Transportation and Design-Build Expertise
Geotechnical analysis and design for the most demanding transportation infrastructure.

Our experienced design-build team is ready to take on your transportation project, no matter how large. As the team responsible for all aspects of geotechnical characterization, analysis and design, we have a broad array of expertise with various infrastructure components. We often act as the Geotechnical Design Manager on design-build projects, and work closely with design teams on site.

State Department of Transportation Experience

GeoEngineers has a long history of working with state departments of transportation (DOTs), and provides on-call services to DOTs in Louisiana, Washington, Oregon, Idaho and Missouri. Our breadth of company expertise and strong familiarity with geotechnical and environmental DOT policies, AASHTO specifications and FHWA guidelines for state transportation projects means industry-leading work, which has received both state and federal recognition. Our in-house staff experience and long history of DOT work in multiple states position us to take on any design-build project:

  • Geoengineers has worked with the Louisiana Department of Transportation and Development (LA DOTD) for decades, often on retainer contracts. Two of our principals have direct experience working for LA DOTD earlier in their careers.
  • Approximately 400 projects completed for the Washington State Department of Transportation (WSDOT), from testing services to multi-million dollar design-build highway projects.
  • Close ongoing relationship with Missouri Department of Transportation (MoDOT), who has relied on us for geotechnical problem-solving. Our team includes the former MoDOT Geotechnical Director, who boasts more than 29 years of state DOT experience before joining GeoEngineers.

Specialized Testing

GeoEngineers staff have decades of experience testing driven pile foundations using the pile driving analyzer (PDA, a non-destructive method or NDT). We have PDA and Crosshole Sonic Logging (CSL) equipment in-house to meet large transportation project needs. GeoEngineers also has experience in providing specialized geotechnical field testing such as inclinometer slope monitoring, settlement monitoring, and soil pore pressure monitoring.


GeoEngineers has been involved in several large design-build procurements, including the Port Mann Bridge and South Fraser Perimeter Road projects in Vancouver, the I-15 Core project in Utah and the SR-520 Floating Bridge in Seattle. We have mastered the art of successful integration into a contractor’s team while managing the owner’s expectations. We are experienced in assisting design-build teams to prepare competitive costs, approaches and proposal submittals.

Reliable Partners

Our nation-wide project portfolio across 14 offices means we know how to work with a variety of partners within any context. We have worked on both design-build and large-scale, conventional, geotechnical design projects throughout the U.S. and Canada, often contributing our expertise to local partner firms.
