Overview of project as of 29 March 24 during TG pour

Please join us to learn about updates to the Salt Lake Temple.

Significant progress has been made on this project with respect to the new seismic foundations of the historic Temple. In this presentation, a detailed update will convey how the existing stone foundations of the Temple have been consolidated in preparation for the new, deep, and heavily reinforced concrete seismic upgrade.

The focus will be on the installation of 98 base isolators, the large concrete transfer girders that encase the existing foundations, and the role of post-tensioned cables in and through the new and existing foundations, as well as vertically inside the columns of the building. These enhancements are designed to strengthen unreinforced stone walls and transform the historic Temple into a solid edifice capable of moving 5 feet in any direction in the event of a serious seismic event.
