This document is an attachment (Attachment 1) to a Statement of Work (SOW) for a by-pass flow system installation at Orwell Dam near Fergus Falls, Minnesota. The U.S. Army Corps of Engineers (USACE) St. Paul District requires a contractor to provide an operational by-pass system capable of maintaining a minimum flow of 80 cubic feet per second (cfs) around the dam control structure during a planned dewatering inspection. The project scope includes supplying and installing submersible pumps, a generator, approximately 350 feet of leak-free piping, and associated equipment, with specific operational parameters: system setup on the north side of the dam, operational from 8:00 am on September 15, 2025, to 3:00 pm on September 19, 2025, with removal completed by September 26, 2025.

Critical requirements include submitting a comprehensive by-pass plan, detailed construction schedule, spill control plan, safety plan, and point of contact information for approval prior to mobilization. The contractor must provide all necessary equipment, including a generator capable of powering the pumps, and ensure continuous flow with the ability to restore service within six hours of any mechanical issues. Additional obligations include environmental protection, adhering to safety protocols outlined in EM 385-1-1, and coordinating equipment placement with government representatives to avoid disrupting dam instrumentation and bulkhead installation.
