How much quantity does municipal engineering have to complete before the project manager can be dismissed?

Two conditions must be met to dismiss the project manager. One is to complete all the construction tasks and pass the completion acceptance, and the other is to complete the follow-up work after the project acceptance, including the completion filing, file transfer, completion settlement data and settlement procedures, and project summary. Generally speaking, the project manager can basically complete the above work within 3 months after the project is completed, and then he can cancel it.
