let's be clear here about some things.
A), i am not saying it was foul play.
i'm just saying they way too prematurely dismissed that possibility, and basically did so before any investigation of any kind could be done on anything..
it was basically as if that declaration was done for political/economic reasons, rather than anything objective.
seems like they pretty much did so almost before news crews got to the scene..
B), you are merely stating that it hypothetically could have been from pool water, just as i have been saying it hypothetically could have been foul play, and neither of us has proven anything, and only stated hypotheticals.
that said, unlike in your hypothesis, i believe the ground under the deck had been excavated all the way to the pool itself, and the basement floor level under the deck was the same level as the parking areas. (see above pic)..
i've also read accounts that the parking garage extended to the pool itself, with pics of said wall, though no idea the accuracy of that.
as for the pool room, while i know nothing about pool rooms, i would suppose it to be adjacent to the pool itself, and likely sharing a wall with the pool.
point being, i think a good chance the pool room itself would be removed from being directly under the building, and question how close the closest wall of the pool room comes to infringing on the support of the building itself..
that said, a decent percent of the zillion 100 plus yr old homes in the country have basements that get some water in them with every hard rain.
and 100% of them get some level of soaked ground water surrounding basement outside walls that comprise the foundation with every hard rain, and for a portion of every spring.
------------------------------------
as to "tenants hearing creaking sounds the day before", i think that is obviously as relevant and disconcerting as anything you posted, and i hadn't heard that before.
that said, i wonder if this was a first time thing, or if that was somewhat common in this complex, or for that matter, many to most to all complexes.
or was this creaking, or level of, different from any norm in this building?
every house i've ever lived in often had creaking sounds from expansion/contraction with a large temp change, and though i can't say i noticed them as much in apts i lived in, perhaps i just noticed them less there.
never the less, if these sounds were out of the ordinary, that is significant.
as for the sound of a bomb.
A), a bomb centered in parking garage would be significantly muffled outside the garage just due to it's location.
would it still be audible, no doubt, but not nearly what a bomb on the street would be.
B) while zero expertise here, i'll hypothesize unlike in a controlled demo where many explosives are used to disrupt the structural integrity in many places, leading to a slightly delayed collapse of the structure, if a truck bomb or bombs totally took out multiple support columns, as in Ok City, would the ensuing collapse perhaps not come more immediately than in a controlled demo?? (thus at least complicating differentiating the sound of the bomb and the collapse itself).
no one in the collapsed structure is here to give us their accounts.
as for the residents in the non collapsed part of the structure, i can't comment on how much they could differentiate the sound of the bomb from the collapse itself, if almost immediately ensuing, and again, taking in consideration the parking garage location and that many would be asleep at the time.
---------------------------------------
as for the bomb dogs thing, i find that far more than just very interesting.
very hard to believe they didn't have bomb dogs there by the next morning, more likely that night, and if so, why no reports as to such, or how that went, either way???????????????
if bomb dogs were not there that night or by the next day at least, how questionable as to really wanting answers is that??
if no bomb dogs there by now, well over a month removed, how telling would that be as to looking for a cause??
and if there were bomb dogs there by now, would we not have heard of this either way that went??
we absolutely would have.
kinda like in commercial plane crashes, no doubt they would love a way to find human error as the cause for money reasons.
if it's some concrete/rebar issue, the economic repercussions would be huge on every multifloor structure in the country, even if just from an inspection and maintenance perspective..
if foul play, the repercussions on every structure with a bottom level parking garage would be huge.
even if it's a maintenance and upkeep issue found, the economic repercussions would be huge.
that said, unless they find evidence of a bomb or foul play, i question if anything other than a "possible" cause will be found.
i think Wall St, the real estate, and the entire high rise MDU universe, would all love this thing to all just go away quietly into the night.
and understandably so.
if we allow that, how irresponsible are we?
and even if foul play is only a 5 or 10 or 15% chance, (let alone higher, which i'd think is possible if not probable), to not vigorously pursue and investigate that even possibility, regardless of how remote or high, which we know not, would be just walking away from the possible mass murder of approx 150 people for economic expedience.
as for the amount of push back from even the suggestion of the possibility of foul play, hard not to find that interesting in of itself.
