Other / Unclassified

This document is a "Single Source Justification (Simplified Acquisition)" for the "Purchase Cooling Tower FSH B624" project (Purchase Request / Local ID Number: F2M3CB6016A002).

This document explains the rationale for soliciting from a single source, Evapco. The justification is based on:

• Technical Requirements: Evapco is identified as the only manufacturer meeting necessary criteria without compromising system integrity, compatibility, or long-term reliability.
• Salient Characteristics: Specific features like PVC drive eliminators with a drift loss of .001% and type 304 stainless steel basins with factory-welded seams are highlighted. A more detailed list is referenced in an attached document.
• Existing Infrastructure: The current infrastructure and design specifications are aligned with Evapco's proprietary standards, meaning alternatives would require significant redesign, leading to delays and increased costs.

The Contracting Officer has determined, in accordance with FAR 13.106-1(b)(1), that a single source is reasonably available. Market surveillance is being conducted to preclude future single-source awards.
