Arcologies always seemed like a neat idea to me, but I've never seen an in-depth look at their proposed infrastructure.

What would power and communication distribution look like? HVAC? I assumed chill water with several distributed plants. This place is going to need lots of loading docks or it's own trainyard for food and other consumables. Domestic and waste water would probably both need to be handled on site.

I've never seen those aspects of an Arcology design explored.
