During this process we check the wash logs ensuring they match the sewer <br />lines inspected that particular day. Once all data is verified to be correct the QC process <br />begins. <br />Our QC tech views each video in its entirety first checking for proper lighting and centering <br />of the camera. The video must have a clear picture, free of any kind of distortion or <br />interferences and the audio must be clear and concise. Every line must also begin with a <br />view of the open manhole proceeding uninterrupted in the downstream direction with the <br />insertion of the camera into the manhole. <br />All sewer lines are inspected using NASSCO's standard coding system. During the QC <br />process all lines are checked for the proper logging of each defect. All defects must be <br />accurately coded using the proper NASSCO code, o -clock position(s) and footage. The <br />inspection shall include location of all laterals, cracks, roots, deposits, infiltration, ex- filtration <br />and other conditions pertaining to the sewer line. if during the QC process the line is deemed <br />to be unsatisfactory, the line is rejected and re- inspected. After the lines have passed the <br />QC process they are saved on multiple hard drives ensuring nothing is lost if the working <br />hard drive should fail. <br />Once this step is complete all line segments are logged on an Excel Spreadsheet. This <br />spreadsheet shows progress of our current task and includes important information we feel <br />the City should be aware of; including RVP information, Red Flags, etc. Any lines having <br />nm_. _ . <br />City of Santa Ana Bid #13020 <br />Closed Circuit Teievhuon (CCTV) Inspection of Sanitary sewers <br />21831 Barton Road <br />Grand Terrace, CA 92313 <br />tea`' 909422.8990 P 9094224841 F <br />CA #884167 <br />
