1164.03 CONSTRUCTION, IMPROVEMENT PLANS AND SPECIFICATIONS.
   Drawings showing plans, cross sections, profiles, elevations, typical sections, construction details, and specifications for all required improvements shall be prepared by a professional engineer. The improvement plans shall be prepared in accordance with the standards set forth in Chapter 1166 and subject to the terms and conditions of regulations.
   If it becomes necessary to modify the improvements as approved due to unforeseen circumstances, the subdivider shall inform the City Engineer in writing of the conditions requiring the modifications. Written authorization from the Commission, upon approval by the City Engineer, to make the required modification, must be received before proceeding with the construction of the improvement.   
   At completion of the construction, and before acceptance, the subdivider shall furnish the City Engineer a set of reproducible mylar drawings (excluding sepia) for permanent record, showing the locations, sizes, and elevations of improvements as constructed, and shall provide AutoCAD drawings of the entire project containing the as-built information as well.
   (a)   Preconstruction Meeting and Work Schedules. Prior to the commencement of any construction the subdivider shall notify, in writing, the Safety-Service Director, all utilities, the Stark Soil and Water Conservation District, and the City Engineer of the date of commencement of construction. A preconstruction meeting shall be required with regard to procedure, materials, and inspection of the project.
   (b)   Construction Inspections.
      (i)   Responsible Official. The City Engineer shall be responsible for the inspection of all street improvements including storm sewers, water lines, sanitary sewers, and sanitary treatment plants and appurtenances.
      (ii)   Authority and Duties of Inspectors. Inspectors employed by the City shall be authorized to inspect all work done and all materials furnished. Such inspection may extend to all or any part of the work and to the preparation, fabrication or manufacture of the materials to be used. The inspector shall not be authorized to revoke, alter or waive any requirements of the specifications or plans. The inspector shall be authorized to call the attention of the contractor to any failure of the work or materials to conform to the specifications and contract. The inspector shall have the authority to reject materials which do not meet specification requirements or suspend the portion of the work involved until any question at issue can be referred to and decided by the City Engineer.
      (iii)   Final Inspection. Upon completion of all the improvements, the subdivider shall request in writing a final inspection by the City. The City Engineer shall make a final inspection of all streets, storm sewers, water lines, and sanitary sewers. Inspections shall be made promptly after the request is made.
      (iv)   Before any roads developed as part of a subdivision become public, the City Engineer shall first inspect such roads and certify his approval.
      (v)   The developer should have his representative present at the time of all inspections.
   (c)   Construction Responsibilities.
      (i)   Cooperation of Subdivider and/or Contractor. The subdivider and/or contractor shall have available on the project, at all times, a clearly readable copy of all required plans and specifications. He shall cooperate with the inspector and with other contractors in every way possible. The subdivider and/or contractor shall have a competent representative or superintendent acting as his agent on the project. The superintendent shall be capable of reading and thoroughly understanding the plans and specifications, and he shall receive instructions from the inspector. The superintendent shall have full authority to execute the orders or directions of the inspector and to promptly supply such materials, tools, plans, equipment, and labor as may be required. The inspector’s orders should be executed without delay. A superintendent shall be furnished irrespective of the amount of work sublet.
      (ii)   Grade stakes. Pavement and pipe grade stakes shall be set at 25 foot intervals on horizontal and vertical curves and for all grades less than one percent. Tangent pavement grades and pipe grades over one percent may be set at a maximum interval of 50 feet. The inspector may ask for additional grade stakes if it is deemed necessary. Other means of line and grade may be used as approved by the City Engineer.
      (iii)   Repair of Damage. Any damage done to the improvements by construction traffic, local traffic, or by any other means shall be repaired or the damaged materials replaced in a satisfactory condition.
      (iv)   Erosion Control. The subdivider and/or contractor shall take necessary procedures to prevent soil erosion and downwash of grits and sediments onto adjoining properties or into existing drainage facilities. The City Engineer may request stoppage of work during construction if proper controls for soil erosion, siltation, and sedimentation are not being provided by the developer or contractor. The City Engineer may take the necessary steps to provide corrective measures, and the cost of such services will be charged to the developer. This does not relieve the developer or contractor of downstream liabilities. No project will be released from bond from failure to comply with this regulation and without cleanup and repair of damages. Final inspection requires all drainage facilities free from depositions of erosion, siltation, and construction debris.
      (v)   Final Cleaning Up. Upon completion of the work and before acceptance, the subdivider and/or contractor shall clean all ground occupied or affected in connection with the work. The entire area shall be left in a neat and presentable condition.
