My first "Real" Factory

4 floors: 1. Smelters, 2. Constructors, 3. Assemblers (for reinforced iron plates and rotors). 4. Assemblers (Smart Plating at 4/m)

I need any constructive criticism, opinions, tips, tricks, all the marbles. Apart from the obvious: it's big, it looks like it was made by a 5 year old, etc. I've been playing the game for like 40 hours, and this is where I've gotten so far, I've done like 4 major restructuring of my factories, and I've got enough usable material for the phase I'm on, so I've decided to exclusively focus on making the Project Assembly parts; with this factory being the first of 3 for Phase 2.
