C. Pipeline Cleaning shall be classified as follows:

1) Standard Cleaning: Cleaning to remove dirt, rock, sand and other deleterious materials from the pipeline and manhole/ structures.

2) Root Removal: Removal of roots to within ¼” of the inside pipeline wall, using standard robotic or mechanical equipment specific for the purpose

3) Lateral Protrusion Removal: Removal of protruding pipe to within ¼” of the inside pipeline wall, using standard mechanical equipment specific for the purpose.

4) Tuberculation Removal: Tubercles (scales and corrosion build-up) shall be removed with standard mechanical equipment to restore pipeline to at least 90% of its original inside diameter.

5) Defective Liner Removal: Liner shall be removed using standard mechanical equipment specific for the purpose.

6) Heavy Cleaning: This cleaning will be considered necessary for roots, grease, and other settled deposits which are greater than 25% by height and/or cross-sectional area within the pipeline. Heavy Cleaning is defined as requiring 50% more time to clean than under normal conditions. This must be supported by visual proof or approval by County inspector. Grease shall be removed using standard mechanical equipment specific for the purpose.

7) Concrete Removal at Manhole: Concrete shall be removed using standard mechanical equipment specific for the purpose.

B. The cleaning device shall have sufficient power to force and move the debris for extraction.

C. Where required, equipment shall remove roots and lateral protrusions to within ¼” of the inside pipeline wall without damage to the pipeline.

D. Where required, equipment shall remove scale and rust build-up (tuberculation) to restore at least 90% of the pipeline inside diameter without damage to the pipeline.

E. The cleaning method employed shall maintain normal pipeline flows during the cleaning process.

F. Solids shall be removed by vacuuming the debris to the surface. Approved equipment shall decant and separate the water from the solids before it is transported to an approved disposal site. Liquid decanted from the solids shall be returned to the pipeline system.

1.7 REMOVAL OF DEBRIS

A. Materials generated by the cleaning operation shall be removed by vacuuming at the upstream or downstream manhole of the segment being cleaned. Suitable traps, screens and weirs shall be used to prevent the movement of solids to adjacent segments of pipeline.

B. Waste materials and debris resulting from the pipeline cleaning operations, shall be removed, drained of excess fluid, and conveyed by the Contractor to an approved waste disposal site. The disposal site shall be accessible during Contractor working hours. All permits required for loading and transporting the waste material shall be the responsibility of the Contractor. Under no circumstances shall the debris removed for the pipelines be discharged onto the streets or into ditches, catch basins, or stormwater system.

C. Unless otherwise provided for in the price schedule of the pricing table, all costs associated with the removal, draining, loading, transporting, and disposal of debris and waste materials generated by the cleaning operation shall be considered incidental to the cleaning of the pipelines, and; therefore, considered included in the Unit Prices bid for cleaning.

1.8 TELEVISION INSPECTION

Equipment and TV Picture Quality: The TV camera must be specifically designed for pipe inspection, small, rugged and waterproof. The camera must have its own light source suitable to provide a clear bright, color picture of the entire periphery of the pipeline.

The camera shall have the ability to turn and view into each service/lateral and focus on any pipeline damage and defect. Contractor should also have self-propelled crawlers with lateral launch cameras, push cameras, and crawlers capable of inspecting pipeline diameter 6” and greater. The camera, television monitor, and other components of the video system shall be capable of producing picture quality adequate for the purposes of the inspection. The County shall determine the adequacy of the picture quality when the work is started.

A. TV Inspection Procedures:

1) The camera system shall be capable of assessing (making visible) 75% of the pipeline at any time during the inspection. Excessive water in the line shall be removed by the Contractor for proper inspection of the pipeline.

2) The camera system shall be capable of moving through the pipeline in either direction at a moderate rate, stopping when it is necessary to permit proper documentation of the pipeline’s condition on the Digital Video Record, in the database, and for the CCTV Assessment Report. The camera shall not travel at a speed greater than thirty (30) feet per minute.

3) If, during the inspection operation, the television camera will not safely pass through the entire pipeline segment, the Contractor shall set up the equipment so that the inspection can be performed from the opposite manhole or other end of the pipeline segment. If, again, the camera fails to pass through the pipeline segment, the Contractor shall notify the County for further directions.

4) In the event that the TV camera encounters broken pipeline and there is a possibility that continuation of the inspection could cause the TV camera to become lodged in the pipeline or result in additional pipeline damage or collapse, the County may elect to discontinue the inspection of that pipeline segment, and to affect repairs to the damaged pipeline.

B. Measurements: The video equipment used shall provide accurate distance measurements, in feet, for locating laterals, infiltration points, roots, pipeline damage and defects, and other unusual conditions, relative to the reference pipeline end segment (0.00’). The accuracy of the measuring device shall be verified by taking a reading at the entrance of the away manhole or pipeline end and comparing it with a surface measurement made between manholes or end points, with a steel tape or walking meter (Roll-A-Tape). The accuracy of the recorded distance measurements must be satisfactory to the County.

C. Documentation: Documentation of the television inspection shall be prepared by the Contractor at the site on a daily basis. The County shall observe that documentation (entering voice data on the audio-video USB Drive and preparing computer generated inspection logs) is being properly, accurately and legibly done during the TV inspection of each pipeline segment.

1) The Contractor shall place informational door hangers provided by the County, on customer’s doors forty-eight (48) hours prior to commencement of work in a particular area. The Contractor shall make every effort possible to notify each customer whose service may be affected by the cleaning and televising operations.

Use of root saws are permitted, as necessary. Contractor shall pan, tilt, and zoom all connections and at both the upstream and downstream manholes to provide video evidence of condition. All service/lateral locations and obstructions, such as dropped joints and protruding services, pipeline damage, and infiltration points shall be noted on the Digital Video Record and recorded in the CCTV Assessment Reports.

B. The Contractor shall notify the County if any severe problems are discovered during televising. If conditions such as a broken pipeline or major blockages are found that will prevent proper cleaning, or where additional damage would occur if cleaning is attempted or continued, the Contractor shall notify the County and request further direction on how to proceed. All cross bores are to be indicated on the survey using NASSCO PACP Condition Code ‘OBI’.

C. Any damage caused by the Contractor to any existing pipeline or structure will be immediately repaired to a condition equal to or better than its original condition at the Contractor’s expense.

3.3 PROTRUDING SERVICE/LATERAL CONNECTIONS AND ROOTS: When directed by the County, existing service/lateral connections and roots that protrude into the main pipeline shall be removed to within one-quarter (1/2”) inch of the inside wall of the main line pipeline by means of robotic and/or mechanical equipment if the crawler is unable to pass by the lateral connection. When necessary, service/lateral connection and root protrusions shall be ground using grinding tools specifically designed for this purpose. The finished product shall be uniform and smooth.

3.4 TRAFFIC CONTROL AND MAINTENANCE OF TRAFFIC: Pipelines to be cleaned and televised may be in backyard easements; or in light traffic subdivision roadways, collector roads, or highways requiring Maintenance of Traffic plans conforming to Florida Department of Transportation and Sarasota County requirements

3.5 CLEANUP: Cleanup is an essential part of the work.
