Dam and Spillway Safety Inspections and Evaluations

Dam and Spillway Safety Inspections and Evaluations

Hundreds of dam failures have occurred throughout U.S. history, causing immense property and environmental damages and have taken thousands of lives. For non-powered dams, each state is responsible for overseeing dam safety inspections. The Federal Energy Regulation Commission (FERC) oversees and regulates dam safety inspections at federally licensed hydroelectric facilities and requires 5-year inspections performed by Independent Consultants (IC) for dams FERC deems significant or high hazard potential. Kleinschmidt routinely performs dam safety inspections to meet the FERC, state, provincial, and internal owner audits. 

Kleinschmidt specializes in the highly regulated FERC Part 12 Inspection. A Part 12 inspection requires an evaluation of all water-retaining project facilities that may impact public safety if they were to fail, including structures, spillways, gates and foundations. FERC’s analysis incorporates a process called the Potential Failure Mode Analysis (PFMA). A PFMA is an examination by a panel of experts of “potential” failure modes for an existing facility. An additional part of the Part 12 process is the Supporting Technical Information Document that captures the information necessary to have a complete understanding of the dam, as well as any analyses completed that support the findings regarding safety of the structures. 

Our team includes several dam safety engineers, including FERC Independent Consultants. They have combined to complete hundreds of State and FERC Part 12 Inspections throughout the U.S.
