The infamous Eastern Michigan University water tower...

A pair of cracked windows have been discovered at San Francisco’s Salesforce Tower. It’s another stroke of bad luck for the city’s newest architectural marvels.
The San Francisco Chronicle reported that local Department of Building Inspection officials confirmed the presence of cracked window panes in the 61-story, Pelli Clarke Pelli-designed tower last week. The cracks were discovered along the inner panes of a dual-glazed, south-facing window on the 12th floor and a similar east-facing window on the 14th floor of the tower.
A spokesperson for the building’s owner told CBS in San Francisco that because the cracks are located on the inside of the window assembly, the damage poses no danger of falling glass. The cause for the cracks has not been discovered, but plans are underway to replace the affected windows in the coming weeks.
The Salesforce Tower opened in January 2018 and is currently San Francisco’s tallest building. At 1,070 feet in height, the building is considered the second tallest structure in the western United States behind Los Angeles’s Wilshire Grand tower.
The discovery of cracked windows at Salesforce comes months after broken window panes were discovered in the Handel Architects-designed Millennium Tower just one block over. The 58-story tower has settled over 18 inches on one side and is also leaning by 14 inches, according to recent reports.(snip)
Another new San Francisco project, the Transbay Transit Center, located at the base of the Salesforce Tower, remains closed nearly six months after a pair of cracked structural beams were discovered in that building. A permanent fix for the damaged beams is currently underway, though a reopening date for the transit center has yet to be announced.

Chinese-made glass? And maybe Chinese-made glass that is labelled “tempered”, but really isn’t tempered at all.
It’s bert’s fault
A transparent attempt at window glass humor. :)
You saw right through me!..................
Hahahahahahaha!
The infamous Eastern Michigan University water tower...
Is the building settling? Lots of loose ground around there, from thousands of years of quakes and building on fill.
The problem is that the area of SF where these buildings are located are actually where they filled in over the rotting ships that brought the gold miners here in 1849. They talk about “bedrock,” there isn’t any unless you go way, way down. When they excavated for BART years ago, it was like digging in an Indian burial ground.
The legend is, is that when a virgin graduates from Eastern, the tower will topple.

One can see through this humorous attempt
Grew up in Palo Alto. Visiting SF was always exciting at any age. My two sons left CA at a young age but took them back to SF once, had lunch at the Cliff House and the next day dinner at Alioto's and that was it, headed for Yosemite and then North Star. SF has been a heart-breaker for several decades.

"There was shrinkage."
As far as I know, the Salesforce Tower building is anchored to bedrock and probably not at any risk of collapsing. The Millennium Tower is the one they cut corners on, and even if it doesn't collapse in a big quake it might need to be taken down as a safety precaution.
Las Vegas made MGM completely dismantle the Harmon Tower on the Strip after it was complete due to the discovery of construction defects. There is precedent for removing faulty high-rises: Harmon Hotel Demolition.
I dislike the current trend of skyscrapers being a sort of vertically-oriented amorphous blob. There’s no compelling functional reason for it and the aesthetics are not great either, they’re just doing it because they can. That building will look horribly dated in a decade, like all those pink granite towers from the 80’s did.
Not a problem. Just have the super-genius Elon Musk dude go over there and do some of his tunnelly majick and put a few bags of concrete in the strategic places. After all, its just another engineering problem. /s
You are almost exactly correct. “Fracture” is the correct word and full-tempered (FT) is a common interior glass lite of high rise due to safety codes whereas the exterior lite of a dual glaze is commonly heat strengthened not FT. In this building however the interior nomination is actually a laminated lite of 2 glasses 1 HS and 1 FT so it is entirely likely that the HS is the lite to have “cracked” not the FT. HS can and will break for various reasons and edge compression is one of them. the entire unit however of the IGU assembly is captured to the framing system with a unitized set so the unit must be cut out of the framing it will not “fall out”.

Developable land in the biz district is very pricey and unavailable so there is that factor in building vertical
