David Espinoza is a Senior Principal Geoenvironmental Engineer based in Maryland focused on foundation design over soft soils, design of regulated containment facilities, and more recently, financial evaluation of infrastructure investments taking into consideration physical risks such as climate change.
David's solid waste experience includes permitting of disposal facilities for municipal solid waste, construction demolition debris, and industrial manufacturing wastes/residuals; design of the full range of components for containment facilities such as stormwater systems, leachate collection systems, and landfill gas collection. David has prepared and executed field exploration programs, groundwater monitoring programs, and permit applications. He has performed detailed engineering designs and evaluations for lining systems, bioreactor systems, including leachate recirculation, and he has prepared landfill and surface impoundment closure plans. He has also designed landfill gas systems.
For solid waste, industrial and mining clients, David has performed geotechnical engineering evaluations of settlements, slope stability, embankment design, and mechanically stabilized earth walls. His project sites have included locations where weak soil conditions exist to support foundations, such as dredge disposal facilities and industrial sludge. 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 allowed him to model complicated soil-structure interaction conditions and provide design recommendations that have been successfully executed in the field. David has also provided technical consultation on litigation activities for geoenvironmental projects.
More recently, David’s consulting experience has included the evaluation of the economic feasibility of geoenvironmental-related projects, as well as the economical evaluation of projects for reduction of carbon emissions in the United States and South America. David is active in the development of quantitative methods for the evaluation of environmental risk projects 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.
