Legally speaking:

1. No matter what your professional title is, your unit is not a design department, and you have no design qualifications. Since the drawings were not produced by a legal design unit and approved by relevant departments, this building is not a legal building and should be illegal.

2. If the drawings you produce are not signed by yourself, you will not be held legally responsible.

3. There is a problem that requires your attention. Once a big problem occurs in such a building, the chief engineer, boss, and even relevant departments will have to shirk responsibility. Will it be pushed to you? This is true in some places today. It's really hard to say whether it will be resolved by law.

Also:

After reading your supplementary answer, I am really worried for you. This is a serious act of cutting corners. At the beginning, I thought you were just designing and not signing. If something goes wrong, your responsibility might be smaller. But you said that cutting is also your job. Although the drawings are not signed, you drew them, and when you cut the materials, the material specifications are smaller than those required by the drawings you drew, then it is serious. If other projects do not collapse after they are built, it does not necessarily mean there are no problems. Normal design has safety reserves, such as earthquake resistance.

If there is a real problem, the boss will push it six, two, five, and you will not be able to explain it clearly. Seriously, this could be a matter of life and death.

It is very difficult to find a job now, so I can’t give you any other advice. Please weigh the pros and cons and make a decision for your future. To be honest, I would not dare to stay in such a company.

More:

From your questions and supplementary questions, it can be seen that you are not deeply involved in the world and have some concerns about the problem. I suggest you think more about your personal responsibility and then your professional conscience. Didn’t the Wenchuan earthquake explain the problem? Of course, natural disasters are the main reason. If an accident does occur due to design or manufacturing defects, even if you are not held responsible, as an insider, whether you can feel at ease is your personal problem. Please forgive me for offending.
