Tender: Driedmeat Lake Outlet Apron and Fishway Structural Assessment and Repair Recommendations

About

Consultant needed to assess the Driedmeat Lake outlet apron and fishway, evaluating overall condition and structural integrity and providing recommendations for repair, rehabilitation or replacement. The study must include a detailed evaluation of the deteriorated concrete apron—assessing the extent of concrete deterioration, the effectiveness of ongoing repairs and the potential presence of voids beneath the structure—and an assessment of the fish ladder, with particular attention to deteriorated steel components to identify structural deficiencies, maintenance requirements and repair options. The investigation is preferred to be carried out in late fall under low-flow conditions when no water flows over the weir to maximize access to critical structural elements, noting there may still be some water flowing through the fish ladder even when the gate is closed; the consultant should plan an inspection method that accounts for these conditions.
