Job Bank's national median is $48.72 an hour, about $101,000 a year full time. Job Bank files general contractors under construction managers, which includes salaried site superintendents and project managers. Self-employed contractors sit anywhere from a loss in a bad year to well above the top figure when the company is busy and the margins hold.
