Expertise DescriptionI have over 35 years experience in Geotechnical and Pavement Engineering, performing and supervising subsurface investigations as well as field and laboratory testing in soils and rocks. My soil engineering projects involve earthwork including site development and foundation investigations, slope stability, retaining wall systems, soil stabilization and foundation repair, performance of pavements and subgrade conditions, soil compaction and its associated properties, seepage and impoundment failures, subsidence / settlement damage, ground movement, soil excavation, soil sampling, soil-structure interaction, as well as other soil mechanics and foundation problems. My forensic and engineering projects in rock include stability and support of underground working in salt, coal, and hard rock; grouting; rock excavation behavior and difficulty; subsidence engineering; and seepage in rock. I have more than 25 years expert witness experience with consultations, deposition, and courtroom testimony.
Areas of Expertise
My expert witness experience includes numerous Geotechnical / Civil Engineering subjects.
My consulting services include: forensic engineering, with the analysis of groundwater seepage, investigation of earth and concrete dam failures, rock hardness evaluation, evaluation of pavement failures, and the evaluation of mine backfilling conditions; geotechnical research engineering, with foundation feasibility studies and designs for various types of structures, foundation evaluation and design over shallow abandoned coal workings, field feasibility study and inspection of caissons for high-rise building, analysis of ground conditions and construction difficulties for deep foundation projects, and slope stability and stabilization; project engineering, soils engineering, and research experience, with the design and implementation of abatement of procedures against hazards from subsidences, development of advanced reconstruction procedures for subsidence-damaged homes, and evaluation of geophysical data for assessment of geologic and geotechnical site conditions.
Working in the area of mine subsidence for over 36 years in various ore fields in the U.S., I have researched and consulted on all aspects of subsidence engineering with government agencies, engineering and architectural firms, and surface owners, as well as pipeline, insurance, and mining companies. My work includes planning, mining, and abandonment stages of room and pillar to high extraction workings, as well as related cause and origin investigations.
Over the course of my career, I have authored over 100 articles and publications on subsidence engineering topics.
