Received GU offer - Assessment of fair offer?

Less material used = cheaper offer..

On the other hand, there are high price increases for material that is becoming scarce and expensive everywhere. Have you signed yet?

You wrote about a 210 sqm / 650 k construction project. This is not a hobby homepage for which you search "Disclaimer Generator free". Rather, I consider it appropriate here to hire an independent architect. Then you don't compare general contractors based on their ready-made construction service description from a package, but work out your construction service description with your architect. You do the tendering actively.

Hi and why now? Will it be better with the architect as the manager of the individual trades? I don't see it as clearly as you do; I think both have their pros and cons...

In contrast, there are high price increases for materials, which are becoming scarce and expensive everywhere.

Have you already signed?

I have also noticed that material prices have been rising quite a bit in recent weeks..

No, we have not signed yet.. There is still a need for clarification, for example regarding a guarantee amounting to 15% that is to be deposited..

Will it be better with the architect as the leader of the individual trades? I don’t see it as clearly as you do; I think both have their advantages and disadvantages...

What is a "leader of the individual trades" and what do you mean by "both"?

What is a "Leiter der Einzelgewerke" and what do you mean by "both"?

Well, the construction manager who "manages" the house construction consisting of individual trades. By both, turnkey construction with a general contractor and individual contracts with an architect are meant.

A planning with a self-paid architect along with a tendering with individual lots does not at all exclude allowing general contractors (GU) to bid. But then the description of construction services still belongs to the part actively formulated in-house, and with the construction management by the self-paid planner, one also keeps this control during execution. The "construction manager" of the GU is only called the same but follows a completely different objective. So there are three and not only two ways, and in the mentioned size and budget league, the group of GU, draughtsman, and GU construction manager is no longer an appropriate choice.
