I am still amazed that so far no one has gone to jail for this. In SF’s building permit department specifically.
Someone signed off on this spectacularly poorly-thought-out variance from all known skyscraper construction principles.
Everywhere else: you better sink those supports into the bedrock.
This case: I’m sure a half-assed group of pylons in reclaimed sea silt for one of SF’s biggest buildings ever will be just fine.
