Geotechnical Design Manual (2022)

The Geotechnical Design Manual (GDM) provides uniform design practices for designers preparing geotechnical reports and contract plans for SCDOT projects.

Any questions concerning the applicability of procedure, analysis, or method should be directed to the Office of Engineering Support - Geotechnical Design Section (OES/GDS).
