The grand, expansive entry of the center "Spaceship" Ring in Apple's Campus 2 mega-project has reached its ceiling, with a steel structure now only barely visible over the construction barrier from the street, but clearly discernible from the air.
In the video below we can also see concrete void slabs that are being used to build an interlocking foundation and wall structure. Apple says that they "serve as both the ceiling of one floor and support for the raised surface of the floor above."
