Cradle to grave comes to mind. Would it feature decentralized hospitals such that you can get all the different kinds of care you need in your room. Would workers who keep the place clean, etc., live in the same areas as the ultra wealthy or would there be designated areas. Would all groups truly mix. There has to be service tunnels, would there also be separate tunnels for separate groups. Or could the top level be totally off limits to anyone without a gold key.
Building it long along the ground, open sided on tp instead of tall, makes some problems like getting around, fires or massive water leaks much more practical to handle.
I wonder if the sanitation, fire, water and power, local environment departments would be decentralized or in one massive section, perhaps that stuff is located below ground level.
It looks like it is open to the air on top, I guess that would mean an extremely powerful air flow to keep it cool. The top has to close, there has to be times when weather disturbances, especially the bigger events now common today, could not be handled with the roof open.
In super enclosed area like that, people would have to stay in good health, perhaps receiving constant monitoring, in order to keep the incidence of infectious disease to an absolute minimum.
Is there any manufacturing work located in there or is someone else suppose to do that somewhere else. If everything is imported, the ports whatever they are, would be very busy places. Does stuff just drive in anywhere or would there be large receiving ports situated throughout the length of the building.
If they want to get this built tomorrow, I suspect the power needed to run that place would be nuclear. Nuclear supporters have been building support for nuclear as a green power source.
To have everything used inside the building easily recyclable, it would have to be specially packaged. Could that be done inside to raw materials taken in, or would that have to be done outside the building. No menial work inside or would there be a large group of support workers to make the place actually work. Robotic services might be envisioned but that won't be a viable option for a long time.
This could could take a long time to just create the foundation and basic support structure, something to keep people busy while other people try to figure out what to do next.
