The Department of Defense, specifically the U.S. Army Corps of Engineers (USACE) Engineering Research and Development Center – Coastal and Hydraulics Laboratory (ERDC-CHL), intends to award a sole source contract for the procurement of forty analogue output capacitance wave gauges. These specialized instruments are critical for laboratory operations, providing highly linear performance and sub-millimeter accuracy across a wide range of water levels and temperatures, which are essential for seamless integration with existing systems. The sole source supplier, Akamina Technologies, Inc., is uniquely qualified to fulfill this requirement due to the proprietary nature of their instrumentation system, which ensures compatibility and reliability. Interested parties may submit capability statements to Angela Holcomb at Angela.D.Holcomb@usace.army.mil, but this notice does not constitute a request for competitive quotations, and the government retains discretion over the procurement strategy.
