The opportunity was posted on April 23, 2026, with proposals due by May 7, 2026, at 3:00 p.m. The performance location is specified as Granite Falls, and the sponsoring agency is the Department of Defense through the W07V Endist St Paul office. The subcontractor must be prepared to mobilize quickly, manage environmental impacts, and adhere to strict operational timelines dictated by seasonal water levels and ecological regulations.
