Robert Bachus, Ph.D., P.E., is a principal engineer based in Georgia with more than 25 years of professional experience. His practice focuses on geotechnical engineering, geoenvironmental engineering, waste by-product characterization, and the permitting and design of waste containment facilities. He provides analysis, design, and forensic investigation services on projects related to these practice areas. He also provides expert consultation on matters in litigation.
Robert is nationally recognized for his expertise in geotechnical site characterization, in situ and laboratory testing, settlement and slope stability analysis, and performance monitoring of geotechnical and earthen structure systems. He has consulted extensively on the design and rehabilitation of earth dams, levee structures, and earth retaining systems, and has extensive experience with soil and rock strength characterization and slope stability assessment. Robert recently applied his expertise to resolve construction difficulties related to a 250-foot-high gold mine tailings dam and design issues associated with permanent access roads on levees and dredged material containment dikes. He is a leading authority in the characterization, assessment, and construction of engineered structures in areas underlain by karst geologic features.
Robert is among the nation's top researchers who study the beneficial re-use of coal combustion by-product materials and explore engineering applications for geosynthetic materials. He continues to examine these topics and recently served as the lead author of a design guidance document related to drainage geocomposites used in civil engineering applications.
Robert was co-chair of GeoCongress 2006, a national conference sponsored by the American Society of Civil Engineer's Geo-Institute that emphasized “geotechnical engineering in the information age.” His applied research in geotechnical engineering and solid waste management has yielded significant advancements in performance monitoring instrumentation used for assessing settlement beneath embankments and other earthen structures.
In addition to his ongoing research, Robert is the author or co-author of more than 100 technical publications, including guidance documents produced on behalf of the Federal Highway Administration regarding geotechnical engineering design and technical research and reports on the geotechnical properties of fly ash for the Electric Power Research Institute.
