GEOTECHNICAL ENGINEERING
Geotechnical engineering is foundational to project performance. GEOCON delivers subsurface characterization and engineering analysis to support safe, efficient, and constructible design solutions.
GEOCON Projects
Communications Tower Projects – Geotechnical Evaluations
Enbridge Energy Flanagan Terminal – Geotechnical Engineering
The Pickus Companies – Geotechnical Evaluation
University of Illinois – Geotechnical and Construction Inspection
University of Illinois – Geotechnical Evaluation
University of Illinois Residence Hall – Geotechnical Evaluation


Our investigations are designed to identify variability in subsurface conditions and quantify engineering parameters that influence foundation systems, pavements, and earthwork. Through early-stage evaluation, we reduce project uncertainty and mitigate risks associated with unsuitable soils, groundwater conditions, and undocumented fill.
GEOCON’s vertically integrated model—combining in-house drilling, sampling, and laboratory testing—ensures data consistency, accelerated turnaround times, and direct coordination between field and engineering staff.
GEOCON is prequalified with the Illinois Department of Transportation (IDOT) and the Indiana Department of Transportation (INDOT) for a comprehensive range of geotechnical services.

Our IDOT prequalifications include:
-
Geotechnical Services – General Geotechnical Services·
-
Geotechnical Services – Structure Geotechnical Reports (SGR)·
-
Geotechnical Services – Subsurface Explorations
-
Special Services
In addition, GEOCON is prequalified with INDOT under:
7.1 Geotechnical Engineering Services
These prequalifications demonstrate our capability to perform subsurface investigations, engineering analyses, and technical reporting in accordance with state DOT requirements and federally funded project standards. Our team is experienced in delivering geotechnical data packages, foundation recommendations, and structure-specific analyses that meet DOT review and approval processes.
Let us explain how you can leverage our expertise to assure your project’s success.
