k_ CITY OF SANTA ANA <br /> E. Field Verification: Lighting manufacturer shall supply field verification of environmental light control <br /> using a meter calibrated within the last 12 months: <br /> 1. Spill verification: Illumination levels shall be taken in accordance with IESNA RP-6-22. The light <br /> sensing surface of the light meter should be held 36 inches above the playing surface with the <br /> sensing surface horizontal (for horizontal readings) or vertically pointed at the brightest light bank <br /> (for max vertical readings) <br /> 1.4 COST OF OWNERSHIP <br /> A. Manufacturer shall submit a 25 year Cost of Ownership summary that includes energy consumption, <br /> anticipated maintenance costs, and control costs. All costs associated with faulty luminaire <br /> replacement-equipment rentals, removal and installation labor, and shipping -are to be included in <br /> the maintenance costs. <br /> PART 2—PRODUCT <br /> 2.1 EXTERIOR ATHELETIC LIGHTING SYSTEM CONSTRUCTION <br /> A. Manufacturing Requirements: All components shall be designed and manufactured as a system. All <br /> luminaires, wire harnesses, drivers and other enclosures shall be factory assembled, aimed, wired <br /> and tested. <br /> B. Durability: All exposed components shall be constructed of corrosion resistant material and/or <br /> coated to help prevent corrosion. All exposed carbon steel shall be hot dip galvanized per ASTM <br /> A123. All exposed aluminum shall be powder coated with high performance polyester or anodized. <br /> All exterior reflective inserts shall be anodized, coated, and protected from direct environmental <br /> exposure to prevent reflective degradation or corrosion. All exposed hardware and fasteners shall be <br /> stainless steel, passivated and coated with aluminum-based thermosetting epoxy resin for protection <br /> against corrosion and stress corrosion cracking. Structural fasteners may be carbon steel and <br /> galvanized meeting ASTM A153 and ISO/EN 1461 (for hot dipped galvanizing), or ASTM B695 (for <br /> mechanical galvanizing). All wiring shall be enclosed within the cross-arms, pole, or electrical <br /> components enclosure. <br /> C. System Description: Lighting system shall consist of the following.- <br /> 1. Galvanized steel poles and cross-arm assembly. <br /> 2. Non-approved pole technology: <br /> a. Square static cast concrete poles will not be accepted. <br /> b. Direct bury steel poles which utilize the extended portion of the steel shaft for their <br /> foundation will not be accepted due to potential for internal and external corrosive reaction <br /> to the soils and long term performance concerns. <br /> 3. Lighting systems shall use concrete foundations. See Section 2.4 for details. <br /> a. For a foundation using a pre-stressed concrete base embedded in concrete backfill the <br /> concrete shall be air-entrained and have a minimum compressive design strength at 28 <br /> days of 3,000 PSI. 3,000 PSI concrete specified for early pole erection, actual required <br /> minimum allowable concrete strength is 1,000 PSI. All piers and concrete backfill must bear <br /> on and against firm undisturbed soil. <br /> b. For anchor bolt foundations or foundations using a ;pre-stressed concrete base in a <br /> suspended pier or re-enforced pier design pole erection may occur after 7 days. Or after a <br /> concrete sample from the same batch achieves a certain strength. <br /> 4. Manufacturer will supply all drivers and supporting electrical equipment. <br /> a. Remote drivers and supporting electrical equipment shall be mounted approximately 10 <br />
