Answer: No.

11. Is the Port planning to keep dual arm poles (two lighting fixtures along Embarcadero)?

Answer: Yes

12. Question: Does the Port require full cutoff or cutoff luminaires?

Answer: The Port requires “full” cutoff luminaires.

13. Question: What is the diameter of the arm attachments for each of the bid items?

Answer: The diameter is typically 2-3/8”.

14. Question: What is the dimension of the mounted flood lights post top tenon?

Answer: 2-3/8” X 4”L

15. Question: Does the Port have an issue with light spill outside the roadway?

Answer: Not particularly, the Port’s requirement is to ensure compliance with light level

requirements for roadway lighting only (face of curb to face of curb).

16. Question: In reference to Section B-1 (Street Lighting Specification), item no. 4 and

Section D (Bid Alternate) where it states “Mounts shall not be made of aluminum”.

Does the Port have a preference on the type of mounts and accessories?

Answer: Mounts can be powder coated steel, galvanized steel, or stainless steel.

17. Question: When should shields be required for flood lights?

Answer: If a luminaire needs to tilt to achieve the light level requirements set forth,

shielding will be needed. If the luminaire can be mounted horizontally with no tilt,

shielding is not required. However, if additional shielding enhances the performance of


the luminaire to meet light level requirements, the IES file used in photometric

calculation shall match the necessary shielding.

18. Question: In reference to the AutoCAD file, will a file for the Bid Alternate be available

as well?

Answer: The AutoCAD file will include all bid elements, including bid alternate.

19. Question: Are there photometric calculations required for the backside (sidewalk) fixtures

along Embarcadero?

Answer: No, fixtures facing backside shall not be included in photometric calculation. All

bidders shall conduct calculations using the AutoCAD basemap with luminaires facing

the roadways provided as part of this addendum.

20. Question: Regarding the Photometric requirement, does the Port want photometric

calculations for the fixture alone, installed, or both?
