ENGEO’s engineers incorporate state-of-the-art methods and expertise to perform site-specific geotechnical earthquake engineering to precisely quantify seismic hazards, optimize designs, and apply performance-based engineering.

Design and retrofit of buildings in urban cores of seismically vulnerable regions present a number of unique seismic, geotechnical, geologic, and constructability challenges. The engineers and semiologists at ENGEO develop precise methodologies for performing seismic-hazard and site-response analyses for new structures and existing buildings. These approaches provide optimized earthquake engineering, typically resulting in much more efficient superstructure designs. 

ENGEO routinely collaborates with regulatory agencies throughout the US and abroad to achieve project goals. We maintain amiable and professional relationships on which our clients rely to represent their needs in complying with complex State and Federal guidelines. Our ability to navigate the regulatory process on behalf of our clients has been instrumental to achieving timely permitting and project advancement. 

Our earthquake engineering analyses have been peer reviewed by highly respected technical panels composed of leading authorities in the field of earthquake engineering.

We specialize in the following analyses: 
  • Non-Ergodic and Ergodic Site-specific Seismic Hazard Analyses 
  • One- and Two-Dimensional Site-Response Analyses
  • Ground Motion Time History Development 
  • Soil-Structure Interaction Analyses 
  • Dynamic Slope Stability Evaluations 
  • Optimized Analyses of Earthquake-Induced Liquefaction and Settlement 
  • Site Period Determination based on Horizontal-to-Vertical Spectral Ratio Geophysical Testing
