Another amazing coincidence related to the WTC

There appears to be a remarkable correlation between the floors upgraded for fireproofing in the WTC towers, in the years preceding 9/11/01, and the floors of impact, fire and failure. The fireproofing upgrades would have allowed for shutdown of the affected floors, and the exposure of the floor assemblies and the columns for a significant period of time. Exactly what work was done during that time?

In some sections of the NIST WTC report, the exact floors upgraded are listed. Other sections of the report suggest even more floors were upgraded, a total of 18 floors in WTC 1 and 13 floors in WTC 2, but the additional floors involved are not specified.[1]

WTC tower floors upgraded for fireproofing and floors of impact, fires and failure on 9/11 (click for full size)

This relationship is unmistakable for WTC 1. Some investigators have pointed out that a number of floors failed simultaneously in this tower, in accordion-like fashion, before the rest of the building began to 'collapse'. These floors seem to match up almost exactly with the floors that were upgraded. See the film clip below, and the following Powerpoint sequence created by Gregory Urich.

Two blueprints for the 1999, 2000 construction upgrades to WTC 2, provided by a supporter, indicated that the work was done at almost exactly the point of impact and failure in that tower. That is, the southeast quadrant of WTC 2 was the focus of the work, at least on the 78th floor (the blueprints provided were for floors 77 and 78 only). It was the southeast quadrant of WTC 2, at and just above floor 78, where flight 175 hit.

We have also seen video of molten metal pouring from WTC 2 prior to its destruction. The relationship between fireproofing upgrades and the pouring metal is close but not exact, as the molten metal seen in videos appears to be coming from floors 80 and 81. Communication to the NIST team from Frank Lombardi of the Port Authority, in 2002, indicated that only floor 78 of the impact failure floors of WTC 2 had been upgraded. But NCSTAR 1-6A (table 4-2, p 45) lists floor 85 as an upgraded floor as well. Could it be that certain areas within floors 79 to 84 were upgraded also, and not reported because the floors were not fully upgraded?

For the north tower at least, it is difficult to accept that this relationship is yet another unbelievable coincidence related to 9/11. Certainly the upgrade work allowed for access to critical areas. But in considering this, a number of other, admittedly far-fetched questions come to mind. Why was the upgraded fireproofing measured to be twice the thickness specified?[2] Could incendiary or explosive materials have been embedded within the upgraded fireproofing? Could these “construction” activities have involved installing mechanisms to direct the planes to the specific areas in which they hit each building?

In any case, the demolition hypothesis should be considered more than just simple demolition. If the idea was to create the appearance of a fire-induced collapse, then a fiery presentation was needed, much more than the jet fuel/office furnishings would have been able to provide. It seems that thermate may have been used not only to weaken or cut the steel infrastructure throughout the buildings, but also to help create that fiery presentation near the floors of impact.

It seems possible that a thermate-like material, and/or other devices contributing to the destruction of the towers, could have been incorporated on the floors of impact and failure during the fireproofing upgrades. The access for such an operation would have been facilitated by the activity surrounding the fireproofing upgrades.

[1] NCSTAR 1-6A, page xxxvii, indicates which exact floors were upgraded. NCSTAR 1-6, page 20 repeats these claims, as noted in the figure above. Elsewhere in NCSTAR 1-6, on page lxxi, NIST muddies the water by saying “18 floors in WTC 1, including all the floors affected by the aircraft impact and fires" and “"13 floors in WTC 2, although none were directly affected by the aircraft impact and fires.". On this last part, NIST contradicts itself yet again in NCSTAR 1-6 (on page lxvii-lxix) by stating that some of the floors upgraded in WTC 2 were affected by the impacts and fires (notably floor 78). As with the contradictory amounts of jet fuel referenced throughout NIST’s report, these fireproofing upgrade statements appear to be another example of how detailed findings in the NIST team’s lower level reports were confused or made vague in higher-level reports.

[2] NCSTAR 1-6A (p xl) states “The overall average thickness determined from the 356 individual measurements was found to be 2.5 in, with a standard deviation of 0.6 in.” The same report (p 44) says “Note that some of the average thicknesses shown in Table 4-2 equal or exceed 3.5 in. No photos were available of upgraded floors to show the appearance of such high average thickness of SFRM.” Floor 94 of WTC 1 stands out in this data, with a SFRM thickness of more than 4 in. The specification for these upgrades was only 1.5 in, increased from the as-built specification of 0.75 in.

Do we know who performed or was contracted to do this upgrade work?

Has anyone pursued that angle?

Radical Pragmatist

It would seem someone in law enforcement should

I would hope that with information like this coming forth that someone in law enforcement should start looking at these types of strange coincidences. I would think that anyone living in New York City can contact the New York District Attorney to at least apprise them of this information.

Put the D.A. on this straightaway!

Surely you jest.

Wait, I have a better idea: Let's write to Mayor Bloomberg, asking him to set up a city investigating commission. He should assign former Mayor Giuliani as chairman, with Larry Silverstein as the vice chairman. By putting only the best people in charge, we can get to the bottom of this thing in no time!

Public Record

Actually , I believe all Work Permits are public record and must include not only a detailed blueprint and outline of the project but also the name and licence # of thecontractors who will be performing the work.

The project must also be inspected and approved by the city at each stage of the renovation to insure it meets the safety codes for that project. This is also to protect the 'ass' of the contractor from future liability because the city has given their work its "seal of approval".

I was in construction for years and thats how it always worked in the cities and states I worked in. You would probably have to look it up at the local Building dept of records for that precinct in NY.

Radical Pragmatist

Public Record?

Ha, ha, ha. The Port Authority is not subject to such things. Nor did they have to abide by no stinking building codes, if they didn't feel like it.

Mechanical Floors

I´ve always thought the Mechanical floors were key points in the demolition.

called technical Services floors in the drawing

This may be informative:

(as posted below on the thread..)

on bollyn and iamthewitness

Why are you posting a link to an anti-semitic attack site with no warning? Even if for some reason someone has unique information, you could at least mention what the site is about.

The referenced article

asserts a point that the impact of each plane into the towers directly corresponds to secure computer rooms, as confirmed by resident workers & witnesses.

In addition to curious circumstances surrounding the rooms (inc. late installations & apparent dormancy), an implication is that these stored ‘batteries’ may have functioned as homing-devices, thereby augmenting Mr. Ryan’s noted coincidence of upgraded floors.

One of the companies was Leslie E. Roberston Associates

The same company that built the Towers. The project is cited on their website:

A few more clues in regards to the upgrades that were done

Still no mention of who they contracted to do the work, but could there be a dual-use reason to switch to copper wire?


Copper cabling helps multiply power capacity at WTC

September 1 1993

Since the World Trade Center (WTC) opened its doors in New York City 22 years ago, growing clusters of electronic devices have begun to burden the center's electrical system, which contains some 3,000 miles of electrical conductors and about 100,000 lighting fixtures.

To address the situation, the Port Authority of New York & New Jersey, the WTC's owner, has decided to revamp the system with an electrical upgrade that will take an estimated 10 years and $81 million to complete. The project will involve extensive use of copper cabling.

The WTC's electrical system was originally designed to provide tenants with four watts of power per square foot, but today's computers, facsimile machines, and advanced telephone systems require more power. "We're finding that tenants are now requiring a doubling of capacity to operate some of their highly sophisticated electronic equipment," says Robert DiChiara, WTC assistant director. Capacity will be increased to between eight and 10 watts per square foot.

The WTC's six buildings are powered by the New York City utility Consolidated Edison Co. Presently, Con Ed provides eight feeders running to 23 substations throughout the center. Boosting wattage to the complex will involve increasing the number of feeders to 10. The change will also increase reliability.

The first step in the upgrade program will be to replace aluminum cables with copper cables from the complex's power distribution center to the 41st floor. Four transformers will also be replaced with copper wound transformers.

Some 13,760 feet of copper cable will be installed in horizontal runs from the primary distribution center to the buildings, while 8,800 feet of high-voltage feeder cable will be installed in vertical risers. Copper was selected for the mammoth project because it can handle the higher capacity required, and can be installed easily into existing conduits.

Still, the project will not be a cakewalk, says Charles Semah, staff services engineer at the WTC. "But the extra effort to use heavier cables is outweighed by their ability to deliver much more power reliably."

WTC officials are also concerned about saving energy. "We've been in the energy-saving mode since 1973 and have taken advantage of every opportunity concerning base building systems. That's one of the reasons for selecting copper for this upgrade," says DiChiara. Information about copper building materials from the Copper Development Association, Inc.


Excellent discovery Kevin ...

Another piece of outstanding correlation evidence, additional material for answering question from people who ask, "When did they have the opportunity to plant all the explosives/thermate, besides the week downtime right before 9/11?

Note to Kevin ***

Last year I attended a lecture by William Rodriguz, last person out of WTC, he mentioned during the course of his presentation about a section of floors that were off limits and maintenance personnel were given very strict orders that NO ONE was allowed to go there. He said when he was in the rooms just under the restricted floors he could hear all kinds of noise above, to the point he was even scared.

It might be productive to contact him and see if the floors match the same ones in your discovery.


and Kevin R:

Interviews of Rodriguez appear in the video '9/11 Mysteries'.

At 33min, he says that he heard explosions in his tower (North) seconds after the South tower impact. Then his security radio said 'we lost 65', which he took to mean damage on the North tower 65th.

At 1hr20min, he says he heard 'heavy equipment' noises on the 34th floor and did not open the door.

Thx Kevin O

Thanks for the heads up Kevin O.

I've been wondering about this

"he says he heard 'heavy equipment' noises on the 34th floor and did not open the door."

What could those noises have come from? It wasn't long before the tower would be destroyed.

Good work! Thanks for all

Good work! Thanks for all your efforts.

It gets curiouser and curiouser every time...


VERY interesting ...

Great find! Thanks for posting!

Crew lists. contractor lists

I would love to see a complete crew list, names, company names, addresses, affiliations, of all workers who did the fire upgrades and cross reference this with
prior activities in other careers. Certainly a list such as this exists somewhere. I work in construction. This type of data is recorded for tax purposes, workers comp, insurance, experience accrual and so forth.
Where is the damn police work? Ya I know, suppressed. Perhaps some angel like the one who leaked the floor prints to you Kevin can be found to answer my questions.

Thanks for producing this report Kevin.


Initial collapse floors

According to NIST, the floors on which the collapse starts/first becomes visible are 98 in the North Tower and 82 in the South Tower (e.g. NISTNCSTAR1, p. 87). I checked these against various photos and they seem to be right about the North Tower, but I couldn't really tell for the South Tower. 98 had its flooring upgraded, but 82 didn't.

The 81st floor was a crucial floor

The 81st floor in both Towers were mechanical floors where a dozen 24 ton elevator hoists were housed.

This is the same floor in WTC 2 (I believe) that supposedly had extensive work done to install battery backups for one of the tenants computer systems.

The 81st floor had beams instead of trusses (not sure if it was the whole floor, or just under the elevator hoists) and thicker columns then the floors directly below. In a CD, this would be a key floor to take out first because of the stronger construction and in order to release the kinetic energy created by dropping the elevator hoists on the floors below.

Seems different reports don't all agree about with floor failed first. I remember one of the NIST reports cited the 81st floor and the FEMA reports cited the 80th Floor. I think a section of floors all failed simultaneously and that the core section of those floors was blown up first, via explosives in the elevator shafts.

Also, the mechanical floors directly below 81, 75-77 had another structural difference that was likely exploited in a CD and that is the way the columns were set. On the regular floors the columns were staggered, however on the mechanical floors 75-77 and 41-42 the columns were set at an even height, which created seams that around the perimeter of the building. Architecturally this was considered a weak spot, which I believe was exploited

The mechanical floors don't usually have too many tenants, so these are easy places to work without anyone ever noticing and even if someone did see a guy working, how the hell would you know if those wires might be for a fuse or someone's new lighting fixtures? People think it would be hard for teams of people to get the buildings ready for CD, when in fact, it would have been ridiculously easy, especially when you had folks like Paul Bremer and Jerome Hauer to provide all the access anyone would need to do the work. One of the big reasons for the 1993 Bombing was to give them an excuse to do major renovations to the entire complex.

impact zone or simulation zone?

This is stunning. I propose that this "impact" zone of the building was rigged for fiery explosives (some have suggested napalm) to simulate the dramatic airplane crash. this is the zone of the building that had no thermate to ignite inadvertently during the simulation whereas the remainder of the building did have thermate cutter charges to actually bring down the building.

It is Objective Facts such as These

...Which are solid grounds for either demanding new investigations or issuing supoenas outright in hostile litigation.

Explosive stuff !
Pure TNT
Good 4 you Kevin !

Reminiscent of the Pentagon, in that the small upgraded wedge

was impacted & destroyed by AA-77 (and/or something else).

And WE are supposed to be the ones

cherry picking evidence to fit our pre conceived hypothesis?
We stumble over lie after lie even if we try to walk in a straight line, that's the truth!

Corollary Evidence

If there were possible homing devices, this data makes a striking connection:

Great find, Kevin!

Great find, Kevin! Excellent work as usual.

Another interesting coincidence

are the occupants of the impact zones.

In WTC 1, the impact zone floors main tenant was Marsh USA..

L Paul Bremer III was the CEO of Marsh Crisis Consulting Company, a crisis management firm owned by Marsh USA.

In WTC 2, Fuji Bank and the Dow Jones Co. were the main tenants in the impact zone. The computer upgrades on the 81st floor were supposedly done for Fuji Bank. It is also possible that Fuji Bank and Dow Jones could have been connected to the put options on the airline stocks.
