Performance Based Surveillance

Abstract [en]

Surveillance is an important risk management and control component of any dam safety program. Due diligence requires all dam owners to maintain surveillance on their water retaining and appurtenant structures. Present practice at BC Hydro, Canada, involves a three level program of inspections, instrumentation data analysis, and design reviews. Typically, instrumentation used for monitoring the structures is the instrumentation inherited from the construction stage. However, this instrumentation is designed for monitoring the construction process, which is not always similar with instrumentation that is required to give first evidence of poor performance. There is a growing awareness within the dam safety community that surveillance activities should be performance based and keyed to failure modes. The main purpose of the Performance Based Surveillance (PBS) project is to optimize the surveillance of BC Hydro dams and appurtenant structures by focusing inspection and monitoring activities specifically on indicators of potential failure modes. The development stage of the project process include: • Reviewing Failure Modes and Statistical Data on dam failures. • Reviewing practice of other Organizations. • Reviewing BC Hydro experiences in Failure Modes and Effects Analyses. • Create a document for a preferred dam, "Good Design and Construction Practices". • Develop draft procedure for Performance Based Surveillance. • Reviewing the past performance of the first pilot dam, earthfill embankment, (reports, drawings). • Comparing the specific dam to the hypothetical "Good Design and Construction Practices". • Search for Potential Weaknesses. • Preparing for Failure Mode and Key Parameter Identification as well as Surveillance Measures. When the failure modes and associated key parameters for each specific dam have been identified it is possible to identify the existing surveillance gaps, and optimize the surveillance program for that dam.
