Structural Drawings / Shop Drawings Available for Download!Editor’s note: The release of detailed construction documents and shop drawings for WTC Building 7 is the latest in a series of FOIA successes by AE911Truth supporters. Recent efforts have also led to the acquisition of revealing video recordings of the WTC catastrophe, and forced the NYC Department of Buildings to claim that the release of WTC renovation plans for the years leading up to 9/11 would “endanger the life or safety of any person.” If you are interested in helping us examine these important construction drawings, please consider joining our Volunteer Team. The Freedom of Information Act (FOIA) Office at NIST recently released over 2,600 electronic files pertaining to the NIST NCSTAR 1A: Final Report on the Collapse of World Trade Center Building 7, and NCSTAR 1-9: Structural Fire Response and Probable Collapse Sequence of World Trade Center Building 7. These files include original structural design drawings, shop fabrication drawings and steel erection drawings of the third skyscraper to fall on 9/11, and are ready for architectural and engineering professionals and students to analyze. Anyone can file a FOIA request. FOIA #11-209, shown below, was a simple and specific request:
FOIA #12-009 was also specific in its request for the following construction documents: • Frankel Steel Limited (1985). Erection Drawings, 7 World Trade Center • Frankel Steel Limited (1985a). Fabrication Shop Drawings, 7 World Trade Center The 2,587 files released through FOIA #12-009 include steel erection plans, column schedules, bracing elevations and details. Of these, 22 sheets in PDF format include erection drawings for floors one through 17, and 42 sheets in TIF format include erection drawings for the entire building. The remaining 2,523 sheets in TIF format illustrate various fabrication details throughout the structure. FOIA #11-209: FOIA #12-009: • Locate the plan sheet of the floor you are interested in. For example, drawings S8 and E12/13 show floor framing at floor 13—the location where NIST claims collapse initiation occurred. • Locate the area of the floor you are interested in. For example, the girder between columns 79 and 44 is located near the northeast corner. The girder is labeled W33x130, indicating the size and weight of the steel section. The girder is also labeled A2001on erection drawing E12/13. A2001 is the shop fabrication sheet number where the girder was detailed. Unfortunately, all sheets numbered from 2001 to 2999 were not included in the drawings released. The NIST FOIA Office indicated they did not have a complete set of the Frankel Steel drawings. • Column 79 is labeled A1091 on sheet E12/13, and column 44 is labeled A1370. These are the shop fabrication sheets where details of the girder connections are shown. Obviously the design, detailing, fabrication and erection of WTC 7 took several years from start to finish. It is not obvious how NIST can claim that fires fueled by office furnishings could have compromised this steel structure in a matter of hours and destroyed it in a matter of seconds. Hopefully these design and fabrication drawings will shed light on the third worst structural failure in modern history.
