An interesting tidbit, blending geotechnical engineering with the arts community. Seems that the politicians chose a new site based on political optics. Had a big party already! Too bad the site is all water-logged mud.
You can actually build on a site like this, if the bedrock is at a reasonable depth, and you use piles or caissons. But you can't put in an underground parking structure! Much like the sites that politicians choose for nuclear plants, the local geology doubles the cost.
