For his solid waste, industrial and mining clients, David has performed geotechnical engineering evaluations slope stability analysis, embankment and mechanically stabilized earth walls design, drainage systems and geotechnical monitoring plans. His project sites have included locations where weak soil conditions prevented standard design techniques. David's experience includes a strong background in the design and use of geosynthetic materials as hydraulic barriers, subsurface drainage, and embankment reinforcement applications. His in-depth understanding of numerical models and geomechanics allowed him to model complicated soil-structure interaction conditions that led to design recommendations successfully executed in the field. David has also performed forensic investigation of failures and provided technical consultation on litigation activities for geoenvironmental projects.
More recently, David's capabilities have expanded into decision analysis and financial evaluation areas. David has developed unique quantitative methods that allows decision makers to account for technical risk along with financial risks using state of the art financial theory. He has authored several papers on engineering and finance that have been published in peer-reviewed journals and financial newspapers such as the Financial Times.
