Construction progress: Duplex with WU basement and developed attic

That is all correct and I also know that things can go wrong. But I calculate high chances for myself. The [GU] presents himself as a construction manager but is actually a butcher. Three expert opinions unanimously state that none of his work is in order. Another one will follow, which will determine the value of his work. The construction manager who did not recognize the grossest mistake and stopped appearing despite an ongoing contract and multiple requests. A lawyer who issued an extraordinary termination without the previously required warning of it. And in addition, a really good lawyer who is active in the industrial and large construction site sector.

: Thank you for your post, which I really like. I fully accept your attitude. Everyone has to decide for themselves how to deal with such things. I am completely different in that respect. I could never submit to something or accept something without a fight that I perceive as unjust. I would break because of that.

That’s how it is... everyone decides for themselves and there is no universal solution. However, one should never forget to look at the other side; right now, I am also looking at the other side.
But if you generally never want to submit or accept anything, the likelihood of future events will sooner or later painfully force you to do so. I would want to practice that a bit beforehand :D... the "radical acceptance" of realities, which is difficult for all of us.
Anyway, one rather "breaks" because of interpersonal things like children, people, etc., and not due to a lost legal process.
How you describe yourself—"never... breaking... being right... fighting... etc."—surely you bear a significant share (not fault) of your misery. We are currently in another dilemma ourselves and we have also contributed to it being the way it is.
I read here that someone (you) fights, bites, pulls (perhaps being "right") but at the same time is standing in the boxing ring... so the question arises whether you will eventually break in the self-chosen (because you are right) boxing ring or afterwards on the sofa with a drink, having left the ring.
It will not happen, even if you might wish it were to happen, that you eventually stand there satisfied after having won all those victories in court... that does not happen.
I do not want to preach to you, because I have often not found the right path for myself, but what I read from you, especially the HOW, indicates that the house build is only the first round in the ring... life can be so beautiful!

If I tell you now that his hourly rate is 300 €, you will probably be annoyed about your career choice ;).

No no, don’t worry. My career choice was definitely right. Rather than struggling as a lawyer for 300€/h, I play the Advocatus Diaboli for 0€. Not to annoy you, but to provide some ideas about where this could be going. If you can refute my concerns, then you are on a good path.

But I calculate high chances. The general contractor (GU) presents himself as a site manager and in reality is a butcher.

Training as a butcher doesn’t matter; he can hire subcontractors as he pleases. The site manager is the one stated on the building permit. A site manager must have expertise and experience. But since these two points are, as far as I know, not further specified, it’s all very vague and the outcome uncertain. With bad luck, some foreign expert site manager will be pulled out of the hat during the process, who cannot be held accountable. An opposing lawyer could definitely pull something off there.

3 expert reports unanimously state that none of his work is in order.

Yeah, then he initially has the right to fix it. But we have discussed that at length already. It gets tricky where you worked around the general contractor and parallel commissions took place. Let your expensive expert unravel that properly, otherwise it could backfire on you :(

The site manager, who didn’t recognize the grossest mistakes and, despite an ongoing contract and multiple requests, simply stopped showing up.

If the contract with the site manager does not stipulate penalties, this will just fizzle out. I don’t think anything can be gained here. The hours worked have to be paid. I’m afraid the site manager can only be held accountable if he documented in writing that the trades were in order. For unnoticed mistakes, it looks bleak.

A lawyer who declared an extraordinary termination without the prior necessary warning of this.

That is possible for an important reason. If continuing is unreasonable, then termination without notice occurs. I think the lawyer will be able to justify this. The question is what damage might have arisen from this. And the question is what this means for the general contractor, to whom you denied the opportunity to fix defects.

And a really good lawyer who is active in the industrial and large construction site sector.

I hope his knowledge is transferable to a private small construction site. Enough playing the villain, I actually want everything to end positively :)

suggests that building a house is only the 1st round in the ring.......yet life can be so beautiful!

No, it is by no means the 1st round in the ring. As ypg described me, I am such a nasty broom, make life hard for my fellow human beings, am incorrigible, and fight my way through life, "no matter what the cost."

No, it is by no means the 1st round in the ring. As ypg described me, I am indeed such a nasty broom, making life hard for my fellow human beings, incorrigible, and fighting my way through life, "whatever it takes."

I didn't mean the "fighting, tugging, etc." as an accusation, since I don't know that. My approach would rather be that building this house was extremely nerve-wracking for whatever reason, and one would like to get out of this "ring" back into a calmer life as soon as possible instead of going through various legal instances. So it was more a suggestion FOR you and thoughts about seeking a possibly calmer path FOR YOU.

That has already been discussed multiple times :) I probably wouldn’t have the nerves for it myself either, but deep down I find it good when someone stands up for their rights. , I definitely wish you continued good progress with the construction itself. It seems like something is moving there.
