Hello again,
somehow the base slab just won't let us rest. The builder doesn't seem willing to confirm that the load with the truck was harmless for the concrete. Unfortunately, our building expert has left us somewhat in the lurch here. I don't have more than one report on this.
(We have similar crap now with the ceiling as well. Poured at 3 p.m., the bricks were placed on it at 7 a.m. the next day (luckily no truck could drive on there!). Our building expert even witnessed this)
Nevertheless, since we are not getting a confirmation from the builder and meanwhile the roof structure is already up because everything is happening so quickly, we are considering having an expert report made for the base slab. Can someone with experience say something about the costs for that? I would set a deadline for the builder to respond, and if he does not react by then, have the report made at his expense or withhold the costs from the final payment.
The only question is whether I am allowed to do that.
