Attachment 2 Reference Drawings - Fort Randall DTB Seal Supply.pdf

This is a set of technical engineering drawings and record drawings for the Fort Randall Reservoir Powerhouse facility, prepared by the Department of the Army, Corps of Engineers, for the U.S. Army Engineer District in Omaha, Nebraska.

The drawings provide comprehensive design and construction documentation for the powerhouse structure, including detailed plans for draft tube gates, gate assembly and details, lifting beam components, seal assemblies, and various structural elements. The documents include multiple elevation views, cross-sections (labeled as Section A-A through Section G-G), and detailed specifications for critical components such as rubber seals, bolts, springs, and guide rail systems. Key structural details are shown for the existing gate assembly with specifications for replacing rubber seals and painting draft tube gates. The drawings contain extensive notational references, dimensional annotations, and material specifications, with scales indicated as "3 inches = 1 foot" and various detail scales. The drawings reference contract information and include signature blocks indicating design and review approval. These are record drawings created after construction to document the as-built condition of the powerhouse facility.
