PUBLIC SAFETY & RISK MANAGEMENT
Consequence Classification & Risk Management System, SaskPower
SaskPower retained Meco to develop a spreadsheet tool to assess dam safety risk and guide SaskPower’s standard of care in providing capital funding and operation, maintenance, and administrative budget allocations.
The spreadsheet tool was comprised of: an inventory of all structures in SaskPower’s portfolio of dams (including routine design and construction information); an updated dam classification system considering consequences internal to SaskPower (i.e. first-party losses); catalogues of design assessments, physical condition, and operational reliability; a data gap analysis; and a risk assessment adapted from the “Risk Index Method” presented at the 2008 Canadian Dam Association (CDA) conference.
The project had 4 main components:
- Compile an inventory of all structures in SaskPower’s portfolio of dams, including pertinent information about the design, construction, and physical condition of each structure;
- Develop an updated dam classification system that accounts for first-party losses, in addition to the third-party categories outlined in the CDA Dam Safety Guidelines;
- Review existing risk assessment methods used in the dam safety industry, and establish a methodology to be used in the spreadsheet tool; and
- Develop a user-friendly, robust spreadsheet tool that will provide insight as to which structures pose comparatively greater risks to dam safety and how those risks can be reduced.
Dam Safety Management System and Gap Analysis, New Brunswick Power
According to the CDA Guidelines, a DSMS “provides a framework for dam safety activities, decisions, and supporting processes.”
In 2015 Meco developed a Dam Safety Management System (DSMS) for NB Power to assist them in managing the dams at their seven hydroelectric facilities and four water storage locations. This included a five year plan with budget estimates to bring all of the facilities in line with current practice.
Meco worked closely with NB Power to develop the Policy for Dam Safety Management which was adopted by both Management and Operations departments as a guide for the Dam Safety Program. Meco then prepared a DSMS which described all the necessary inspections, public safety around dams risk assessment, communications, emergency planning, document retention and supporting processes, as outlined in the CDA Guideline.
Finally, the Gap Analysis was performed to identify any shortfalls and develop a five year plan with specific actions and budget estimates leading to a comprehensive safety system. The work was prioritized using a risk based approach in partnership with NB Power, to suit their risk tolerance.
