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.
Unless properly recognized, the data management requirements can contribute to the complexity, duration and budget of the project. This paper 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. This technology was used to provide information to the U.S. Army Corps of Engineers (USACE) as part of the high-profile rehabilitation of the 232-kilometer long Herbert Hoover Dike (HHD) around Lake Okeechobee in South Florida. The implication of this technology to other earthwork projects is demonstrated.
