I don't believe the tower demolitions were as difficult as some paint it to be. They didn't have to be universal or intricate as in a traditional CD.
I believe explosives would simply have been planted in the core columns only at certain levels, maybe corresponding to the squibs. Just as an assistance to gravity - not precision.
Each explosive would have been independently radio-controlled. No wiring at all.
Here is a 1986 patent similar to what I mean.
Please do not bother debunking the details of this device as I am not in a position to respond to the technical details.
Suffice to say that if each explosive had a separate remote control unit timed through a control board that provided a detonation sequence it could work.
So if every 100 feet or so up the building you had explosives in the core only at the most critical weight bearing columns that were independently, electronically controlled in a downward sequence it is conceivable.
I imagine they had inspection access points to the core columns. Somebody can elaborate if I am wrong. If it is true then you don't have people romping around all over the building laying wires and packing explosives in plane site. It would all be hidden.
The key to something like this would be simplicity and minimization. If you believe the building could fall in the manner it did from gravity and damage, I believe it could fall from some intentional destruction of the core only with a minimal number of explosives.
No matter where the planes hit, the explosives above and below would not be contingent on each other. After assessing the impact damage you could decide the detonation sequence in the control board of the explosions and have at it from a distance.
Newsday reports allege that the bomb dogs were only removed shortly prior to 9/11.
I don't know all of the debate over the power down situation on the 6th and 9th but it could be factored in. Maybe somebody can tell me which parts of that claim still stand if any.

"Explosive charges are detonated by remote control in environments having high levels of extraneous electric and electromagnetic energy by providing a separate control unit for each explosive charge. The control unit accepts coded commands radio transmitted from a command unit and, if those commands meet with pre-set criteria, the control unit detonates the charge. Each control unit is connected to its respective explosive charge by electrical or optical conductors providing sufficient separation as to allow the control unit to survive detonation of the charge without damage."

So my guess is that my scenario would have happened over a 5 day period."The World Trade Center was destroyed just days after a heightened security alert was lifted at the landmark 110-story towers, security personnel said yesterday.
Daria Coard, 37, a guard at Tower One, said the security detail had been working 12-hour shifts for the past two weeks because of numerous phone threats. But on Thursday, bomb-sniffing dogs were abruptly removed."
