Gravel and ductwork

They delivered a lot of gravel today. They filled in the garage on the right with gravel. I was hoping one of our cars would be the first one to be parked in our new garage. Maybe the Bobcat doesn't count as a car.
They put blue chalk lines in the garages and area in between the garages to show the new floor level. The garage on the right was filled with gravel almost to that level.
The also started putting our heating ducts back in. We had flexible heating ducts hanging below the floor joists before. We need to have some solid heating ducts because of the garage doors. They are removing some of the floor insulation and putting some heating ducts between the floor joists.
We are still using flexible ducts. And they are putting the flexible ducts between the floor joist in some places. I thing running the heating next to the floor will be a good thing.
In addition to doing the gravel and ductwork, they also framed some doorways and added plywood in places.
