The Dirt Stops Here!

Do you see what I see?  Boy, was I surprised when I got to the site this morning.  It was 7:30, and yet there was a new slab!
My last visit to the site was Friday afternoon -- so this was a weekend job.  The lights were just coming down.
The mystery of the cardboard holes is solved.  They are place-holders in the slab.
I learned quite a bit this morning.  A lot was going on and I heard some conversations that were very interesting. For example, there are about 400 of those holes in the slab.
The slab is not intended to be permanent.  Its purpose is to sustain the weight of drilling machines.
The machines will place more metal casings, although not as wide in diameter as these piers.  The new piers, which are indeed called micropiles, will go down 40 feet, and then they will be filled.
This was the weekend headquarters, I presume.
I tried to observe and learn as much as I could.  The white pod belongs to Nicholson, the contractors from the north lot.
My handy-dandy camera confirmed that. 
Mr. Track Hoe was altering the south entrance to make access easier for the machines to gain entry for the next phase of foundation work.
Because for sure they can't use the north entrance.
Jacobsen has created a nice watching spot along University Avenue.  Oh, I love to watch!  It's even protected from traffic.  If you go, I recommend you park along Center Street, and maybe eat lunch at Los Hermanos afterward.
Removing the grout pools was a priority today.  Notice the huge crane parked in the middle of University Avenue.  You can see the gap in the green screen at street level for onlookers.
I am in awe of the men who drive these things.  These two trucks backed onto the site with ease.  And of course, the sky was clear in north Provo, but not where I was.
The red rocket is not needed for the time being and is being moved to the south lot.
Mr. Grout Machine, who has been so busy for the last month, was also tucked away, his work completed.   That job was not insignificant.  Although the grout barrier cannot be seen, it will protect the temple from any ground water.  Workmen with specialized expertise came from all over the nation.
I was delighted to see a tip of the grout wall, which you can see in the center front of this photo.  I have watched so many track hoes move so much dirt from this lot -- I can't wait to see it nice and smooth.
I was hoping to catch the sun rise from behind the tabernacle, but downtown Provo was covered with clouds.  I was surprised that a workman showed concern for my safety as I snapped this picture.  What could the matter be?
While I was in the garage, this guy had shown up.  I think this means I have taken my last photo from the NuSkin parking garage.  There is no need to worry about where the NuSkin employees parked.
Apparently their new garage is open and ready for business, although clearly not completed.

It's incredible the care that is going into perserving the old tabernacle. It would have been so much easier to knock it down and start over. It's truly going to be a treasure when it's finished. I hope my next son gets married there!

These micropiles look like they will be positioned directly under the shell of the temple (as opposed to the current piers which are ~3 feet to either side). I imagine that the foundation will be formed over the micropiles. From what I've read, the slurry retaining walls and the micropiles mean that the water table is probably fairly high and these would be precautions to stabilize the foundation from shifting soil (and sinkholes). I still think the existing piers will be removed once the foundation is complete. The manner in which they are attached to the steel beams supporting the shell looks very temporary. The examples I've found online of the pier method all have concrete and rebar joining the foundation of the structure and the piers in a solid mass, not a few bolts securing a steel beam which isn't actually attached to the structure.

When you say that drilling machines are going down 40 feet, is this "another" 40 feet below the already dug out basement?

Yes -- that's what's happening.
