So the NIST WTC7 Final report was issued 20 November 2008 and can be found at the NIST web site. It seems it is basically the same as the draft final report and that all comments received were ignored.
However, it is quite easy to debunk this WTC7 NIST report. An attempt is at

Having done plenty of FEA and beam structural analysises myself, one rule is that you must use your own brains and check what the computer is coming up with. The loads must balance at every instance, etc.
In the WTC7 case the loads are just local weights on secondary (and tertiary) parts and they just stress the structure according to building standards (i.e. < 30% yield). That one major, primary part fails, cannot affect other primary parts to any great extent; evidently loads are redistributed but stresses are still low.
But NIST suggests otherwise. Adjacent primary parts are not higher stressed, they start to fail ... resulting in total collapse ... and free fall of all structure above floor 15/20!!
It is quite easy to fake such a result with a FEA software! You just add forces ad loads (stored energy) to and modify the connections between parts in the model. And voilà ... the structure collapses.
So - it is very easy to debunk NIST. Just ask any other institution to (try to) re-do the NIST FEA analysis. It is impossible.
