Bradley Engineering Ltd. specializes in high resolution photogrammetric modelling of hydroelectric infrastructure. The 3D models document visual and spatial condition at the sub-millimeter level and serve as a baseline for comparison with future models. The models are comprehensive, documenting fine details of the entire structure that are not captured in a traditional inspection. The models allow specialized experts to complete detailed assessments in an office environment. Use cases identified for the 3D models include inspection, training, education, identification of as-built and current conditions, deterioration and trend analysis, and planning. The ultimate goal of the 3D models is to provide information to improve decision making that could lead to several benefits including reduced lifecycle spending, reduced risk of failure, increased asset performance, and extended service life.
