The document outlines the Navy's justification for awarding a sole-source contract to Mirion/Canberra for preventative maintenance on their specialized radiological counting systems at the Portsmouth Naval Shipyard (PNS). The contract, valued at approximately $425,895, is necessary to maintain critical equipment that ensures compliance with health and environmental standards crucial for Navy operations. The Navy's reliance on Mirion/Canberra stems from the proprietary nature of their equipment, which does not allow third-party maintenance, thereby preventing competitive bidding. The justification emphasizes that switching vendors would require extensive validation and testing, posing significant risks to the shipyard's operational license. The contracting officer is required to ensure fair pricing through a thorough price analysis. A notice regarding this justification will be published on the appropriate government platform to maintain transparency. Ultimately, the summary reflects the Navy's imperative to ensure operational continuity and compliance with regulatory standards, justifying the absence of broader competition in the procurement process.
