Post-flooding inspection of sanitary and storm water sewers

Because of the flooding that recently affected Québec, Can-Explore’s Earth division was mandated to inspect the sanitary and storm water sewers in the Ahuntsic and Pierrefonds boroughs in Montréal. Such a post-flooding inspection was required to assess the impacts of the Rivière-des-Prairies overflowing on the structural integrity of the infrastructure in question. The work, spread out over several weeks, involved Can-Explore inspecting 18 kilometres of sanitary pipes in the two boroughs.

Photogrammetry surveys of the Saguenay river shoreline for the city of Alma

During a six-day survey, Can-Explore logged over 20 hours of flight time and travelled 436 linear kilometres to gather topographical information to update the city of Alma’s database. With this information, Alma can more efficiently manage the Saguenay river’s water level by comparing it with that of Lac-Saint-Jean.

Cooling tower of a thermal power plant

In order to inspect two cooling towers located on the East Coast of the United States, Can-Explore deployed a 2-day team to perform drone and 3D scanning surveys. In order to model the two structures more than 141 meters high and 90 meters in diameter, 3340 photos were taken by the drone deployed on the ground. Thanks to the combination of drone and 3D scanner technology, Can-Explore was able to establish a spatial and temporal reference of structural defects and a verticality study.
