Piercing in Halox cans - Who is liable for that?

I don't understand why you are defending the electrician. The general contractor always allowed some time. It's typical again that such situations arise when services are removed.

So when I read that, I wonder how flexible your electrician is. After the notification, another week of delay. So he didn’t find a single hour all week to nail the cables in there and insists on an approval. Are you serious??

I totally agree..

You yourself write:
“Otherwise, the general contractor could have reacted and informed within the last 10 days that such an approval might not be granted. Very annoying.“

In the last 11 days, the electrician could have found half a day to pull in the empty conduits.
If that doesn’t work, then probably even more won’t work out timewise with the electrician.

Why is only the electrician being blamed here? Regardless of whether such an approval is necessary or exaggerated, the GU and electrician had discussed everything in time, and the GU did not find a few minutes (not half a day) to clarify the agreed formality. That would annoy me here as well. If the GU has a problem with the approval, they could have raised it 11 days ago and alternatives would have to be found.

I see it the same way..

If that doesn’t work, then probably even more scheduling won’t work with the electrician.

It just depends on when the precast concrete slab was put in place. For us, the process was: precast concrete slab installed, installation done, concrete poured on top. And that within 1.5 days.
I can’t imagine that there was an opportunity to lay the pipes over 11 days.

In the last 11 days, the electrician could have found half a day to pull in the empty conduits.

However, he was not informed that there was a delay in the concreting of the ceiling. He was only told in the afternoon that he should do it the next day. He couldn’t do that, and then he was told that they would just have to drill through.

The electrician only found out sometime in the middle of last week that the concrete ceiling still wasn’t installed more than a week later. At that point, he was told again that he could come by briefly in the afternoon to do it, which again was too little notice. The ceiling was supposed to come the next morning. He was also not aware that it then took another four days.

I do think it is the site manager’s task to communicate accordingly with the trades in case of schedule changes. Even with separated trades, it could, if necessary, also go through the builder, but if I only find out about changes during site visits, I’m powerless as well.

Ok, in total there remains a lack of coordination between the GU and the electrician. However, in the end it is not a drama, because of course the electrician can also drill, he will also receive his sacred slip. Really, only the stressed client remains, who writes emails on weekends and threatens to stop the concreting.
