Design and construction of functional transportation structures requires an in-depth understanding of the interaction of soil, rock, and groundwater conditions. Precertified in the practices and standards required by the Texas Department of Transportation (TxDOT), Raba-Kistner has partnered for almost four decades with TxDOT on a wide variety of geotechnical engineering studies.

Systematically collecting and analyzing basic to complex geotechnical data, Raba-Kistner has participated in all phases of TxDOT project success. In South Texas alone, we have contributed to over 10,000 public and private sector geotechnical studies. In conjunction with most studies, we have carried field and laboratory testing programs for bridge foundations, retaining walls, roadways/highways, and signage/light standards. Field procedures, boring spacing and depth requirements as established by TxDOT’s Geotechnical Manual, October 2000 are rigorously followed.

Whether working with Texas Turnpike Authority, regional mobility authority, regional toll authority, or through private-sector developers, Raba-Kistner is capable of fulfilling the requirements of accelerated delivery. We participate in exclusive development agreements (EDA), and comprehensive development agreements (CDA) as an alternative means of supporting needed road and bridge construction. Engineering safe, efficient, and cost-effective transportation solutions continues to be our priority.
