The Skyscraper is just an event synced to all clients after it’s triggered. If your looking for battlefield destruction, the way it seems to be set up is a wall segment checks for the damage type and blows up (deletes) and plays a particle affect, after that, a damage mesh is placed for that segment. In UE4, you can use destructable meshes and tell the wall to blow up for everyone. The chunks do not need to be replicated and you just need a bool. I use to have a video showing this but i must of took it down.
EDIT: Rainbow Six Siege does it completely different than battlefield.
