Pre-Proposal Offeror Questions and Government Responses QJVF 14-0031, Replace Highbay Lights Multi Bldgs

FA4528-17-R-0003

Attachment 7 20 April 2017

1. Drawings issued #1-8 and 12 non numbered sheets. The descriptions on the drawings do not match the building. Could you please attach the building number to the sheet to identify the drawing? Example sheet #2 is noted at Repair Lighting Youth Center Bldg 455. I think this is Bldg 455 but not the youth center. I have no idea what sheets 3-7 refer to.

See revised drawings for change in sheet #2 Building number. Sheets 3-7 have facility number located on bottom right of the sheet.

2. Sheet #8 shows lighting control. Most of the drawings and job walk referred to motions sensors and not lighting controls that would call for new conduit and wiring to each light to allow the 0-10V wiring. This is a major scope increase if lighting control, scenes and such are needed. Given the work is high to the lights, to the decking would be significant. Is this Lighting change out with new motion sensors only? Does this sheet refer to another building or project since we did not look at any of the existing lighting controls. Is this for the Youth Center?

Sheet #8 omitted in revised drawings.

3. None of the existing drawing call out the exact height to the bottom of the existing lights. This is critical to light levels so can we get the height of one typical light in each building?

The government will provide, see revised drawings.

4. New drawings needed will be only for layout with Photometrics and not full design drawings correct?

Photometrics will be all that is required to determine sufficient lighting levels in one for one fixture replace.

5. Are the backrounds for layout being given on CAD or another design program?

Basic floor plans are provide for all buildings that they are available for.

6. Time for construction is noted at 128 days currently. We feel that due to occupied areas will require timing and scheduling, a more realistic time frame of 365 days is more realistic. Will that time frame be adjusted?

The period of performance will now be 270 days.

7. Where is a laydown-Storage area for us to use?

Parking area for storage trailers can be provided within reasonable proximity to construction areas.

8. Will a complete set of detailed as-builds for all buildings be provided?

All As Built information is attached with project drawings.

9. Will a floor plans be provided depicting room numbers, floor layout and fixtures to be replaced? This was unclear during walk as some areas overlap others.

See revised drawings.

10. Will exit lights be required to be battery back-up and what style will they need to be?

The scope of this project does not include exit lightings.

11. Is a lighting control system to be provided for each building/lighting system? If so what functionality should they cover? This was unclear during walk as some fixtures are a 1 for 1 change out and ceiling sensors would not be a good application.

See revised drawings. No changes anticipated except building 455.

12. Is post operating and instructional class time is required for this scope as depicted in specification? If so for what specifically and what buildings to cover.

Yes they are required see submittal register to see which section they apply.

13. What are the equipment/weight restrictions for building #455- inside gym floor areas?

Total weight, machine, operator, and load not to exceed 4,500 lbs, when a lift is used on the floor system that the floor should be protected with at least two layers of ¾” thick clean protective sheathing with overlapping seams. Protective material should include suitable clean sheathing and floor finish protections such as red rosin paper.

14. What are the weight restrictions on each and every floor system installed?

Building 455 GYM is the only area of concern.

15 Please confirm there is adequate access for large equipment to reach heights of 40-50 feet will be able to enter bldg. #455-gym area?

Gymnasium has exterior doors that open to a height of 7ft and a width of 8 ft.

15. Please provide bldg. #455-gym lighting control direction with number of zones and possible dimming required?

Zones are labeled A, B, and C on drawings, dimming is not required.

16. Please provide bldg. #455- track lighting direction and controls needed for elevated track area in gym. This was unclear during walk as the gym sensors close by might become activated unnecessarily.

Sensors only over gym equipment areas on second floor.

17. What buildings require only a 1 for 1 fixture change out?

Every building will require 1 for 1 change out.

18. Who is removing and replacing the protective netting of fixtures in building #867? If the contractor is responsible please provide written direction.

Contractor will remove/open and replace/close netting as necessary.

19. Please confirm fixture install for new lights in bldg. #545 is to replace existing fixture heights.

Confirmed.

20. Please confirm if the requirement for “testing wire spools” and getting “approval of such” before ordering as stated in spec’s, applies to this scope?

No section 26 05 19.10 10 – 3.2 does not apply to the scope of this project, but product data submittals will still be required per paragraph 3.1 of this section.

21. Please confirm if the warranty coverage for fixtures and the warranty “on-call” service response time (code #1) stated in specs applies to this project or not?

This section does apply.

As defined on Page 5 of Section 01 78 00 Code 1 (2) applies only to Security lights.

22. What buildings get occupancy sensors?

The second floor equipment areas of Building 455.

23. What are the operational intentions of each building in regards to segregation of circuits/ occupancy sensors ect?

Use existing circuits.

24. What Buildings receive lighting control panels?

None see revised drawings.

25. What buildings require daylight/ bi-level sensors?

None see revised drawings.

26. What outdoor lighting systems are to be considered part of the scope of work? Please provide details.

None see revised drawings.

27. What level of electrical design is the Government looking for?

Photometrics will be all that is required to determine sufficient lighting levels in one for one fixture replace.

28. Will the Government provide the existing drawings in auto cad to assist in the design?

Basic floor plans provided.

29. There are exposed ceiling in this facility. Are we required to paint conduit to match the existing surroundings?

Only in Building 455 if there is any exposed conduit.

30. Drawing 2 of 8 says Youth Center 286 in lower right corner of drawing. This should only be Wellness Center Building 455 See revised drawings.

31. The existing lighting does not have lights over the track. In order to control the lighting over the track there we would have to add new lighting over the track where there currently is none. If this is not your intent we would use the lights for the gym to provide lighting over the track as currently is being done. Please clarify your intent for track lighting.

Provide new lighting for track area and put these fixtures on occupancy sensors as specified in revised drawings and specifications.

32. We would like to know if there is a double wide door into the gyms so we could get a lift into the gym as the ceilings are to high for a lift that would only fit into a single door.

Gymnasium has exterior doors that open to a height of 7ft and a width of 8 ft.

33. Note 2 on page 3 of 8 (Building 545) states only 3 foot candles. Is this supposed to say 30 foot candles?

See revised drawings.

34. Pages 5 of 8 and 6 of 8 both say they are for building 867. Is one of them supposed to be building 837 and are both building identical.

Drawing 5 of 8 is labeled as 867 and drawing 6 of 8 is label 837, see revised drawings.

35. The hangers have netting to keep the birds out. Who is responsible for the removal of the nets and reinstalling them so the lighting can be replaced?

Contractor will remove/open and replace/close netting as necessary.

36. Please clarify the height of the existing lights from finish floor so we can calculate the required light to provide required footcandles.

37. Page 7 of 8 (building 970) does not show the lowbay area we went into located off the west of the facility. Can we get some drawings showing this addition to the hanger?

Low bay area will not be include in the project.

38. We would like to get electronic plans for the building including architectural so we can get some accurate measurements of rooms and heights of ceilings. The PDF drawings for the other project are not very clear and I would like to get them in electronic form. There were no existing as built drawings or drawings showing the requested foot candles for areas included in this solicitation. No drawings whatsoever have been provided with the solicitation for this project.

Basic floor plans in DWG, format provided with a fixture height (see question 36).

39. Do you have a condensed lamp/fixture type and count that you can provide? I'm trying to source it and I just want to cross my t's on all of the numbers.

See As Built Drawings.

40. Can you please provide a clearer copy of the As-Built drawings provided for this RFP? The I cannot read the information in the ones provided due to low quality. Specifically, pages 9-20.

All available as builts provided in highest quality see new attachement.

42. Can you please provide the fixture schedule and wiring / conduit schedules from the as built documents that describe as-built fixtures and existing wiring types?

Fixture schedules provided in as-builts.

43. At the site visit a question was asked about installing LED lamps in existing fixtures instead of replacing the fixtures, Jeremy said this would be acceptable. This contradicts the specifications that reads:

1.1.1.1 Remove existing lighting system in building and perimeter area.

1.1.1.3 Install new LED lighting fixtures in building and perimeter area according section 26 51 00 and 26 56 00.

44. Can we get some clarification on this for both projects?

Due to issues with performance retrofits will not be considered at this time, please plan on replacing the fixture.

45. Building 545 has high bays and strip fixtures in the vehicle area. I assume we are replacing the high bay fixtures and not replacing the strip fixtures. Is this correct?

Correct, only high bay fixtures.

46. Also the lighting in the office at Area E and the strip lighting above it were not lined out in REV 2 but I did not think those were included. Please clarify if they are since they are not high bays.

Only high bay fixtures.
