Attachment 3 - Questions and Answers – B542 new UPS Installation

Question #1 (multiple): Is there a loading dock or ground-level access? Is a liftgate needed to get the new unit off the truck? How far from the building entrance/loading area to the actual install location? Any tight corridors, stairs, or elevators involved?

Answer #1: For the installation of the new UPS, the building has ground-level access and the UPS itself is within 5 feet of the entry door to the building. There are two bricks steps at ground level to walk up to enter the building. For the location a lift gate would make removing the new equipment from the contractor’s vehicles easier and loading the old units as well. A vehicle could be driven within 10 feet of the entry door to the building, so the removal of the old UPS and installation of the new UPS would only require less than 20 feet to walk. No tight corridors or elevators involved with only 2 brick steps to travel up.

Question #2: Is there a freight elevator if it's not on the ground floor?

Answer #2: No freight elevator needed, as previously identified.

Question #3: Any escort/badging requirements to get on base or into the specific facility that add wait time?

Answer #3: Badges are an option for contractors. If they have them they won’t have to be escorted on base but contractors without will have to be escorted. Badging requirements can be addressed post-award.

Question #4: Is the existing hardwired electrical work compatible as-is for the new UPS?

Answer #4: Yes, the existing hardwired electrical work is compatible as-is for the new UPS.

Question #5: Does start-up include connected-load testing, or just power-on self-test?

Answer #5: Start-up also includes connected-load testing.

Question #6: Does "removal and disposition" mean off-site to a scrap/recycling vendor, or just relocate within the building?

Answer #6: Yes, "removal and disposition" means taking the units off-site to a scrap/recycling vendor.

Question #7: Weight/size of the existing 9155, is it a single frame or does it have external battery cabinets too (more to disconnect and haul out)?

Answer #7: The current UPS takes up an approximate 4’ by 4’ square foot area including the battery backups. The UPS has two external battery cabinets that would also require disconnection and removal.
