Prefabricated house / Shell house

What's going on here, why are more and more people being attacked for not letting the general contractor do everything? I do find two days for 3 people quite ambitious for a rough-in installation. But I think it's doable for a professional. As a trained electrician, I only need 4-5 hours per room in our old building to complete the electrical work. That means creating cable routes, installing boxes, and fixing everything in place. And I haven't pulled wires in 7 years.

And a composite pipe can be laid almost even faster. Especially in new construction, it's much easier because everything is open.

Own work was rough installation of electrical, heating, sanitary, rest general contractor

each two days with three people

so 3 times 2 days

You already listed it yourself. The approach via labor performance For me, with rough installation, it's zero.

That doesn't work, because the material isn't free of charge. Zero -> so no payment to BG-Bau? No consideration from you to the people who help you? Regarding the electrical work, I can only say that in our new build, 2 people were employed over 5 days. But as I already emphasized, that's the difference between

holding back on everything limiting yourself to what is feasible

and yet more than a minimum equipment. @Nelly: And what did you do in those 4-5 hours per room? By the way, if I quickly count my rooms in the house, there are 16 (I'll count the hallway too, since switches, sockets, lamps, etc. will also be installed there), times 4 is 64 hours. Divided by 3 people, that's 21.3 hours. So really quite ambitious for two days.

The time was allocated for a bedroom with a separate dressing room. This means 2 light switches, 16 sockets, Sat and 2 network cables. So in my eyes, no "savings" electrical installation was used there. One must also always keep in mind that with a company you also pay for many administrative things, e.g. creating offers, sales...

But did the time also include pulling cables to the utility room (in my case, in the basement), wall and ceiling breakouts, connection to the fuse box or was that rather "only" in the room? With a company in a new building, for example, you also pay a security deposit (warranty) and possibly insurance coverage in case of errors. Of course.

The cables have gone to the sub-distribution. Well, it is about a rough installation. There is no electrical box installed yet. So I did not take that into account.
