Which trades follow the shell construction?

However, before the electricians arrive, a screeder comes by to seal the floor

That is actually within the responsibility of the roofer.

Why do electricians and roofers seal floors? Or do you mean these bitumen welding membranes? The carpenters at our place welded them in very early, and one of them badly burned his hands and had to be taken to the hospital. Karsten

That is actually the responsibility of the roofer.

Really?

I haven't heard that the roofer lays the membranes on the ground-contacting floor..
Maybe only the sealing of the roof structure..

Why do electricians and roofers seal floors?

There was never any talk of electricians
With us, the screed layer does this.
But we could also do it ourselves. They are just self-adhesive membranes.


When does the exterior plaster actually get applied?
Is there a rule of thumb for that?
In the past, the house was “dried out” for 1 year..
But somehow we often see houses where the exterior plaster is applied directly after the shell construction (when the scaffolding is still up from roofing).

If you do the windows after the electrical work, you can in many areas then do the electrical work again after the windows... If you inform the plumbing after the screed, you can possibly also remove it again. Only electricians before plastering can probably be considered generally valid. Tips are given here without knowing the planning, that doesn't work.

First of all, the thing with the electrician who seals the floors was clearly sloppy reading. On my part. The exterior plaster was applied for us just after the topping-out ceremony. The colored plaster a week ago. With Ytong, there is practically no moisture in the stone because it is glued, not mortared. The wind, the sun, the house was dust dry on the outside. By the way, one of the heating engineers put that foil and the insulation mats underneath on the bitumen welding membrane, then laid his coils on top of that. Karsten

Really?

I haven't heard yet that the roofer lays the membranes on the ground-contacting floor..

So I am talking about the sealing of the base plate against vapor diffusion and ground moisture, commonly this is a "torch-on membrane," i.e., bitumen. Yes, that is actually a roofer's trade.

Topic windows:

Although we certainly are not building in a crime hotspot, no electrician or plumbing company will start their work here before the windows are installed.
