This amendment clarifies the government's intent regarding:

• Automatic Transfer Switch (ATS) requirements (size, rating, configuration, and amperage).

• Reuse of existing conduit and wiring.

• Generator information.

• Site visit procedures.

• ATS Requirements: The solicitation does not specify ATS size, rating, or configuration. Offerors must propose an appropriately sized ATS based on their technical evaluation, applicable codes, and site conditions. The government has not designated a required ATS amperage, and offerors may propose a rating they determine appropriate, supported by load calculations. Offerors may also propose the ATS configuration (main lug only vs. service entrance rated) they deem technically appropriate.

• Reuse of Existing Conduit and Wiring: The Statement of Work directs the reuse of existing conduit and wiring unless site assessment indicates replacement is necessary for code compliance, safety, or proper integration of the proposed generator and ATS. Offerors must clearly identify in their proposal any required replacement or upgrade of conductors or conduit and provide justification.

• Existing Generator Information: Details of the existing, damaged generator (Onan Model: GGHE 5566742, Serial Number: H020402526, Spec: C) are provided for offeror assessment.

• New Generator Requirements: The solicitation does not prescribe a specific generator make or model. Offerors are responsible for proposing a generator solution that meets functional requirements and complies with applicable electrical and safety standards.

• Site Visit Information: Offerors wishing to schedule a site visit should contact Dewayne French or Jonathan Sanders at 870 625 3912. Scheduling is subject to government approval.

• All other terms, conditions, and attachments remain unchanged and in full force.
