Specifications include, but are not limited to: 2.1 - Project Coordination The chosen vendor will attend a Project Kick-Off meeting to review the details of this project with appropriate Public Service Staff and City contractor Upper Arlington will provide all CCTV data for City-owned gravity sanitary sewer totaling approximately 70,000 LF of footage in usable video format. The CCTV footage will be in usable video format and quality equal to that in which a person would be required to complete a condition assessment of the pipe. The inspection video provided will provide a clear unobstructed view of the pipe with nothing on the inspection camera lens such as water grease, soap suds, etc. The video file naming will be “sewer district _ upstream manhole _ downstream manhole (ex:22-01-02).” The inspection data will have header data displayed for approximately (5) five seconds at the beginning of each inspection. This information will include the diameter of the pipe, pipe material, upstream manhole, downstream manhole, pipe segment reference, the direction of the survey, location information, date and time of inspection, manhole depth, etc. For the most part camera setup will match the pipe diameter. An 8” camera setup will be used for an 8” pipe, and a 10” setup for a 10” pipe. Because of CIPP lining defects and Deposits Attached (DAE), there may be instances where a smaller diameter setup will need to be used. Ex: 6” set up in an 8” pipe or 8” set up in a 10” pipe. 2.2 - CCTV Review All of the City-owned gravity Sanitary Sewers or approximately 70,000 LF of sewer video will be evaluated with AI Sewer Observation Coding. Defects such as cracks, fractures, breaks, holes, roots, and deposits need to be coded using the AI software. Defects will have a footage and percentage reduction in cross-sectional area for deposits, sags, and other defects that require that scoring information. Clock position will not be included in these inspections. Defects such as sags, deformations, collapses, inflow and infiltration (I/I), intruding pipes, changes in pipe material, and settled deposits must be confirmed by the vendor and documented with the output file. Using the City’s existing GIS database, the software results will be visually displayed showing the condition of each pipe segment, the location of each observation along the respective pipe segment, and an image with each observation. Please include any service fee to cover the cost of maintaining cloud-based infrastructure and cloud-based processing.
