Description

Contractor Questions and Answers: Question: We understand that not all ASCO switches will require servicing by ASCO technicians due to the varying testing specs. We were told only (2) 1963 ASCO automatic transfer switches will require ASCO technicians. Can you please specify in writing which of the ASCO automatic transfer switches will and will not require ASCO certified technicians. Answer: All Transfer switches at Bowling must be tested and maintained by an ASCO certified technician. Question: We were also told that Lexington VAMC will be procuring resources to service the (3) onsite Power Generators. Please confirm that Item 17 Equipment, and Scope section 7 page 11 is or is not a part of this solicitation s testing spec. Answer: The Contractor shall preform an oil and coolant sample test of the three existing generators. All associated equipment fed from the Generator should be tested and maintained to NETA and Manufacturers standards. Question: We were also told drawings would be provided for Bowling campus following our site-visit. If they re available, is it also possible to receive the test report for Sousley campus? Answer: Provided, see Amendment 1 under 36C24923Q0376 0001 posted on SAM.gov Question: Can Lexington VAMC provide contact information for the serving utility to discuss service disconnection? Answer: Our Account manager with KU is Joe Pierce, (502) 627-4084. Question: SOW section IR Scanning page 15 repairs to hot spots. As this is an unknown we suggest that it would be better to address this on a case by case basis rather than us estimating a number of these instances into our proposals. Answer: No, per the SOW, it specifically states Infra-Red scan all bus plugs, panelboards, motor control centers, and transformers in the Main, Tower and Chiller building s electrical closets and distribution rooms. An actual count should be conducted and therefore there should be no estimation of a number. Question: For the sake of comparison, can you provide the solicitation documents for the past inspections corresponding to the provided inspection documents at the Sousley and Bowling Locations? Answer: No, however the base scope of the requirement has not changed from the prior solicitation to the current solicitation. Question: The solicitation says to service all its components at 2 addresses, but the drawing provided also references other building # s and does not include all equipment in the test report. The SOW also says an inventory list is included but an inventory list was no included. The only documents provided with equipment info are the one-line and 2021 test report. Is the equipment list in the report comprehensive and can it be used for pricing (Main Hospital, Tower Bldg, Chiller Plant)? Answer: See Inventory Equipment List as attachment to Amendment 2 under 36C24923Q0376 0002 posted on SAM.gov Question: Equipment SOW clarifications: Manholes and Medium Voltage Cables they are not listed in the SOW or reports. Please confirm they are not part of the SOW. Answer: Contractor must follow NETA standards regarding these cables. Question: Equipment SOW clarifications: Medium Voltage Switchgear Batteries - I do not see these listed in the summary of work paragraph 3.C. Do these require service and is a load test required? No load testing will be required. Answer: All other NETA standards should be followed. Question: Equipment SOW clarifications: Automatic Transfer Switch the SOW states they must be serviced by an ASCO technicians, but it doesn t look like ASCO was used for the 2021 SOW (no ASCO certifications or reports). Can a NETA certified technician provide this service or can you break it out form the SOW if ASCO is required? Answer: This is only needed for the ASCO transfer switches at the Bowling facility. Question: Equipment SOW clarifications: Liquid Filled XFMR s the SOW says to replace fluid if it no longer meets manufacturers specification. Please confirm this is not part of the preventative maintenance and would be handled on a time and material basis. Answer: The intent of the SOW is to ensure the liquid level is maintained to meet manufacturer s recommendations. Question: Equipment SOW clarifications: Lightning Protection the SOW says it must be certified in accordance with UL 96A. I do not see this requirement in the 2021 test report. Is this required? Answer: Yes. Question: Equipment SOW clarifications: Panelboards / Dist. Panels what is the SOW? Answer: Infrared scan is required and all breakers exercised. Question: Equipment SOW clarifications: Busway is this infrared scan only? Answer: Yes. Question: Equipment SOW clarifications: MCC and starters what is the SOW? Answer: Please see page 9 of SOW.

Answer: Any breaker with a trip unit should be tested. Question: Clarification to WFS- (4-hour Power Outage Test) I don t see a generator load test specified listed in the 4-hour test. Is this required? If so, please provide specifications and the # of generators that require a load test. Answer: The VA will handle the load bank test during the outage. Question: Clarification to WFS- (4-hour Power Outage Test) I can t include utility fees unless we have a quote from them or hourly rates and the # of techs provided. Answer: Our local utility for both sites is KU and contact information can be provided if needed. Question: Clarification to WFS- (4-hour Power Outage Test) Calibrations are excluded but we can assist with troubleshooting up to thru 12 hours (max) listed Answer: See page 4 of SOW. Question: Do you need us to make any settings adjustments for the updated coordination study that Astute will provide? Answer: Yes, when deemed necessary by the COR. Question: We will not schedule the utility for any outages or the 4-hour outage test. Answer: The VA can assist with contacting the local utility personnel. Question: Will outages be performed on Saturdays and Sundays? Answer: Yes Question: 4-hour Power Outage test are we required to pay the utility for these services? Answer: Our local utility for both sites is KU and contact information can be provided if needed. Question: Are there any outage constraints or can we work full 8-hour days? Answer: Our local utility for both sites is KU and contact information can be provided if needed. Question: Who will develop the PM schedule for the VAMC equipment? Answer: See page 2 of SOW. Question: Who will provide 480V, 3P, 100A for our primary injection test set? Will we have access to this power requirement at all locations or will breaker need to be transported for testing? Answer: The contractor will need to provide. 480 volts is not available at all buildings.

Answer: Yes, the disconnects on the line side of the elevator controllers and the connections to the elevator controllers, but not machines are to be included in the inspections. Question: Best practices for Infra-red Scanning is to remove all equipment covers, dead front covers and to expose as many points of connection and lengths of conductors as is practical. Is this what is required to the Infra-red imaging, or are breakers permitted to be scanned by only opening the door of panels? Answer: No. Dead fronts must be removed. Question: At the site walk, it was stated that during the 4-hour power outage, load bank testing of the generators was completed in the past, is this required to be included in our scope of work. The solicitation does not call out any load bank testing. Answer: Load bank not required Question: Pg. 4 of the solicitation calls for a NETA certified contractor or equivalent certifying organization.
