Written by GovTribe AI · Aug 29, 2025

These documents are detailed engineering drawings for a Hydraulic Vertical Pivot Gate installation at the Fort Peck Dam in Montana, prepared by the U.S. Army Corps of Engineers Omaha District in March 2025. The project involves installing a new 72-inch high vertical pivot gate with specific technical requirements, including construction options of either steel or aluminum gate materials, a concrete foundation dug to the frost line, and integration with existing chain-link security fencing. The gate will feature pressure sensors to detect obstructions, an automated operator with RF transmitter controls, and a yellow strobe light to indicate gate movement. Additional project elements include installing new conduits, handholes, equipment racks, entry/exit pedestals, and protective bollards around the gate area. The drawings provide comprehensive technical specifications for foundation, gate structure, electrical components, and installation details across multiple sheets (CS501, ES101, ES401, ES501, FA501, EY501).
