<br />CITY OF SUNNY ISLES BEACH SECTION 02762 - 10 <br />TELEVISING STORM SEWER SYSTEMS <br /> <br /> <br />shall be withdrawn, and Contractor shall televise the line from the opposite <br />direction. <br /> <br />N. The camera shall be directed through the sewer in a downstream direction, with <br />the flow, at a uniform, slow rate. In no case will the video camera record while <br />moving at a speed greater than 30-feet per minute. If, during the course of the <br />Project, the inspection is rejected due to camera speeds exceeding 30-feet per <br />minute, the inspection recordings shall be redone, at no additional cost to the <br />Owner. <br /> <br />O. If a new manhole is discovered in the field that was not on current maps, a new <br />manhole identification number will be assigned by Owner. The Owner shall <br />assign the manhole the next number above the highest manhole number within <br />the sub area. The data / video files shall then be re-named to include the new <br />MH ID, and a new CCTV inspection shall be started from the new MH ID. <br />Contractor shall consult with the Owner for assignment of new manhole <br />identification numbers. Contractor shall note in the inspection form comments <br />that a new manhole ID has been assigned as well as provide a marked-up map <br />indicating the newly found manhole and assigned manhole ID. <br /> <br />P. Flow levels within existing sewers to be inspected shall not exceed 5% of the <br />pipe diameter. If water levels prevent adequate televising of the sewer, then <br />conducting the Work during low flow periods or other methods like plugging and <br />bypass pumping shall be implemented. <br /> <br />Q. The survey unit shall be slowed, stopped, or backed up to perform detailed <br />inspections of significant features. The camera shall be stopped at all defects, <br />changes in material, water level, size, side connections, manholes, junctions, or <br />other unusual areas. When stopped at the defect or feature, the operator shall <br />pan the camera to the area and along the circumference of the pipe. <br /> <br />R. On all storm sewers which have sags or dips, to an extent that the television <br />camera lens becomes submerged during the television inspection, the Contractor <br />shall use a high-pressure cleaner to draw the water out of the pipe, bypass <br />piping and pumping, or othermeans, to allow the full circumferential view of the <br />pipe and identification of pipe defects, cracks, holes, and location of service <br />connections. <br /> <br />S. The camera unit shall be paused long enough at areas suspected of leaking to <br />determine if a leak exists currently or if deposits have occurred.
