Starting at 17:45 in this October, 2010 video provided by the CTBUH, Jim Loewenberg and Bruce Lake discuss the economics of caissons (among other factors) for buildings taller than 55 stories. They both concur it could possibly be as late as 2020 before a residential tower requiring rock caissons (which they report cost 10 fold that of bell hardpan caissons) is built.
