About this opportunity
The U.S. Army Corps of Engineers Louisville District is soliciting bids for the Cannelton Lock and Dam Lock Interlocks and Dam Encoders Upgrade project, which involves comprehensive modernization of existing miter gate controls, valve controls, and lock operations interlock systems to comply with current Inland Marine Transportation System Interlock Standards. The work includes replacing existing dam tainter gate height position encoders and associated hardware, upgrading proximity sensors, installing new control cabling, and modifying lock control stands across both main and auxiliary lock structures. The project encompasses six contract line items covering instrumentation replacement, control system upgrades, interlock relay installation, and construction mobilization/demobilization activities. This firm-fixed price contract operates under NAICS code 237990 (Other Heavy and Civil Engineering Construction) with a small business size standard of $45,000,000. The solicitation has undergone multiple amendments, with the final bid submission deadline extended to August 7, 2025, at 10:00 AM, and technical inquiries must be submitted through the ProjNet system using the designated Bidder Inquiry Key.
This procurement does not utilize any set-aside designation and is open to all qualified contractors. No incumbent contractors or potential award values are specified in the available documentation, though the contract structure includes detailed price breakout schedules for each of the six construction line items. The period of performance spans one year from August 27, 2025, to August 27, 2026, with a 10-day mobilization period required and liquidated damages of $984 per calendar day for project delays. The work will be performed at the Cannelton Locks and Dam facility located at 5821 E State Road 66 in Cannelton, Indiana (Mt Pleasant, IN 47520). The project requires performance and payment bonds and includes comprehensive technical specifications for upgrading electrical and control systems across 12 tainter gates and multiple valve control systems to ensure improved operational reliability and standardization of the lock and dam infrastructure.
