<br />Version 2/14/2020 Page - 14 Public Works Quote <br />d. Should the Contractor’s internal inspection equipment become immobilized within a storm <br />drain, said equipment shall be removed from the line. If excavation is required to retrieve the <br />Contractor’s equipment, the excavation shall be accomplished by the Contractor at his <br />expense. Following removal of the equipment, the Contractor shall restore the storm drain <br />and the site to conditions consistent with new pipe work in accordance with City <br />specifications at no additional cost to the Owner. <br />e. The Contractor shall provide the City with an exported file with the television data on an <br />external hard drive with a USB 2.0 connection, at the preference of the Owner. All hard drives <br />submitted shall become property of the City. Each video shall be named according to the <br />“Pipeline ID” format. The video shall document in a clear and continuous manner the <br />condition of the sewer segment from the upstream manhole to the downstream manhole. No <br />interruptions or missing segments shall be allowed unless noted in writing by the Engineer. <br />The City will reject any video that has foggy or static conditions on it. <br />f. The date of the television inspection and the distance that the camera has traveled through a <br />particular storm drain reach shall be continuously displayed on the recording. All recordings <br />obtained during the work shall be turned over to the Engineer and shall become the property <br />of the Owner. All costs for recordings shall be included in the Unit Prices for the Work. If the <br />recording is not complete or the quality is not satisfactory, the storm drain shall be <br />reinspected at the Contractor’s expense. <br />g. The television video supplied by the Contractor shall be compatible with existing replay <br />equipment owned by the City. <br />h. Recordings and inspection reports shall be submitted to the City Engineer within seven (7) <br />days of inspection. <br />8. Coordination with Televising Operations <br />a. The Contractor is allowed to operate televising equipment simultaneously with the cleaning <br />equipment to check on the progress of the current cleaning operation in a sewer segment. <br />However, in these situations, the use of televising equipment shall be incidental to the sewer <br />cleaning operation and will not be measured or paid for. <br />9. Acceptance of Cleaning Operation <br />a. Acceptance of storm sewer line cleaning shall be made upon the successful completion of <br />the television inspection and shall be to the satisfaction of the Engineer. If television <br />inspection shows the cleaning to be unsatisfactory, the Contractor shall be required to <br />reclean and reinspect the storm sewer line until the cleaning is shown to be satisfactory. If <br />there are areas where television inspection is not able to be performed, the Engineer may <br />require the Contractor to pull a double squeegee (with each squeegee the same diameter as <br />the storm sewer) through each manhole section as evidence of adequate cleaning. <br />b. In addition, on all storm sewer lines which have sags or dips, to an extent that the television <br />camera lens becomes submerged for three (3) or more lineal feet during the television <br />inspection, the Contractor shall pull double squeegee and/or sponges through the line in <br />order to remove the water from the dips or sags. Water removal through squeegees and/or <br />sponges shall be performed until the television camera lens will no longer be submerged. <br />This requirement may be waived by the Engineer if the water in which the camera lens is <br />submerged, is clear enough to allow the identification of pipe defects, cracks, holes and <br />location of service taps. <br />c. The basis for non-acceptance by the Engineer shall be any evidence of poor cleaning <br />observed on the video tape recording that prevents the proper internal inspection of the drain <br />reach. No additional payment shall be made for the re-cleaning of drain reaches to an <br />acceptable condition regardless of the number of times re-cleaning may be required. All <br />measurements for payment shall be based upon the linear feet of pipe cleaning and <br />television inspection. <br />10. Damaged Pipe Sections <br />a. The Owner anticipates the possibility that some sewers will have broken or collapsed <br />sections that prevent cleaning and televising equipment access. When these sections are <br />encountered, the Owner will make a decision whether to delete the entire section from the <br />Contract or obtain quotes for a dig repair with the current or other Contractor. <br />b. If the decision involves a dig repair, the sewer cleaning crew may clean and televise another <br />sewer segment indicated on the plans. Once the dig repair has been completed, the sewer <br />cleaning Contractor will return to the repaired sewer section and complete the cleaning and <br />televising operations.
