Sole Source Justification- Nortek_Redacted.pdf

This is a Justification for Sole Source document for a federal contract opportunity under simplified procedures with a maximum procurement threshold (MPT) to $5 million for Small Business Administration (SAT).

The United States Naval Academy (USNA) is procuring one (1) Doppler Velocity Logger (DVL) from Nortek USA, Inc. on a sole source basis without competition. The DVL must meet specific technical specifications including 0.1% long-term accuracy, 0.1/75 meters min/max altitude capability, 0.1 mm/s velocity resolution with 0.8 cm/s single ping standard filter, 8Hz maximum ping rate, 144mm diameter by 158mm height housing, 300-meter depth rating, 4-beam Janus array configuration with 25-degree beam angle, 12-48 volt input voltage, 1.5 amp maximum current, 1.7 kg weight in air, 0.3 kg weight in water, and 1MHz acoustic frequency. The anticipated delivery date is August 15, 2026.

The justification for sole sourcing cites compatibility requirements with existing USNA Weapons, Robotics, and Control Engineering Department systems. Specifically, this DVL serves as a direct replacement/spare for equipment previously purchased under contract N00189224P2226 from Nortek. The contracting officer determined that requiring an alternative manufacturer would necessitate complete system redesign, force maintenance of two duplicate systems with different spare parts, negatively impact mission capability, require additional training and resources, delay deliverable timelines, and compromise research and project-based learning objectives. The document is signed by Cody Witz, Contracting Officer at NAVSUP Fleet Logistics Center, Norfolk Contracting Department, Fleet Directorate.
