Less than 10 year old, 25 story McGuire PT building in Seattle that was demolished back in 2010 ...
(OP)
I recall the 'shenanigans' of the McGuire apartment building in Seattle back in 2010 (Link 1 and Link 2). Summary ==> 9 yo, 25 level PT building that had some strand corrosion issues at tendon ends due to water/moisture penetration from live-end grout pockets...fast forward to 2010/11 and it was demolished! I don't recall if it was discussed here at Eng-Tips at the time.
Well I just read this report Link3 by Bondy, Poston et. al, and whilst the authors do not mention the McGuire building by name (to protect the innocent/guilty?) it is obvious it is indeed the project they refer.
Always interesting in getting the 'other side' of the opinion.

I have seen some totally screwed up UNbonded PT structures (with massive tendon blowouts and spalls, some with deflections that were of magnitude of 50% of the slab depth, others with 75% of the tendons corroded in a single band etc etc) but they were usually 25+ years old and they were repairable - economically repaired (but not cheap) compared to demolition. Certainly seems like a drastic step to tear it down.
One engineering side treats it like terminal cancer and the other engineering side takes a totally different rationale - and the lawyers win regardless!

The owner's intend to re-build, however, I am not sure if they are/have to date.
Seattle Times link of above quote.
I am not sure how the owner's "...engineering firm concluded that cables will likely start breaking next year and about one-third would fail by 2019", but I do know we shall never know, in this instance!

Hard for me to comprehend that this resulted in a 25 story building being demolished.
