806.03 CONSTRUCTION.
Attach a safety cable to access doors that face downward and that support the weight of all or part of the ballast. The safety cable shall restrict the amount the door may swing open to 90 degrees. The cable shall be attached to the door by spring clips that can be removed without the use of tools, to allow the door to be easily removed.
806.03.01 Arm Mounted Luminaires. Adjust socket positions to provide the required photometric performance. Provide an individual photocell on each luminaire when specified.
806.03.02 BridgeA structure including supports erected over a depression or an obstruction, such as water, highway, or railway, and having a track or passageway for carrying traffic or other moving loads, and having an opening measured along the center of the roadway of more than 20 feet between undercopings of abutments or spring lines of arches, or extreme ends of openings for multiple boxes; it may also include multiple pipes, where the clear distance between openings is less than half of the smaller contiguous opening. For lengths, all dimensions shall be parallel to the center line of the roadway. The dimensions of handrails will not be taken into account in measuring bridge lengths. Any bridge or highway grade separation structure includes the connecting highways, substructure, superstructure, roadway approaches, entrance plazas, interchanges, overpasses, underpasses, and other structures which the Administration may deem necessary together with all property rights, easements, franchises, and interests acquired by the Administration for the construction and operation of the bridge. Underpass Luminaires. Adjust socket positions to provide the required photometric performance.
806.03.03 Cleaning. Prior to the 30-day performance test, clean refractors and reflectors with a product approved by the manufacturer.
806.03.04 Installation. Furnish and install all luminaires and lamps in conformance with the manufacturer’s recommendations or as 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.
806.03.05 Luminaire Photometric Data and Calculations. Submit the following data with the catalog cut for the luminaire.
(a) Photometric Data. A photometric file for the luminaire selected, in standard IESIlluminating Engineers Society electronic format. Clearly indicate the name of the file on the catalog cut.
(b) Photometric Calculations. Printouts of the predicted lighting levels for the areas indicated 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. If no areas are indicated, select a typical section of the project for each type of luminaire. Assume a maintenance factor of 0.64 for the calculations.
Calculations for roadway luminaires shall show predicted horizontal footcandle values and veiling luminance ratios for the section selected.
For pedestrian luminaires, show calculations for a typical section of walkway. If any of the walkway is adjacent to a roadway, select a section adjacent to the roadway. The printouts shall show predicted horizontal footcandles for the section of walkway selected, and horizontal footcandles and veiling luminance ratios for the roadways adjacent to the walkway. If roadway lighting also illuminates the adjacent walkway, include the roadway lighting luminaires in the calculations.
For proposed changes to luminaire models during the course of the ContractAny agreement entered into by a procurement agency for the acquisition of supplies, services, construction, construction related services, architectural services or engineering services.Contract does not include: Collective bargaining agreements with employee organizations or agreements creating employer employee relationships, as defined in Article 64A, Section 15A(a)(3), Annotated Code of Maryland, Medicaid, Medicare, Judicare, or similar reimbursement contracts which user eligibility and cost are set by law or regulation., or if the manufacturer changes specifications for the luminaire during the ContractAny agreement entered into by a procurement agency for the acquisition of supplies, services, construction, construction related services, architectural services or engineering services.Contract does not include: Collective bargaining agreements with employee organizations or agreements creating employer employee relationships, as defined in Article 64A, Section 15A(a)(3), Annotated Code of Maryland, Medicaid, Medicare, Judicare, or similar reimbursement contracts which user eligibility and cost are set by law or regulation., submit photometric calculations and diskette for each change.

Apply an additional factor of 0.9 for Luminaire Dirt Depreciation (LDD), to obtain a total maintenance factor of 0.64 for calculations. Provide a luminaire mounting height of 40 ft with light centers directly over the edge line of the roadway. Assume four poles in a straight line, parallel to the roadway, spaced at 180 ft each. Perform calculations for illuminance and luminance based on a R3 class pavement. The calculation grid shall be based on a two lane road with 12 ft lanes and shall be placed between the center two poles. Calculate two lines of points for each lane. The first and the second line of calculation points shall be 4 ft from the left and 4 ft from the right lane lines, respectively. Start each line of calculation points directly under the second luminaire and continue every 20 ft until directly under the third luminaire. Each line shall have 10 points, and a total of 40 points shall be calculated. To be acceptable, the average maintained illuminance of all 40 points shall be 0.9 ft candles or greater with an average to minimum uniformity ratio no greater than 4 to 1.
