EMI can provide comprehensive geotechnical services to the City, from the feasibility stage to the construction stage, including accomplishing geotechnical field explorations and laboratory testing, infiltration testing, conducting geotechnical analyses, and developing design and construction recommendations for the City's future improvements. In addition, EMI has experience in landslide and slope stabilization, ground motion studies, evaluation of seismic hazards including seismically -induced landsliding, seismically -induced settlement, and liquefaction potential. EMI has accomplished many geotechnical investigations throughout the City of Santa Ana and Orange County, and, as a result, we are familiar with the geology and soils throughout the City. We believe EMI provides a well -qualified team that has earned a reputation for delivering cost- effective geotechnical solutions to public projects in the City. • Proven Project Manager — The designated project manager, Mr. Raj Pirathiviraj, has worked on multiple projects in the City and surrounding areas and is familiar with the protocols and standards.
