DEKRA scales the prices according to living space, and for our 255m², it's €855 gross per appointment and €565 for the foundation slab; with 8 to 10 appointments, that really adds up!
With us, I believe it is about 700 per appointment. We have 197 sqm of living space and no basement. It is, I think, somewhat more precisely 4300 euros.
And already paid for noticing three improperly installed patio doors.
I'm not complaining about the price at all. We are very glad that we chose construction supervision and are very satisfied with the expert's work. It is definitely worth it for us – even if nothing were to go wrong during the construction. The assurance that a knowledgeable external person is overseeing it is worth the money to us.
Let's continue. Only the window that didn't fit has not yet been replaced and no adjustments have been made yet. But that would probably be asking too much at such short notice
I pay 85 euros net per hour. No matter what he does for us. ( alles was mit uns zu tun hat auch außerhalb der Baustelle ) I find scaling according to sqm cheeky.
