blocks, the spade terminals shall be soldered as well as crimped to the OF wire. All detector lead -in cable shall be continuous - no splicing is permitted. M. After the loop conductors are installed in the pavement, the slots shall be filled to within 1/8" of the pavement surface with the appropriate sealant. All excess shall be removed. N. Detector loop lead -ins shall be installed in conduit from the gutter to the splice box. After installation of loop wires, gutter end of conduit is to be sealed with duct seal and excavation is to be filled with sand to within 1 -1/2" of road surface and capped with asphalt. O. All splices shall be soldered to ensure constant low resistance and must be insulated in such a manner that the installation maintains resistance to ground of not less than 100 megaohms. To ensure that the loop installation is correct, a continuity check of the loop writing and a resistance check of this loop -to- ground shall be performed using a "megger" or other suitable insulation tester, with a representative of the City Engineer present. Loop readings that decrease below 20 megaohms during the guarantee period shall be considered below minimum limits and shall require replacement. P. The contractor shall test the detectors with a motor- driven cycle, as defined in the California Vehicle Code, that is licensed for street use by the Department of Motor Vehicles of the State of California. The unladen weight of the vehicle shall not exceed 200 pounds and the engine displacement shall not exceed 100 cubic centimeters. Special features, components or vehicles designed to activate the detector will not be permitted. The contractor shall provide an operator who shall drive the motor - driven cycle through the response or detection area of the detector at not less than three (3) miles per hour nor more than seven (7) miles per hour. The detector shall provide an indication in response to this test. Q. Chevron asphalt loop sealant or equal shall be used. R. Adjacent loops shall be tied to the same four - channel detector. S. The number of lead -in -cable required to achieve the specified detection shall be installed. T. Where Type "A" loops are indicated on the plans, except for speed monitoring installation, a six -foot diameter circular loop may be installed in lieu of the shape shown on the plans. The sides of the slot shall be vertical and the minimum radius of the slot entering and leaving the circular part of the loop shall be 1- 1/2 inches. U. If any part of the loop conductor, including the portion leading to the adjacent pull box, is damaged by the contractor's operations, the entire detector loop shall be replaced. If any adjacent loop is damaged during such replacement, that loop shall also be replaced. 3.16 RESTORATION OF EXISTING IMPROVEMENTS A. Existing pavement or other improvements removed or damaged due to the installation of work items shall be replaced in kind to the satisfaction of the City Engineer, at the Contractor's expense. B. Existing landscaping, irrigations, or plantings removed, damaged or disturbed due to the work items shall be replaced in kind to the satisfaction of the City Engineer, at the Contractor's expense. C. All construction areas shall be left in a clean, neat and workmanlike condition. All construction waste, rubbish and debris remaining upon completion of the work shall become the property of the contractor unless otherwise specified herein or noted on the plans and shall be removed from the worksite by contractor and disposed of off -site in a lawful manner to the satisfaction of the City Engineer. 3.17 ACCEPTANCE TEST AND TURN ON A. The work item will not be considered acceptable until it has been energized and visually inspected by the City Engineer. Prior to acceptance testing, all equipment as shown on the Plans shall be installed and operable, including but not limited to, pedestrian signals, pedestrian push buttons, vehicle detectors, lighting, signs, and pavement delineation. B. All louvers, visors, and signal faces shall be directed to provide maximum visibility. C. Contractor shall pay all energy costs until the street light system has successfully passed the acceptance test and initial turn on. D. Initial turn on of signal systems shall be made between 9 a.m. and 2 p.m., unless specified otherwise. SIGNALS LIGHTING AND ELECTRICAL SYSTEMS 16500 -14 EMERGENCY VEHCILE PREEMPTION PROJECT 2010
