Geotechnical Engineering and Consulting

Twenty years of experience in the geotechnical industry has developed a strongly qualified and experienced team that provides a broad range of geotechnical services.  With the spectrum of geologic conditions present in the St. Louis Metropolitan area, each project site poses unique challenges.  A geotechnical study helps identify these challenges and allows the implementation of a design or solution before the construction phase of the project.  EOI develops complete and detailed geotechnical reports that accurately characterize subsurface conditions, engineering properties, geotechnical concerns, and cost-effective solutions.

EOI knows that the implementation of geotechnical recommendations can impact a project budget, schedule, and productivity.  When feasible we implement Value Engineering based on a thorough analysis of the site conditions, the owner’s tolerance of risk, and cost-effective and practical solutions to the geotechnical problem.
