Project 506-21-208 Upgrade and Expand Exterior Lighting RFI’s and Responses

1. The following specification section is missing: 26 08 00 Commissioning of Electrical Systems. Was this section supposed to be included for this project? Yes. Commissioning specifications added as a part of this Amendment.

3. Is there an ICRA requirement for building T9? Information added as a part of this Amendment.

4. Could you provide pictures for the penetration locations, route for conduit, and distances needed to tie new lights into electrical panel RP3 in building T9 for work to be performed on sheet ES 103. The door was locked, and we could not view. A second Site Visit is to be scheduled via an Amendment.

38. Regarding the disconnection and removal of the temporary flagpole lights and supporting electrical equipment:

a. It appears the temporary flagpole lights are being fed from a light pole approximately ten feet away. Should the conduit be removed to this point, or will additional work be required? Please elaborate. Work should be as indicated in note 7. Existing circuit, conduit and all appurtenances should be removed in their entirety.

39. Regarding the extension of circuits from existing pole lighting, there are fire hydrant water lines and likely other services in the ground. Is there a recent GPR survey of this area or will one be required as part of this SOW? There is no recent GPR survey, it is the contractors’ responsibility to do an underground locate prior to digging on the site.

40. Regarding the new pole base specified in Detail 1 on Sheet ES100, would you consider a partial base replacement in lieu of a full base replacement? We believe it would be less intrusive to deconstruct the pole 12” below grade, reforming, and bonding the new section to the older section. No – full base replacement.

41. Regarding extension of the non-switched leg of lighting circuit RS-41, we were not given access inside. Please provide the following information:

c. If so, that circuit is a 24/7 circuit; should we add a photocell to the new L2 type fixture? The part number in the fixtures schedule indicates that a photocell is integral to the fixture.

d. Does the SOW require any aesthetic work (painting, etc) to the new conduit? No, the conduit shall meet the requirements listed in the specifications.

43. What is the bidding assumption for length of extending existing surface mounted circuits? The assumption is that the contractor will perform a site visit and do a take-off based on their findings.

44. What is the assumption for elevation of new wall mounted fixtures when not noted? The elevations are noted or the fixtures are replacing existing fixtures.

45. Do we assume new breakers are needed for new circuits when not noted? Unless new breakers are listed in the work description notes, new breakers are not required.

46. What is the bidding assumption for flag light raceway demo to panel (ES109-note 7)? The assumption is that the contractor will perform a site visit and do a take-off based on their findings.

47. When extending existing circuits on outside of building, is exterior surface mount acceptable?

Surface mounted conduit is expected. On buildings other than the parking deck, the intent is the penetrate the exterior of the building without running conduit all over.

48. Area 3 is underground at building; please explain the intent of notes 19, 20, and 21. The intent for those work description notes is for the contractor to do the work as stated. A site visit will clear up any confusion. A second Site Visit is to be scheduled via an Amendment.

51. Sheet ES103 – Where is new fixture L3 going to be circuited to? No circuit information shown on drawings. The intent is to extend the existing circuit from the wall pack located to the East of this new fixture.

-Is it acceptable to core though the building wall once and run conduit on the exterior of the building for the new L2 light fixtures on building T9? No. The conduit should penetrate at the fixture and be run inside the building.

52. Sheet ES109 – Where is the existing panel that is feeding the flag pole lights to be demolished located? Can you provide an approximate distance of demo? According to another source, the temporary lights are being fed from a light pole near the flag pole. Distances are to be performed by the

53. Specifications – Where is new lighting control required? There are no new devices or notes shown on the drawings. Existing control systems are being re-used. Where new fixtures are indicated, a photocell is integral to the light fixture.
