About Design Resources:
The Office of Geotechnical Engineering Design Resources are divided into two Sections: the Foundations and Walls Section, and the Roadway and Geohazards Section.

The Foundations and Walls Section is led by Assistant Office Administrator Jawdat Siddiqi. The Section is responsible for oversight of AASHTO LRFD design of structures foundations, foundations related items in the ODOT Bridge Design Manual, and Geotechnical involvement in specifications committees. Jawdat Siddiqi is the current chair of the AASHTO T-15 Subcommittee on Bridges and Structures. This section is involved in retaining wall system approval, retaining wall inventory, and maintaining the Geotechnical design checklists, and coordinating Geotechnical design aspects with the Project Development Process (PDP).

The Roadway and Geohazards Section is led by Assistant Office Administrator Stephen Taliaferro. The Section is active in cataloguing Geohazards and other Geologic and Geotechnical features, employing Global Positioning, Geodetics, and GIS.  The Section is involved in the development of geohazard inventories and risk assessment processes, including the development of the Abandoned Underground Mine and Risk Assessment Manual and provides support to the Districts for its implementation.  They also assist in implementation of ODOT Geotechnical and Geohazard policy for remediation of Landslides and Rockfalls. The section also maintains an archive of historic Geotechnical data as a valuable resource in the planning of current projects.

Both Sections are responsible for oversight of the roadway geotechnical aspects of ODOT projects. We review geotechnical deliverables (reports, soil profiles, calculations, etc.) and roadway plans for geotechnical content. We also perform in-house geotechnical explorations and designs for roadway projects and geohazard remediations. In construction, the we make ourselves available to support projects that have extraordinary geotechnical features.

In addition to project work, we develop and maintain specifications for the performance of subsurface explorations. We also review and develop plan notes, proposal notes, and special provisions related to earthwork and geotechnical engineering. We also author Geotechnical Bulletins to provide guidance for various aspects of Geotechnical design, analysis, and instrumentation.
