Seismic Engineering
The Pacific Northwest has dense population centers along the west coast and the region is at significant risk from a full rupture Mw 9.0+ Cascadia Subduction Zone Earthquake. Our understanding of the regional seismicity and its impact on infrastructure is continually increasing with research and new developments from the professional and academic communities. The geotechnical industry continues to evolve as these new developments are incorporated into design criteria and building codes. GRI has immersed our team into researching, code development, monitoring, and providing peer review to improve the industry understanding of seismic analyses and design.
Our team is actively involved in national committees on seismic design, writing papers addressing cutting-edge geotechnical practice, and actively participating in research on soil-structure interaction, ground motion studies, and the cyclic behavior of local silts and deep sand deposits.
Our team provides the full range of seismic analyses and design services, including site-specific seismic hazard evaluations, ground motions studies, soil-structure interaction, liquefaction potential, and seismic risk analyses. A core area of firm expertise involves the integration of the varying performance-based design standards to develop project specific design standards for multi-modal and other unique facilities.
Our seismic experts have applied their expertise in supporting public safety by evaluating seismic design for lifeline structures throughout the Pacific Northwest. GRI prioritizes the owner’s seismic performance objectives, resilient designs, and cost-effective strategies to prepare our clients and their infrastructure to withstand a seismic event.
