Attachment 3, Questions and Answers, Solicitation UPS Battery W911RX-24-Q-0008 (BLDG 896)

Q1. Do you need a quote just for the UPS or you need the panels boards and their circuit breakers as well?

A1. The quote needs to include the complete removal of the existing UPS to include, if necessary, existing hard-wired electrical wiring if not needed or not being used for the replacement UPS. The quote also needs to include the complete install of new UPS to include using existing hard wiring, existing UPS electrical breaker panel, and the existing UPS bypass panel. If the contractor chooses not to use the existing hard wired electrical infrastructure, they shall install the electrical infrastructure required to include installing an UPS bypass.

Q2. We need to know an exact kVA rating and battery runtime preference. Also, helpful would-be information regarding whether the unit will be hard wired or plug-in as well as a listing of output outlets if that is known.

A2. Exact kVA of replacement UPS should be 6kVA with at least 30 minutes of battery runtime.

The existing unit is hard wired, and the new unit shall be hard wired. The vendor can use existing UPS electrical breaker power panels or install a new UPS electrical breaker power panels if necessary. Reference picture:

Q3. What is the required output rating of the requested UPS? 6 or 9 KVA?

A3. 6 kVA; scalable to 9kVA.

Q4. Can the new UPS equipment be delivered to a staging area near the installation location?

A4. The new UPS can be delivered to a staging area, but it will not be close to the installation location. The installation location is on a ridge that is only accessible through cow pastures and farmland via farm road. The staging area will be 634 Canyon Road on Fort Riley which is approximately 10-15 miles from the installation site. Reference pictures below:

Q5. Does the government have standard dock facilities and/or equipment to off load a heavy pallet from a large truck, or will inside delivery be required?

A5. The delivery location of equipment, if shipping equipment, is a warehouse. The government does have equipment at the warehouse (forklift, pallet jacks) to offload a heavy pallet from a large truck. The location of the warehouse is different from the installation site. The contractor will be escorted to the install location but needs to find a method to transport the equipment from its delivery site on Fort Riley to the install site.

Q6. If inside delivery is required, please provide detailed information regarding any obstacles that will need to be negotiated, such as stairs or narrow doorways less than 36" wide. If applicable, please provide the approximate distance from where the requested equipment will be off loaded and the final delivery or staging location. Please elaborate about any possible difficulties in moving the equipment inside the building.

A6. The equipment cannot be shipped to the same location where equipment installation takes place. Reference the pictures shown in the answer for question four (4). The installation location is a small building enclosed with a high chain link fence on the top of a ridge accessible through farmland.

Q7. Can you provide the serial numbers for the existing UPS system? It is a 10-digit alpha number typically located on the front or back of the UPS.

A7. EB304T0027

Q8. Can you provide a photo of the inside of the UPS cabinets or provide a count of existing batteries or power modules in the current system?

A8. Yes, see below:

Q9. Can you provide a model number for the maintenance bypass so that we can confirm it is compatible with the new UPS configuration?

A9. The make/model of the UPS bypass is not documented on the device. Following are a series of pictures:

Q10. Can you provide the SKU number of the UPS Eaton PW 9170+ Series 6-9kVA?

A10. No, there is no existing SKU on the device.

Q11. Can you tell us what the runtime is?

A11. UPS must provide 30 minutes of battery runtime.

Q12. Site Visit: Would the government host a site visit? This would allow the contractor to review the work area, understand the full scope and the government’s expectations thereby eliminating ambiguities. We have numerous questions about the SOW.

A12. Yes, the government can host a site visit. A site visit is scheduled for 4 Dec 2023, at 9:00

AM.

Q13. Panel Outages During Work Hours: Are panel outages allowed to occur during normal working hours, or do they need to be scheduled outside of these hours?

A13. Power outages are allowed during normal working hours. Our organization plans to use an on-site generator during the existing UPS removal phase and the new UPS installation phase.

Q14. Low-Volt Cable Demolition: Who will be responsible for the demolition of the low-volt cable for the existing UPS? Will this be handled by an in-house team or is it expected to be part of the contractor’s scope?

A14. If the low-volt cable removal is required, then it is part of the contractor’s scope.

Q15. Use of Existing UPS 100A Branch Panel: Will the contractor be able to utilize power from the existing UPS 100A branch panel? Are there any recent assessments or studies that can provide assurance on its capacity and reliability?

A15. The contractor can use power from the existing 100A branch panel. There have not been any recent assessments or studies that can be provided regarding its capacity or reliability. The branch panel is currently in use and there are no existing problems.

Q16. Phasing of Work: It is likely that the demolition will take place on day one and re-installation on day two. Is that feasible for the government? Systems may be without power during this period.

A16. Removal of existing equipment on day one and re-installation on day two is feasible. The government plans to use onsite back-up generator power during removal and install.

Q17. Disposal of UPS and Batteries: Does the government want these items left onsite, moved to a government disposal facility at Ft Riley, or for the contractor to remove and dispose of UPS/batteries?

A17. The contractor is responsible for all aspects of removing and disposing of the UPS equipment and batteries.

Q18: In reference to Technical Specifications, paragraphs 1. l, please clarify exactly what is required in the statement that says; The vendor must ensure the NEC witnesses UPS installation and testing.

Who or what is NEC witness?

A19: The COR

Q19: Does the government require and additional testing other that what is provided by the manufacturers' required onsite testing and commissioning services?

A19: The contractor shall ensure all end devices/equipment that receive electrical power via the new UPS remain powered on during a commercial power loss test after the new UPS is installed.

Q20: Technical Specifications, paragraphs 2. b states: The UPS is to be load tested after batteries have been fully charged by equalizing.

Will this test require the contractor to provide a load bank to perform this test?

A20: No, a load bank is not required; however, the contractor needs to make sure that all end devices/equipment that receive electrical power via the new UPS remain powered on during a commercial power loss test after the new UPS is installed.
