WTC 7 EVALUATION
A draft report of the study will be released in October or November 2017 and will be open for public comment for a six-week period, allowing for input from the public and the engineering community. A final report will then be published in early 2018.

The comment period for the evaluation that is not available started on Dec 1.
You got 44 days to publicly comment on the non-available evaluation.

Interesting that one of the largest buttons on the page is the "Support" button.
Just another money grab using 3000 dead people as the emotional tug.

I find it interesting the draft release date was missed
Philip Zelikow completed an outline of the commission’s final report, although the commission has barely began its work and will not report for another 16 months. The outline is detailed and contains chapter headings, subheadings, and sub-subheadings.
This is based on our calculations.
We don't know how the failures on other floors affected column 79. We don't know how the uneven heating of A2001 itself affected the way it expanded (your posts treat that girder as if were a uniform temperature).
In any case, Arup identified two cases in which A2001 would fail, and neither of them was the exact NIST scenario of being pushed to the west. In fact, both were essentially failures to the north/northeast, with the girder sagging and twisting away from the connection:
Each of the the NIST, Arup, and WAI studies were conducted by multiple PhDs with expertise in forensic engineering, tall building engineering or fire science, and the NIST WTC7 report was also independently peer reviewed by the Journal of Structural Engineering (whose editors and peer reviewers have similar levels of expertise), while not a single expert on forensic engineering, tall building engineering or fire science
There is only a single study (Hulsey's) that purports to reach a conclusion contrary to what the other studies have concluded re the vulnerability of WTC7 to progressive collapse from reasonable fire scenarios.
