Inside a mountain in the Kitimat Ranges on BC’s northwest coast is a 475-metre long, 8-metre wide “tailrace” tunnel that transports the outflow water from the hydroelectric generation station in the mountain. The client, Rio Tinto, required a detailed interior survey of the tunnel for ongoing maintenance purposes and the tailrace could not be shut down for inspection. McElhanney provided bathymetric survey expertise to launch an autonomous drone mission that captured 3D scans of the tunnel interior to provide the client with the high-definition data they required for the structure.
As part of its Transportation Initiatives Projects 2020, the Town of Canmore sought to transform the Benchlands Trail and Bow Valley Trail intersection with multi-modal safety improvements to better protect all road users. This included fully separated facilities for pedestrians, cyclists, and motorists to integrate with Canmore’s existing Complete Streets system and enhance active transportation in the area.
