Department of Transportation and DevelopmentLouisiana State University (Baton Rouge, La.)Rupnow, Tyson D.Gautreau, Gavin P.US Transportation CollectionThe Louisiana Department of Transportation and Development (DOTD), through its Pavementand Geotechnical Design section, has developed policies and procedures over the years utilizing its own methods and those incorporated from others (AASHTO, FHWA, other states, etc.). The Geotechnical Design group has a formal Geotechnical Engineering Design Guide (GEDG) No. 8, Mechanically Stabilized Earth Wall (MSEW), but does not have guides that document other issues (i.e., subsurface exploration, piles, drilled shafts, slopes, etc.). A comprehensive Geotechnical Design Manual (GDM) will assist the Geotechnical Design group by formally establishing policy and providing guidance in production activities. The manual willalso help clarify current design policy, ease the training of new employees, and serve as a valuable reference for the Geotechnical Design group, other DOTD sections, and consultants.Implementation of a GDM will establish procedures for handling comments and/orrecommendations regarding potential revisions so they can be effectively addressed. Benefits of a GDM include efficiency and clarity of having the policy online as well as creating confidence and transparency for all actions and design decisions
