nope: procurement cheapskates!

hydrogen introduced during manufacture or corrosion appears to be main causes, the buildings new so I'm going for cheap untested hardware and procurement that thinks a bolt is a bolt.

One has to save somewhere, after paying those fees to contractors ....

Hydrogen embrittlement

Coming soon...

" British Land has revealed that another steel bolt on the Cheesegrater skyscraper has broken, bringing the total to three.

The real estate group said the third broken bolt was caught by "precautionary tethering" put in place last year.

It did not disclose when the bolt fractured, saying only that the incident occurred "recently".

In November, two steel bolts broke on the 737ft skyscraper just days apart, with one plummeting to the ground at the side of the building.

Nobody was hurt since it landed in an area that was already cordoned off for construction. But the bolts are roughly the size of a human arm and the 47-storey landmark was cordoned off from pedestrians while the incident was investigated"
