Amendment 0002 – Solicitation 36C26126Q1088 Triennial Electrical Inspection Solicitation 36C26126Q1088 Triennial Electrical Inspection Amendment 0002 Questions and Answers Document

1. Where Attachment 1 lists an individual component, such as a circuit breaker, but does not separately list the panelboard, switchboard, switchgear, or MCC containing that component, should the Contractor service only the individually listed component and its associated cubicle/compartment; or perform separate complete maintenance/testing of the parent assembly?

It should just be for individually listed components. However, you will find some strays that should be evaluated as they are sometimes newly installed or changed out due to replacing an existing one. The station’s preference would be to perform separate maintenance testing of the parent assembly on an as needed basis.

2. Where Attachment 1 lists a panel, switchboard, MCC, or other assembly but does not identify its internal devices, should the Contractor perform only assembly-level maintenance, or are all internal breakers, starters, relays, switches, and other devices also required to be individually tested?

At most, most things only include a rating plug on the main breakers. However, the GE air breakers we have would require a more detailed inspection.

3. If the internal devices are included, please provide the applicable quantities and ratings.

Attached Completed Final Report

4. Attachment 2 refers to switchgear, switchboards, distribution panels, MCCs, and “all related components.” Please confirm whether components not individually identified in Attachment 1 are nevertheless included in the lump-sum scope.

Yes. As a lump sum, this is correct. We have too many things and breaker items to be too specific. All should be included, including hardware, screws, covers, etc.

5. Several Attachment 1 records appear to use broad equipment classifications. For example, certain MCC-related loads are identified as Type = “SWITCHBOARD. Please confirm whether the Type column represents the actual equipment type and required test procedure, or whether it is only an inventory classification.

Some parts are used as inventory classification. For example, NDP2 has about 6 breakers on it, all riser breakers. When shutting it off, it is expected to test all breakers and inspect NDP2 as a whole (the bus bars, grounds, neutrals, hardware, casing, etc.). Panel Z has multiple breakers on the panel, each breaker should be tested, and the whole panel itself should be tested and inspected as well.

6. Please provide the latest available:

· Single-Line Diagrams (SLDs) / one-line diagrams;

· panel schedules;

· switchgear/switchboard schedules or elevation drawings;

· MCC schedules or lineup drawings;

· breaker schedules;

· CT/PT information; and

· any existing arc-flash study/model and related electrical system data.

Please see attached documents.

7. Attachment 2 requires all breakers rated 100 A or greater to receive primary-current injection testing. Please provide a schedule identifying all circuit breakers requiring primary injection, including the breaker rating and equipment/location where available.

This information is not available.

8. For panel records with comments such as “42 CB'S,” “28 CB'S,” “35 CB'S,” etc., please confirm that these quantities represent the total number of individual breakers within the panel and that each breaker is required to be individually exercised/tested and documented.

Those numbers indicate how many breakers are in place, sometimes just the number of breakers and not the number of spaces allotted in the panel. If the breaker is under 100A, then simply exercising the breaker, infrared scan, and recording documentation will suffice.

9. For panels where Attachment 1 provides the total breaker quantity but does not provide individual breaker ratings, please provide the quantity and ratings of breakers that are 100 A or greater so the required primary-injection quantity can be determined.

This should be assessed at the panel by a walkthrough. Only because, we do have more than few panels that have improper AIC ratings and that should be changed out. This could be a thing where the VA purchases breakers on our own and provides them to the contractor to install. Our preference is to have all panels match the manufacturer intended ratings.

10. For panel records where Attachment 1 identifies the panel but provides no internal breaker quantity or rating, should the Contractor: perform panel-level inspection/maintenance only; or test all internal circuit breakers?

For anything that no internal breaker quantity is provided, a panel level inspection maintenance should be required. If the item is just the one breaker, then testing the internal circuit breaker should be completed.

11. Attachment 2 requires molded-case circuit breakers, including frame sizes 225 A or less, to be manually tripped and restored, while a separate requirement specifies primary injection for breakers rated 100 A or greater. For breakers rated below 100 A, please confirm the complete required test scope, including whether manual trip/reset and applicable NETA MTS inspection/maintenance are sufficient, or whether any current-injection or additional trip-function testing is required.

Infrared scan and manually resetting each breaker under 100A will suffice. Along with tightened lugs.

12. For each RELAY COMP / Type RLY record in Attachment 1, please provide, where available: number of protective relays and manufacturer/model.

This information is not available from the station.

13. Please provide the quantity and ratios of CTs and PTs/VTs associated with the protective-relay systems and confirm whether CT/PT/VT testing is required as part of this contract.

This information is not available from the station.

14. Please identify the quantity and locations of ground-fault protection systems or devices to be tested and, where available, provide their settings.

This information is not available from the station.

15. The PWS identifies generators, automatic transfer switches, and generator control/synchronization systems as part of the testing scope. Please provide the complete equipment quantities, ratings, and required test scope for these systems where they are not clearly identifiable in Attachment 1.

16. Please identify the quantity and locations of the facility grounding systems and lightning-protection systems that are required to be tested, including any required certification and if there are any loop switches included in the scope.

Only aware of few locations BLD 22 Chiller Plant, BLD 18 Switchgear, and in the OPC basement for grounds installed and lightning protection

17. Please confirm the required quantity basis for infrared scanning. Is IR scanning required once per listed switchgear, switchboard, MCC, panel, ATS, or disconnect assembly, or must each internal breaker, feeder, termination, starter, and bus connection also be separately scanned and documented?

As far as what has been accomplished in the past, the infrared scan was for the wire, the breaker, the terminal boards, the screws/bolts, the MCC, ATS, and disconnect assembly. I don’t recall scanning starters, but we could, for the bucket items.

18. Will the VA coordinate operating/loading conditions so that the applicable electrical equipment is energized and sufficiently loaded during the infrared survey?

Yes. Infrared scans are no issue, as our preference is to not shut anything off we don’t have to.

19. Please provide the anticipated number of planned electrical shutdowns and MOPs required to complete the work and identify, where possible, which equipment or building areas may be grouped under the same shutdown.

All shutdowns will require MOPs. There very well might be more than what I’m about to name, but not much. Not including the mains (BLD 1, OPC, and Emergency), we anticipate at least 10 shutdowns to cover. Here is what makes the most sense to shut down at the same time. The need may change based on facility needs or demands:

i. BLD 2, 22, 25, and 3

ii. BLD 31 can be one day or two, but if the crew is big enough, you can also shutdown

1. LC2 trailers and BLD 34, as each has their own transformer to isolate them.

iii. BLD 18 and 32 can be done together, as they are tied to roughly the same transformer.

iv. BLD 27 and BLD 28 are next to each other. BLD 27 has it’s own dedicated generator. BLD 28 is an extension of our living center and is tied to our main generator system.

v. PNL P and Z are from the radiology branch. This branch is unique in that it’s dedicated to ONLY radiology. This is usually a separate shutdown, usually done on it’s own before the main shutdowns. This requires proper coordination as they see patients all night on the XRAY, CT machines.

b. BLD 1 has multiple shutdowns associated with it. MSSA and MSSB power BLD 1. They cannot both be turned off. They are interconnected with a bus tie contactor. We tend to shut down one side to work on, while the other side powers the facility.

i. EDP1 (ATS1) and EDP2 (ATS2) are separate days. These are the emergency feeds to the hospital. Of note, they go to our patient headboards in our ICU/SCU patient rooms, surgery, emergency lighting, and UPS equipment (including the facility server room). The rest of the normal risers and panels can be done with MSS A and B work.

ii. We also work on our Sub Basement MCC when MSS A is shutdown. That is because it is associated with our medical vacuums, house air, and boiler/HVAC equipment to our facility. This is tied to our emergency power supply, since we are shutting down critical hospital equipment (SPS, medical vacuums, boilers/heating, cooling, etc.), we usually try to move as promptly as possible for that.

c. OPC shutdown usually takes a couple of days. In here, ATS A, B, C, and D are involved, and of great importance is the Emergency Department. I think there are about 5-6 panels in this area that involve the emergency department. Also, the Air Handler equipment that feeds the OPC side of the building (our main building is called BLD 1, floors sub-basement to 7th floor, but the OPC is an extension of BLD 1, and contains floors from the basement to the 3rd floor) will be shutdown for this portion of the testing, making it stuffy in the patient floors. There are electrical closets for each OPC floor (basement to 3rd) and one OPC mechanical space above the 3rd floor.

d. Emergency power. Some of this work can be done with just isolating the generators from powering on the emergency bus. We have a few panels (at least 3 panels and 2 transformers) that I can think of that have no power unless the generators are on. These can be done at any time. As to the main hospital, all ATS’s will have to be looked at and seen by whomever is performing the work to better grasp what is being shutdown. Elevator ATS and panels for example, can be bunched in, but we obviously don’t want them shut down too long because we still see patients throughout the night. We would also have to discuss ANY shutdown to the emergency side of power to the facility. As this will often require back up generators in place to keep specific areas powered up while work is being done on the panels.

20. Can multiple equipment groups or building areas be completed during the same night/weekend mobilization, or should separate mobilizations be assumed for individual shutdowns or building areas?

There will be multiple shutdowns for about 2-3 weeks. We group in as many as we can, but we have multiple power sources and we can’t isolate them all at once as we are a hospital. We tend to shut off about 4-5 risers a night, over about 3 days. This allows for panels to be tested and bigger breakers as well. In testing the main lines, same thing. From there, we have outbuildings and of course the emergency buses and power sources as well. We try out best to accommodate what we can and shutdown as much as possible if there is enough crew and they can handle the workload.

21. CLIN 0002 / Repair Pricing - Please clarify how CLIN 0002 – Repair / Service Work should be priced in relation to the Government's stated $20,000 Demand Maintenance and Repair allowance. Should the Offeror enter a value for CLIN 0002, or is the $20,000 amount intended to be Government-funded separately after award?

The repair CLIN will be labor pricing only. The quote should include the vendor’s estimated labor costs associated with the repair component of this solicitation.

22. Is this a brand new contract OR if there is (was) an incumbent performing these services? If not brand new, could you please provide the current / previous contract number?

There is no active contract in place for these services. Previously the services were provided for under Contract 36C26121P1638.
