How does a sinking high rise manage mains connections?

[geoffhazel]

The Millenium Tower, a 58 story high rise built in 2009 in San Francisco has sunk 16" in the last 8 years. I'm wondering how the water and sewer is connected or dealt with when the entire buiding (but, I would assume, not the surrounding utility pipes) sinks 16"?

Here's just one article talking about it: http://www.constructioncitizen.com/blog/leaning-tower-san-francisco-looks-it/1609021

I'm just guessing but seismic plates are common in high rise buildings in California, and many are set on rollers. It would seem that all utilities are set up with flexible connections to provide "give" when the seismic plates are used.

The part is called a flex tend. We use them on occasion. It let's tge pipes move and shift without breaking although 16 inches is quite a bit. I'm thinking they have done some repairs

I have done a fair share of work in Louisiana, Their, the clay swells and contracts so bad

it is code to tie the pipes with SS wire to the foundation,

so when the ground moves the pipe will stay in place. ''theoretically''

No that is not code and i have never heard of that. use gravel instead of sand and u will be just ok

if you use gravel with out ss ties, you will be red tagged
