California’s aging building stock, strict seismic regulations, and high-density urban environments have made seismic retrofitting one of the most critical priorities in the Architecture, Engineering, and Construction (AEC) industry. From hospitals and schools to commercial high-rises and municipal buildings, owners are under increasing pressure to improve structural resilience while minimizing project delays and budget overruns.
