Who would have thought that drilling for pilings adjacent the sinking sides would accelerate the sink?

I thought that SF was the epicenter of “follow the science”. Maybe I missed it that “science” is now an alias for media.

I have become painfully convinced over the years that Mother Nature is tricksy and false. Natural environments are difficult to model and quantify. My Koi pond sank into the hard blue clay subsoil in my backyard more than I guessed it would, about 6 inches. It caused me to repair and modify plumbing and adjacent plantings. Maybe that sinking had something to do with supporting 45 tons of basalt and 5,000 gallons of water (=40,000lbs), all in a rainy locale. Good news is that it’s stabilized now, after about 12 years since we enlarged it so much. Used to be about 600 gallons and maybe 5 tons of rock.

I watched the whole series he put out. The real scandal is that the Old Bay Clay under the original friction pilings can’t carry the load, and never could. Computable without resort to FEA or other modern tech.

I think the architect of The Learning Tower of San Francisco deserves Reparations from Mother Nature.
Let’s go shake her down.

How could any rational actors expect stability of any substrate in a jurisdiction were “female” cannot be defined, is a varying number of genders by fiat, 2+2 may be 5, crime is solely defined by non-adherence to the latest woke nostrum, truth is a matter of revelation to self-described supremacists (easily identifiable by their amplified hatred of those they complain are “supremacists”). In other words, don’t expect any structure to remain stable in thoroughly unstable California. Just sayin’ (the obvious).

Heh. It struck me that the HOA’s approach to the foundation problem is to declare it isn’t a problem “because we say so”. And claims that subsidence is bad for the building is just biased egghead nonsense.
