I had a version of this idea. If making multiple domes under 24 foot, the thought is to make up (or have a signmaker make up) a full sized floor template. I see it made out of a material that can be rolled up but not have too much elasticity. Perhaps airform material?
It would have every wall, door, plumbing, electrical, HVAC (if any), phone, CAT etc. color-coded and marked on it. Maybe even furniture.
On the first day it could be layed down on the dirt on a center pin through a metal grommet and be spun so the marked doors and windows to face the direction desired. Then after then after the ring and concrete floor is poured it is layed down again.
Transferring all the markings to the ground below would be done with more grommeted holes (plastic) at wall corners over the floor. Same with where E boxes and plumbing pipes come through. You would end up with Ray's method and the advantage is that with this and on subsequent domes it saves a lot of build talent layout time.
Probably not a good idea to leave it on the floor during construction though a builder could keep re-laying it down if you are going for a concrete floor. It would save marking up the surface.
As you can easily imagine, it's also a great visualization tool for a first time builder is looking at a dirt lot. Even if they don't yet have a lot they could set it up in their yard or nearby parking lot to "walk through". Every new home builder tries to imagine where everything is from wooden stakes in the ground. With these plans you can actually and accurately walk around "in" it.
This is whole new product line for Monolithic. Full sized templates are like a giant blueprint that you can stand on. Then when construction begins they are used to precisely lay out the structure. Monolithic could offer them with IO20s and send in advance of cabins for preparatory layout.
