You still have yet to post his exact quote saying that the analysis they did showed the affects of fire on the steel!!!!
The only thing you post are quotes from Skilling and supposed quotes from Robertson that one has to make an assumption about in order see what you are claiming. That is not a quote. Not even close.
My intention was to show the contradictions that have come from Robertson, and I have done that, and here they are in more detail.
It looks like in the article you linked, we also find a couple of the considerations that were utilized due to their analysis in case of fires:
"Another
theory was developed to predict stack action and temperature-induced and wind-induced airflow within a high-rise building; an understanding of these airflows is crucial to controlling fire-generated smoke and reducing the energy consumption of the building."
"We developed the concept of and made use of the fire-rated shaft-wall partition system, which is now widely used in place of masonry and plaster walls. At that time, masonry was the standard enclosure for elevators, stairs, duct shafts, and other internal structures."

And this, taken from the
NOVA article you linked:
"Exclusive footage shows off the skyscraper's massive structural shell, "refuge floors"
with extra fire protection, and additional elevators designed for use by emergency personnel. While Robertson is relieved that the NIST investigation found no flaw in his engineering of the World Trade Center, the horror of what happened to the Towers still haunts him to this day."

Regarding John Skilling and who was the boss:
"NIST found a three-page white paper that mentioned another aircraft-impact analysis, involving impact of a Boeing 707 at 600 miles per hour (970 km/h), but the original documentation of the study, which was part of the building's 1,200 page structural analysis, was lost when the Port Authority offices were destroyed in the collapse of the WTC 1; the copy was lost in WTC 7.[10] In 1993,
John Skilling, lead structural engineer for the WTC, recalled doing the analysis, and remarked, "Our analysis indicated the biggest problem would be the fact that all the fuel (from the airplane) would dump into the building. There would be a horrendous fire. A lot of people would be killed," he said. "The building structure would still be there."
Collapse of the World Trade Center - Wikipedia, the free encyclopedia
If you feel there is an error, perhaps you could edit the Wikipedia page and correct it, because here it mentions Skilling once again as being the lead engineer:
"John Skilling (October 8, 1921, Los Angeles, California – March 5, 1998, Seattle, Washington) was a civil engineer and architect, best known for being the chief structural engineer of the World Trade Center.[1]"
"John started working for the W.H.Witt Co. soon after graduation. In 1983, he became the chairman of the firm. Prominent constructions under his leadership include the World Trade Center, Rainier Bank Tower, the Seafirst Building, Seafirst Fifth Avenue Tower, Century Square, Columbia Seafirst Center and the Washington State Convention and Trade Center.[2]"
"John Skilling, American structural and civil engineer whose firm, Skilling Ward Magnusson Barkshire, designed over 1,000 buildings in 36 states and 27 countries; among his best-known work was the 110-story twin towers of the World Trade Center in New York City (b. Oct. 8, 1921, Los Angeles, Calif.--d. March 5, 1998, Seattle, Wash.)."
John Skilling (American engineer) -- Britannica Online Encyclopedia
"Skilling became a principal of the Witt firm in 1950. He led the evolution of a small, regionally oriented firm into the nationally acclaimed structural engineering organization that it became over the nearly 45 years of his direction."

So, Robertson answered to Skilling, apparently until he was made a partner.
Leslie Robertson is often represented as the lead engineer in the engineering firm that designed the Twin Towers: Worthington, Skilling, Helle and Jackson. Robertson has become an apologist for the official story, while the actual lead architect, John Skilling, is not alive to defend his buildings, having died in 1998.
Skilling seemed to remember considering fires in his analysis, but Robertson was not remembering any of it.
The controversy caused by contradicting statements is further detailed in an analysis of contradictions in statements by Building Designer Leslie Robertson--
What the World Trade Center Building Designers Said: Before and After 9/11
(Between Early 1984 and October 1985): Office of Special Planning Studies Vulnerability of WTC to Terrorist Attack
The Office of Special Planning (OSP), a unit set up by the New York Port Authority to assess the security of its facilities against terrorist attacks (see Early 1984), spends four to six months studying the World Trade Center. It examines the center’s design through looking at photographs, blueprints, and plans. It brings in experts such as the builders of the center, plus experts in sabotage and explosives, and has them walk through the WTC to identify any areas of vulnerability. According to New York Times reporters James Glanz and Eric Lipton, when Edward O’Sullivan, head of the OSP, looks at WTC security, he finds “one vulnerability after another. Explosive charges could be placed at key locations in the power system. Chemical or biological agents could be dropped into the coolant system. The Hudson River water intake could be blown up. Someone might even try to infiltrate the large and vulnerable subterranean realms of the World Trade Center site.” In particular, “There was no control at all over access to the underground, two-thousand-car parking garage.” However, O’Sullivan consults “one of the trade center’s original structural engineers, Les Robertson, on whether the towers would collapse because of a bomb or a collision with a slow-moving airplane.” He is told there is “little likelihood of a collapse no matter how the building was attacked.” [Glanz and Lipton, 2004, pp. 227; New York County Supreme Court, 1/20/2004] The OSP will issue its report called “Counter-Terrorism Perspectives: The World Trade Center” late in 1985 (see November 1985).

Between September 3, 2001 and September 7, 2001: WTC Structural Engineer Says Trade Center Designed for 707 Crashing Into It--
Leslie Robertson. [Source: Publicity photo]Leslie Robertson, one of the two original structural engineers for the World Trade Center, is asked at a conference in Frankfurt, Germany what he had done to protect the Twin Towers from terrorist attacks. He replies, “I designed it for a 707 to smash into it,” though does not elaborate further. [Chicago Tribune, 9/12/2001; Knight Ridder, 9/12/2001] The Twin Towers were in fact the first structures outside the military and nuclear industries designed to resist the impact of a jet airplane. [Robertson, 3/2002; Federal Emergency Management Agency, 5/1/2002, pp. 1-17] The Boeing 707 was the largest in use when the towers were designed. Robertson conducted a study in late 1964, to calculate the effect of a 707 weighing 263,000 pounds and traveling at 180 mph crashing into one of the towers. He concluded that the tower would remain standing. However, no official report of his study has ever surfaced publicly. [Glanz and Lipton, 2004, pp. 138-139, 366]
Also according to the authors of a book entiled City in the Sky: The Rise and Fall of the World Trade Center-By James Glanz and Eric Lipton
Robertson says in 1984-5 that there was "little likelihood of a collapse no matter how the building was attacked." Page 224
A previous analysis, carried out early in 1964, calculated that the towers would handle the impact of a 707 traveling at 600 mph without collapsing (see February 27, 1993). In 2002, though, Robertson will write, “To the best of our knowledge, little was known about the effects of a fire from such an aircraft, and no designs were prepared for that circumstance.” [Robertson, 3/2002] The planes that hit the WTC on 9/11 are 767s, which are almost 20 percent heavier than 707s. [Scientific American, 10/9/2001; New Yorker, 11/19/2001]
More contradictions,
In the audio conversation, that I linked, and that Robertson had with Jones, Robertson claims that he had never run across anyone who has said that they had in fact seen molten metal. This statement is also a contradiction, considering the fact that Robertson himself claimed to have seen it in a published news report! This contradicts his own statement about seeing molten metal: Leslie Robertson, one of the structural engineers responsible for the design of the WTC, describes fires still burning and molten steel still running 21 days after the attacks.
"As of 21 days after the attack, the fires were still burning and molten steel was still running." -- Leslie Robertson, at the National Conference of Structural Engineers on October 5, 2001, James M. Williams, "WTC A STRUCTURAL SUCCESS," SEAUNEWS, The Newsletter of the Structural Engineers Association of Utah, Volume VI -- Issue II, October 2001, p.3.
Furthermore,
The World Trade Center (WTC) Towers[1] were the largest buildings ever conceived in 1960.[2] This meant that there was a considerable amount of planning:
“The structural analysis carried out by the firm of Worthington, Skilling, Helle & Jackson is the most complete and detailed of any ever made for any building structure. The preliminary calculations alone cover 1, 200 pages and involve over 100 detailed drawings… The building as designed is sixteen times stiffer than a conventional structure. The design concept is so sound that the structural engineer has been able to be ultra-conservative in his design without adversely affecting the economics of the structure.”[3]
In July of 1971, the American Society of Civil Engineers (ASCE) presented a national award judging the WTC Towers to be “the engineering project that demonstrates the greatest engineering skills and represents the greatest contribution to engineering progress and mankind.”[4]
Like many modern structures and buildings, the WTC Towers were over-designed to withstand weight distribution in the event of structural damage. According to calculations made by the engineers who helped with the design of the Twin Towers, “all the columns on one side of a Tower could be cut, as well as the two corners and some of the columns on each adjacent side, and the building would still be strong enough to withstand a 100-mile-per-hour wind.”[5] As well, “Live loads on these columns can be increased more than 2,000% before failure occurs.

Thompson explains that “besides this paper, no documents are known detailing how this analysis was made.”[18] In fact, many of the building documents are unavailable because “the building owners, designers and insurers, prevented independent researchers from gaining access—and delayed the BPAT team in gaining access—to pertinent building documents largely because of liability concerns.
It is demonstrable that the WTC building designers claimed that the Twin Towers would survive an event similar to 9/11. Either the WTC building designers were tragically wrong in their calculations and designs, or there is another explanation for the destruction of the WTC Towers. After 9/11, WTC building designer Leslie Robertson has made claims that are contradicted by statements and documents from as many as 40 years ago.
The World Trade Center Building Designers: Pre-9/11 claims strongly implicate Towers should have remained standing on 9/11 | NowPublic News Coverage
Is Robertson being pressured to lie and make false statements? Was he asked to leak a false statement just before 9/11 about the speed of the planes having an impact on their destruction? Are these contradictions by accident or mistake?
A news report stated that he wanted to give his opinion to the FBI before making his comments public. This in itself is not overly suspiciousbut his contradictions are. No clear answers to these and similar questions can be obtained through speculation alone Leslie Robertson must account for these himself. If another 9/11 investigation is obtained, it is clear that Leslie Robertson will have to answer these and other relevant questions.
What the World Trade Center Building Designers Said: Before and After 9/11
So this shows that my original intention,
to prove that Robertson has said conflicting things before, and after the WTC 9-11 attacks, is valid, and well documented.
Do you still think the designers did not do any analysis concerning plane impacts and the fires from the jet fuel?
You probably will, and in so doing degrade their intelligence to further your stubborn beliefs and assumptions.
Are you still going to ask for any documentation about the "analysis" when even NIST has admitted the difficulty in obtaining such documentation?
All we have is the words of the designers themselves. One who is not alive to comment, but is recorded by many sources to have said considerations and analysis were done, and the other who was hired by the owner of the firm, and who is well documented showing that he likes to change his story?
The engineer who said after the 1993 bombing that the towers could withstand a Boeing 707, Leslie Robertson, was not available for comment yesterday, a partner at his Manhattan firm said.
We're going to hold off on speaking to the media, said the partner, Rick Zottola, at Leslie E. Robertson Associates. We'd like to reserve our first comments to our national security systems, F.B.I. and so on.
Why would he have to wait to speak to the FBI? To get the story straight, and make sure it lines up with the "official accounts"?
I guess that depends on who you choose to believe.
