Additional amendment with remainder of questions and answesrs is forthcoming.

Unanswered questions are included for information with this amendment to acknowledge their receipt in accordance in accordance with the solicitation requirements

Bidders must sign and return a copy of all amendments with their bids.

1. In regards to drawing HA-01 the Project title on the drawing is Building 1 Halls and Walls. I do see it has in red on the top left for Reference Only.

This is for reference but as this project includes demolition of Vending room, the walls right outside that would be lead containing if it is a yellow glazed block.

3. Drawing A-101 please clarify the building numbers on the drawings. Some Reference Bldg 1 some reference Bldg 18. Drawing FX101 References the switchgear Rm as Building One.

Building 1 is the hospital itself. Building 18 is the switchgear room. These two rooms are connected but separated by a wall. For this project, we will be taking down that wall and incorporate the vending room (in Building 1) as part of the switchgear room (building 18).

4. Is Building One and Building 18 the same building?

See question # 3 for explanation.

Is there a video surveillance/access control component to this project

3. Switchgear Room Configuration: Will the new switchgear room be a single consolidated space incorporating the existing vending room and the current switchgear room?

Refer to drawing Sheet A-101. There is a new pair-door in the existing wall between the current switchgear room (Bldg 18) and the new expanded switchgear room (BG000, Bldg 1).

4. Equipment Placement: Will the new switchgear be installed in the vending room, or will the transformers be placed there while the switchgear remains in the existing switchgear room?

Refer to drawing Sheets E-001 to E-603.

5. Space Allocation: Alternatively, will all new equipment (transformers and switchgear) be installed within the existing switchgear room, with modifications made to ensure adequate ventilation and spacing?

Refer to the construction documents.

. Will VAMC Facility Electrical Engineering provide a similar or compatible functional Specification against Siemens-Allie?

It is not required to be siemens equipment but rather any equipment that is equal to equipment within the spec and drawings.

Does the SDVOSB Prime have to be a General Contractor?

This is a Total Service-Disabled Veteran Owned Small Business (SDVOSB) Set-Aside under NAICS code 236220. Contractor qualification determination will be made in accordance with Federal Acquisition Regulations

Does the General Construction phase on pages 50-68 apply to the General Contractor designation as the Prime contractor on this project?

All pages of the contract would apply to the awarded party (Prime).

Is Siemens SENTRON or GEAFOL OEM being upgraded? Is equipment being bid on this project as a Vendor/Subcontractor?

It is not required to be siemens equipment but rather any equipment that is equal to equipment within the spec and drawings.

Do the VAMC Switchgear and Transformer Upgrades have similar OEM (Siemens) specifications in the Bid, or can another vendor's OEM equipment be bid?

It is not required to be siemens equipment but rather any equipment that is equal to equipment within the spec and drawings.

Is the Electrical contractor to replace the existing substation B18-SWGR-Main A/B and transformers B18-XF-T6 and B18-XF only?

Refer to Sheet E-601 for the extent of the demolition. In addition to other work, all distribution equipment including the medium voltage compartments B18-MVS-S6 and S7 and downstream items are to be replaced.

Is it the intention to have the awarded firm provide the newer version of the existing products now under the SENTRON or GEAFOL product lines? If so, why weren't the specifications and model numbers of the newer Siemens Equipment included in the bid?

The equipment is not sole sourced. Approved equivalents are allowed to be used.

Are we to provide a new tie breaker that can properly transfer power without manual load transfer? Has the Siemens Account Representative provided a make and Siemens Product and item number?

Tie breaker is to be kirk-keyed with the main breakers of the transformer secondaries, and manually controlled.

Are we to relocate the distribution circuits to the new switchgear or the former canteen/break room?

Distribution circuits are to be relocated from the existing switchgear to the new switchgear upon energizing, phased in a sequence which is coordinated with the VA so as to be least disruptive and minimize downtime.

Provide a concrete foundation to house the new switchgear in the canteen/break room?

Refer to Drawing 3 GROUND FLOOR NEW WORK PLAN and New Keynote 3 on Sheet A-101 and Detail 7 CONCRETE EQUIPMENT BASE on Sheet A-601.

Questions Regarding Transformer Specifications

Common Types:

- Dry-type transformers: Often used indoors for hospitals due to safety and ventilation.

- Liquid-filled transformers: Suitable for outdoor installations.

- Medium-voltage (MV) transformers: Typically 2.4kV to 35kV.

- Pad-mounted or Substation Transformers: Depending on layout.

Popular Siemens Models:

- Type 550-EE 5974: Likely a legacy or custom spec – Siemens Allis was a predecessor brand, now Siemens Energy.

- New equivalent would fall under Siemens SENTRON or GEAFOL product lines.

Specifications to Know:

- kVA rating (size/load)

- Primary/secondary voltage

- Impedance

- Tap settings

- NEMA or ANSI requirements

Questions Regarding Switchgear

Medium-Voltage Switchgear:

- Air-insulated (AIS) or Gas-insulated (GIS)

- Arc-resistant options available

- Siemens SIPROTEC, NXAIR, or GM-SG lines

Low-Voltage Switchgear:

- Up to 600V

- Siemens WL Series, Sentron, or PowerMod

Hospital/VAMC Special Requirements:

- Redundancy and N+1 reliability

- Remote monitoring (SCADA or BMS integration)

- Seismic compliance and fault tolerance

Drawing EP101 Note 4 says “integral vacuum fault interrupter at transformer”. There is no mention of a vacuum fault interrupter in the Unit Sub specs 261116.

The One-Line on E-602 also does not show a vacuum fault interrupter. Please clarify what is required.

Specification 26 23 00 LOW-VOLTAGE SWITCHGEAR – paragraph 2.6 specifies a Battery System. I don’t see a battery system on the drawings anywhere. Please confirm a battery system is required and where IT would be located.

Drawing E602 Note 2 says provide 60A breaker at Panel EED. However, the One-Line indicates adding a 200A breaker. Please clarify.

Are any of the feeders currently under the slab that need to be extended?

There is a video surveillance/access control component to this project.
