The Herbert Hoover Dike (HHD) rehabilitation project is designed to stabilize and secure the aging dike from potentially damaging severe weather events, and protect the numerous residents and businesses on the southeastern rim of Lake Okeechobee. In 2007, the U.S. Army Corps of Engineers (USACE) placed the HHD on the Top 6 list of dams in the nation needing repair. The USACE Jacksonville District prioritized rehabilitation of dike segments that were identified as most vulnerable, focusing initial efforts to achieve the most significant impacts. In May 2008 the Jacksonville District selected Bauer Foundation Corp. (BFC) to construct a 3-mile long segment of the planned cutoff wall that runs vertically from the dike crest to a depth of 70 feet in certain locations.
The challenge of compiling and viewing the large quantity and diversity of data collected for this project required an innovative solution. In December 2008 BFC selected Geosyntec to develop an application by which BFC and its client, USACE, could view the data as it is collected and interactively search for values and generate time-critical reports.
Geosyntec's Scope of Services
To address this challenge, Geosyntec developed "WallTracker", a database and Geographical Information Systems (GIS) Application based on a Visual Basic, Microsoft Access and ESRI ArcGIS platform. WallTracker allows HHD data to be viewed in plan and cross-sectional views. Data accessible in the application include: construction quality assurance metrics, pre-drill and panel dimensions, slurry composition data, and down hole imagery. Users can navigate around these views, select data to be visualized, and access data at a given location through an intuitive user interface. Laboratory reports can also be accessed directly from the laboratory's website by selecting location of interest on the WallTracker user interface. The data visualized and accessed is updated (securely and remotely, via the internet) as new data are collected and entered into the system.
Geosyntec's WallTracker application streamlined the workflow that allows data to be compiled as it is collected, verified, and then accessed in an intuitive interface, thereby allowing project managers and stakeholders to track the details, conduct prompt analyses of trends, and evaluate the progress of this very involved and time-critical construction project.
