The firefighters could see the structural damage to WTC7. They could hear it creaking, and they could see it leaning. Those are symptoms. The result of those symptoms was obviously going to be collapse, especially when they knew there was no way they could fight the fires.

Firefighters and NIST weren't exactly clueless of the weaknesses of WTC7, but they had no way of knowing the exact cause until a proper scientific study was completed.

NIST had to discover the exact weakness in WTC7's design to prevent a repeat collapse. Heavy debris from the collapsing WTC1 and subsequent fires exposed WTC7's design weaknesses.
