Dan has taken on some new responsibilities with the Deep Foundations Institute (DFI). He has joined both the Board of Directors and the Educational Trust Board as treasurer. From DFI:
Dr. Dan Brown has joined the DFI Educational Trust Board and the DFI Board of Trustees as treasurer, effective January 1, 2014. Dr. Brown is recognized as one of America’s leading authorities on the construction and design of deep foundations for transportation structures. After 22 years on the faculty at Auburn University, Dr. Brown remains active in deep foundation practice through his consulting firm, Dan Brown and Associates. He has been recognized with the DFI Distinguished Service Award, ASCE Martin Kapp Foundation Engineering Award and the ADSC Outstanding Service Award.
David Coleman of Underpinning & Foundation Skanska, has been elected to a second five-year term as Trustee (2014-2019), and Roger Healey of Goettle, was elected to second two-year term as At-Large Trustee (2014-2016).
The elected officers for the Board of Trustees in 2014 are:
Here is a blast from the past on pile groups: NCHRP Report 461 – Static and Dynamic Lateral Loading of Pile Groups. I had a request for this report recently, so I found it and figured we needed to post the links to it. Dan was the lead researcher on this report during his time at Auburn University, and had an all-star line up that included Dr. Mike O’Neill and Dr. Mike McVay, two of the heavy hitters in foundation engineering. The report introduction gives a good summary of the contents:
A key concern of bridge engineers is the design and performance of pile group foundations under lateral loading events,
such as ship or ice impacts and earthquakes. This report documents a research program in which the following were developed:
(1) a numerical model to simulate static and dynamic lateral loading of pile groups, including structural and soil hysteresis and energy dissipation through radiation; (2) an analytical soil model for nonlinear unit soil response against piles (i.e., p-y curves) for dynamic loading and simple factors (i.e., p-multipliers) to permit their use in modeling groups of piles; (3) experimental data obtained through static and dynamic testing of large-scale pile groups in various soil profiles; and (4) preliminary recommendations for expressions for p-y curves, damping factors, and p-multipliers for analysis of laterally loaded pile groups for design purposes. The report also describes experimental equipment for performing site-specific, static, and dynamic lateral load tests on pile groups.
Several full-scale field tests were conducted on pile groups of 6 to 12 piles, both bored and driven, in relatively soft cohesive and cohesionless soils. All of the groups were loaded laterally statically to relatively large deflections, and groups of instrumented pipe piles were also loaded dynamically to large deflections, equivalent to deflections that might be suffered in major ship impact and seismic events. Dynamic loading was provided by a series of impulses of increasing magnitude using a horizontally mounted Statnamic device.
For a relatively short (50 pages) report, there is a lot of information packed into it gleaned from a lot of full-scale field work.
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/DFIDrilled 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.
Later in the month, Dan and Robert Thompson are both featured at the 2012 Midwest Geotechnical Conference hosted by Ohio DOT in Columbus, Ohio. Dan will be speaking on base grouted shafts while Robert will give his presentation on the ADSC SE Chapter rock socket load test research program.
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.
Dan has been selected by the DFI Educational Trust to deliver the 4th Annual Osterberg Memorial Lecture. The lecture is given at a benefit dinner for the DFI Educational Trust Scholarship Funds. The dinner this year will be held in conjunction with the joint DFI-ADSC Seminar Drilled Shafts: Top to Bottom on September 12th in Denver. From DFI:
The Osterberg Memorial Lecture has been established in honor of Dr. Jorj Osterberg, inventor of the Osterberg Cell, to recognize innovations in the deep foundations construction industry and related to deep foundations engineering design, testing or education; all aspects of his lifelong contributions.
According to the invitation letter from DFI, the committee selects a “person who encompasses the spirit of the lecture which is to emphasize innovations or contributions to the deep foundation industry and related to deep foundation engineering design, testing or education, all aspects of Jorj Osterberg’s lifelong contributions.”
Today DFI Educational Trust is an independent charitable foundation of the Deep Foundations Institute. The TRUST manages the Annual Student Paper Competition, the Annual Young Professors Paper Competition, the History of Deep Foundations Poster Program, the Sustaining Membership Fund and the Paul DeBruyn Memorial Student Scholarship Fund, the Berkel & Company Contractors Inc. Scholarship Fund, and the Annual Osterberg Memorial Lecture. These programs, along with future initiatives, will play a large role in enabling better Industry-Academia communications by instilling an interest in the heavy construction and civil engineering sciences in both high school and college level students.
Currently the TRUST plans to awards annually four Student Scholarships in the amount of $12,500 each to undergraduates studying in the field of civil, geotechnical or construction engineering. Auburn University, Carnegie Mellon, University of California-Berkeley and University of Illinois are awarded the funds and select students based on the TRUST’s criteria of majoring in one of the above fields of engineering with interest in deep foundations construction and having financial need. Additionally the TRUST provides scholarships to high school students in partnership with the ACE Mentor Program for those interested in pursuing college studies in engineering or construction management. These scholarships are endowed through charitable donations and fund raising events, such as golf outings and benefit dinners.
Creating opportunities for students to see Industry in action is another large element of the DFI Trust mission, by providing affordable student attendance of DFI Conferences and technical seminars, site visits and live demonstrations or by bringing Industry Experts into the classrooms. The TRUST is proud to announce the formation of its first student chapter at UC-Berkeley in 2009.
The drilled shaft foundations for the new I-70 Mississippi River Bridge in St. Louis, MO are the subject of two recent papers written by Paul and Dan and published by DFI. Dan presented the paper focusing on the Alternate Technical Concept (ATC) process at the DFI 36th Annual Conference in October. (previous post here). A case history paper by Paul and Dan was published last month in Volume 5, Number 2 of the DFI Journal. Links to the papers are below, as well as on our Publications page. Other posts on this bridge are here.

The Deep Foundations Institute is pleased to announce Dan Brown, P.E., Ph.D., as the recipient of the DFI 2011 Distinguished Service Award. The award, in its 31st year, honors individuals chosen by their peers for exceptional contributions to DFI and to the industry.
Brown began his career with a B.S. from Georgia Tech, and later received his Ph.D. at the University of Texas, Austin, in only 28 months, while working. He then taught at Auburn University for 22 years before setting up his own consulting firm in Tennessee. The Winter 2011 issue of the DFI magazine included a profile of Brown that chronicled the universal admiration and regard for him within the industry. He was cited by others for his expertise, his intelligence and ability to teach others. Brown and his firm are sought out for advice everywhere.
