1. The main work contents and responsibilities of each official are as follows: 1. Quality inspector: mainly responsible for the supervision and inspection of project quality; 2. The builder: mainly responsible for leading the operation team to construct according to the drawings; 3. Supervision: it is the responsibility of supervision and the post established by the supervision unit; 4. Surveyor: mainly responsible for engineering positioning and setting out; 5. Material clerk: mainly responsible for the supply and management of materials; 6. Safety officer: mainly responsible for the specific safety management of the construction site. Second, considering the above situation and your future career development, I think supervisors and quality inspectors are most beneficial to your work. The reasons are as follows: Of the six members of 1, the builder is the hardest. It should be closely combined with the construction team, reasonably control manpower and material resources, and implement the graphic content into the project entity. The content of this job determines its hard work. But it has its advantages, one is that it has little responsibility, and the other is that it can be deeply familiar with the specific construction technology. The fattest job among the six senior officials is the material clerk. Needless to say, everyone understands this, but it is difficult for people who are not leaders to simply intervene. Although this job is of great help to your future major, I'm afraid you won't find a suitable place to use this certificate. The most responsible safety officer among the six officials is very concerned about the current domestic construction safety, but the domestic construction situation is very chaotic. Formal management is rarely implemented, and safety accidents are common. You are the first person to have problems, and you don't meet your major, so this member is definitely not needed! 4. Surveyor's work is monotonous, and you can't learn anything useful in the work, which will not make any contribution to your career development. The first few years after graduation are the time for you to increase your ability and experience, and it is a waste of good years to engage in surveying and mapping. 5. The responsibility of the quality inspector is heavier than that of the builder, but the work intensity is inferior to that of the builder. Therefore, this position in the construction unit is an ideal position. First of all, the work intensity is low. Secondly, it has a certain status because it has a certain authority. Thirdly, similar to the builder, you can also learn some specific construction techniques, and you can also take time to strengthen your study. So, if you want to work in a construction company, then this position should be said. 6, supervision is different from the other five members, it is usually not the construction unit but the position of the supervision unit, its angle determines the superiority of his position, and it will not be as hard as the construction unit, the key is that it has enough time for you to learn, which is very beneficial for you to take the registered cost engineer in the future! This position is the most helpful position for your major among all the above positions, because the supervisor is a combination of technology and management. In this position, you can not only get in touch with the construction technology, but also get in touch with other comprehensive knowledge such as project cost, schedule and contract management, which is very beneficial to the cost specialty, because the cost is a specialty integrating engineering technology, engineering economy and engineering law, so it can be said that the supervision position should be your best choice at present. To sum up, from the perspective of your future professional development, try to promote the supervisor; If you don't have the opportunity to go to the supervision unit, then you should choose the quality inspector of the construction unit.
