2026 Fall Forum: Preserving History Through Seismic Innovation

About this event

Join Structural Engineers Foundation of Washington for an in-depth look at one of the most significant historic preservation and seismic retrofit projects in North America — the renovation of the historic Salt Lake Temple. Originally completed in 1893, the Temple has undergone several renovations throughout its history. In 2019, a comprehensive modernization and seismic strengthening program was announced to address aging infrastructure, enhance life safety, and improve the building’s resilience to future earthquakes while preserving its historic and architectural significance. This presentation will explore the innovative engineering solutions being implemented as part of the renovation, including state-of-the-art base isolation systems, post-tensioning of the stone masonry walls, and extensive structural reinforcement of the roof and supporting elements. Attendees will gain insight into the challenges of upgrading a complex historic structure in a high-seismic region while maintaining its original character and craftsmanship. Scheduled to reopen in early 2027, the Salt Lake Temple renovation serves as a remarkable example of how modern engineering can preserve history while preparing iconic structures for future generations. This session will provide valuable lessons for engineers, architects, and preservation professionals involved in the rehabilitation and seismic strengthening of existing buildings. Events are offered for informational, entertainment, and educational purposes only. Read Town Hall’s Program Content Policy.
