Invite experts in this field of bidding agency.

I have been a bidding agent for two years. There are not many people in this company, but they are all private enterprises anyway. If you just graduated and want to learn about budget, first check whether there are experienced cost engineers in your company. Whether this kind of company is reliable or not depends on your boss's character! If your company has the ability to make budget, it is more comprehensive to learn budget in bidding company than in construction company. Bidding, engineering, greening, roads, etc. Very comprehensive.
