Ko-Mapper was tasked with modeling a water and sewerage structure to investigate the cause of the sinkage of the two-lane road above it and verify movement of the underground infrastructure. They previously used traditional methods for surveying structural displacement. However, given the limited accessibility to the survey area, these strategies decreased data reliability. They needed a comprehensive reality modeling solution to accurately capture and process the data and images into a high-resolution reality mesh.

Ko-Mapper selected ContextCapture to reconstruct 1,200 aerial images and laser-scanned point clouds into an accurate digital twin, which they delivered to the owner for managing the structure. Using Bentley’s application resulted in a 1-millimeter accurate model of the water system structure and surrounding area that will be used to perform an objective assessment of the exterior condition and displacement, as well as manage the structure’s shape.
