SECTION 265623 - APRON LIGHTING



This master should be used by designers working on Port of Portland construction projects and by designers working for PDX tenants (“Tenants”). Usage notes highlight a few specific editing choices, however the entire section should be evaluated and edited to fit specific project needs.

C. Luminaire finish shall be corrosion-resistant industrial grey paint.

D. Acceptable products/manufacturers: Wide-Lite A2S-400-A-480, or equal.

3. OBSTRUCTION LIGHTS

A. Furnish L-810 type obstruction lights which meet the requirements of FAA Specification AC 150/5345, “Specification for Obstruction Lighting Equipment.”

B. Luminaires shall be neon tube type lights with single fresnel lens and integral transformer. Acceptable products/manufacturers: Litebeams, Inc., Model No. 5618, or equal.

4. POLES

A. Poles shall be round or octagonal area tapered, minimum 11-gauge steel with a minimum 8-inch diameter base.

B. Poles shall have a minimum 3 inch x 5 inch reinforced handhole with a removable cover.

C. Welded seams or joints which will be visible after complete installation shall be ground so that they will not be noticeable after galvanizing.

D. Luminaire mounting height shall be as shown on the drawings.

E. Design poles to withstand 100 mph continuous wind with 1.25 gust factor without failure or permanent deformation. Base pole wind load design on poles installed with the specified luminaires, mounting brackets, and obstruction lights.

F. Each pole assembly shall include four anchor bolts (each with leveling nut, anchor nut, and washers), galvanized after threading. Bolt size and length shall be as required to withstand design loads. Furnish anchor bolts for pole base attachment to a structural steel plate. Coordinate anchor bolt requirements with structural provisions.

G. Pole and mounting brackets’ finish shall be hot-dip galvanized after fabrication.

H. Provide reinforced pole mounting brackets for floodlight luminaires 180 degrees apart and one 3/4-inch pole top tenon for mounting an obstruction light. Mounting brackets shall accommodate specified luminaire-mounting requirements and accommodate wiring internally.

I. Assembly shall provide means to support all pole riser wiring without depending on the luminaire attachments.

J. Submittals for approval of poles shall include calculations to demonstrate that the complete structure will meet the continuous gust wind loading criteria, and shall also include complete shop drawings of the poles with specified reinforcements and handholes in detail.

K. Acceptable Products/Manufacturers:

1. Type T, KW Industries, Inc., RTSPB30-8.0-11-G-2-SPEC, or equal.

2. Type T1, KW Industries, Inc., RTSPB-40-9.0-11-G-2-SPEC, or equal.

EXECUTION

1. INSTALLATION

A. Poles:

1. Verify, before assembly of poles and luminaires, that exterior finishes are not chipped or otherwise damaged.

2. Assemble pole sections according to the manufacturer’s recommendations.

3. Poles and luminaires shall be completely assembled and wired before erection.

4. Erection shall include the following:

a. Set leveling nuts on anchor bolts with enough freedom to permit leveling pole.

b. Raise pole and set on anchor bolts without slinging. Set anchor nuts only finger-tight before leveling.

c. Level base plates by adjusting nut pairs until pole is vertical, then tighten anchor nuts securely while checking that pole remains vertical. Install anchor bolt/baseplate cover if used.

d. Make wiring splices in handhole, dress wiring, and install handhole cover.

2. LUMINAIRE AIMING

A. Type T floodlights, four per pole, shall be aimed to provide the desired lighting performance per manufacturer’s recommendations. Apron area lighting maintained footcandle (FC) design levels shall be:

1. Horizontal Plane, Grade Level:

a. Minimum 2.00 FC at a distance of 200 feet.

b. Minimum .50 FC at a distance of 250 feet.

c. Maximum .20 FC at a distance of 300 feet.

d. Average 2.00 FC for the area 250 feet out from edge of building side of apron.
