Managing Engineer

Los Angeles

Ms. Doyel brings 32 years of experience in geotechnical analyses, planning and design geotechnical studies for land development, public and private infrastructure, and construction projects, working in a variety of environments including land, coastal, nearshore marine and offshore marine. Her career included 18 years of marine and 24 years of construction experience and provides an unusual breadth of experience in both onshore and nearshore environments, and national and international work. She has performed extensive geotechnical analyses of property damage due to landslides, earthquakes, floods, expansive soils, construction defects, differing site condition claims, construction failure of drainage systems, pipelines, excavations, slopes, and retaining structures, and evaluation of environmental pollution source and migration in soil and groundwater. For the last 20 years Ms. Doyel has focused on public works infrastructure, providing project peer review, technical evaluation, design studies and construction oversight for a variety of projects for city, county and federal agencies as well as for universities, school districts, utilities and private parties. She spent eight years working as Fugro’s geotechnical services manager in the Ports of Los Angeles and Long Beach, during which she developed extensive knowledge of local geotechnical and as-built conditions and hazards, and of marine investigation and construction techniques, including dredging.

Ms. Doyel’s training in land use planning and geology provides her a unique geotechnical engineering perspective and informs her approach to technical evaluation of projects. She has extensive experience in evaluating large and small scale natural and man-made embankments, excavations, reservoirs, pipelines, pavements and shallow and deep foundations. Large-scale failures include levees, coastal landslides and flooding due to man-made and natural changes in drainages. She has extensive experience with evaluations of the cause and origin of failures, construction claim evaluation, and peer review of structures and land development. This experience includes claims due to changed conditions, construction methods and sequencing, and construction delays. She has extensive experience in city planning and building regulations in suburban and highly urbanized areas where change in land use and redevelopment are often limiting factors in development. She has evaluated foundation and ground failures in large tract development, public works projects, and commercial and industrial developments due to construction defects, grading defects, settlement, subsidence, flooding, expansive rocks, expansive soils, ground vibrations and earthquakes.

For over 10 years, Ms. Doyel was the coastal engineering consultant for the City of Malibu, during which she was responsible for reviewing development projects in the coastal zone, providing recommendations for coastal engineering standards to be included in the City’s Local Coastal Plan (2002) and developing the first city standards for coastal engineering reports to be submitted for review. Working closely with the planning and building and safety departments, she was the first to advocate for incorporating sea level rise and tsunami run-up in project planning standards and review. In addition, while at Fugro, her exposure to their global, nearshore marine surveying and exploration services allowed her to provide the City a national and international perspective on changes in the coastal environment and anticipated effects on the City’s 27 miles of coastline, especially during evaluation of accelerating coastal erosion issues and Emergency Coastal Development Permits.

During her career, in addition to Project Engineer and Manager, she has been in responsible charge as: Principal Engineer for a California Division of the State Architect (DSA) certified lab and Geotechnical Engineer of Record for design and construction testing on DSA certified school projects; Principal Geotechnical and Coastal Engineering Peer Reviewer for the City of Malibu and Principal Geotechnical Peer Reviewer for a half dozen other southern California cities; Engineering Group Manager for Fugro’s Nearshore Geotechnical practice in southern California; and Contract and Service Manager for Geotechnical Services contracts with the Army Corp of Engineers, US Navy, and Port of Los Angeles.

Her design specialties include large project single point responsibility for integrated geotechnical services for projects from planning and design through construction phase, management of construction observation and testing services for private and public clients, marine environmental and geotechnical engineering studies for dredging, and coastal and geotechnical peer review of land and coastal development. She has been responsible for project planning, execution and management of geotechnical studies, geotechnical site characterization, scopes of work, and budgets for new projects; technical report preparation and review, geotechnical hazard characterization and engineering analyses for site development, and construction phase support services, including grading and construction materials testing.
