Check out this web site http://www.tridipanel.com/
We have been calling it 3D but really it is called Tri D
Here is how it goes. You pour the slab and footings. Re-bar is embedded in the footings where walls will be that sticks up a few feet. Then the tri-d
panels are sort of impaled over the re-bar to secure it to the floor. The whole house is built by wiring together the panels, cutting holes for doors
and windows, and running plumbing and electrical through the walls where the insulation has been cut or melted away etc. Once it is all put together
it is strong enough that you can walk around on the roof.
Then they either throw concrete on it or shoot it on with a pump like they do swimming pools. Goes up fast. Makes for a great house. We are sure happy
with ours.

roof forming
That is different than the link that I found. The system seems similar. How do you form for the roof? Same as poured slab in block construction? If
two story is a requirement, what carries the second floor slab?
From what I can see, these are foam core wire panels designed to be shot with gunite and trowel finished to specifications. How many unite contractors
are there in this area? For that matter, how many small steel fabricators are there? In my area, there are a lot of small welding/steel fab guys who
are good and not trying to make a killing on any single job which is why, so far, steel looks the best although soft wood lumber prices are coming
down.

The Tri-D panel is strong enough to carry some pretty large spans without a beam, if a beam is needed,
it is poured in place at the same time as the floor. The panels are wired together and a steel fabricator is not necessary to erect the panels. There
is a special tool available that applies wire clips to join the panels. There are only a handful of contractors that have the pump to shoot the walls.
Some guys will just plaster by hand, but it is inferior. I would never consider a house built of softwood because of termites and powder post beetles.

Actually, that would be the construction method for a roof, for an intermediate floor, they would normally
be a solid pour or a casaton grid pour, but could be tri-d panel construction.

The entire roof of my house was done with tri-d panel as well. There are some large poured in place beams that cross the ceiling of the great room.
When it was all wired up together you could walk around on the roof panels before the pour. Pretty sturdy stuff.
Paula thought the window in one bathroom was going to be too small before they shot on the concrete. Our contractor said "Hey Juan!" and had Juan clip
the wire and cut the foam to make the window opening bigger as we stood there watching. "How's that?" Pretty cool we thought.

We did a combination of post and beam with infilled panels and standalone panel and roof.
The slab has been drilled for rebar to locate the panels
You can see the poured posts and the rebar locating the panels
Reinforcing bits for corners, openings and flats. You can see the thicker panel used for exterior walls and roof and thinner interior partition walls
Rough openings for windows and doors. You can see wood bucks for attaching windows and doors. Rebar for roof to wall and panel to panel structure.
Flat mesh at 45deg for corner stress relief. This section we used panel for the roof.
Wiring and liquid lines for AC
Classic caseton roof inside the post and beam area. You can see the transition to the panel roof. Poured out, the roof deck is 1 flat surface.
Inside caseton roof. You can see a bit of panel to post infill on the left.
We did all the mudwork by hand. My contractor was not comfortable with the truck/spray mix or the operators skills. Took a long, long, time but -
It looks great
Just about done. Needs Teja roof and a good clean up.
Upstairs deck with Sea of Cortez view. This was the only bit damaged in Odile. It was knocked over in the direction we are looking. My fault for
approving the spindly single post supports. They are now 3 on a corner lag bolted and metal strapped together and I can now cross brace the entire
roof with cargo straps.
The number of $140/sqft was right on for my project and that includes windows, AC, doors and kitchen bits from the US
