Sources Sought / Intent to Sole Source Cummins products For the Upgrade Facility Generator Control Construction Project 585-23-103 at the Oscar G Johnson VA Medical Center 325 East H Street, Iron Mountain, MI 49801 36C25226B0003 SCOPE OF WORK PART 1 General Scope of Work: This project includes upgrading the control system for three (3) Cummins 1250kW diesel powered generators. This entails installing modernized PCC3.3 Controllers at each generator, replacing the legacy Digital Master Controller (DMC) with Cummins modern DMC 8000, and installing new control wiring to the MV switchgear. A temporary 480V generator (1000kW minimum) and 480V/13.8kV step up transformer will be needed to maintain backup power availability to the Facility. Additionally, to complete the upgrade to the DMC8000 V3.3 software, fifteen (15) communication cards in existing facility ATS units will need to be upgraded and programmed for operation. Period of Performance will be 430 calendar days from the Notice to Proceed (NTP) PART 2 SOURCES SOUGHT GENERAL DESCRIPTION: The Oscar G. Johnson VAMC is requesting sole-source approval for materials to replace existing generator controls utilizing components and software provided by Cummins. The Facility is currently at risk as the generator controls system for the Facility s three (3) Cummins generator sets are no longer supported by Cummins. These controls are required not only to monitor and measure power, but they are also integral for Emergency Electrical reporting required by the Joint Commission. Cummins components and programming are proprietary to the Facility electrical distribution, control, and monitoring. It is critical that this system perform flawlessly as it is part of the EPSS (Emergency Power Standby System) that provides emergency power to the medical center and produces Joint Commission reports. Our existing Cummins generators were installed between 12 and 15 years ago as a multi-million-dollar project in which Cummins was selected as part of a competitive bid. The Cummins equipment needed to complete this controls upgrade would include but not necessarily limited to a new Cummins Power Group Digital Master Control 8000 enclosure with associated hardware, Cummins DMC 8000 Version 3.3 system network controls software, Cummins DMC 8000 Version 3.3 generator controllers with cabinets, and Cummins Automatic Transfer Switch network communication cards. To maintain proper operation of the generators and remain in compliance with the requirements set forth in NFPAs 99 and 110, it is in the best interest of the Government to acquire the proprietary equipment from Cummins to support the completion of the controls upgrade. Work is assigned to NAICS 238210 Electrical Contractors and Other Wiring Installation Contractors. This industry includes businesses primarily engaged in the installation and maintenance of electrical wiring, equipment, and systems.

SOLICITATION 36C25226B0003 AMENDMENT A0002 March 17, 2026 Project: Upgrade Facility Generator Construction Project Number: 585-25-103 Location: Oscar G Johnson VAMC Hospital Amendment 0002 hereby incorporates the following clarifications/change(s) into the solicitation package. RFI Questions RFI Response - Upgrade Facility Generator Construction 36C25226B0003 585-25-103 Date CONTRACTOR QUESTION REFERENCE VA RESPONSE 2/16/2026 Clarification on the period of performance time length from the NTP Information on Bid Schedule is correct. (430 calendar days from NTP) 2/18/2026 After review with MJE chief engineer there is some concern using a Delta to Wye stepdown transformer as a step-up transformer. Using this configuration would create an un-grounded 13.8KV Delta source. This would appear to not be equipped with code-required monitoring. Would a Wye to Wye transformer be an acceptable alternate? This would allow the 13.8KV side of the transformer to be grounded at H0. These also are more commonly available for rental. Drawing EP101, Keynote 16, specifies 3 - #3/0 15kV MV cables, shielded with concentric neutrals to be used in addition to a #3 THHN EGC. The tape shields on the #3/0 cables provide a grounding path for bonding between equipment the Generator 13.8KV switchgear as well as the transformer. Fault current clears through the primary side (480V) system which would be the primary path for fault clearance from the generator. All tape shields and ground conductors from both primary and secondary sides will be bonded at the transformer ground and ultimately also bonded to the XO of the primary wye. A fault clears through the primary wye connected to the temp generator breaker. Keynote 21 requires a x 10 copper rod to be driven into the ground by the temporary transformer. The interior of the enclosure shall be bonded to this rod which would act as a redundant fault path. If a Wye-to-Wye transformer is more readily available, it is acceptable. Please note that the switchgear is configured in Delta, so there is no neutral bus in the switchgear, only a ground bus. The concentric neutrals and tape shields would then be bonded to the switchgear ground bus and transformer high side XO. 2/19/2026 In the solicitation there is no box checked under VAAR 852.219-75. Is this solicitation for General Construction or Special Trade Construction (or Services)? The major materials for this solicitation are specified, but their origin is unknown. Could the Contracting Officer please list the applicable excepted materials, or indicate None per FAR 52.225-9? 852.219-75 page 27 52.225-9 Page 19 Page 27 Inserted "X" Page 19 Inserted "None" See attachments 3/10/2026 In Part 2, it states that the Cummins equipment required for the controls upgrade includes, but is not limited to, a new Cummins Power Group Digital Master Control 8000 enclosure with associated hardware, Cummins DMC 8000 Version 3.3 system network controls software, Cummins DMC 8000 Version 3.3 generator controllers with cabinets, and Cummins Automatic Transfer Switch network communication cards. We intend to quote ComAp controls for both the generators and the DMC, so I want to confirm whether non Cummins controllers will be accepted as part of the bid. Lastly, to ensure an accurate proposal, we would like to perform a brief site visit to gather some additional information. Would it be possible to have a technician stop by on Monday in the late morning? The phrase "is not limited to" is included because there may be additional Cummins equipment required to complete the project than what is listed. It does not mean that equipment from additional manufacturers is authorized. No, additional site visits will be scheduled at this time.
