Hello Passiv.H.N.
I had the ventilation planned and then installed all 11 decentralized fans. Drilled core holes, insulated the plastic sleeves beforehand, and inserted them into the wall. The fans go in there. Mount the cover on the outside, attach the wiring inside, and snap on the inner cover. You can also insert a pipe through the wall, seal it, and then pour the concrete.
It’s a lot of work and you constantly learn more.
As Daany already said, a lot of planning and experience are necessary. My statics were terrible. Fortunately, I could talk to the guy and had hooks made from the baskets. That made it easier. In return, I had to tie all the parts together. If you want to build with these systems and realize everything yourself as much as possible, you really need to find out if the huge window works easily with the system. Everything is doable. But whether I snap in a ridiculous 4x12 rebar in 5 minutes standard at euromac2 or have to thread 4x16 iron bars in the tightest space and spend hours on it.
For me, the braces held, and I have already reinforced some corners on purpose. My garage was poured in one piece. Highest point 6.4m. Nothing flew away.
Elsewhere, I had two breakouts and the concrete was set too thin. The experienced concrete pump guy said it was good according to his experience. But he usually pumps all around and then only 50cm, not like at euromac2, 3m in one go.
I’m looking forward to hotzege (maybe) building with euromac2 and maybe being allowed to stack a few stones again (if I’m allowed to come). That definitely goes faster and easier than carrying regular stones.
One should not forget one thing. This is house building and a ton of work. Normally, there are professionals who make the masons look old with such a system and enjoy the evenings without having moved two tons of stones. My neighbors had the shell structure up within two weeks... including the slab. They would still have to assemble the stones from front and rear parts. The alignment supports were fixed with wire... and they also pour up to three meters in one go.
That would be it for now...
Have fun planning
