DBA is growing again – welcome to Ali, Ben, and Mark!

Well, we are at it again.  The first 5 months of 2016 have seen us add three new faces of the new website creator.  So now, drum roll, please………

Ali Leib, E.I.

Ali 2016-1

Ali was a summer intern at DBA in 2014 and 2015 and joined us full time as a staff engineer in February.  She is a recent graduate of the University of Tennessee (Go Vols!) where she completed both her B.S. and M.S. in civil engineering. While completing her M.S., she was a teaching assistant in charge of grading lab reports for the structural and geotechnical undergraduate labs. She was also a research assistant under Dr. Dayakar Penumadu, resulting in her thesis: “Effect of Particle Morphology on the Deformation Behavior of Sand under Monotonic Loading Conditions.”  Unlike most of the rest of us, Ali insists that she will not be conforming to the (mostly) standard DBA hair style.  Ali will work in our Knoxville, Tennessee office.

Mark Madgett, P.E.

Mark Madgett_s

 

Mark received a BS and MS degree in Civil Engineering at the University of Tennessee, while working on research for TDOT to improve pavement design methods.  He has worked in both consulting and construction for the last 22 years, focusing primarily on deep foundations in the Southeastern US.  As a consultant, Mark gained extensive field experience with deep foundation construction techniques and the impacts on design.  In 2006, he began working for Seaboard Foundations, opening a green field office in Tri-Cities TN as the district manager.  In his role as design engineer for Seaboard Foundations, Mark has implemented design-build techniques in many markets (energy, institutional, commercial, transportation, and healthcare) that vastly improved the constructability and reduced the costs of deep foundation systems for his clients.  Mark will also work outr of our Knoxville, Tennessee office.

Ben Turner, Ph. D., P.E.

Ben recently completed his Ph.D. in geotechnical earthquake engineering at UCLA with an emphasis on the transfer of forces between the ground and foundation elements during seismic loading. Prior to starting at UCLA, he worked for two years for the Los Angeles office of Shannon & Wilson, Inc.  Ben worked in both construction and geotechnical firms while attending school for his B.S. and M.S. degrees. His experience includes: design, construction, and load testing of deep foundations;  geotechnical earthquake engineering including soil-structure interaction, seismic hazard analysis, site response, liquefaction triggering analysis and mitigation of liquefaction-induced ground failure; and, characterization of structural behavior of reinforced concrete foundations.  Here are two of the publications resulting from his dissertation work:

Turner, B., Brandenberg, S., and Stewart, J. (). “Case Study of Parallel Bridges Affected by Liquefaction and Lateral Spreading.” J. Geotech. Geoenviron. Eng. , 10.1061/(ASCE)GT.1943-5606.0001480 , 05016001.

Turner, B. and Brandenberg, S. (2015) “Pile Pinning and Interaction of Adjacent Foundations During Lateral Spreading”, DFI Journal, Volume 9, Issue 2.

Ben will anchor the West Coast Region of DBA, working from San Luis Obispo , California.

 

Kansas City Load Test Photos Added

BPU Load Test

Last spring, DBA conducted a construction phase load test program for a U.S. Army Corps of Engineers floodwall improvement project  along the Missouri River in Kansas City, Kansas.  Located on property owned and maintained by the Kansas City Board of Public Utilities (BPU), the BPU floodwall was slated for structural improvements including a series of buttresses founded on 24-in drilled shafts.  As part of the project contract a load test program performed under the direction of a qualified P.E. and D.GE was required.  General contractor L.G. Barcus & Sons, Inc., secured our Paul Axtell, P.E., D.GE as the qualified load test expert.  DBA teamed up with load testing subcontractor Applied Foundation Testing, Inc., to perform the static load tests.

The load test program requirements included three test shafts, a statically loaded axial test shaft, a statically loaded lateral test shaft, and a combined statically loaded axial and lateral test shaft.  The required combined lateral and axial test shaft provided some unique challenges with respect to applying the loads and collecting data.  As can be seen in the picture above, the axial load was applied using dead weights.

We have added selected pictures from this unique project to our web albums, which can be viewed here.

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.

Dan Inducted into the UT Austin Cockrell School Academy of Distinguished Alumni

Barry Meyer, P.E. joins DBA!

12_Barry MeyerWe are pleased to announce that Barry J. Meyer, P.E., has joined DBA. Barry is a recognized expert in the design and construction of deep foundations. His over 30 years of geotechnical engineering experience includes time at McClelland Engineers in Houston where he designed large diameter high capacity driven piles for major offshore structures and developed subsea geotechnical instrumentation. He applied that knowledge at Marathon Oil Company where he was part of the team that installed the Steelhead oil production platform in Cook Inlet, Alaska.

After his time in Texas, Barry spent time at both Leighton and Associates and at Law Engineering in California, before joining HDR in their Tampa, Florida office. During this time, his drilled shaft experience includes the H-3 Windward Viaduct on Oahu, Hawaii where drilled shafts were used for the first time to support a major bridge structure and are now the foundation of choice in Hawaii. He was also innovative in the use of the Osterberg O-Cell as part of the repair of the Los Angeles Coliseum after the devastating Northridge earthquake.

Barry has worked on numerous international projects in a variety of capacities including the Confederate Bridge connecting New Brunswick to Prince Edward Island over the ice filled Northumberland Straits; the 55 km elevated Bang Na Expressway Project in Bangkok, Thailand; and the Puente de la Unidad cable-stayed bridge over the Santa Catarina River, Monterey, Mexico. He also has considerable seismic engineering experience, and has designed and constructed flood protection levee systems and water storage reservoirs.

Barry will be based in the Tampa, Florida area. You can check out more details about him on the About Us page of our blog.  Welcome, Barry!

Welcome to DBA, Nathan Glinski!

12_Nathan_s

DBA is proud to announce the addition of Nathan Glinski, E.I. to our staff.  Nathan is a recent graduate of the Georgia Institute of Technology (like Dan and Tim! Go Jackets!). Nathan completed his M.S. in civil engineering at Georgia Tech where he also did his undergraduate work. While at Georgia Tech, Nathan was a research assistant under the supervision of Dr. David Frost, P.E. where he investigated the use of pile foundations as geothermal heat exchangers. In addition to his research, Nathan was a teaching assistant for an undergraduate geotechnical engineering course, gaining experience in a wide variety of laboratory soil tests as well as managing the grading of reports and homework for 100 undergraduate students. Nathan has been the resident summer intern for DBA since 2010 and will now be joining us full time as a staff project engineer.

On a more personal note, Nathan is also an accomplished trials motorcycle rider, having been riding since a youth.  He has often ridden the courses and trails at the Trials Training Center (owned by Dan and co-located at DBA World HQ).  He is a big volunteer/instructor/participant in events at the TTC, as seen in two posts last year here (helmet cam while riding a course), and here (instructor).

As you can see from his photo, he has adopted the official hairstyle of DBA.  Coincidentally, being comfortable in a hard hat also means comfort when wearing your trials helmet!

Mike Holloway in DFI Magazine

The July/August 2012 issue of Deep Foundations features one of our newest employees, Dr. Michael Holloway, in its “People, Projects and Equipment” section.  The article, entitled “D. Michael Holloway: Strong Mind, Strong Personality,” follows Mike’s education and career as a geotechnical engineer from his “outrageous streak” in high school to his current position at DBA.  If you are interested in learning more about the “strong mind” and “strong personality” that is Mike Holloway, click the link above or check your mailbox for a copy of the latest copy of Deep Foundations, only from DFI.

This is not the first time we have been lucky enough to have one of our own featured in the “People, Projects and Equipment” section.  Some of you may remember that Dan was featured in the Winter 2011 issue.  A copy of that article and the associated blog post can be found here.
