DARCIE A. MAFFIOLI, P.E., G.E.

SENIOR ENGINEER

Ms. Maffioli has performed geotechnical investigations and studies to develop geotechnical recommendations for the design and construction of low-rise to high-rise residential and commercial developments, educational facilities, and affordable housing projects. She has provided geotechnical recommendations to mitigate geologic hazards, such as liquefaction, lateral spreading, and unstable slopes. She has also participated in design optimization projects, feasibility studies, litigation, and peer reviews for complex geotechnical projects.

Ms. Maffioli has evaluated sites with complex subsurface conditions, including undocumented fill, weak and highly compressible soils, and potentially liquefiable soils. She has developed design recommendations for deep and shallow foundations, temporary shoring and retaining walls, and ground improvement systems. She has performed site-specific ground motion studies and site response analyses. She has also installed and assessed the performance of subsurface instrumentation, such as inclinometers, extensometers, and piezometers.
