683.01 Description. In additional to the requirements set forth in Section 681, lighting
assemblies shall consist of high mast lighting assemblies, low mast lighting assemblies, underpass lighting assemblies and portable po wer units. High mast lighting assemblies shall consist of a pole, lowering device, luminaires, anchor bolts, lamps, and miscellaneous hardware. Low mast lighting assemblies shall consist of pole, arm, luminaire, anchor bolts, breakaway device, lamp, and miscellaneous hardware. Underpass lighting assemblies shall consist of the luminaire, conduit box, lamp, fuses and miscellaneous hardware. The portable power unit shall consist of a heavy-duty industrial type reversible power unit, dry type transformer and hand held control unit. Where called for on the plans, lighting fixtures can be of several different types.

683.03 Construction Requirements.
683.03.1 High Mast Lighting Assemblies.
683.03.1 1--Field Assembly of All Components. The pole section shall be fitted together
and supported by blocks. The Contractor shall use the piece marks provided by the manufacturer. The proper joint overlap shall be provided and verified. The sections shall be lashed together by an approved method that will not damage galvanizing during erection. The wiring, lowering device, cables, and all components, except luminaires, shall be installed on the pole before erection, as per manufacturer's guidelines. No field welding is permitted on the pole shaft. Any damaged areas on the pole surface shall be coated with a zinc rich paint before erection.
683.03.1 2--Setting and Aligning Poles. The pole shall be lifted at a point as far above
center of gravity as possible. The lifting shall be smooth, continuous and free of abrupt motions. The base shall be placed on pre-le veled nuts and suppor ted by the crane until anchor bolt nuts are tightened. Cables or chains that may damage galvanizing shall not be tied to poles. Poles shall be plumbed by the method shown on the plans. The plumbing shall be done early in the morning while minimum heat is affecting the pole and while there is no appreciable wind. After the pole is plumb, the anchor bolt nuts shall be tightened and secured against loosening by tightening the nuts until there is an abrading or coining of the base plate under the nut. The space between the top of the foundation and the bottom of the base plate shall be grouted a maximum of three (3) inches deep, making two (2) drainage openings with ¾- inch PVC pipe for internal condensate drainage.
683.03.1 3--Cable Installation. Care shall be taken to remove all twisting from hoisting
cables before installation and/or operation of the lowering device.
683.03.2 Low Mast Lighting Assemblies.
683.03.2 1--General. All component parts of the low mast lighting assemblies shall be
installed as per manufacturer's guidelines and this specification.
683.03.2 2--Setting and Aligning Poles. All wiring, luminaires, and other components
shall be installed as per plans before pole erection. Poles shall be lifted into place on the foundation using pre-leveled nuts for alignment. All poles shall be as nearly plumb as possible.
683.03.2 3--Alignment of Luminaires. Luminaires shall be installed and aligned to
provide the proper lighting pattern on the roadway. Pavement overhang shall be one (1) foot for bracket arm type assemblies or as shown on the plans. Post top mounted assemblies shall be properly aimed.
683.03.3 Underpass Lighting Assemblies. All component parts of the underpass
luminaire shall be installed as per manufacturer's guidelines and the plans.
683.03.4 Portable Power Unit. The power unit shall be constructed in accordance with
Underwriters Laboratories Standards and shall be so listed.
683.04 Method of Measurement. High mast and low mast lighting assembly, of the type
specified, will be measured as a unit quantity per each, which measurement shall include the pole, lowering device, luminaires, lamps, pole wiring, conduit, anchor bolts, ground rods and all other items necessary to complete installation. Underpass lighting assembly, of the type specified, will be measured as a unit quantity per each, which shall include lumi naire, lamp, wiring, conduit box, fuse, and mounting hardware. The portable power unit, complete in place, will be measured as a unit quantity per each, which shall include all items necessary to complete the unit.
683.05 Basis of Payment. High mast and low mast lighting assembly, measured as
prescribed above, will be paid for at the cont ract unit price per each, which price shall be full compensation for furnishing all materials, placing, erecting, installing, connecting, testing, poles, lowering device, luminaires, lamps, breakaways, ground rods, conduits, cable, wiring, all hardware, final cleaning up, equipment, labor, tools, and incidentals necessary for completion of the work. Underpass lighting assembly, measured as prescribed above, will be paid for at the contract unit price per each, which price shall be full compensation for furnishing all materials, for all construction, installing, connecting, te sting, luminaires, lamps, conduit boxes, hardware, wiring, connectors, miscellaneou s hardware, tools, labor, equipment and incidentals necessary to complete the work. Portable electric power unit, measured as prescribed above, complete and accepted, which price shall be full compensation for furnishing all equipment and materials, power unit, transformer, attachment devices, remote control unit, all labor and incidentals necessary to complete the unit. Payment will be made under: 683-A: Lighting Assembly, High Mast, * , Type - per each 683-B: Lighting Assembly, Low Mast, * , Type - per each
