THP has designed economical structures for facilities in the high seismic areas of the Pacific Northwest, Alaska, and the Asian Pacific.

We excel in retrofitting existing facilities for earthquake protection which often requires more innovation and creativity than designing for new construction. Our retrofits include:

  • • Installation of numerous viscous dampers in Taiwan to improve
    the safety and performance of the facilities during a major
    seismic event.
  • • Seismic risk analysis and reinforcement of highly sensitive
    production lines in China, Japan, and Taiwan to allow production
    continuity after major earthquakes.
  • • Seismic upgrade of a 100 year old, 4-story building housing a
    data center by applying reinforced shotcrete shear walls to the
    interior of the exterior bearing walls while the center was kept in
    continuous operation. This facility is near the New Madrid Fault.
