The Challenge: Efficiently Intervening on an Existing Structure in a Sensitive Natural Environment
The rehabilitation of the Three Corner Lake Dam took place in a context typical of aging hydraulic infrastructure, characterized by restricted site access, strict environmental constraints, and the need to intervene without compromising the overall stability of the structure.
The main challenge was to plan and execute targeted corrective work while ensuring crew and public safety, maintaining strict control of water levels, and protecting the surrounding natural environment. All interventions also had to comply with applicable provincial regulatory requirements governing hydraulic structures.
In this type of mandate, precise planning and close coordination among stakeholders are essential to minimize operational and environmental impacts, while ensuring the long-term performance and durability of the infrastructure.
