That would make the most sense but the construction unions in New York have a peculiar agreement that the concrete workers cannot work ahead of the steel workers. So you will not see a concrete core rise ahead of the steel even though that is the schedule used in almost anyplace else in the world. BOFA and 7 WTC also have concrete cores that were never visible throughout anypoint of the construction process.
