Where are you getting this information? Everything I've seen shows that it would take about a week to set a building up for controlled demolition assuming you have a crew of experienced workers to do it.
However, to rig it all up while people are still working there and do it without anyone noticing would take significantly more time. Or every person in that building would have to be oblivious or in on the plan. Which sounds unlikely.
Primarily from the Architects and Engineers for 9/11 truth movement which uses science. NIST (goverment) officially declared its collapse due to fires, which makes building 7 the only steel structure in history to have a complete collapse for that cause (note: building 7 was designed to hold the FBI, CIA and Rudy Giuliani's bunker was also located there.)
Building 7 fell at free fall speed on 9/11 that afternoon. It fell at free fall speed for about 7 seconds or so, the governments conclusion of its collapse is scientifically impossible. NIST didnt even check for explosive! lol although scientists found nano thermite at the scene (highly flammable paint.)
You can check out this website and they lay out the evidence, you can look though alot of info there, and there is also the Architects and Engineers website as well.

Here is short video footage of the collapse. Notice how the penthouse on top collapses first, and then the building crimps inward and then down at free-fall speed. Its without a doubt scientifically impossible to achieve from just fires. All the columns were taken out simultaneously, the level of achievement for this controlled demolition is quite accurate and remarkable for this type of steel structure building.
