The document is a Justification and Approval for Use of Other Than Full and Open Competition, related to a procurement by the Naval Surface Warfare Center, Carderock Division (NSWCCD). The purpose is to acquire specialized parts to repair the Large Cavitation Channel's (LCC) Water Pump 2 (WP2), specifically a cast bronze liner and two screw shafts. These components are unique and cannot be replaced by standard commercial alternatives. Houttuin Pompen, the original manufacturer, and CIRCOR, the exclusive U.S. reseller, are the only companies capable of providing these proprietary parts, owing to their specialized knowledge and access to original specifications. The justification cites the authority of 10 U.S.C. §2304(c)(1) for limiting competition, explaining that significant delays and costs would result from procuring and installing entirely new pumps. The anticipated repair costs are approximately $300,000, which is significantly lower than the estimated $1.5 million for a complete overhaul. This repair is essential for maintaining operational capabilities at the LCC. The document outlines prior efforts to find alternative sources but emphasizes that the unique requirements of the existing pumps render competition impractical. The justification will be made publicly available for transparency in accordance with federal regulations.
