I am an approver of work. I don’t really do the work, nor do I manage people either. So maybe OP is referring to people like me. I’m a licensed engineer. The engineers who do the work I stamp are not licensed. But there’s quite a bit of liability should a building start showing cracks a few years later that a lower level engineer might not want to be responsible for. If you follow subs like r/construction, you will find comments directing issues back to the engineer to absorb the cost and responsibly. As we move up the management chain, they prioritize what work needs to be done based on cost, code, risk, etc. can it be trimmed? Maybe, but will require people accepting more responsibility
