Large scale geotechnical earthworks projects, specifically those related to earth dams, dikes, and levees, often require construction of deep vertical seepage barriers. With increasing frequency, the demands of contract compliance, resource scheduling, quality control, and budget management require structured and efficient management of large data sets.
This presentation discusses an application of Geographic Information Systems (GIS) technology to capture information from multiple data streams and provide geotechnical feedback, quality control, and project control feedback. These data streams are combined in a GIS to be assessed in a common context, and to be analyzed comprehensively. This technology was used to provide information to the U.S. Army Corps of Engineers (USACE) as part of the high-profile rehabilitations of the Herbert Hoover Dike (HHD) in Florida, Wolf Creek Dam in Kentucky, and Center Hill Dam in Tennessee.
