1. 1 Lighting/Utilities HDM Ch. 12/13

2. 2 Goal: Safe, energy efficient, economical lighting system which will produce the desired visibility

3. Design Steps Locate all utilities (overhead/underground) –Planimetrics (base mapping) –Survey –Utility companies –As-builts Plot utilities on plans, cross-sections & profiles Incorporate utility locations in design Send prel. plans to utilities (conflicts) Utilities will show proposed relocations Incorporate all utility info in PS&E Make sure all utility resolutions and agreements are initiated early 3

4. 4 Lighting Local municipality assumes O&M cost/responsibility Design elements –Light source (lamp) –Luminaire (lamp& reflector) type and position –Mounting Height –Pole offset from traveled way –Electrical design

5. 5 Equipment Luminaire (lamp & reflector/refractor) Luminaire Support ) –Arm (single arm; truss; davit) ( –Pole (aluminum, wood, fiberglass) –Base (breakaway, anchor, direct-embedment) –Foundation CIP/precast or direct embedment (check soils)

6. 6 Typical High pressure sodium (HPS) Common combinations: –150W / 9m height –250W / 12m height –400W / 12-15m height

7. 7 Luminaire Spacing Design guides: –Outdoor Illumination RecommendationsOutdoor Illumination Recommendations –Roadway Lighting Quick SelectorRoadway Lighting Quick Selector http://www.gelightingsolutions.com/ Computer Software Equations; see HDM

10. 10 Handout Design Guides Determine minimum average fcs –fcs (avg foot-candles @ end of lamp life) –Higher numbers mean more light Determine uniformity ratio –(avg/min uniformity) –Defines quality of illumination –Better to have low #’s Determine spacing from “Roadway Lighting Quick Selector”

11. 11 Example 4-lane, collector, commercial (ped conflict high) GE M-400 Prismatic Luminaire 40 ft mount ht; 4-ft overhand 400W HPS Answer –FCS: 0.8 (or greater) –Ratio: 3:1 (or less) –Spacing: approx. 75 feet

12. 12 Collector (high ped conflict): Avg Luminance: 0.8 Uniformity Ratio (Lavg/Lmin=3)

13. 13 3:1 (or less)----Spacing less than 75’ (Controls) & 0.8 fc (or more)----Any spacing will work

14. 14 Electrical Electrical distribution (connection to utility poles) Wiring (size/type) Conduit (galv steel or PVC) Pullboxes (CIP/precast) Junction Box (one for each luminaire) Photoelectric control (individual or central)

15. 15 Lighting Report Light source type Size/mounting height Luminaire type and location Luminaire spacing and arrangement Power supply point Hardware Calculations/computer printouts

16. 16 Lighting Plans & Specs-1/2 Roadway lighting plan –EP,ES, Edge of Curb –Luminaire supports and spacing –Other facilities (conduit, cables, jacking, pole numbering, controller, power supply, and pullboxes) Table of luminaire installation –Luminaire # (correlates to plan) –Location by station –Lateral offset –Foundation elevation –Foundation type –Pole type –Luminaire type and lamp size, voltage requirements –Luminaire mounting height

17. 17 Lighting Plans & Specs-2/2 Wiring details –Circuit wiring –Transformer, base wiring –Controller wiring Pole foundation details –Special installation details for cut/fill –Dimensional requirements for foundation/conduit placement Pole details (general configuration) Misc. details –Limits of clearing and grubbing

18. Miscellaneous Exit ramps---Poles should be located approximately 50m away from the gore area (to avoid being hit) Bridge lighting—Locate poles approx. 25 m to provide light under the bridge (if bridge does not have under-bridge lighting) Signs-poles should be placed >15 m in front of lighted signs or >10m in front of unlighted signs 18

19. 19 Special Lighting High Mast (interchanges/rest stops) –Increased safety/visibility –Light “spillover” –Municipality responsible for O&M Ornamental/Decorative –Considered a betterment and local municipality must pay add’l costs

20. 20 Utilities-Definition: Privately, publicly, or cooperatively owned lines, facilities, or systems for producing transmitting or distributing:

21. 21 Utilities Communications, Power, Electricity Light, Street Lighting Heat Gas, Oil, Crude Products Heat, Steam Water, Stormwater, Wastes Fire/Police Signal Systems

22. 22 Utilities It is in the public interest to accommodate utilities on state ROW

23. 23 General Design Steps Locate all utilities (ovh/ugd) Plot utilities on plans/cross-sections/profiles Incorporate utilities in design Send preliminary plans to utilities Incorporate all comments and resolve problem areas Make sure all utility resolutions/agreements are initiated early

24. 24 Controlled Access Usually no utilities except right-angle crossings Crossings are usually encased

25. 25 Non-Controlled Access Install utilities close to ROW and outside of curb line/ditch line

26. 26 Responsibility Private Utilities –If w/in state ROW, utility owner must pay –If outside ROW, state will pay Municipal Utilities –Reimbursable if relocation required due to construction –Some utilities might be considered a betterment and municipality might have to pay incremental costs
