When the purpose for which the opening or excavation was made has been accomplished and in no event later than the expiration of the time limit specified therefor in such permit, the person to whom such permit was issued shall notify the Service-Safety Director that the opening or excavation is ready to be closed. Thereupon, the Director shall cause the opening or excavation to be backfilled, refilled, tamped and resurfaced, in accordance with the engineering and construction practices hereinafter set forth in this chapter, in such manner as, in his judgment, will preserve and prevent subsidence in the surface of such street, alley or place. For such purpose the Director may employ such helpers as may be necessary.
