Rough staking changed, excavation incorrect

What surprises me is that none of those involved in the excavation could notice this "small" deviation of 5 meters!

I had the same thought. That is also being pursued in parallel.

Well, trying beats studying. It probably depends on the fine print.

I don't find it unusual that not everyone looks at it twice or thrice. Although usually the earthworkers also have a site plan and a 5m difference could already be noticeable.

The question is who moves the stakes (and it would have to be all of them, because otherwise it really would have been noticed if the area suddenly became much smaller). The only one who could actually have an interest in that is a neighbor. Does your planned building perhaps shade someone's terrace? Or maybe the village youth, as a joke.

That's crazy. I would also ask around in the neighborhood if anyone saw anything. If it was cordoned off, someone must have climbed over the barrier, something like that usually stands out in small communities.

Sure that everyone had the correct plans? And you have seen the surveyor's pictures?

We know a construction project where it was only noticed when the neighbor started, legal dispute has been going on for 5 years, house meanwhile torn down and rebuilt in the correct position, only who pays for it is not yet decided.

Or the excavator driver messed up and is now blaming it on shifted/moved posts.

Or the excavator operator messed up and is now blaming shifted/moved posts.

But the posts are really standing incorrectly, as far as I understood. Why should the excavator operator dig a hole 5 meters off and then move the posts afterwards?
