societies.

Now Published! 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 a National Cooperative Highway Research Program synthesis report by Dan and Robert: 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.

Included in the report are:

  • Responses from a survey sent to all 50 state departments of transportation plus the District of Columbia and Puerto Rico (44 of the 52 agencies provided responses).
  • Interviews performed by telephone or in-person of nine of the responding agencies selected based on the written survey responses.
  • A comprehensive literature review on the range of practices included in test pile programs and their use in developing production pile driving criteria.
  • Discussions of the survey results.
  • Useful practices identified from the surveys.
  • Identification of research needs for this topic.
