Others work in design, construction, research and teaching. They work with others on projects and may be assisted by civil engineering technicians and technologists. Different levels of government employ civil engineers to perform much of the same tasks as those performed in private industry, except that civil engineers employed by the government may also inspect projects to ensure that they comply with the regulation. Civil engineers generally work inside offices. However, they sometimes spend time outside on construction sites so they can monitor operations or troubleshoot problems on the job site. Sometimes civil engineers travel overseas to work on large engineering projects in other countries. Civil engineering is a very demanding but rewarding career because the engineer is able to work on a project from its inception to its completion. When you cross a bridge, see a building, leave an airport or visit a museum, a civil engineer has played a major role in doing so.
