Ms. Doyel brings over 30 years of experience in geologic and geotechnical studies for land development, infrastructure, and construction projects in southern California, working across all service lines including onshore and offshore geotechnical, municipal services, marine survey, construction, and forensics. Recently, she has provided geotechnical engineering consultation and forensic investigation/evaluation of and expert reports for: construction failures and accidents, residential damage due to fires, earth movement, pipeline failures, floods, and gas explosions.  Clients include law firms, insurance companies and utility companies. Recent failures evaluated include Montecito mudflows, the La Tuna, Creek, Thomas and Skirball Fires, and backfill and pavement failures related to gas pipelines.

She has provided technical evaluation and design studies for a variety of onshore and coastal geotechnical infrastructure projects, and geotechnical oversight of construction for federal, state and local governments, universities, school districts, utilities and private parties. She is adept at pursuing, winning and managing both large and small project contracts, as well as on-call contracts due to her ability to identify key relationships, critical project elements, and provide project approaches that stand out.

Ms. Doyel’s skills include project planning, execution and management of geotechnical studies for a variety of structures and clients, geotechnical site characterization, proposal creation and presentation, scopes of work, and budgets for new projects;  technical report preparation and review of; engineering analyses for foundation design, slope stability and seismic hazards;  construction phase support services, including review of construction plans;  forensic analysis of construction and slope failures; and mentoring staff engineers and technicians in basic engineering procedures and techniques. She is a practiced public speaker before both technical and non-technical audiences, from City Councils to Homeowner Associations. Her proposal presentation skills, individually and as part of a team, have often been noted by clients as a factor in award. She recently co-presented an online webinar “Ground Failures and Other Ground-Water Related Property Damage” as part of the Lorman Technical training program (

She has focused on public works infrastructure since 1999, from project planning and design studies through construction, and in the last 5 years she has also managed private land development projects.  In addition to her roles as project engineer and manager, she has excelled as principal geotechnical and coastal engineering peer reviewer for the City of Malibu, geotechnical laboratory manager, DSA Engineer of Record, and engineering group manager.  Her 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, marine and fresh water environmental and geotechnical engineering site characterization studies for dredging, coastal and geotechnical peer review of land and coastal development, and forensic project studies.
