Project Specifics

The new 110′ x 600′ Chickamauga Lock is being designed and constructed by the Nashville District, U.S. Army Corps of Engineers (USACE). The Judy Company (JC) has been contracted to construct a barrier wall consisting of an angled grout curtain. The challenge of compiling and viewing the large quantity and diversity of data collected for this project requires an innovative solution. In May 2010, Judy Company selected Geosyntec to develop and implement a method by which JC and its client, USACE, could view the data as it is collected and interactively search for values and efficiently generate time-critical reports.

Geosyntec Scope of Services

To address this challenge, Geosyntec developed “GroutTracker”, a database and Geographical Information Systems (GIS) Application based on a platform using Visual Basic, Microsoft Access, and ESRI ArcGIS. GroutTracker allows Chickamauga Lock design and grouting data to be viewed in plan and cross-sectional views. Data accessible in real time in the application include: drilling, water testing, and grouting results in accurate locations, and boreholes color-coded by the grout take and lugeon value measured directly from on-site instrumentation. Users can navigate around these views, select data to be visualized, and access data at a given location through an intuitive user interface. The system can also generate a series of reports on demand, including a Daily Report for immediate submission to the USACE that tracks pay items; a Materials Usage report that reports the current mass or volume of grouting mix materials delivered to the site, mixed in the batch plant, injected, backfilled or wasted; and an Analysis Report that provides detailed statistics for selected holes or regions.

Notable Accomplishments

Geosyntec’s GroutTracker streamlined the workflow that allows data to be compiled in an efficient and quality-controlled fashion and viewed in an intuitive interface, thereby allowing project managers and stakeholders are able to track the details, conduct prompt analyses of trends, and evaluate the progress of this very involved and time-critical construction.
