What's the minimum diameter circular slab I can use for a dome with no bays? In one place the schematics list the diameter as 88" & another as 92". I was told 90" would be enough but I'm worried that it might not be. My forms are being put in now, but I can still have them increase the size a bit if necessary.
Thanks
I heard back from Babak that the wall diameter is 88", but the dome diameter is 92" so I should be fine with a 90" diameter slab. 😀
