The lagging shown in the next photo, used to prevent cave-ins, helps contain all the soil pressure from the surrounding areas as the crews begin deeper excavation in preparation to construct three lower levels of the temple. These floors will include temple maintenance facilities, two baptistries, dressing rooms, sealing rooms, administrative offices, and more. As the depth of the retaining wall increases, additional walers (horizontal steel beams) are added to strengthen the structure.

The secant walls and buttresses shown below are reminiscent of fortresses. They contain the soil and hold the foundation of the temple in place in preparation for jack and bore drilling under the existing footings of the temple. This process will begin in August to prepare for the new foundation that will encase the existing foundation of the temple and the base isolators designed to resist seismic events.

As announced in June 2021, the North Visitors’ Center has been decommissioned. All art, exhibits, and artifacts in the building have been removed. The “Christus” statue was carefully boxed and removed by a crane on Monday, July 12, 2021. It will be placed in storage for preservation and will return to Temple Square at the end of the renovation process.
June 2021 Construction Update
Newsroom published the following construction update on June 21, 2021.
The Salt Lake Temple has been closed for renovation since December 2019. The Church Office Building plaza closed for an upgrade in February 2021. The following is the latest in a series of regular updates about these projects.
Over the past month and a half, four steel trusses have been added to the roof of the Salt Lake Temple.
The existing steel trusses (painted yellow in the photos below) will remain and are paired, side by side, with the new trusses as part of the seismic design of the temple. The new trusses are erected two at a time to control the exposure of the existing roof. Each new truss weighs about 35,000 pounds (15 metric tons) and is 88 feet (27 meters) long at the bottom. Once a pair of new trusses is in place, cross bracing is installed to immediately provide lateral bracing. The bracing is not welded in place but secured by nuts and bolts to avoid the risk of fire.
Crews prepare to place a new truss on the temple. New trusses weigh about 35,000 lbs or about 15 metric tons and is 88 feet long or 27 meters long at the bottom, Salt Lake City, June 2021.

The deep secant wall, with buttresses that were previously built, is being gradually exposed to prepare for further deep excavation needed to construct three additional floors of the temple facilities. These facilities will be directly north of the temple and include the baptismal fonts, additional sealing rooms, dressing rooms, administrative offices and so forth. The buttresses of the secant wall will also resist the loads and lateral forces from the massive weight of the temple, which exceeds 185 million pounds (84,000 metric tons).
Further excavation is planned on the Temple, which weighs more than 185 million pounds or 84,000 metric tons, Salt Lake City, June 2021.
The previously built buttresses on a deep secant wall are gradually exposed to prepare for more excavation needed to construct three additional floors of the temple facilities, Salt Lake City, June 2021.
In addition, large horizontal steel beams, called walers, are installed to further brace and strengthen the steel and concrete columns that form the secant wall. Post-tensioned cables run through the walers and add pressure against the secant wall. This helps resist the soil pressure that naturally increases with depth. The depth of the secant wall is approximately 80 feet (24 meters). Excavation will continue until it reaches the depth of the bottom of the new lower third floor of the additional facilities.

The tunnel underneath North Temple street that will connect the Conference Center parking to the new second floor of the temple is now complete up to the wall of the Conference Center parking garage. The tunnel wall is lined with concrete, and the floor is now a structural concrete slab. The tunnel will be excavated into the Conference Center parking lot in the coming months. Below is a view of the Salt Lake Temple from the tunnel underneath North Temple street.

May 2021 Construction Update
Newsroom published the following construction update on May 6, 2021.
Crews have reached the end of a new 180-foot-long (55 meters) tunnel underneath North Temple street that will connect the Conference Center parking lot to the new underground temple entrance. The final work of removing the concrete wall that leads into the Conference Center parking structure will be done later.
Workers recently began placing scaffolding on the west and north sides of the temple. The photo below is of the north wall. Scaffolding already covers the south side and will eventually surround the entire structure.
Crews continue to remove rows of stones from the temple walls for repair and cleaning. Each stone is carefully labeled and will be returned to its original spot.
To keep Salt Lake City clean, the renovation site has a truck washing bay. Before vehicles exit the temple renovation site onto South Temple street, wheels, axles, mud flaps, and other parts of each vehicle are thoroughly sprayed.
The photo below shows the progress of the excavation on the north side of the temple. The tunnel (shown in the first two photos above) is on the far left. In the middle is the preparation for the tower crane. This crane will be in place after the crane concrete foundation is poured. Lagging surrounds the site to keep soil in place.
This photo looks west at the renovation of the Church Office Building plaza. The Church Administration Building (left), the Joseph Smith Memorial Building (middle) and Church Office Building (right) are also shown. Crews are using conveyor belts to move soil and debris to a truck loading location. Trucks enter the site from North Temple and exit onto South Temple.
Finally, below are several square-headed nails that crews have found in the temple. These show some of the workmanship and materials used to build the Salt Lake Temple, which was finished in 1893. The longest nails are six inches (15 centimeters) long and show few signs of corrosion.
April 2021 Construction Update
Newsroom published the following construction update regarding work performed thus far in April 2021.
16 April 2021
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 temple is now surrounded on three sides by a secant wall. 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 copper roof sheathing of the temple has been completely removed and replaced with a temporary roof. This is in preparation for the installation of additional steel trusses, an important part of the seismic strengthening of the temple.
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.
When workers need to access the higher levels of the towers, they use a variety of safety measures, such as mandatory harnesses, to prevent falls. Harnesses are tied to existing hooks anchored in stones.
As stones are removed from the temple for repair and cleaning, workers ensure they are properly cataloged and labeled so they can be returned to their exact original placement. In this photo, workers help the tower crane operator guide the stone to placement for transportation and storage.
On the Church Office Building plaza, multiple conveyor belts help carry materials and debris for hauling off-site. The two fountains are being removed, along with walkways and planter boxes.
March 2021 Construction Update
Newsroom published the following construction update regarding work performed in March 2021.
26 March 2021
This week on the Salt Lake Temple renovation project:
The excavation to create a tunnel underneath North Temple is underway. This tunnel will connect the Conference Center parking lot to the underground temple entrance to create safer and easier access for visitors to the temple. Previously, canopy tubes were installed at the upper perimeter of the tunnel to provide a support frame before drilling and excavation began. The excavation is now about halfway complete.
The worker and material lift continue to be assembled. Workers are now constructing scaffolding bridges that will connect the lift to the scaffolding, which will surround the entire temple. The lift will provide access to the various floors of the temple.
The work to remove the current temple roof and provide a temporary cover is about halfway through.
The Church Office Building Plaza has undergone a significant change. Most of the area surrounding the fountain has been excavated in preparation for significant restructuring and landscaping work.
A construction road made of recycled asphalt has been completed through the Church Office Building Plaza area from North Temple to South Temple to accommodate the movement of construction equipment and large trucks.

Update on Salt Lake Temple Renovation
In a press release published on March 12, 2021, the First Presidency provided an update on the Salt Lake Temple Renovation which included some changes to the project. The press release included details such as:
- • Two more instruction rooms, additional sealing ordinance rooms, and a second baptistry are being added to allow for greater capacity and more temple ordinances.
- • Previously, the member experience in this temple included a progressive room-to-room presentation by live actors. When the temple reopens, this will transition to single-room presentations by film, available in more than 80 languages (previously presented only in English). This decision will also make it possible to hold more sessions each day. And finally, we hope it will help more members feel confident to serve as ordinance workers without the requirement for lengthy memorization.
- • The area that previously housed the temple cafeteria will now accommodate additional temple facilities to support the increased capacity of the temple. There will not be a cafeteria included when the temple reopens.

February 2021 Construction Update
Newsroom published the following construction update regarding work performed in February 2021.
19 February 2021
Many of the stones on the top of the temple walls are being carefully removed for cleaning, preservation and short-term storage. They are labeled so they can be returned to their original places.
Work continues on the drilling underneath North Temple to provide for an underground entrance to the temple from the Conference Center parking structure.
In this photo below, drilling on the temple side consists of installing canopy tubes to create a structure that will support further excavation.
In this photo below, the parking structure is being shored up on the Conference Center side.
As part of the seismic upgrade of the temple, the existing roof is also being upgraded. The roof will be gradually removed and have a temporary covering (similar to a heavy-duty tarp) until the new roof is completed.
In this photo below, the south tower crane is lifting the temporary roof cover.
The plaza work that was announced in January 2021 is now visibly underway. The area between the Church Administration Building and the Joseph Smith Memorial Building is being used as a road to help move materials in and out of the plaza as the renovation continues.
5 February 2021
As part of the Salt Lake Temple renovation project, the grounds around the temple are also being renovated. In January, construction began on the Church Office Building plaza. Temporary fencing was first put in place, which has been followed by more permanent fencing.
Crews continue to work on preparing for the construction of the tunnel that will run underneath North Temple from the Conference Center parking structure to the future underground entrance to the temple. This involves drilling canopy tubes that form shoring support.
Near the southwest corner of the temple, shoring and excavation are complete for the installation of a worker/material lift. Due to the proximity to the foundation of the temple, the shoring ensures the lift excavation does not disturb the temple foundation. The lift will allow for easier access of workers and materials into the interior of the temple’s upper floors.
The stones along the upper walls of the temple are all being removed. As they are lifted off with a crane and placed in the ground, they are labeled. These will be placed in storage, cleaned, and repaired, and will ultimately return to their original places.
January 2021 Construction Update
Temple Square published the following construction update regarding work performed in January 2021.
22 January 2021
At the beginning of January 2021, the renovation of the Church Office Building plaza was announced and has begun.
Temporary fencing is in place to block off the areas that will be under construction for the next year and a half.
The south side of the temple is now covered in scaffolding. This will help workers in the stone repair and cleaning process as well as improve access for materials into the temple.
The deep excavation on the north side of the temple continues. The efforts right now will prepare for the placement of a second crane on the Temple Square construction site.
