Once you've constructed the mold, the real trick is filling it evenly throughout. If the top is too thin, you have a problem. Also, you need to fill it in with rebar in place, which makes it twice as complicated.

if they're one foot thick thats excessive, i'd say 6-9 inches, but with steel bars inside the concrete
its called reinfoced concrete lol.

on that note...
2300 kg/m3 is the average density of concrete
16 ft3 = 0.45307m3
and a mass of:
1042.061 kg = 2297.351254lbs
have fun lifting that...
now if it were 2*2*1
it would weigh around 575 lbs, which three or four men could lift

rebar goes through the holes in cinderblocks, and sand is poured in around it, and then you've got solid material. cinderblocks can be broken kind of easy, but its a good idea, that i support

....Domed concrete, with a central flared column for support (possibly not needed?)

Carefully, on piece at a time, with a lot of planning beforehand.  Lots and lots of planning and design.

Dig out a rough torus, centered on the center column, with the walls the final height you want them to be, plus a bit (for the ceiling to attach to/rest on).  Then, build up the center column, slowly raising the ceiling as you go.  Finally, when most of the center column is concreted, bricked, etc, finish off the roof by building small but wide curved strips of concrete that can be layered all around the torus to decrease the water leakage.

By using this design, you use the earth itself as a support column, rather than building a roof and then building a support column.

Of course, I have no idea if this will work, especially with many feet of soil on top.  Currently it's all in the "intellectual thought experiment" stage.  But I think it would.
