My husband and I lived in Provo for a few years while attending Brigham Young University, where we met and married. We attended church a few times in the Provo Tabernacle, when there was Stake conference held on the site. It was a lovely building, rich in the history that we share as Mormon Pioneers. With that in mind, we were happy to hear that the Church would rebuild the tabernacle and redesign it into a Temple.
Since then, each time we visit Provo to see our children attending Brigham Young University, we drove past the site to see how construction was coming along. Last weekend, we did the same and found it covered in scaffolding, but looking as if it was nearing completion.
We were in Provo to participate in the graduation ceremonies of our son, who was graduating from the School of Engineering. Convocation gave us a real treat, as the main speaker was
Doug Welling, the Chief Executive Officer of Jacobsen
Construction, the firm responsible for the renovation. Welling spoke about how important it was for them to build a
solid foundation under the tabernacle before they could make it into a
temple. It was fascinating to me!
Since the tabernacle was
completed in 1898, regulations have been put into place to protect buildings
against earthquakes and other problems.
To build the temple there, the building needed to be brought up to those
standards. And they wanted to do it
without injuring the old building in the process.
Since the building is all brick with thick walls, it weighs
a lot—some estimate it weighs 6.8 million pounds! So you can’t just pick it up and move it,
pour cement under it, then move it back.
They had to support it first, then dig all the dirt out underneath it, then
pour the cement under it. Additionally,
plans were to expand the building downward to include two basement floors.
Jacobsen construction worked with several Engineering firms
to figure out how to do it. First they
stabilized the outer brick walls and tied them all to each other. Then they drove about 150 thick metal rods
into the ground 90 feet down around and under the temple. They could do that from inside the walls,
since the floor and roof were destroyed in the fire. Welding all of these rods to horizontal
rods, they created a platform that would hold the temple up. Then they welded the supports holding the
walls up to the platform, basically transferring the weight of the temple onto
the 150 rods. Now that it was supported,
they could start digging. They dug 20
feet down, exposing the rods, and welding cross beams to give more support and
stability to the building. They put up a
wall around the outside to hold back the dirt from around the temple. Then they dug another 25 feet down and welded
those rods to more support beams. The
tabernacle was now up on stilts! Now they could put a strong foundation
underneath.
At the bottom, they placed 400 smaller rods into the ground,
laid a grid on top of it and welded it all together. Into that grid they poured 18 inches of
cement, a nice firm foundation for a temple. Two-foot thick walls were poured upward until
they reached the bottom of the brick walls.
When the temple was resting firmly on those walls, the ‘stilts’ were
removed. Although it was a lot of work, the
tabernacle can now be made into a temple because of the firm foundation
underneath it!

make a movie of the temple being built!
Now that you understand what went into laying the groundwork
for this temple, you can appreciate what Welling said about
foundations. (This isn’t word for word,
just what I’m piecing together from my notes, but you get the idea.) “If you have a strong foundation, you can be
ready to do anything. The best is yet to
come. Prepare yourself for it by
building a solid foundation based on a testimony of the gospel, a good
education and a habit of service.” This
is good advice to a graduating class of engineers.
This is also great advice for all of us. A strong foundation based on faith in the Savior will prepare us for all of the great opportunities awaiting us. We add strength when we take time each day to read the holy scriptures and commune with Heavenly Father. Pondering is like boring deeply into the earth, reinforcing our base and anchoring ourselves to the bedrock of the Gospel of Jesus Christ.
As Jesus taught in his parable of the wise man and the foolish man, we must bore deeply into the rock so as to withstand the trials and problems that will happen to us.
Matthew 17: 24
Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:
25 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
26 And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:
27 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it.
