At the time of application for tap-on permit, the owner, contractor or other applicant shall advise the City Engineer of the probable time when excavation and sewer construction will be commenced. Before the sewer or any portion thereof shall be covered, it shall be the owner, contractor or other applicant’s duty to give the City Engineer notice that the same is ready for physical inspection. In the event that any such sewer or any portion thereof is covered without such physical inspection, the City Engineer may order the same uncovered at applicant’s expense for purposes of inspection.
