Landslide with geological fault, Antioquia, Colombia.
Problem: Recurring Landslides
During each rainy season, for a period of years, a landslide would completely block a section of road that connected two towns in Antioquia, Colombia. Each year the government will bring in heavy machinery to clear the road, but a long-term solution was required.
Solution: UAV based photogrammetry
Fly North was hired to provide precise information on the area of interest. By using a fixed wing UAV we were able to cover 40Ha (approximately 99Acres) that covered the landslide and its surroundings. After only three days the 3D map, orthomosaic, point cloud, and contour lines were delivered to the client.
work. Twelve months later the bridge was completed.
Results: Bridge and Containment
With this information a group of geologist were able to analyze the mountain with a high-level of detail and identified that there was a geological fault that ran through the surrounding terrain, which meant the whole area would continue to be at high-risk, regardless of retention solutions. With this key insight, the team decided that a bridge across the dangerous area was required. Undoubtedly, the decision dramatically reduced future expenditures and risks for travelers. Using the same Fly North analysis, the team designed and quoted the bridge and necessary containment work. Twelve months later the bridge was completed.
