Geotechnical Engineering

CTE ensures a maximum utilization of site potential. Coordinated geotechnical and geological service teams conduct comprehensive site investigations to evaluate subsurface soil, rock, and groundwater conditions. Geotechnical investigations include the analysis and recommendations for site grading, excavation, slope stability, shoring, foundation design, design of necessary above and below grade walls, and site pavements.

Our fundamental objective is cost-effective recommendations associated with design practicality and rapid information turnaround for our clients. Geotechnical studies further support civil engineering design recommendations for conclusive land-use planning including road design, asphalt, concrete and pervious paving requirements, and safe site drainage.

Recognized as a leader in efficient geotechnical engineering, CTE continues a history of developing effective designs for conventional and complex site requirements. Through strategic planning, we develop necessary site solutions to minimize geologic or seismic impacts on the design. Detailed reporting formats provide the planning criteria necessary to mitigate existing site constraints through practical, efficient, and appropriate geotechnical engineering design.

Geophysical Surveys

CTE, with the support of UES' nationwide resources and personnel, leverages geophysical science as a cost-effective, non-intrusive means to rapidly characterize subsurface conditions and man-made structures. Our experience spans from engineering investigations involving pre-design and pre-build geologic characterizations to forensic assessments of distressed property and “cause of subsidence” evaluations.

Our Geophysical Surveys optimize drilling and sampling programs and measure bulk physical properties complementary to conventional engineering sampling methods. These surveys are a cost-effective means to map underground utilities in the design phase or prior to start of new and remedial construction activities. CTE’s geophysicists, geologists, and engineers can provide clients with optimal solutions to the most challenging of engineering problems. In addition to direct push and conventional drilling, CTE also offers Crosshole Sonic Logging and Sonic Drilling services with UES' support.

Advanced Development Activities

The development of new sites often requires several studies to ensure that the site is compatible with its intended use. These studies include characterizing soil and groundwater conditions, evaluating the potential for sinkhole activity on the site, and location of muck on the site that could adversely affect performance and construction costs of structure and pavement areas. Soil testing is performed in-house in our geotechnical soils testing laboratory facilities which have been certified by AASHTO (American Association of State Highway Transportation Officials).

Some of our Advanced Development Activities services include:

  • Site Feasibility Studies
  • Site Grading Specifications
  • Geotechnical Earthquake Engineering and Seismic Hazard Evaluations
  • Selection of Seismic Design Parameters
  • Soil Mapping and Classification
  • Settlement/Heave Analysis and Monitoring
