Our experience in a number of industries; power generation, transportation, urban development, and on diverse project categories such as; dams, hydraulic structures, nuclear power plants, fossil and renewable power plants of various vendors, and infrastructure projects enables us to provide economical solutions tailored to the project types in a timely manner. Our engineers are experts in working in heavily regulated and non-regulated industries.

Our geotechnical project managers “stay close” to our clients to respond quickly for ever changing conditions of the projects. RIZZO’s QHSE program originated from strict Nuclear Industry requirements that satisfies QA/QC standards for other industries and, always, exceeds Clients’ expectations.

Rizzo’s engineers are not only experts on utilizing all available geotechnical software (Plaxis, Flac, GeoStudio, Ansys, gINT, LPILE etc.) but also experts on 3D ground modelling (e.g. Rockworks), GIS based mapping (e.g. ArcGIS) and risk assessment software. We can design and implement custom solutions for specific needs.

RIZZO’s Geotechnical Engineering reaches all corners of the world and applies state-of-the-art practices of the civil engineering field.
