D. Scott Kieffer
background
Prior to joining the Colorado School of Mines in the summer of 2002, I acquired over ten years of industry experience that commenced in the field of engineering geology and progressed to the traditionally separate fields of geotechnical engineering and heavy civil design. As an engineering geologist my work focused on geologic site characterization, paleoseismic investigations, and geologic hazards assessments. As a geotechnical engineer, I have provided consultation for the siting, construction and rehabilitation of large dams and hydropower facilities in Europe, Central America and the U.S., and have designed stabilization schemes for both natural and excavated rock slopes. Most recently as an Associate Design Engineer with Jacobs Associates, my work involved detailed geotechnical analysis and heavy civil design for major underground transit and water resources projects in Australia, Asia, and throughout the U.S. Detailed designs have included soil nails, high-capacity tie backs, soldier piles, rock bolts and dowels, steel ribs, spiling, final shotcrete and steel linings, and heavy pipe umbrellas. Design methods have ranged from empirical approaches and rock mass classification systems, to sophisticated numerical modeling of sequential tunnel excavation and support. From holding positions of responsible charge as a Professional Engineer (P.E.), Certified Engineering Geologist (C.E.G.) and Registered Geologist (R.G.), the synergistic combination of geotechnical engineering, structural analysis and engineering geology has become clear. Without a strong grounding in mechanics, the geologist cannot realize the engineering implications of observations made, as an engineer without a working knowledge of geology cannot appreciate the inherent fuzziness of geologic data and the potential impacts of geologic processes on engineered structures.
Details regarding my educational and professional background are summarized below.
