About this file
This document is a Request for Information (RFI) Questions and Responses file for the Tomah VA Medical Center (VAMC) Electrical Switchgear Replacement project. The solicitation (IFB 36C25225B0007) involves replacing electrical switchgear, generators, transformers, and associated electrical infrastructure at the facility. Key details include a project requiring temporary generators, power shutdowns limited to 4 hours, and specific requirements for equipment procurement and installation.
The RFI contains 17 pages of technical questions and responses from potential contractors, covering topics such as generator specifications, power load requirements, commissioning processes, equipment lead times, and site-specific installation details. The VA will utilize a "Limited Notice to Proceed" (LNTP) strategy to manage long lead time equipment, with 30-day submission and review periods for pre-construction submittals. The project is set aside for Service-Disabled Veteran-Owned Small Businesses (SDVOSB) with a 25% labor participation requirement, and the anticipated award is expected 2-4 weeks after bid opening, with construction start within 2-3 weeks of award.

1.1 12.26.24
1.1 amend 1 40 e601_RFIQuestions.pdf Can you provide clarification/specifications for the connection panel with manual transfer switch on drawing E601? I have reviewed the specifications and cannot find any section that provides guidance on this. See attached drawing with red outline.
PCG
It is a load bank and connection box for a backup generator in case maintenance needs to be done by VA on new generator in Rm 107. To be located on northwest exterior wall. Will add language to drawings for clarification.
2/26/2025
2.1 12.27.24 The scope of the project will require the electrical power be shut off to the building for demolition and new equipment installation. Is there a seasonal time of the year when this shut down could be performed without an impact to the VA facility? If so, how many days or weeks would the VA facility allow this facility to be out of commission?
COR/PCG
No. This boiler plant runs continuously. The boiler plant cannot be shut down for more than 4 hours.
Temporary generators should be in place before shutdown occurs.
2/26/2025
2.2 12.27.24 Lead times will vary greatly on the electrical equipment. The MDP or Transformer could have a 46-to-100-week lead time. Is there an expectation to place this project into a long-term suspension for equipment procurement?
COR
The VA will complete a “Limited Notice to Proceed” (LNTP) after award. The LNTP will require the GC to only submit pre-construction submittals related to the material with long lead times. The GC will have 30 days to submit all submittals related to long team times and then the VA will have 30 days to review. Once the VA has reviewed and approved, the GC shall order these material. Once lead times for each item is provided, the VA will suspend this contract (if appropriate). The VA will then lift the suspension when the timing makes sense to then do “full NTP” and enter the second preconstruction phase. The GC will have 30 days in the second preconstruction phase to submit all other preconstruction submittals and the VA will have 30 days to review.
2/26/2025
2.3 12.27.24 With the design intent to be that there is one Distribution Panel for the facility, would we be able to utilize a short full facility shutdown to transfer power?
COR
Yes, no more than 4 hours.
2/26/2025
2.4 12.27.25 The drawings indicate to provide two temporary generators capable of meeting existing power load needs, but there is no indication of a requirement for minimum fuel tank size on board the temporary generator. Is there a minimum onboard fuel requirement?
COR
No requirements listed. This is something the GC must determine and provide.
2/26/2025
2.5 12.27.26 The drawings indicate an 800-gallon fuel requirement for storage on site. Does this include the capacity of one or both generators to reach the 800-gallon requirement?
COR The intent is this 800-gallon tank is the minimum. 2/26/2025
2.6 12.27.27 Would the VA accept two larger sized temporary generators that each exceed the 800-gallon requirement in leu of a temporary fuel tank being stored on site?
COR
One of the temp generators will be running continuously while the other is in standby. How this is accomplished is to be determined by the GC.
2/26/2025
2.7 12.27.28 Does the facility have an estimated load capacity needed when the temporary generator is in use? PCG Yes, the generator is adequately sized for sequence of operation of boilers.
2/26/2025
2.8 12.27.28 Will the VA be assigning a commissioning agent or will the GC be required to provide? COR
The GC is not required to hire a CxA – however, they are required to have manufacture representatives for all Cx items on site during commissioning.
The VA is required to hire our own that will represent the VA for this process.
2/26/2025
2.9 12.27.28 Is a Commissioning Agent already procured for the project? COR No – this will not happen until after this contract is awarded.
2/26/2025
2.10 12.27.28 Does the VA have an estimated duration the GC should allot for commissioning? COR Every project is different – No estimated time. 2/26/2025
2.11 12.27.28
Per the drawings, the VA is requiring the ATS and Generator be from the same manufacturer. The only vendor that can provide an ATS (limited sizes) and a Generator by the same manufacturer, is Cummins. This would be a “sole source” requirement. This solicitation does not include a “sole source” justification document that lists the government’s reasoning why only Cummins would fulfill a “unique technical specification or a lack of viable alternatives”. This precludes the governments’ ability to ensure it is paying a “reasonable price” and endangers the government due to a single manufacturer’s proprietary software. This statement on the drawings, if allowed, will preclude a competitive procurement of alternative manufacturers, capable of fulfilling the specifications, and could possibly be procured sooner than the specified Cummins equipment. Will the government concede on this requirement for the same ATS and Generator manufacturer so long as the supplied equipment is commonly available, widely used for this purpose, and sufficient sized to properly distribute power in the intended design?
COR
The VA is asserting that multiple products will meet the VA’s technical requirements for this contract.
2/26/2025
3.1 12.30.24 EP102 and E601 Are (2) separate 200amp generators enough power to run the boiler plant if only one is running at a time? PCG This will be addressed. Will be changed to (1) 400A disconnect
2/26/2025
3.2 12.30.24 EP102 and E601 Sheet EP102 shows the new service main on the outside of the building. Sheet E601 shows the new service main in new panel MDP-1.
Should the main be in MDP-1 or outside the building?
PCG
The service main will be on MDP-1. The outside main will be deleted.

16.1 2.27.25 Referencing 2.7 In order for us to know what size temporary generators we need to supply for the project, we need to know the size electric load those generators will need to supply. It’s not just the load of the boilers, it’s everything in the boiler plant plus anything else that building is feeding.
PCG
Sheets E601 and E602, which are the one-lines and panel schedules, indicate the loads for the entirety of the boiler plant.

My thoughts on the transformer placement are the transformer. Move the transformer away from the building about least 3’ then the old loop wires running to either Building 428 or building 403/402 can be reused. New ends would have to be installed after cable is repulled because the old ends would have to be removed to get the cable in and out of the conduit.
