I used to do field work, but now I do budget. I don't know how to learn now, and there is no master to take me.

I said: it's not bad to learn mechanical engineering and make a steel structure budget now. There is a certain foundation, such as understanding drawings and some materials and equipment. Next,

1. You can attend the training class, learn some knowledge about budget work through study, and then obtain the qualification certificate of cost engineer.

2. Look at the quota, understand the quota description, measurement rules, and the composition and content of the quota subtitle;

3. Look at the completed budget book (simple) and learn: know and understand the concept and process of budget work;

4. Seriously study the problems you don't understand. If you really don't understand, ask someone else;

5. Start budgeting, start with simplicity, imitate cats and draw tigers, think seriously, consult modestly, constantly sum up, analyze and improve.
