Civil engineering, whether it is roads, bridges, or buildings, is the profession most qualified to become a structural engineer.

One year of civil engineering graduates can take the first-level registered structural engineer basic examination, two years after graduation, they can take the second-level structural professional examination. Four years after passing the first-level registered structural engineer's basic examination, they can take the first-level structural professional examination.

After passing the exam, you can become a structural engineer, and you can register and practice.

The first-level structural engineer has basic exams and professional exams. The second-level structural engineer only has professional exams. The scores are valid at one time. The basic exams of the exams are closed. The professional exams are open. You can bring specifications and personal notes and information.

Refers to obtaining the qualification certificate and registration certificate of a registered structural engineer of the People's Republic of China, engaged in structural engineering design; technical consulting for structural engineering design; investigation and appraisal of buildings, structures, engineering facilities, etc .; construction guidance and supervision of the project that I presided over the design ; Other businesses as stipulated by the Ministry of Construction and relevant departments of the State Council. Among them, the scope of practice of the first-level registered structural engineer is not limited by the scale and complexity of the project, and the scope of practice of the second-level registered structural engineer is limited to the third-level project of civil engineering grade classification standards prescribed by the state.

In the main documents (drawings) of the structural engineer's design, in addition to indicating the qualification of the design unit and the official seal of the unit, the registered structural engineer in charge of the design must be signed at the lower right corner of the structural design drawing and stamped with its special purpose Chapter, side is effective. Otherwise, the design review department will not review, the construction unit shall not apply for construction, and the construction unit shall not permit construction.

The scope of practice of registered structural engineer:

(1) Structural engineering design; (2) Structural engineering design technical consultation; (3) Investigation and appraisal of buildings, structures, engineering facilities, etc .; (4) Construction guidance and supervision of the project designed by me; (5) Construction Other businesses stipulated by the Ministry and the relevant departments of the State Council.

The scope of survey and design of a registered engineer is not limited by the scale of the project and the complexity of the project. The survey and design scope of the second-level registered engineer is limited to undertake civil engineering projects of level three and below or small industrial projects as required by the state.

In summary: Structural engineers are structural design and research in the civil construction industry, excluding architectural design and mechanical design.
