Can the supervisor supervise the construction unit before the formal commencement (that is, the commencement report of the construction unit)?

If the supervision unit is wrong, it must be executed according to the contract. If the supervision contract includes the exploration or feasibility analysis stage in the early stage of construction, even the supervision of the exploration and feasibility analysis stage can be carried out. Generally speaking, the current supervision only starts from the construction stage. Of course, the construction stage here includes the preparation stage before construction. The submission of the commencement report shall be supervised by the supervision unit according to the requirements of the supervision specification. Judging from the supervisor's behavior, the supervisor either deliberately evaded responsibility or didn't understand it, so he should have doubts about his supervisory ability.
