Hydroelectric projects are capital intensive high risk projects which are normally safe, but any failure can be catastrophic. Every geotechnical design is to some extent hypothetical, and every construction job involving natural geologic materials such as earth and rock, runs the risk of springing surprises. These surprises can come up at the most inconvenient time adding difficulties which might result in cost and time over-runs. These circumstances are the inevitable results of working with materials created by nature, often before the advent of human beings, by processes which results in non-uniformity.
