High Falls Gorge Wall – 3D Laser Scanning Project

Project Story

Fisher performed a 3D laser scan to capture a 3D surface model of the High Falls Gorge Wall used to initiate a monitoring program of rock wall deterioration. This project captured detailed data including anchor bolts previously installed into the rock face for measurement comparisons that might indicate movement from deep within the rock. This new scan model was used to establish a baseline survey of the rock wall using control points and survey baselines from which future scans will be compared to determine rates of deterioration. Monthly precise leveling surveys were completed for one year, monitoring possible settlement of the existing structure located directly above the rock wall.
