Day 30 or So-Lower concrete and Upper Framing

I am behind on postings due to preparations for our son's wedding this week. There will be no pictures for the next week, as framing is being done on the upper garage.
The lower garage had its 4 inch concrete floor poured this week. The 4 inches is so husband can have a "lift" to work on his cars. You can also see the framing for the floor of the upper garage.

The framing to support the upper garage is also completed. After plywood, concrete will be poured over this suspended floor.

The unexpected, expensive, retaining wall to keep the driveway and the people from falling from the upper driveway.

At the far right of the retaining wall will be a path down to the lower level stairs (another "work order") in order to allow access to this hill for landscaping purposes and to travel from the upper garage to the house if one doesn't want to go through the garage, through the man cave and out the lower stairs.
I asked husband, what is "this wall". He didn't tell me because it wasn't a "work order $$$". Apparently the concrete contractor kicked the wall at the right, and it collapsed and broke a piece off, probably because of an air pocket. So this new wall is a fix for the broken wall. Hmmm... I wonder how many other air pockets there are?

Until after the wedding....
