Yeah, I made it. Your idea inspired me -
One of my companies did the specifications for large buildings (I know, I have done a LOT of shit - I find it hard to believe too when I hear myself say these things - but they are all true). But you know, we never got into this topic of a building's removal. Contractors handled all that according to building codes. The idea of planned destruction and removal (obsolescence) however, is one which sends the mind down creative pathways - and that is what humor does. So you were humorous by instinct - triggering the creative pathway.
A building is constructed with its eventual removal in mind. Sort of like an Exit Strategy in a business plan. If your building is large and flat, you want modular standardized components which assemble, disassemble and transport easily, (and can be reused even). We are just now getting to where standard panels, vertical and horizontal load members are assembled by means of pouring concrete in the field. If your tall narrow facility exists in the middle of a lot of other tall structures (as they are wont to do) - one necessarily and ethically must ensure that, in any calamity, the building is biased to collapse straight down (not 'collapse easily', that would be a different and dangerous thing).
1. Costing less in its required demolition force,
2. Costing less in the debris removal by rendering the rubble pulverized through axial inertia, and
3. Making it less of a hazard (magnifier) to adjacent buildings in the case of an earthquake, fire or bomb calamity.
That would involve specific targeted vertical columns which achieve the quickest and most even dynamic load (not static load) re-distribution; and which would have clearly flagged 'critical structures' which are to be blown in a forced implosion. Each column would need to be designed to collapse a certain way, and when they are all brought into synchrony, cause the building to free fall in a vertical axis.
Now I am not a building code expert. But that is what I would do.
But to pre-plant the explosive charges would be an insurers nightmare (Factory Mutual, Travelers, etc). Because no matter what happened, a victim could always claim that their family member's demise occurred because charges were placed in the building, and caused its premature collapse in a run of the mill trash can fire. :D
