Recommendation and Determination to Solicit from One Source or Brand Name

This document recommends negotiating with a single source, Precision Filters Inc., for "Precision Filters Signal Conditioning Chassis Hardware." It justifies this sole-source acquisition by detailing the impracticality of full and open competition.

• The procurement is for "Precision Filters Signal Conditioning Chassis Hardware."

• The estimated lead-time for delivery is 60-90 days ARO (After Receipt of Order).

• The hardware is currently in use across all turbomachinery facilities within ERB.

• Personnel have already received specialized training for this specific equipment.

• Procuring the same hardware ensures full interchangeability with existing systems.

• Allows for the use of common spare parts, mitigating equipment failure risks.

• Transitioning to a different hardware standard would incur significant additional costs for retraining operators and modifying facilities.

• Such a change would reduce operational efficiency and increase the risk of errors.

• Maintaining standardized hardware supports efficient operator training, minimizes lifecycle costs, and ensures continuity of operations.

• The total estimated cost is not specified in the document (indicated as blank).

• Not applicable, as this is a sole-source recommendation.

• Not applicable, as this is a sole-source recommendation.

• The document is dated 2/10/2026.
