ᐅ Which trades come after the shell construction?

However, before the electrical work, our screed layers come shortly to seal the floor.

Actually, that is usually the responsibility of the roofer.

Why do electricians and roofers seal floors? Or do you mean this bitumen waterproofing membrane? Our carpenters installed it by welding it in very early, and one of them badly burned his fingers and had to be taken to the hospital. Karsten

Really?

I haven’t heard of roofers installing membranes on floors that are in contact with the ground...
Maybe only the sealing of the roof structure.

Electricians were never mentioned.
In our case, the screed installer handles this.
But we could also do it ourselves. They’re just self-adhesive membranes.

When is the exterior rendering usually done?
Is there a general rule of thumb?
In the past, houses were left to “dry out” for about a year.
But nowadays, we often see houses where the exterior rendering is applied immediately after the shell construction is finished (while the scaffolding for roof work is still in place).

If you install the windows before the electrical work, in many cases the electrical installation will have to be redone afterwards.
If you inform the plumber after the screed has been laid, it might be possible to redo that as well.
Only having the electrician complete their work before plastering can generally be considered good practice.
Here, tips are given without knowing the full plan, but that approach does not work.

First of all, the comment about the electrician sealing the floors was clearly a careless misreading on my part.

The exterior plaster was applied just after the topping-out ceremony. The colored plaster went on about a week ago. With Ytong blocks, there is practically no moisture in the material because they are glued instead of mortared. The wind and sun had thoroughly dried the exterior. By the way, one of the heating installers placed the vapor barrier and the insulation mats underneath the bitumen membrane, then laid out his piping on top of it. Karsten

I haven’t heard of roofers installing membranes on the ground-contact floor slab..

I’m referring to waterproofing the slab against vapor diffusion and ground moisture, which is commonly a bitumen-based “torch-on membrane.” Yes, this is typically the work of a roofer.

Regarding windows:

Even though we are certainly not building in a high-crime area, no electrician or plumber will start work before the windows are installed.
