Hi I have a few suggestions.
Recycling: The recycling of unnecessary things in production, or at least shredder.
Repair of destroyed things (wheels for cars, doors and other parts).
Connection: oxygen and etc. to the base must be using a hose (like cables on electricity).
it would be better to add a lift (in building up), ladder (easy to get to the roof) or track.
shelter against radiation, or prevention or decontamination room
