I <br /> 15) Circular loops are standard installations. Where shown in the Plans, the <br /> contractor shall install quadrupole loops at stop lines due to stub-out <br /> diameter. At locations where quadrupole loops are shown and adequate <br /> stub-out diameter exists, round loops may be substituted for quadrupole <br /> loops. <br /> ' Existing Traffic Loops <br /> The Contractor shall notify the Area Traffic Engineer through the Engineer a <br /> minimum of five working days in advance of pavement removal or grinding in <br /> 1 areas with existing loops. <br /> If the Engineer suspects that damage to any loop, not identified in the Plans as <br /> being replaced, may have resulted from Contractor's operations or is not <br /> operating adequately, the Engineer may order the Contractor to perform the field <br /> tests specified in Section 8 20.3(14)D. The test results shall be recorded and <br /> submitted to the Engineer. Loops that fail any of these tests shall be replaced. <br /> Loops that fail the tests, as described above, and are replaced shall be installed in <br /> ' accordance with current City of Everett design standards and Standard Drawings, <br /> as determined by the Engineer. <br /> If traffic signal loops that fail the tests, as described above, are not replaced and <br /> operational within 5 working days, the Contractor shall install and maintain interim <br /> video detection until the replacement loops are operational. The type of interim <br /> video detection furnished shall be approved by the Engineer prior to installation. <br /> 8-20.4 Measurement <br /> 1 Section 8-20.4 is supplemented with the following: <br /> "Vehicle Loop Detectors", for both loop perimeter and home run, shall be <br /> measured by the linear foot of the neat sawcut line in place in the roadway. No <br /> additional measurement will be made for the installation of lead-in conduit and <br /> shall be included in the measurement <br /> ' "Loop Detector Lead-in Cable" shall be measured by the linear foot of the neat <br /> line of conduit between the controller cabinet and loop splice. No additional <br /> measurement will be made for coiled loop detector cable in junction boxes or <br /> cabinets. <br /> "Conduit Pipe 2 In. Diam." shall be measured by the linear foot of the neat line of <br /> conduit between the junction box and the curb line. No additional measurement <br /> will be made for sweeps or elbows in junction boxes or at the curb line. <br /> 8-20.5 Payment <br /> Section 8-20.5 is supplemented with the following: <br /> "Vehicle Loop Detectors," per linear foot. <br /> HOT MIX ASPHALT OVERLAY 2017 PAGE 5 OF 10 MARCH 2017 <br /> WORK ORDER# PW 3642 <br /> DIVISION 8 <br />
