Special Specification 6363 LED Roadway Illumination Assembly

1. DESCRIPTION

Furnish, fabricate, and install roadway illumination assemblies with light-emitting diode (LED) lamp modules.

An LED roadway illumination assembly is the complete assembly of the light fixture, LED light source, lens, pole, power supplies, components and mounting and other hardware constituting a complete and structurally sound lighting unit.

2. MATERIALS

Use new materials conforming to the details shown in the plans and the pertinent requirements of the following Standard Specification Items:

Item 416, “Drilled Shaft Foundations,” Item 421, “Hydraulic Cement Concrete,” Item 441, “Steel Structures,” Item 442, “Metal for Structures,” Item 445, “Galvanizing,” Item 449, “Anchor Bolts,” Item 616, “Performance Testing of Lighting Systems,” Item 618, “Conduit,” and Item 620, “Electrical Conductors.”

2.1. Submittals. Furnish 2 sets of submittals of the illumination assemblies with luminaires, poles, bases, and all mounting hardware to the Engineer at the project address. Do not purchase materials or begin work before these submittals are approved.

2.2. Poles. Fabrication plants that produce roadway illumination poles, including luminaire arms, must be approved in accordance with DMS-7380, “Steel Non-Bridge Member Fabrication Plant Qualification.” This includes fabricators of aluminum roadway illumination poles and luminaire arms. The Materials and Tests Division maintains a list of approved fabrication plants of roadway illumination poles.

Do not provide shop drawings for complete assemblies that are fabricated in accordance with this Specification and the details shown on the plans. Electronically submit shop drawings in accordance with Item 441, “Steel Structures,” for optional multi-sided steel pole designs; optional aluminum pole designs; and non-standard designs, required when basic wind speeds or pole base mounting heights at the installation locations are in excess of those shown on the Roadway Illumination Pole (RIP) standard. Manufacturers may request that the Department add their submitted shop drawings and design calculations to a pre-approved list of optional and non-standard pole designs, maintained by the Traffic Safety Division.

Hot-dip galvanize fabricated pole sections and associated parts in accordance with Item 445, “Galvanizing.”

Punch or drill holes in steel parts or members, when allowed, before galvanizing.

When shown on the plans, paint poles in accordance with the plans for uncoated structures and in accordance with Item 445, “Galvanizing” for galvanized structures.

2.3. LED Luminaires:

2.4. Performance Requirements. Photometric data must be certified by manufacturer's laboratory with a current accreditation under the National Voluntary Laboratory Accreditation Program for Energy Efficient Lighting Products. Provide photometric data (in .ies format) for luminaires at specified color temperature and operating at 25°C ambient temperature. Ensure the fixture will be IESNA cutoff or better.

2.5. Warranty. The manufacturer will replace failed luminaires, when non-operable due to defect in material or workmanship, within five years of installation with a luminaire that meets all specifications, delivered to the project location. Photocells (if used) are subject to the warranties of their respective manufacturers.

3. CONSTRUCTION

Perform work in accordance with the details shown on the plans in accordance with the manufacturers’ requirements and the requirements of this Item. Permanently mark roadway illumination pole base plates, at a visible location when erected, with the fabrication plant’s insignia or trademark.

Use established industry and utility safety practices when installing poles or luminaires located near overhead or underground utilities. Consult with the appropriate utility company before beginning work.

Prevent scarring or marring of poles, luminaire arms, and luminaires. Replace damaged components. Repair damaged galvanizing in accordance with Section 445.3.5., “Repairs.” Repair damaged painted areas of a roadway illumination assembly in accordance with Item 441, “Steel Structures” or Item 445, “Galvanizing.”
