Gerwick regularly performs seismic analyses/designs and is considered one of the COWI Group's Centers of Excellence for seismic analyses/design.
We have extensive experience with seismic analysis and design using various codes from various countries. Our technical professionals will choose the most appropriate seismic analysis method for the bridge type.  Most often, our engineers use SAP2000 to perform Multimodal Spectral (Elastic) analysis and use the step-by-step Time-History method when analyzing critical bridges in regions with the most intense earthquakes.
