820.01 DESCRIPTION.
Test all electrical items referred to in Category 800.
820.02 MATERIALS.
All materials and equipment installed as part of the permanent installation shall be new, ULUnderwriters Laboratories, Incorporated listed or labeled, and meet NECNational Electric CodeNortheast Corridor, NESCNational Electric Safety Code, NEMANational Electrical Manufacturers' Association, IESIlluminating Engineers Society, and local codes applicable to the area of installation.
820.03 CONSTRUCTION.
820.03.01 General. All installations shall meet NECNational Electric CodeNortheast Corridor, NESCNational Electric Safety Code, local utility company requirements, and State and local laws and ordinances governing the work. All electrical work shall be under the direct supervision of a master electrician licensed in the State of Maryland or in the county where the work is performed. All work done under Sections 804, 805, 806, 807, 810 (except loop wire), 811, 814, 816, 817, and 820 shall be performed by a journeyman electrician. Obtain and pay for all permits, licenses, and inspection fees.
820.03.02 Testing. Supply all personnel and equipment required to perform the following tests. Furnish four certified copies of the complete test reports to the EngineerAny person designated by the Administrator or the procurement officer, acting directly or through his duly authorized representative, such representative acting within the scope of the particular duties assigned to him or of the authority given him..
At least 30 days prior to the commencement of each test, submit the types, styles, or catalog numbers of all required testing equipment. Include a written certification stating when the testing equipment was last calibrated by an AdministrationShall mean any one of the Administrations within the Maryland Department of Transportation, as listed in GP 1.02. approved testing agency. The calibration date shall be within 180 days of the date when the tests are to be performed. Perform all tests in the presence of the EngineerAny person designated by the Administrator or the procurement officer, acting directly or through his duly authorized representative, such representative acting within the scope of the particular duties assigned to him or of the authority given him..
Immediately repair or replace any defects found in the completed installation.
(a) Ground Resistance Testing. Use a megger ground tester, using the null balance fall of potential method. Corrected readings greater than 25 ohms will not be accepted.
(b) Circuit Testing. Determine the insulation resistance on all cables of every circuit except those installed in lighting structures. Cable insulation resistance shall be at least 10 megohms at 500 volts D.C., except loop detector wire and loop detector lead in shall be at least 100 megohms at 500 volts D.C.
Demonstrate to the EngineerAny person designated by the Administrator or the procurement officer, acting directly or through his duly authorized representative, such representative acting within the scope of the particular duties assigned to him or of the authority given him. that all conductors are continuous, free from short circuits and unspecified grounds, and that all circuits are properly connected.
(c) Performance Testing. Conduct a performance test using the design power source. Operate the electrical system, including automatic control equipment, for 30 consecutive days. If any component fails, replace it immediately and continue the test. Record each fault, the method and date of correction of each, and the beginning and end of the 30-day test period. If more than 5 percent of any component fails during the test, replace the component and restart the 30-day test cycle for the entire system.
(d) Illumination Testing. Conduct an illumination test, conforming to procedures approved by the AdministrationShall mean any one of the Administrations within the Maryland Department of Transportation, as listed in GP 1.02., to determine the illumination characteristics of the roadway lighting installation.
820.03.03 Traffic Signal Testing. Conduct testing without causing a hazard to the traveling public.
Maintain all new materials until satisfactorily tested and their operation is accepted by the EngineerAny person designated by the Administrator or the procurement officer, acting directly or through his duly authorized representative, such representative acting within the scope of the particular duties assigned to him or of the authority given him..
Signal heads and signs that are in place, but not in use, shall be entirely covered with opaque burlap.
After completion, testing, and acceptance, place new traffic signals on flashing operation for a 72 hour period prior to placing the signals on full color operation. Existing full color and flashing signals shall not flash, but shall be kept in operation until the new signal is completed, satisfactorily tested, and approved.
Remove STOP signs at new full color signals at the end of the 72 hour flashing period. Provide a log of the date and time of removal to the EngineerAny person designated by the Administrator or the procurement officer, acting directly or through his duly authorized representative, such representative acting within the scope of the particular duties assigned to him or of the authority given him..
Upon acceptance and placement of the new traffic control device into operation, remove unnecessary signal heads, signs, spans, and mast arms.
New traffic signals, exclusive of signal system interconnect installation, may be placed into operation when testing is completed and upon acceptance by the EngineerAny person designated by the Administrator or the procurement officer, acting directly or through his duly authorized representative, such representative acting within the scope of the particular duties assigned to him or of the authority given him.. Upon completion of the signal system interconnect installation, the signal system interconnect shall also be satisfactorily tested and approved by the EngineerAny person designated by the Administrator or the procurement officer, acting directly or through his duly authorized representative, such representative acting within the scope of the particular duties assigned to him or of the authority given him..
820.04 MEASUREMENT AND PAYMENT.
General electrical work and testing and the as-built drawings will not be measured but the cost will be incidental to the other pertinent items specified in the Contract DocumentsThe written agreement executed between an Administration and the successful bidder, covering the performance of the work and furnishing of labor, equipment and materials, by which the Contractor is bound to perform the work and furnish the labor, equipment and materials, and by which the Administration is obligated to compensate him therefore at the mutually established and accepted rate or price. The Contract Documents shall include the Invitation for Bids, Notice to Contractors, Instructions to Bidders, Proposal, Contract Forms and Bonds, General Provisions, Specifications, Supplemental Specifications, all Special Provisions, all Technical Provisions, all Plans and Notices to Proceed, also any written Change Orders and Supplemental Agreements that are required to complete the construction of the work in an acceptable manner, including authorized extension thereof.
