Sounds like a depressing place to live with no windows. Maybe they don't have egress requirements there?

When it collapses, at least they won't have to worry about burying the bodies.

Ventilation?
Natural light?
Escape paths in case of fire/ other emergency? (Climbing DOWN 65 storeys will take half an hour. Climbing UP the same height will kill you!)
Should you do something just because you can?
Too many questions. No good answers.

RE: Earth-scraper in Mexico
The answers ARE different for tunnels because:
1. The tunnel itself may (hopefully, unless blocked with rubble or water) provide an escape path at least in one direction. The same goes for ventilation
2. No sewage needs to be drained from a tunnel.
3. Natural light is not required in a tunnel because you don't expect to spend more than a few minutes in it.
4. Finally, the number of people who may be affected by a tunnel fire or collapse is far less than the number of people who can be affected by such an accident in a building.
RE: Earth-scraper in Mexico
1. well not really, if there is a problem I would be taking the escape hatch rather than driving the possible 11km of the Laerdal or longer.
2. there normally are one or two toilets that get pumped to the surface.
3. 24km long could take a while to get thru.
4. Take all depends on the type of event.
I am not saying this is the best idea in the world, but I have seen worse.

I honestly have no idea how they'll figure out the wind coefficients.
And shoring as they build from ground level downwards will be a nightmare.

If the soil is around 120pcf the earth pressure will be around 46 bar at the lowest point. Perhaps they can pressurize the lower levels to balance this.
Also the architect is showing an inverted pyramid. Wouldn't it make more sense to make this a cone shape? (compression rings)
RE: Earth-scraper in Mexico
RE: Earth-scraper in Mexico
Of course an architect designed it ... would an engineer?
It is a sci-fi dream to build something like that. The practical problems of excavation and shoring during construction will pursuade them to do something else.
Holding back the load after it is built shouldn't be a problem. simple concrete rings should give you all the soil resistance you need.
I am sure there are basic problems with getting the waste out of the hole each day that will cost unnecessary power and I doubt the grass they would get on any of the ledges along the inside courtyard would last and you'll have mud banks to enjoy.
The downsides just keep popping up.
I actually wonder if this is a satire on the new city zoning laws that prohibit tall buildings.
RE: Earth-scraper in Mexico
In Mexico city an expert in subsurface drainage will obviously be required.
A geo-tech engineer looks at the options for soil loadings since there will be many options when the site is bored and then opened.
The architect is responsible for the general concept and everything that affects the appearance and use. This also includes the general mechanicals and the and the number of toilets. - There are specialists in that field.
I am a registered engineer, but I also am an amateur "Crapologist" in honor of Sir Crapper that developed the first usable flushing toilet. In spite of documenting toilets in 40 countries, I would not venture outside my professional field to determine the number of toilets and sanitary removal system. If built, I am sure there will be a few $6000-$7000 Toto toilets somewhere.
If it is built, I would love go to see the finished product.
In Dubai, many of the structures were also considered follies, but the professions worked to make the concepts work.

By follies, I was referring to initial economic development without recognizing the engineering.
I stayed at the "7 star" hotel, but had to share a room with a friend from Kuwait that got us in. Fortunately, I was his guest and his firm picked up the $2500 room..
I was at the 3/4 point of the construction of the tower and there were engineers everywhere and fortunately most spoke English/British but was very professional to get the high strength concrete up that high on a 24/7 project.
