Underground Heat Is Shifting Chicago’s Foundations

In many places foundations are not sunk to bedrock, rock is far too deep to reach. Instead the pilings use friction to maintain their position.

What places besides the mess in SF ? (I'm not sure how to search such a query, but super interesting)

Bedrock is very deep in Seattle. You can see the map here: https://pubs.usgs.gov/mf/1692/plate-1.pdf

For instance the space needle is just on a giant hunk of concrete that is only 30ft deep. https://www.spaceneedle.com/history#:~:text=An%20underground....

But from memory most large buildings in the downtown area are on deep foundations in soils, not to bedrock.
