2.1 GENERAL The contractor shall include the recommended tube thickness for each manhole to
       manhole section within the scope of work, and shall supply design calculations indicating
       how the tube thickness dimensions were obtained. Each tube shall be designed to withstand
       internal and/or external loads as dictated by site conditions. Design calculations shall be in
       strict accordance with ASTM F-1216-93-X.1. Assume pipe ovality 3% and water loading
       50% of average depth.

2.2 CAPACITY: The reconstructed pipe shall be designed such that the resulting capacity of the
       pipe is equal to or greater than that of the existing pipe. In order to maximize the capacity of
       the reconstructed pipe the inside diameter must be as large as possible, therefore increasing
       the effluent carrying area of the pipe.

2.3 SIZING: The tube shall be designed to a size that, when cured, will fit tightly against the internal
       circumference of the original conduit; this tight fit minimizes loss of original pipe size.
       Allowance for longitudinal and circumferential stretching of the tube during installation
       shall be made by the contractor.

       The contractor shall design the length of the tube to effectively carry out installation and
       sealing at end points. The contractor shall verify pipe dimensions shown on contract
       drawings before designing and reconstructing pipe.
2.4 INSTALLATION: The tubes shall be designed to withstand negotiation of offsets, gaps, angles
       (not more than 90º), and grades without damage to the tube during the installation process.
       Individual runs can be made over one or more manhole-to-manhole sections, as determined
       in the field by the contractor. The tubes shall be inverted in accordance with ASTM F-1216-
       93.

       loose debris, 1 to 2 inches in depth, exists within the pipeline.

       Medium Cleaning – where it has been determined through a visual inspection that medium deposits
       of loose debris, 2 to 4 inches in depth, exists within the pipeline.

       Heavy Cleaning – where it has been determined through a visual inspection that heavy deposits of
       loose debris or root growth exists within the pipeline. Heavy equipment will be used to facilitate the
       removal of heavy deposits.

       Bypassing Sewage: The contractor shall bypass the sewage around the sections of sewer that to be
       lined. The bypass shall be made by plugging an existing upstream manhole, if necessary, and
       pumping the sewage into a downstream manhole of capacity and size to handle the flow. At the end
       of each working day, temporary tie-in shall be made between the relined section and the existing
       system and the bypass plug removed, but only after relined section has been cured for the proper
       time limit.

       Line Obstructions: It shall be the responsibility of the contractor to clear the liner of obstructions and
       solids that will prevent the insertion of the liner.

       Pipe Repair: Any pipe repair required to reline the pipe shall be made by the contractor prior to
       relining.

4.3 SERVICE CONNECTIONS: Opening of Service Connections: After the liner has been cured, all
       existing active services shall be reconnected, as directed by the owner and/or Engineer.

       The recommendation of services shall be done, unless otherwise directed by the owner and
       Engineer without excavation, from the interior of the pipeline by means of a television
       camera directed cutting device. Location of the service shall be from the procured in place
       pipe inspection records and camera observation.

                                SECTION 02573
                       TELEVISION INSPECTION OF SEWERS


PART 1 - GENERAL

1.1   DESCRIPTION
      A.   Work Included: Furnish all necessary labor, materials, supervision and equipment to
           satisfactorily inspect gravity sewer lines and sewer service pipes as required by the
           Contract Documents by means of a closed circuit television system.
      B.   Related Work Specified Elsewhere: Sewer line cleaning and sewer flow control are
           specified in the appropriate sections in the Division.

PART 2 – PRODUCTS

2.1   MATERIALS AND EQUIPMENT
      A.   The cameras shall be designed and constructed for sewer line inspection work. The
           mechanical design of the lens shall allow it to turn and rotate 360 degrees to provide
           a close up view of sewer pipe walls and sewer service pipes. The camera shall be
           designed to maintain proper orientation of the picture while the lens is turning and
           rotating.
      B.   The cameras shall be operative in 100% humidity conditions.
      C.   The lighting for the cameras shall be suitable to allow a clear picture of service pipes
           and the entire periphery of the mainline sewer pipe, such that joints, root intrusions,
           cracks, offset joints, deposits, etc. can be seen and identified by the Engineer.
      D.   The lens focus and rotational capabilities and the light intensity will be remotely
           controlled from an above ground television “studio”.
      E.   The cameras shall produce a continuous, full color picture with a quality acceptable
           to the Engineer.

PART 3 – EXECUTION

3.1   PERFORMANCE
      A.   Flow Control:
           1. The minimum of 75% of the periphery of the sewer line shall be visible at all
           times.
           2. The Engineer may require that the line be plugged so that the entire periphery can
           be inspected.
      B.   Operation:
           1. Perform inspection of sewer lines after lines have been suitably cleaned.
           2. When inspecting newly constructed sewer lines, introduce water into the sewer
           lines to be tested from the upstream manhole prior to the television inspection, but no
           more than 24 hours in advance of the inspection.
           3. Lines will be suitably isolated from the remainder of the sewer line as required.
           4. Move the cameras through the line in either direction at a uniform rate as directed
           by the Engineer.
           5. The Engineer may require Contractor to pull cameras back to get a second view of
           a section of pipe.
           6. Use manual winches, power winches, television cable reel powered rewinds, high
           pressure hose and reels on jet-cleaning trucks, or a flexible pole, to move the camera
           through the sewer.
     7. The screen monitor and winch operators shall be in full communication at all
     times.
     8. Remove all wires, screens, sand bags, etc. used in the television inspection process
     from the sewers at the completion of inspection of each sewer section.
C.   Measurement:
     1. Measurement for location of defects, service connections, etc. shall be accurate to
     two-tenths (0.2) of a foot over the length of the section being inspected.
D.   Records:
     1. Printed records shall be provided, reflecting location of defects, service
     connections, etc. shall be recorded and stored to “Wincan” digital reporting software
     or equivalent.:
     a.      Keep records and supply to the Engineer when the work has been completed.
     b.      Show the exact location in relation to adjacent manholes, of each infiltration
             point discovered by the television camera.
     c.      Show locations of laterals, unusual conditions, roots, break-in storm sewer
             connections, collapsed sections, presence of scale and corrosion, and other
             discernible features.

     2. Inventory the houses and apparent empty lots bordering each section of sewer line
     that is inspected and compare results to the number and location of house services
     found during the inspection. Log inconsistencies and report them to the Engineer.
     3. Video/Photographs:
     a.       A copy of the video shall be provided to the Engineer in DVD format.
     b.       The video shall be digitally recorded, indexed by pipe section (labeled by
              manhole number or other means acceptable to Engineer) and allow for
              printing of still photographs.
     c.       Photographs shall be printed at Engineer’s request and shall be identified on
              the back as follows:

            Date:
            Section, MH#:                         to MH#:
            Diameter of Sewer:
            Distance from MH#:                    is
