A site engineer is an on-site construction consultant who provides advice about technical aspects of a civil engineering project, such as building a highway or bridge. In this career, your job duties include traveling to construction sites to determine the site’s environmental and physical quality, determining what types of technical difficulties the project may encounter, and making recommendations on how to avoid them. You often prepare reports for developers, contractors, and other construction professionals, outlining your advice. You may also provide managerial support on-site.
