Set to be a landmark for Sejong City, the Geumgang Pedestrian Bridge has a total length of 1,638 meters and spans a width between 12 meters and 30 meters. To ensure the design intent and construction process were aligned, the project team wanted to compare the BIM design data with the on-site works. They tried using third-party software to capture and monitor the project site, but they lacked accuracy and clear visibility.
They selected ContextCapture to generate a 3D reality mesh from images taken of the construction site, including the collapsed slope surface, to determine the restoration works required. Using the models, they were able to quickly identify the exact location of the damaged areas at the site, guiding construction accordingly and resolving the damages. The models can be used for similar works in the future.
