I am a small supervisor, and the leader asked me to sign the station record of deep foundation pit excavation, and also asked me to sign it.
You can't sign this. The duty of the supervisor is to be responsible for the supervision and inspection of the project quality and the completion acceptance of the project quality. If you sign it, you will be in big trouble in the future. Therefore, for the unqualified and jerry-built project quality, you should report to the superior leader of the unit in time to urge the construction party to rework.
