Project summary

Collins Engineers was tasked with inspecting and designing the rehabilitation of the iconic Stone Arch Bridge in Minneapolis, ensuring that it remains a valuable asset. With its age and size, they faced challenges when developing repair plans that traditional data collection could not accommodate. They used reality modeling previously, but it lacked the quality required for inspecting and modeling complex structures. To collect sufficient data and accurately model the bridge, they needed an integrated survey, modeling, and inspection solution.

Collins Engineers selected ContextCapture to generate a high-fidelity 3D model from over 13,000 images, improving quantity and quality of data. Using iTwin applications facilitated real-time model access, saving 20% of field time. The solution is expected to save 10% to 15% in construction costs due to improved project and bid data. They will use digital twins throughout the bridge’s lifecycle for future planning and maintenance decisions.
