Besides being talented civil engineers, Civil Supervisors must possess leadership skills so people will stay on task and work hard to get things done. They also must be outstanding organizers capable of working within budget and time constraints. Civil Supervisors monitor civil construction projects. They oversee activities such as building bridges, repairing highways and doing construction on airports. While Civil Supervisors may have an office, much of their time is spent on construction sites to make sure all parties involved are performing up to par.
