The South Carolina Department of Transportation (SCDOT) Geotechnical Design Manual (GDM) has been developed to provide uniform design practices for Department and consultant personnel preparing geotechnical reports and contract plans for SCDOT projects. The designer should attempt to meet all criteria and practices presented in the GDM, while fulfilling SCDOT’s operational and safety requirements. This Manual should be used in conjunction with the Bridge Design Manual and the Seismic Design Specifications for Highway Bridges.
The GDM presents most of the information normally required in the geotechnical design of transportation projects; however, it is impossible to address every situation that the designer will encounter. Therefore, designers must exercise good judgment on individual projects and, frequently, they must be innovative in their approach to geotechnical design. This may require, for example, additional research into geotechnical literature.
The August 2008, Version 1.0, and the June 2010 Chapters 13 through 26 and Appendices B through G join together to form the complete SCDOT Geotechnical Design Manual, Version 1.1. Appendix E contains a list of Geotechnical Template Plans that may be obtained at Drawings and Details. Any questions concerning the applicability of procedure, analysis, or method should be directed to the Preconstruction Support – Geotechnical Design Section (PCS/GDS).
Updates
As the need arises, Bridge Design Memorandums will be issued to supplement or revise the requirements of the GDM.
