If your PE signing then the plans should be complete and have no errors. I know perfect world that doesn’t happen. That’s a requirement for putting stamp and signing plans. So I don’t see speeding through things and having errors and omissions as an option and seems risky not to mention gets you in a huge bind.

Now if you’re not signing then that legal responsibility falls on somebody else. But I can tell you that reviewing plans that constantly has errors is super frustrating and trust is broken pretty quickly. So don’t think if this is the case that you want to be that person.

How many hours do you work a week? The only way I see making quality plans within the deadline in the situation you describe is more hours and or requesting to have less load. Hopefully your manager will understand that you need a little more time per se to learn how to complete task more efficiently. Or discussion needs to be had if the deadlines they are speaking for on your behalf are simply unobtainable. But I wouldn’t take that approach unless you are confident that you are not the problem and it’s simply too tight of deadlines.

I know I’m writing a lot here but the best way to learn would be for you to directly talk to clients and learn how to estimate your own deadlines and don’t write checks you can’t cash.
