Ivan Contreras

Headshot of Ivan Contreras

Iván has more than three decades of geotechnical engineering and project management experience for projects in the United States, Canada, and Central and South America. This work has ranged from the conceptual design of small reservoirs to detailed design of oil-storage-tank foundations and slope-stability remediation. Iván has managed contracting, consulting, inspecting, forensic, and research projects. He lends his expertise in the areas of mine tailings-dam design and management; embankment, slope, foundation, tunnel, and underground structure design; landslide stabilization; ground improvement and grouting; soil dynamics and earthquake engineering; dredged material management; and in-situ testing.
