Can architecture majors apply for the first-level construction engineer qualification for water conservancy and hydropower?

You can definitely apply. The application conditions for the first-class construction engineer issued by the Ministry of Housing and Urban-Rural Development clearly stipulate that those with a college degree or above in engineering majors, who have been engaged in construction and related work for six years or more, and who have completed a bachelor's degree of four years can apply. Isn’t the architecture major an out-and-out engineering major? The scope of engineering is very wide, and you can apply for it as long as you are in engineering. This is the basic application threshold. Of course, there are ten majors in the first university. Candidates can choose one of the majors according to their work needs and their own strengths. Ten majors: construction engineering, highway engineering, railway engineering, civil aviation airport engineering, port and waterway engineering, water conservancy and hydropower engineering, municipal public engineering, communications and radio and television engineering, mining engineering, and mechanical and electrical engineering.
