You using industry or occupational data? Not clear from your post. Obviously skilled construction workers are different from all construction workers in the aggregate -- did you purposefully mean to collapse this distinction?
BLS's May 2007 OES finds for the NYC-White Plains Metro Division a mean annual income of $75.6k for operating engineers, electricians $70.2k, iron and steel workers $72.4k, elevator installers $69.6k, first line supervisors $80.9k. See:
