PROJECT WORK
GEOTECHNICAL
Landrie Lake Dam Safety Review & Geotechnical Investigation, Nova Scotia Department of Transportation & Infrastructure Renewal
Meco completed a Dam Safety Review and Geotechnical Investigation for the Landrie Lake Water Utility near Port Hawkesbury, Nova Scotia.
The reservoir system consists of two embankment dams and a reinforced concrete spillway that form a protected municipal water supply.
The work included:
- Comprehensive dam safety inspection and condition assessment.
- Review of inflow hydrology and recommendation of an Inflow Design Flood (IDF).
- Dam failure modelling and consequence classification assessment.
- Geotechnical investigation including boreholes and subsurface characterization.
- Evaluation of embankment and foundation performance.
- Review of Operations, Maintenance and Surveillance (OMS) procedures and Emergency Action Plans.
- Review of monitoring instrumentation and historical performance data.
This project demonstrates Meco’s expertise in geotechnical investigations, embankment dam performance evaluation, and dam safety assessments for municipal water supply systems.
Dam Foundation Investigation, Halifax Water - Lake Major
Meco was retained by Halifax Water to complete a Geotechnical Investigation to support design development for the Lake Major replacement dam.
The investigation included multiple drilling phases, barge-supported boreholes within the reservoir, rock coring, soil sampling, and permeability testing.
The work included:
- Planning and execution of a comprehensive geotechnical investigation program.
- Soil sampling and rock coring.
- In-situ permeability testing.
- Environmental protection planning and implementation.
- Full-time field supervision and quality control.
- Development of a geotechnical model and interpretation report.
- Foundation recommendations to support detailed dam design.
This project demonstrates Meco’s expertise in geotechnical investigations, foundation characterization, and support of major dam infrastructure projects.
