Do you know how to tell others in English what engineers and civil engineers do?

So, here:

Engineers apply scientific and mathematical principles to develop economic solutions to technical problems. Their job is to perceive the connection between social needs and commercial applications.

Engineers will consider many factors when developing new products. For example, when developing an industrial robot, engineers accurately specified the functional requirements; Design and test robot parts; Integrate components to produce the final design; And evaluate the "overall effectiveness, cost, reliability and safety" of the design. This process is applied to the development of many different products, such as chemicals, computers, gas turbines, helicopters and toys.

In addition to design and development, many engineers are also engaged in testing, production or maintenance. These engineers supervise the production of the factory, determine the causes of component failures, and test the manufactured products to maintain quality. They also estimate the time and cost of completing the project. Some people enter the field of project management or sales. In sales, the engineering background enables them to discuss technical aspects and assist in product planning, installation and use. The supervision engineer is responsible for the main components or the whole project.

Civil engineers design and supervise the construction of roads, buildings, airports, tunnels, dams, bridges, water supply and sewage systems. They must consider many factors in the design process, from the construction cost and life expectancy of the project to government regulations and potential environmental hazards, such as earthquakes. Civil engineering is considered as one of the oldest engineering disciplines, including many specialties. The main majors are structure, water resources, architecture, environment, transportation and geotechnical engineering. Many civil engineers hold supervisory or management positions, ranging from supervisors on construction sites to municipal engineers. Others may be engaged in design, architecture, research and teaching.
