Ft. Randall Dam

Ft. Randall Dam

About the Project

The Fort Randall Dam is an earth embankment dam impounding the Missouri River in South Dakota, United States and forming Lake Francis Case. It is one of six Missouri River dams, four being located in South Dakota. During the 2011 Missouri River Flood the dam was damaged by debris. The U.S. Army Corps of Engineers soon began repairs to the dam and its spillway gates which KGC played a role in.

Work included visual Hydraulic Steel Structure (HSS) inspection of stoplogs and tainter gates, 3-D modeling and analysis utilizing STAAD. Pro software, non-destructive testing, structural repair design, welding (per AWS D1.5M/D1.5), corrosion repair, abrasive blasting, lead-based paint removal, wire rope replacement, cathodic protection removal and installation, and design and replacement of hoist controls and switches and replacement of existing crane with rehab work on the crane rail system.

QP1/QP2 certification were required.

Abrasive blast cleaned 21 tainter gates to a SSPC SP-5 and applied multiple coating systems to the tainter gates that included 5-E-Z Vinyl.
