Answer: Yes

Question: In a one for one replacement under the canopy area it will be hard to reach the 50FC call out. Would you like to add more fixtures here to meet 50FC? Or, are you okay with having around 40-50 FC under the canopy areas for a one for one replacement?

General Questions:

6. Is there emergency ballast included in the scope of work or do you have an emergency back up generator? This will be significant if we change out a fixture that has an emergency ballast without one. Typically drawing sheets will show this designation with a different code on the fixture, but your drawing sheets were not taken from true electrical drawings. Without this it would be difficult to tell even on a site walk. If your engineer can count or audit which fixtures have them and we can quote the number of emergency ballasts needed for each fixture type per building. Or in some cases the customers realize it is something they can buy and install after the fact. Your engineer would know the best way to go. Without this information all fixtures will be quoted without any emergency backup ballast. If you could get electrical drawings or as-builts in case of changes to upload this would help immensely.

Answer: All fixtures are on generator with no emergency ballasts.

7. Is there a recycling bin provided? Or do we need to obtain our own. We can work with an outside recycling company that many drop off the bins and pickup. And in most cases customers ask for proof of the materials being recycled.

Answer: Contractor is responsible for all recycling and providing documentation to GSA of the total weight recycled.

8. Is there any known asbestos or other safety issues on site we need to be aware of?

Answer: There are no know issues at these locations

Is a bid bond required? No a bid bond is not required.

Will there be a performance and payment bond? No

Will the contract performance time change now that the bid is closing later? The contract performance time will be adjusted but the performance period for this project shall remain 150 calendar days from award of contract to Substantial Completion.
