B--Notification of Sole Source Acquisition of Services to Perform Hydraulic Modeling and Evaluation of the Maple River Aqueduct Roughness Elements.

The contract involves performing physical hydraulic modeling using a flume model to study roughness elements within the proposed Maple River Aqueduct. The primary goal is to identify the appropriate size and placement of these roughness elements to achieve optimal flow velocity conditions that support fish passage, while also ensuring the flow requirements necessary to mitigate flood risks for the overall project are met. This modeling work is critical for balancing ecological considerations with flood control measures. Issued by the Department of Defense office in Saint Paul, Minnesota, this sole source acquisition falls under the NAICS code 541380, which pertains to engineering services. The contract was announced on April 22, 2015, and targets specialized expertise to carry out the hydraulic evaluation and modeling necessary for the aqueduct project. The work will contribute to informed decision-making regarding the aqueduct's design to maintain environmental and safety objectives.
