Re: [papercreters] Re: Looking for a new place to call home.



I don't want to rain on your parade, but unless the inspectors in your area are really stupid or incompetent, this will not fly. Once you submit your engineered drawing, they will make sure the project is done exactly according to the approved plans. Especially with an unusual building like a monolithic dome there will be a lot of attention from the building department. If you start deviating from the plan you will be shut down quickly. What has to comply with the code is the final building. The plan is just your proposed method of reaching that compliance. They will be inspecting the building for final approval and issuance of a certificate of occupancy, and they will be looking at your original plans as they do that. This will not be the only time they will look at your job, several inspections are done during progress so the inspectors can see things that will later be covered up.

Finding an engineer that will sign off on major changes to a plan will cost as much or more than it would have to hire the engineer in the first place to design what you want. Good luck finding one who will approve shotcrete on burlap. Another problem might be shooting right through the burlap. All the guns I've seen have a lot of power to throw concrete several feet and when it hits, it hits hard. You need to be shooting onto a strong surface. Wire mesh on rebar would work, burlap might not.

Papercrete between two layers of concrete is asking for trouble. It won't breath, will have no way to dry, and will probably mold. It will remain damp and not provide much insulation value.

So, IMHO, it's a lead balloon.

  Their's a lot of people that are fighting building codes. I have an idea on how to get around it. I'm looking for input on whether or not the idea will fly.   Purchase a Engineered drawing of your choosing from Monolithic Domes.  This should satisfy the code requirements. Pore a slab with all the plumbing, electrical, and heating in it. Use re-bar to build the dome around the doors, windows, and chimneys and stacks. Cover it with burlap. Use a air compressor and thrash pump to shot crete the whole thing. Maybe 2 feet at a time allowing it to dry to add strength. Now get someone to spray one or two inches of polyurethane on top of that. Then 10 inches of papercrete on top of that. Then shot crete the outside.    You might be able to get an Engineer to stamp this variance. If not just shut up about it and maybe leave the polyurethane out as well. I will not be responsible for any of the out comes.
