PROJECT WORK
DAM SAFETY
Lake Geraldine Dam Safety Management Plan, City of Iqaluit
Meco was retained by the City of Iqaluit to undertake four primary dam safety initiatives for the Lake Geraldine Dam system, including preparation of a Dam Safety Management Plan (DSMP), Operations, Maintenance and Surveillance (OMS) Manual, Emergency Response Plan (ERP), and a comprehensive Technical Analysis and Risk Assessment.
The Lake Geraldine system consists of multiple concrete and embankment structures that provide the primary water supply for the City of Iqaluit.
The work included:
- Comprehensive dam safety inspections and condition assessments.
- Development of a Dam Safety Management Plan.
- Preparation of Operations, Maintenance and Surveillance procedures.
- Preparation of an Emergency Response Plan.
- Instrumentation review and installation of monitoring equipment.
- Numerical modelling for seepage, stability, and temperature performance.
- Seismic assessment and structural review.
- Potential Failure Modes Analysis (PFMA).
- Hydrotechnical modelling to evaluate flood capacity and reservoir performance.
This project demonstrates Meco’s expertise in dam safety management, risk assessment, and regulatory compliance for critical water supply infrastructure.
Macal River Dam Safety Review, Fortis Belize
Meco was retained by Fortis Belize to complete a Dam Safety Review (DSR) for three hydroelectric facilities located along the Macal River in Belize: Chalillo Dam, Mollejon Dam, and Vaca Dam.
The facilities consist of concrete gravity dams constructed using a combination of roller-compacted concrete and conventional concrete, with dam heights ranging from approximately 23.5 m to 67.5 m.
The work included:
- Review of historical reports, design documentation, and previous analyses.
- Evaluation of dam failure consequences and consequence classification.
- Assessment of inflow hydrology, flood routing, and freeboard adequacy.
- Comprehensive site inspections and interviews with operating personnel.
- Review of design and construction adequacy.
- Assessment of spillway capacity and dam stability.
- Preparation of a comprehensive Dam Safety Review report.
This project demonstrates Meco’s experience in dam safety reviews for large hydroelectric facilities and complex concrete dam structures.
