PART 3 - EXECUTION

0.1 INSTALLATION

A. Concrete Foundations: 1. Concrete: Use 3000-psi-minimum, 28-day compressive strength complying WITH ASTM C 94, using 3/8-inch maximum aggregate size. Provide reinforcement as indicated.

B. Install poles as follows: 1. Use web fabric slings (not chain or cable) to raise and set poles. 2. Mount pole to foundation with leveling nuts, and tighten top nuts to torque level recommended by pole manufacturer. 3. Secure poles level, plumb, and square. 4. Grout void between pole base and foundation. Use nonshrinking or expanding concrete grout firmly packed in entire void space. 5. Use a short piece of 1/2-inch-diameter pipe to make a drain hole through grout. Arrange to drain condensation from interior of pole.

C. Luminary Attachment: Fasten to indicated structural supports.

D. Luminary Attachment with Adjustable Features or Aiming: Attach luminaires and supports to allow aiming for indicated light distribution.

E. Lamp luminaires with indicated lamps according to manufacturer's written instructions. Replace malfunctioning lamps.

0.2 CONNECTIONS

A. Ground equipment. 1. Tighten electrical connectors and terminals according to manufacturer's published torque- tightening values. If manufacturer's torque values are not indicated, use those specified in UL 486A and UL 486B.

B. Ground metal poles structures according to Division 16 Section "Grounding." 1. Others may install ground rod and ground wire with the base; coordinate with the Owner. 2. Connect ground wire to pole base and bushings in accordance with manufacturer’s installation recommendations.

0.3 FIELD QUALITY CONTROL

A. Inspect each installed unit for damage. Replace damaged units.

B. Tests and Observations: Verify normal operation of lighting units after installing luminaires and energizing circuits with normal power source, and as follows: 1. Check intensity and uniformity of illumination. 2. Check excessively noisy ballasts.

C. Malfunctioning Fixtures and Components: Replace or repair, then retest. Repeat procedure until units operate properly.

0.4 CLEANING AND ADJUSTING

A. Clean units after installation. Use methods and materials recommended by manufacturer.
