Replacement of earthen dam with roller compacted concrete (RCC) dam:
Developed geotechnical reverse filter designs for emergency repairs of upstream sinkholes.
Performed geotechnical and geologic exploration; seepage, slope stability, liquefaction potential, seismic settlement, design of multiple filters and downstream toe drain system for replacement of dam with new roller compacted concrete (RCC) dam supported on glacial till, alluvium and landslide debris deposits.
Addressed FERC and State Engineer comments on geotechnical designs.
Performed RCC aggregate testing and mix designs.
Currently providing construction observation, materials testing and engineering support for construction.
