Terrible logic/incident relationship.

I don't disagree, but water incidents can happen anywhere, anytime and SUCK.

Yes, it most definitely can happen anywhere. But the impact and size of damages are far less when you have a shorter building.
 
I've had some insurance reviews after water breaks in shorter towers. If not caught quickly they still add up. Had one pex line that cracked. was more than 2 mill damage when found.

However depending on what broke could add to the cost, especially if it was a glycol line. But I seem to remember the most above 28 is cooling plant and domestic water storage. If it was a feed for the upper mech room on 69 then we have a large volume.

Pex is susceptible to cracking?

it is particularly sensitive to sunlight/UV with potential exposure and deterioration pre as well as post construction; to various chlorine/chloraminr solutions (particularly at higher concentrations and moreso in combination with hot water); to repeated exposure to freezing; and joints are susceptible to damage from “water hammering”.

I don’t know if that qualifies PEX as being “susceptible to cracking” but it certainly isn’t immune to cracking.

Yes it does crack. There was a service bulletin out some years back as well as a lawsuit or 2. The other, Aqatherm piping is also susceptible. They both have to be installed at specific temperatures. I only found this out when we were lookin at why we had some failures on some systems a few years later. PEX did change the chemistry to deal with some of the issues, but if the installers do not follow procedures things happen.
 
Thanks @Airboy this aligns with a recent restaurant I was involved with on the Design side of things. The owner hired a lawyer to sue and of course I got involved. A hot water line (PEX) split near the under-counter shut off valve. I took pictures and forwarded same to the owner's lawyer -- the plumber installed the line with a hard bend and -- fortunately -- I forewarned the plumber before the Final Inspection, suggesting (in writing) that there could be future problems. When a leak developed the plumber blamed it on PEX whereas the owner looked for proof of a poor installation. I have since been collecting (where I can) others' experiences. I have not lost faith in PEX -- I believe that it is still superior to copper if installed correctly and it is certainly an easier install from a labor perspective. I wonder what the issue was for Stantec tower.
 
Cleaning up some old pics/screen shots and came across this one.

Many sites don't allow for the distribution of photos unless approved by the GC. These were IW 720 guys, and while I've worked around some and found them to be great at their jobs, the consideration of GC feelings has never been a major concern of the older workers.

My feelings on this photo are the same as the 720 guys. If the people in the office don't like it, walk the steel and take the picture yourself. The photo is gonna happen no matter what when a building like this tops out.
 
It was also a PCL job, who are notoriously strict and controlling on their project sites (for good reason). Piss in the wrong direction without approval from the super and you'll be skidded off site 🤣
