So are you saying the building was rigged before 9/11?

What's your definition of "footprint"?
CDs are more precise so as to not severely damage buildings across the street (as wtc7 did).

I will accede to "designed that way" and will even assume "constructed that way." If the trusses and concrete are expanding against the exterior columns and inner core columns, would that not stress the 5/8 bolts at the joints? Would you claim that they would not break under such stress? If you were to calculate the difference in length due to expansion of a 400 to 500 C temperature rise, how much longer would they get? What would happen after they failed?

how so? The entire side of the structure was aflame.
The fallacy that most believe is that it was a small 2 floor office fire.
uh, no. it was an all-inclusive fire. The fact that a side of the structure was gone also helped.
this structural damage did not initiate the collapse... None of the large pieces of debris from WTC 2 (the south tower) hit WTC 7 because of the large distance between the two buildings.
Would WTC 7 have collapsed even if there had been no structural damage induced by the collapse of the WTC towers?
Yes. Even without the structural damage, WTC 7 would have collapsed...

I wonder if they're going to let the burnt out hulk of the building sit there for 6 months and be a safety hazard so they can do a "proper" investigation like the "truthers" would want? Instead of cleaning up the dangerous area as soon as possible, hauling away and properly disposing of the debris.
"Thousands of tons of steel were carted away from ground zero and recycled before any expert could examine what could have been tell-tale clues. Support trusses, fireproofing fragments and even burnt out electrical switches that might have given scientists and engineers insight were lost forever - even before an investigation was underway.
Also, I wonder if they're going to do a proper investigation such as making sure a plane didn't hit the building and start the fire, or check the molecular cohesion of the steel to make sure high energy beam weapons didn't disassociate the steel supports molecules? Or check to see if arab workers went into the building earlier and planted thermite charges? Because we all know if they don't check all those things, then they didn't do a proper investigation and/or they are covering up what really happened.
Just some thoughts about how similar these situations should be based on previous complaints from some "truthers" .

This actually proves the point, in that some Controlled Demo's have gone wrong and damaged other buildings. But the general direction of straight down suffices for footprint.

You're a professional liar:
Just after the disaster, Firefighter Louie Cacchioli said, "We think there were bombs set in the building."

Damned straight -- firefighters are afraid of losing their jobs.

Just an FYI
Coefficient of Thermal Expansion
10-6/°C 10-6/°F
Concrete 7.4-13 4.1-7.3
Steel 11-12 6.1-6.7
because PCC materials vary considerably. Realistic data for the types of materials being used in concrete mixtures are rarely available and, if they are available, they are likely to be based on a specific PCC mix design or aggregate type. However, an agency could test typical mixes containing a range of aggregate types to obtain typical values for their materials.
Might give you a basic idea for what you're discussing.
Three physical characteristics give reinforced concrete its special properties. First, the coefficient of thermal expansion of concrete is similar to that of steel, eliminating internal stresses due to differences in thermal expansion or contraction. Second, when the cement paste within the concrete hardens this conforms to the surface details of the steel, permitting any stress to be transmitted efficiently between the different materials. Usually steel bars are roughened or corrugated to further improve the bond or cohesion between the concrete and steel. Third, the alkaline chemical environment provided by calcium carbonate (lime) causes a passivating film to form on the surface of the steel, making it much more resistant to corrosion than it would be in neutral or acidic conditions.

Hey "Talisman", are you questioning the WTC Towers Collapse, or only Building 7?
Because as far as the Twin Towers go (Buildings 1 and 2), they were inundated with Jet Fuel (JP-8), which does not burn like a regular fire.
As for Building 7, well, that depends on a lot. For one, the Seismic Tremors unleashed by the Twin Towers collapsing would have weakened any building nearby that just so happened to resonate at the same frequency as the tremors (depends upon Building Materials, Foundation type, Ground Structure, etc.). Also, there is a maze of Underground connections between the WTC Towers, and Building 7, which includes an Underground Shopping Mall, Subway Tunnels, and Walkways.
Also, do not forget the Underground Parking Garages, which could have easily become a repository for smoldering Jet Fuel, as well as Vehicles full of Gasoline and Diesel.
Fires that kindled from the fuel in the planes were too shortlasting and weak to be able to severely damage the structure of the skyscrapers. Even in the extreme situation, the heat from a kerosene fire cannot threat the durability of a steel trunk. With the temperature of carbohydrate fires that reaches only 825 °C (approx. 1517 °F) steel weakens at 800 °C (approx. 1470 °F) and melts at 1585 °C (approx. 2890 °F). In the skyscrapers of the WTC the surroundings were not at all ideal as there were far too many steel columns and they led heat away from the burning area. WTC 1 burned for 102 minutes and WTC 2 for 56 minutes only. A fire burning much longer, from 10 to 20 hours, could slowly increase the burning temperature down to perhaps 1100 °C (approx. 2010 °F). Provided there is more substance to burn, such a fire will damage concrete and irons, but not severely heavy steel constructions.

Isn't thermate an oxygen or sulfur boosted thermite? That would require the inclusion of a metal oxide reducible by Aluminum. Thermite uses black iron oxide.

Wait, are you implying they set up thermate charges after it collapsed? You can't be serious.
Based on that photo, I have no idea when they were cut. They could have been cut as part of final demo long after 9/11.

We can only go on the ethics of the people involved in the investigation.
You know, like the people who gave the all clear on air quality, while they added air filters to their offices, and now many of the first responders are dead with lung diseases.
We don't know if they were cut before or after -- because the FBI were not allowed to investigate.

Now is this just another guess/accusation ? or do you actually have any evidence to suggest anything you just said was true?
Let's say what you're saying is true:
So the following people would have been involved:

I've already posted a photo showing them being cut...AFTER the collapse.

I saw a photo of the building IMMEDIATELY after the collapse. Jagged steel that looked cut.
