People who have worked in engineering cost for several years want to change careers. What should they do?

How thoughtful of you, my friend! If your hypothetical situation really appears, it must be that the whole construction industry is in recession. So your hypothetical environment and career planning can only jump out of the general environment of the construction industry. Compared with other architectural specialties, cost is a multidisciplinary specialty. In fact, as long as you have consulted the cost engineer, the economic aspect has already begun. Turning to economic work is the main path of cost specialty. Financial accounting or asset evaluation can be considered. These two majors are not lazy in any single industry, with strong anti-risk ability and considerable income. I hope I can help you!
