The US Army Corps of Engineers (USACE) Rock Island District seeks approval for a $3.8 million Firm Fixed Price contract to acquire 280 brand-name-only Lubell Labs, Inc. LL 1424 HP Underwater Acoustic Transducers. These transducers are essential for the Brandon Road Interbasin Project (BRIP) due to their unique ability to withstand extreme environmental conditions in a navigation lock approach channel and deliver specific acoustic performance to deter invasive species. Extensive research and field testing by the USACE Engineering Research and Development Center (ERDC-EL) confirmed that only this specific transducer model meets the stringent requirements for continuous operation (24/7/365) and durability against turbulence, debris, and corrosion. The high cost and operational disruption of replacing failed units ($700k per unit) further justify the sole-source procurement. The transducers must provide omnidirectional acoustic output over 180 dB within a 200 Hz to 8000 Hz range, operate continuously at 75-80 Vrms, and feature electric wet-mate connectors for underwater replacement and operate without pressure compensation at depths between 9 and 40 feet. Market research indicates no other commercial alternative can meet these combined performance and survivability needs, thereby restricting competition as per 41 U.S.C. 1901 and RFO 12.102(b).

This document is an amendment to Solicitation W912EK26QA016 for Brand Name (only) Lubell LL 1424HP Underwater Acoustic Transducers, which will result in a Firm-Fixed-Price Purchase Order. The amendment updates specifications in the statement of work, adds Contract Line Items (CLINs) for Transformer Testing, and includes a CLIN for impedance test equipment. The solicitation is a 100% Small Business Set-Aside for the U.S. Army Corps of Engineers, Rock Island District, requiring military-grade transducers for underwater acoustic fish deterrent systems. Key requirements include specific transducer and transformer specifications, dry and wet testing protocols, and the provision of impedance test equipment. Offers must acknowledge the amendment and include detailed documentation, with award based on the lowest reasonable price. Deliveries are to USACE facilities in Lockport, IL, with partial shipments accepted within 24 months of contract award. The document also incorporates various FAR and DFARS clauses related to small business, labor, and cybersecurity.
