During the course of construction and prior to the issuance of a certificate of completion for a public improvement under this Chapter, the City Engineer will inspect the improvement and determine if the various kinds of work performed are in compliance with the plans, specifications and allowances of the permit as to quality of workmanship. Furthermore, the City Engineer will check the improvement for alignment, proper computation of quantities and conformance with the established grade. If all of the work required is completed and done to the satisfaction of the City Engineer, the City Administrator will give a certificate to that effect. The City Administrator may state that the improvement is accepted, if done within the completion date, as set forth above, and within recorded public right-of-way and easements. Otherwise, the acceptance may be made by the City Administrator on the certification of conformity to Code provisions and proper grades filed by the City Engineer.
