As part of the Salt Lake Temple renovation project, a tunnel is being constructed underneath North Temple to connect the Conference Center parking lot to the underground facilities and entrance to the temple. The tunnel excavation is about 80 percent complete. These photos show the steel arches that are encased in shotcrete (a form of grout) to create the initial lining of the tunnel walls. The steel arches are spaced 4 feet (1.2 meters) apart. The drilling machine is used to remove the upper portion of soil, which is then hauled away by an excavator. This also removes the lower portion of the excavation as shown in the third photo below.

The secant walls are installed as close to the bottom edge of the existing footings as possible to contain and brace them in place. The secant wall is built by drilling deep holes where alternating steel and concrete columns are installed. These overlap with each other to create the retaining wall.

The upper stones of the temple walls are being gradually removed to prepare for the structural concrete bonding beams that will brace the walls. The stones that are removed will be reinstalled in their original positions.

In this photo, workers help the tower crane operator guide the stone to placement for transportation and storage.
