I'll try to knock off a few at once;
I doubt they could find cranes big enough to economically add another floor. Land is cheap, they'll build outwards.
Concrete is sometimes mixed on site, but I would doubt that to be the case here, you'd see a Batch Plant and some Sizable Aggregate piles and given that it's Nevada, probably a facility that can hold/produce ice or Liquid Nitrogen. Local concrete companies do this very efficiently, and besides there's very little concrete work left to do. This is a structural steel building, not precast. All the concrete is under the steel and buried in sand.
Cladding will come in later, it'll probably be thin gauge steel. Not sure what sort of insulation they'll need. No harm for that steel to sit exposed for a long time. Nevada's is nowhere near and ocean and the relative moisture in the air is low. why do you think they store old planes in the desert? Low moisture.
What is a bit puzzling is that their appears to be very little activity on site. I don't see any sort of HVAC/Utilities (Aside from a few sections of pipe) or other Mechanical systems being installed. I would have expected all sorts of things sitting around, especially some of the larger components that can only be installed while everything is open. It all just looks very... quiet and more like a warehouse than a factory at this point.
Since the steel required to support the extremely heavy equipment is already so large, the added height and weight would require larger cranes and more critical picks. larger cranes, with more line parts (more pulleys) are also slower, and more expensive to operate.
