TDA Auxiliary Water Supply Backup Debris Management

The U.S. Army Corps of Engineers is seeking information from industry members to determine their interest, capabilities, and qualifications for a Design-Bid-Build construction project. The project involves providing a predesigned mechanical method for dislodging debris from the trashracks at the East Fish Ladder Auxiliary Water Supply Backup (AWSB) system intake. The goal is to remove the need for operations staff to shut down the AWSB system to let river currents clear accumulated debris from the screens. • The project includes pavement repairs, trenching, and the installation of a mechanical equipment system. • The system will be mounted on the upstream forebay structure and accessed from a fixed access platform with a transition to a traveling trolley platform. • The equipment supplier will coordinate the details of the equipment and mounting systems with the Installation Contractor. • The project requires the contractor to occupy sections of the dam access road and may involve working at heights over water.
