The Red Rock Hydroelectric Facility Project successfully converted an existing flood control dam owned by the U.S. Army Corps of Engineers on the Des Moines River in Iowa into a 15,200 SF/63 ft high hydroelectric facility that now provides up to 55 MW of electricity to the communities in its vicinity and an approximate energy output of 178,000 MWh per year. The project started in September of 2011 and was commissioned complete in 2021.
The approximate valuation of the project is $284M and it consisted of key earth retention work such as tie-back anchor installation, diaphragm walls, deep excavations and the treatment of solutioned gypsum deposits.
In 2021, the project won the DFI Outstanding Project Award and the PTI Award of Merit
