Mr. Korkos has over 35 years of experience conducting geotechnical studies for highway and railroad bridges, roadways and pavement, rail track improvements, flood control facilities (including open channels, culverts, basins, levees, and pump stations), earth retaining structures, and buildings. Andrew has experience in foundation design for various types of structures, and design and construction of various types of earth retaining walls including conventional cast-in-place cantilevered walls, Mechanically Stabilized Earth walls, ground anchor walls, soil nail walls, soldier pile walls, and secant pile walls. Andrew has managed projects of all sizes, ranging from relatively small hiking trail projects to large roadway projects to the Mid-Corridor Trench Design-Build project for the Alameda Corridor that had a $1.1 million geotechnical budget. Andrew has significant design experience with large mass grading projects including evaluating settlement of deep fills and stability of cut and fill slopes, and developing remedial measures for slope stabilization; he works together with engineering geologists to develop solid solutions for slope stabilization. Andrew has practical field grading experience in observing excavations and compacted fill placement. Prior to joining Earth Mechanics, he worked at the Orange County Public Works Materials Laboratory gaining considerable experience in pavement and roadway design and construction. Andrew is familiar with Caltrans, AASHTO, FHWA, and AREMA design and construction guidelines.

Areas of functional responsibility include managing projects and coordinating with clients: planning and managing field investigations and laboratory testing programs; reviewing and conducting geotechnical analyses and providing design parameters and recommendations; preparing reports, and providing technical support during construction.
