The US gov NIST report said that it was fire that brought WTC7 down, nothing about foundation damage.
Even if as NIST state:
"Our study found that the fires in WTC 7, which were uncontrolled but otherwise similar to fires experienced in other tall buildings, caused
an extraordinary event," said NIST WTC Lead Investigator Shyam Sunder.
What is more extraordinary than fire bringing down a steel construction is that the building, damaged on one side, came down symmetrically, within seconds, into it's own footprint.
