The Provo Utah Temple and Provo City Center Temple were the second pair of temples to be built in the same city, following the Jordan River Utah Temple (1981) and Oquirrh Mountain Utah Temple (2009) in South Jordan, Utah. Block-outs were formed in the foundation walls around each of the shoring needle beams (Figure 5). The structure serves a much different purpose than a chapel where regular worship services are conducted. In many areas, the need for thin concrete walls resulted in shear walls and boundary elements that did not comply with prescriptive code requirements.

The proposed shoring system would need to ensure placement of the waterproofing membrane below the sub-basement floor and at the exterior face of the foundation walls without compromising the performance of the membrane under significant hydrostatic pressure. It also had to allow placement of new reinforced shotcrete walls against the interior face of the brick. It engages, enlightens, and empowers structural engineers through interesting, informative, and inspirational content. This temple is among the busiest in the LDS Church due to its proximity to BYU and the MTC. To help the owner gain confidence in the thinner walls performing as desired during an earthquake, the structural engineers completed a performance-based design using non-linear analysis techniques. First, they temporarily supported the exterior brick walls.

The renovation itself will remain a remarkable feat to those who watched every stage of the project. As excavation progressed, steel diagonal braces were added between the micro-piles to provide lateral stability and maintain the allowable unbraced length of the micro-piles. A series of eight-inch diameter micro-piles were drilled into the ground, on each side of the walls, to a depth of about 90 feet. PHASE 2: TEMPLE OPEN FOR LIVING ORDINANCES ONLY—Based on First Presidency direction, this temple has resumed limited operations. HISTORIC RENOVATION Provo City Center Utah LDS Temple Dedicated in 1898, the Provo Tabernacle was an impressive structure of its time, featuring octagonal towers at all four corners, a high-pitched roof, exquisite woodwork, and room to seat 1,500. The dowel system was designed to transfer forces between the walls and the floors, which serve as horizontal diaphragms while providing ductile behavior during an earthquake.
