A competent person is responsible for making daily inspections of excavations, including the surrounding areas and protective systems

I believe the answer is: Daily

During the previous excavation, the safety measurement that the team made prior to the excavation may be compromised due to the movement and the vibration force made during the excavation .

Because of this, a competent person must be appointed to inspect it daily in order to prevent future accidents.
