DBA has had the privilege to be the geotechnical/foundation engineer for the , a design-build project for the The project will replace the existing Goethals Bridge that was built in the 1920s and carries I-278 over the Arthur Kill River between Elizabeth, New Jersey and Staten Island, New York.
Welcome to the Department of Civil Engineering.
The Department focuses on advanced research and education in the broad areas of Geotechnical, Structural, Transportation, and Water Resources & Environmental Engineering. The Department is in the Division of Mechanical Sciences at the Indian Institute of Science (IISc), Bangalore.
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 (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 , 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 be conforming to the (mostly) standard DBA hair style. Ali will work in our Knoxville, Tennessee office.
The areas of study in the ocean engineering include fluid mechanics, structural mechanics, ocean wave mechanics, oceanography, geotechnical engineering, coastal engineering, environmental fluid mechanics, marine structures, naval architecture, diving and moored systems, underwater acoustics, laboratory measurements, and ocean engineering design.
Ben recently completed his Ph.D. in geotechnical earthquake engineering at 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:
These showed the practical application of the system and how this effectively supports geotechnical engineers in embedding sustainability into projects.
The new version, called ‘GeoSPeAR’ in this thesis, allows for greater communication between masterplanning and geotechnical engineering via their common base, thus avoiding a potential barrier to greater adoption of more sustainable practices through the construction cycle.
in civil engineering at , I have continued my studies in civil engineering-geotechnics at as well.
I am currently working as a Consulting Engineer on the field of Geotechnical & Industrial structures Design, concentrating on Tunnel design and Blast resistant structures design.
My Bachelor's studies were mainly about civil engineering and my research was focused on soil engineering.
Foundation construction will start in late November or early December with the installation of 30-inch diameter micropile foundations for the western pier of the three span, steel plate girder bridge. Although the foundation work is just about to get started, DBA has been hard at work on the project for over a year. DBA first got involved as a consultant to for the design-phase load test program conducted last fall. Since then, DBA was contracted as the geotechnical engineer of record for the project. Working with bridge designer , DBA designed the bridge foundations, an anchored abutment, and rockfall hazard mitigation systems for this geologically challenging site. DBA has also analyzed several soil and rock slopes to verify stability of the bridge and roadway.
DBA is currently working with structural designer to design what will be Minnesota’s tallest bridge. The bridge will span the currently inactive Rouchleau open pit iron ore mine near Virginia, Minnesota. MnDOT is moving the alignment of the existing Hwy 53 to make way for future mining in the area. DBA is the lead geotechnical designer on the project in addition to being contracted as MnDOT’s load test expert for the ongoing design phase load test program.
Following detailed discussion with a variety of practitioners, the methodology was significantly adapted to make it applicable to geotechnical problems and ensure that geotechnical engineers can understand and use it with relatively ease.
