45 years experience in geological engineering for mines, heavy construction and roadway construction. Background includes coal and metal mining (slope stability and ground control); geotechnical and mineral exploration (drilling, sampling, geochemistry, geophysics; laboratory testing of rock, soil and construction materials (mineral content, geotechnical parameters, or quality control); hard rock tunneling; abandoned mine remediation and investigation; conventional soil and foundation engineering for bridges, walls, and commercial developments; heavy highway construction with emphasis on large cut and fill projects and deep foundation problems; forensic analysis and expert witness services; troubleshooting and problem solving in applied engineering geology and geological engineering.My approach has always been holistic, integrating aspects of the overall construction process to alleviate constraints such as aesthetic requirements, environmental complexities, public participation, traffic, or regulatory issues.I prefer hands-on involvement, working closely with contractors and practitioners in the field, supported by office engineering and analysis. I feel strongly that designers should follow through into construction, to provide a proper foundation for engineering design.Specialties: Rock excavation and blasting techniques, control of construction disturbance and vibrations, applied rock mechanics, soil and foundation engineering, specialty problems in geotechnical engineering.
