  In a 2009 article describing the collapsing Dubai economy, The New York Times reported that the Palm was sinking and this has been confirmed now by geological surveys, at the moment it is 5 millimetres (0.20 in) per year but this could increase rapidly. I'm sure they have all the cash in the world to make it look like this isn't the case but there's only so much that engineers can do to reverse the laws of nature.

    You can float buildings on sand/marshland. It costs more, but the buildings are vary stable.

  I think it's more about the literal action of building on sand. It erodes quickly and hence requires upkeep (dredging from where it flows to, and restocking where it flows from). Sand also has a nasty habit of liquefying during earthquakes, destroying buildings at their very roots. Although the Korean peninsula as a whole isn't at too great a risk of tremors[0], it's still a risk that they're taking.
