Hi Balduin, Frank is unfortunately completely right. The construction manager works for his client, not for you. Even if you were perhaps told differently at the beginning. Your contract probably states: House X at price Y at time Z. That’s it. Interim deadlines are deliberately avoided, as are specific intermediate dates or a construction performance description that goes too much into detail. It can still all go well, you can also find examples here in the forum, but it doesn’t have to. That’s exactly why my advice is to pay for an expert yourself. They really work for you. Not because they are a do-gooder, but because you pay them. At least what this person documents during the construction phase will be better recognized later in disputes than your own records, photos, etc. You might even congratulate yourself later for this decision. It makes the construction 1 or 1.5% more expensive for you, but that’s not the end of the world. The matter with the Schlussrate then turned out in court as one usually knows: They somehow reached a settlement. The general contractor effectively got 5 grand less than he would have liked. But that doesn’t cover our frustrations in between nor the legal fees. For us, that didn’t matter, kind of like: For all the crap in between, the general contractor (owner = managing director) at least gets a little financially held accountable. 1 fewer trip to the Maldives for Monsieur and Madame. That’s how it was, and that’s fine for us. No more desire. For you, as I said: Good luck and keep your nerves!! You’ll manage it.
