Is the construction performance description detailed enough?

Now the general contractor had previously told us about the extra costs, he estimated the civil engineering well, almost accurate, drainage etc. was a fixed price offer from him, samples were rather sparse with him, I think he didn’t really want to because it disrupts the construction process when the client wants so many extras, there were five interior windowsills, take one of them, there were two exterior ones, this one or that one, there were three window handles, the expensive one with the keys is nonsense, you lose them anyway, there were three roof tiles, take red, brown, anthracite, end etc. He sent the tiles to Harry’s tile market in Lübeck, pick something out there, up to 25 net I’ll cover it, above that it’s your pleasure... thus the sampling was an inexpensive matter. Some clients here would have been desperate with him because he doesn’t like to part with his money. Karsten

It will simply happen... whether during the civil engineering work, the drainage, or the patterning center

And in the process, you usually also gain a feeling for how fair the general contractor is with additional costs. That was worth even more to us than the specific items.

With the site work, the "leverage" of costs is much more significant than with laminates and mixers; you really can’t emphasize that enough to clients. And who pays which incidental costs. Matching the Dachstein tile tone-on-tone to the window frames never succeeds perfectly anyway, RAL or not.

I completely agree with you. That sometimes escapes us flatlanders when here the total costs for earthworks were below the price of a mixing valve…
