Attachment 3 - Fort Randall DTB Seal Drawings.pdf

These are technical architectural and engineering drawings for the Fort Randall Reservoir Powerhouse facility prepared by the Department of the Army, Corps of Engineers. The drawings serve as record documentation for the draft tube gates assembly and details, powerhouse structure, and associated mechanical systems at the Fort Randall Dam project in South Dakota.

The drawings include comprehensive construction details for multiple components: half elevations of draft tube frames and hoisting devices, gate seal assemblies with top, side, and bottom configurations, anchor bolt details, lifting beam specifications, guide roller mechanisms, and gate hook details. Additional sheets contain plan views showing pavement items, reference curves, and structural sections (labeled A-A through G-G) depicting the powerhouse layout, draft tube positioning, and gate assembly integration. The technical specifications address materials including structural steel components, rubber seals with specific hole patterns, spring assemblies, and various mechanical hardware. The drawings indicate existing gate assemblies that required seal and paint replacement, with detailed dimensions provided in multiple scales (ranging from full size to reduced scales noted as inches equals one foot). These are construction record documents used to memorialize the engineered design and fabrication specifications for the powerhouse facility's operational infrastructure.
