We excel at seismic design, investigation, repairs, and rehabilitation.  We provide both code-based and performance-based earthquake engineering services.  We recently completed the performance-based engineering for the seismic upgrade of Boeing's high-bay assembly building in Everett, Washington, where they make the 747, 767 and 777 airliners.  This factory has the distinction of being the world's largest building.  We developed performance-based design criteria and used non-linear dynamic time-history analysis for the investigation and design phases.  The final design solution used non-linear friction dampers to control and dissipate seismic loads.   We are confident in our ability to handle any size project.
