Solicitation / RFP / RFQ

This document is a Justification and Approval for Restricting Competition (Part 12) for a brand-name-only acquisition. The US Army Corps of Engineers (USACE), Rock Island District, seeks to award a Firm Fixed Price (FFP) commercial contract for Lubell Labs, Inc. LL 1424 HP Underwater Acoustic Transducers. The estimated value of the contract is $3.8 million, funded by FY2023 Construction General funds. The purpose is to support the Brandon Road Interbasin Project (BRIP).

• Quantity: 280 units of Lubell Labs, Inc. LL 1424 HP Underwater Acoustic Transducers with protective steel housing cages.

• Environmental Survivability: Transducers must operate continuously in harsh conditions of a USACE navigation lock approach channel, withstanding intense water turbulence, impacts from river debris, projectiles from tow boat propellers, and corrosion/damage from environmental extremes.

• Acoustic Performance: Transducers must be omnidirectional, capable of producing over 180 dB across a frequency range of 200 Hz to 8000 Hz to deter invasive species, and operate effectively while overcoming ambient river noise.

• Operational Reliability: Units must be capable of continuous 24/7 operation and have a minimum coating of MIL-C-5541E standards for corrosion resistance.

• Mission-Support Features: Must include electric wet-mate connectors for underwater replacement without removing the entire array, and operate without pressure compensation at depths between 9 and 40 feet.

• Contract Type: Firm Fixed Price (FFP)

• Funding: FY2023 Construction General funds

This document is a justification for restricting competition to a brand-name-only product, indicating that a full solicitation with open competition is not being issued at this time.

This acquisition is restricted to a specific brand-name product (Lubell Labs, Inc.) due to demonstrated unique capabilities and proven performance in the specified environment. No "equal" product is allowed.

• The USACE Engineering Research and Development Center (ERDC-EL) conducted extensive research and testing, confirming that only the Lubell Labs, Inc. LL 1424 HP transducer meets the government's minimum needs for performance and survivability.
• Failure of a single unit is a major operation with significant costs and potential river closure, necessitating extreme reliability.
