Chickamauga Lock and Dam - GroutTracker Developer
« All Projects

Geosyntec developed the GroutTracker system to analyse and visualize grouting data collected during this grout curtain installation.

The new 110' x 600' Chickamauga Lock is being designed and constructed by the Nashville District, United States Army Corps of Engineers (USACE).

The Judy Company 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. Judy Company selected Geosyntec to construct a method by which they and the USACE, can collect, quality-control, and view the data as it is collected.

To address this challenge, Geosyntec developed "GroutTracker", a database and Geographical Information Systems (GIS) Application based on a Visual Basic, Microsoft Access, and ESRI ArcGIS platform. GroutTracker allows Chickamauga design and grouting data to be viewed in plan and cross-sectional views.  Users can navigate through these views, select data to be visualized, and access data at a given location through mouse clicks. In near-real time, users can view the drilling, water testing, and grouting results in accurate locations, and see boreholes color-coded by the grout take and lugeon value measured directly from on-site instrumentation. The system also allows a series of reports to be generated on demand, including a daily report designed 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.

With a streamlined workflow that allows data to be compiled in an efficient and quality-controlled fashion and viewed in an intuitive interface, project managers and stakeholders are able to track the details and progress of this very involved and time-critical construction.
