Thanks!
There is a company in Independence, Mo. (Terradome) that had the forms and they formed, poured and waterproofed on contract. They did the structural engineering for the domes. After that I did most of it myself (with hired help on the concrete work). I did have a local plumber lay the sewer lines, gas lines and plumbing. Otherwise I was the architect, engineer, landscaper, carpenter, welder, electrician, stone mason, sheetrocker, painter, etc.. One of these years I will get the technique figured out to make large stained glass windows without breaking them while turning them over!
The year before the project started I dug a test pit about 10 feet deep and got a soil engineer to check it out to determine bearing capacity so we knew what was required for footings.
