ᐅ Concrete inside the ducts of the mechanical ventilation system with heat recovery

Hello!
We have a huge problem right now.
A few weeks ago, our installer placed the ductwork for the mechanical ventilation system between the steel layers of the ground floor ceiling.
The next day, the concrete ceiling was poured with cast-in-place concrete.
Today, when the installer wanted to connect the ducts and so on, it was noticed that concrete had flowed into two of the ducts.
Now the question is how this could have happened.
Could the ducts have been damaged by the concrete workers, or are they sturdy enough that this is unlikely?
Otherwise, the only possibility would be that the duct connections didn’t hold and came apart.
Do you have any idea how something like this might happen?
And above all, can someone tell me what can be done now to fix it?
Should the ducts inside the screed be reinstalled?
It would be great if someone experienced could give me a few tips so we don’t look clueless at the appointment with the installer tomorrow. Of course, everyone will probably try to avoid taking responsibility for the damage to avoid paying for it...

I’m really curious about the details. It sounds a bit too simple to me, and I can hardly believe such a significant change in the construction method is easily possible.
In any case, will the affected pipes be completely relaid along their entire length? Are there intersections with other lines that are already installed on the raw ceiling slab?
Edit: Embedding them in the screed would probably not be technically correct (minimum coverage and all).
