RFP Reference (Sect/Para/Page) QUESTION GOVERNMENT RESPONSE

1/9/2018 1 I read through the solicitation and it appears that you are only looking for new fixtures. What is installed at the location currently?

The current fixtures in the work bay are 13 high bay LED fixtures and 9 high bay Metal Halide fixtures installed that must be removed in the process of this project and any unutilized conduit and wire must be demoed back to the source.

1/10/2018 2 I would like to know the building dimensions + heights.

The dimensions of the rectangular engine shop work bay are approximately:

122ft in the x 62ft with 28ft to the roof deck at the edge of the building and 30ft to the roof deck at the peak.

It is also approximately 24ft to clear the bridge crane that runs the length of the building.

There is also a two story office structure in the north west corner of the bay that is 27ft of the 62ft measurement and 15ft of the 122ft dimension that will not need the high bay LED lights above it and will not need to meet the lighting specification for this space.

1/10/2018 3 Do you have a specific LED High Bay lights fixture that has been quoted by Government? If yes, can you please provide that information?

We do not have a specific LED High Bay Light fixture quoted or in mind. We are allowing the bidders to submit a bid including their LED High Bay Light fixture that meets the specifications and requirements listed in the solicitation.

Pre-Bid RFI Log for W912L6-18-B-6001 Engine Shop Lighting

1/10/2018 4 We have to remove 13 LED and 9 MH, total 22 each.

The quantity of a new LED fixture will be similar (22 each)?

The quantity of fixtures is not limited to the existing number of fixtures as long as the performance and product specifications are met. The contractor will be responsible any power that needs to be run to the new fixtures.

1/10/2018 5 The shop will be empty so the contractor will be able to more around the lift?

The engine shop will be at a minimum of 35% empty with a clear path the length of the building(approximately 122ft).

1/10/2018 6

I would like to know if the site visit is mandatory.

Please let me know if we have to pre-register for site visit (I mean to submit our information ahead, so when we get there to have quick access thru the gate).

The site visit is not mandatory in order to submit a bid.

However, it can provide a great way to view site conditions prior to bidding as all bidders will be held to the same standard of work as listed in the solicitation whether they come to the site visit or not.

You do not need to pre-register. Just show up at the gate with a valid ID that meets Federal Standards i.e. any ID that would work to board a plane will work. The ID will allow you to get a visitor's badge. We will then go to the gate to escort all prospective bidders on base for the site visit at the same time.
