Seismic Upgrading is typically a more owner or occupancy change driven approach versus mandatory ordinance driven by jurisdictions. With Zenith's experience retrofitting over 600 buildings on the west coast you can be rest assured that we are only designing what needs to be done and what is required.

Whether it's a concrete tilt up, unreinforced masonry, non-ductile concrete, or soft story building, we have the technical know-how to support you through concept all the way to permit and through construction administration. The construction efforts of seismically upgrading a building is so specialized, it's good to have an independent engineer on your side guiding you through the construction process.
