The Evolution of Geotechnical Engineering in Texas

Presented By: Dexter Bacon, P.E., with Intertek-PSI.


The presentation will include a discussion of the following items:

  • A continual evolution in geotechnical recommendations over the last 35 years.
  • The changes are a result of trial and error observations, more sophisticated analysis techniques and innovative new technologies.
  • Structure damage from expansive soils still a problem.
  • Costs associated with building structures that have little to no cracks from foundation movement.
  • Examples of what was typically done in the 80s and 90s compared to what is done now and insights into why the changes occurred.
  • No 4th order differential equations. Just lots of pictures and observations and a few aha moments.

The presenters would also like to encourage the audience to come with questions - anything they may have seen in their experience that have led to foundation concerns. Or if they have had questions or concerns with past geotechnical recommendations. The presenters would like to have the question and answer period not only address the items in the presentation but also address any other questions they may have from practice.


Mr. Dexter Bacon was born in Jesup, Georgia in 1957 and lived in Georgia and North Carolina growing up.

He attended the Georgia Institute of Technology where he graduated in 1978. He married his high school sweetheart, Diane, that same year.

After working for a year with a small geotechnical consulting firm in Atlanta, Dexter and Diane moved to Corpus Christi in 1979 where he was hired by Professional Service Industries (PSI) as the Geotechnical Manager of the local PSI office.

In Corpus Christi in the 80’s, Dexter worked for PSI, Maverick Engineering Company, his own firm, Soil and Foundation Engineers, and the Port of Corpus Christi.

He also attended Texas A&I University between 1983 to 1986.

From 1991 to 1997, Dexter was District Manager and Senior Geotechnical Engineer for PSI in Corpus Christi over the Corpus Christi, Victoria and Harlingen areas.

In 2000, Dexter, Diane and their son Brian moved to San Antonio. Dexter accepted a positon with a San Antonio geotechnical and testing consulting firm, Arias & Associates where he worked until 2013. At that time, Dexter took on his current position as Chief Engineer with PSI and oversees the technical aspects of geotechnical projects for PSI in the Central and South Texas areas.

Dexter has always had a passion for geotechnical engineering and the talk today centers around the evolution of geotechnical engineering in this area.
