Lincoln EH. Influence of geologic conditions on building foundation engineering in Boston, Massachusetts. Senior honors thesis, Harvard University, 1978.
Evaluated causes of landslides and storm damage including bridge collapses and culvert failures.
Served as project geologist for integrity analysis of recently constructed parallel pipelines carrying natural gas and liquid natural gas (LNG) from the Amazon jungle over the Andes mountain range to the Pacific coast of Peru. Reviewed pre- and post-construction geologic and geotechnical reports (primarily in Spanish); performed site inspections at 49 remote locations at which repairs of landslides, rockslides, debris flows, and eroded river banks were planned or in progress; evaluated factors that contributed to the occurrence of six LNG pipeline spill incidents, evaluated geotechnical-related risks to the pipelines; evaluated the pipeline operator’s progress toward reducing the risks; and prepared geologic and geotechnical portions of several reports and presentations.
Evaluated reported sinkhole-related damage to a large condominium complex in Tennessee. Coordinated work of Exponent staff, geophysical subsconsultant, and construction cost estimator, and served as liaison with local geotechnical consultant.
Evaluated causes of sinkholes that formed above newly constructed storm drain on State highway project in California’s Central Valley. Investigation included extensive review of contractor’s and inspector’s daily logs prepared during construction.
Performed down-hole logging of large-diameter drill holes in landslides and beneath distressed houses to examine soil and bedrock for evidence of landsliding, to determine depths and physical characteristics of slide planes, and to collect samples of slide-plane material for laboratory testing and subsequent stability analysis. During construction of foundation underpinning, examined sidewalls of pier holes to determine whether embedment was adequate.
Investigated stability of a large landslide beneath a proposed rocket-fuel mixing facility. Work included literature research, air-photo interpretation, geologic field mapping, and logging and sampling of continuous-core drill holes.
Evaluated causes of earthquake-induced ground failures at private residences and government facilities after the 1989 Loma Prieta Earthquake in the San Francisco Bay area. Ground failures investigated included landslides, ridge-top shattering, deformation of fill, and lateral spread due to liquefaction. Investigated earthquake damage claims after the 1994 Northridge Earthquake in southern California. Evaluated claim of earthquake damage to a water main in a high-rise building after a minor earthquake in Los Angeles. Analyzed extent of damage to a government facility due to liquefaction and lateral spread caused by the 2006 Hawaii earthquake.
Evaluated the merits of subsurface differing site conditions claims on public highway and sewer projects in California’s Central Valley and the Sierra Nevada foothills.
Performed numerous investigations, including: Distressed houses, hillside ranch roads, landslide and debris-flow causation, erosion damage causation, diversion of drainage, over-excavation in quarries, archaeological sites, billing disputes, differing site conditions claims, and a fatal car crash. Work included review of available geologic and engineering information, air photo interpretation, geologic mapping, crawl-space inspections, observation during remedial construction, document review, and presentation of findings.
Performed detailed interpretation of historic aerial photographs of two former oil fields to determine site use history, topographic (development) history including drainage routes, sources and geometry of fill material, and sources and distribution of debris. Correlated air photo findings with historic site plans and descriptions from deposition transcripts.
Provided technical and project management support to assist a Southern California client in identifying, prioritizing, and evaluating potential sources of perchlorate to a municipal well field.
Provided technical and project management support for an environmental cost recovery claim related to discovery of lead impact to soil at a former military base in southern California.
Provided technical support for evaluation of alleged damages to a Central Valley (California) municipality's sole water-supply aquifer from releases of PCE.
Provided technical support for evaluation of allegations of releases of PCE at more than 30 separate locations in a northern California municipality.
Performed numerous Phase I Environmental Site Assessments, including determination of site history from air photos, historic documents, and interviews; site inspections and chemical storage inventories; assessment of nearby facilities; and analysis of potential for existing and future soil and ground water contamination.
Designed and installed monitoring wells at numerous fuel and solvent storage facilities. Conducted soil and ground water sampling and evaluated lateral and vertical extent of various chemicals of interest.
Prepared geologic and ground movement potential maps for the City of Saratoga, California, and geotechnical hazards maps for the City of Milpitas, California.
Supervised fault-rupture hazard investigations, including logging of exploratory trenches to investigate fault locations and activity. Projects ranged from school sites on faults in Alquist-Priolo Earthquake Fault Zones to single-family houses adjacent to newly mapped faults.
Performed development-feasibility mapping of large ranches proposed for residential development. Prepared geologic maps and cross sections; evaluated fault, landslide, debris flow, and liquefaction hazards; and constructed development feasibility maps. Served as liaison between clients and agency planning departments.
Performed office and field review of landslide investigation on behalf of subdivision developer’s geologic consultant. Objective was to develop an independent interpretation of unexpected subsurface conditions before consultant submitted report to reviewing agency.
