Geotechnical Monitoring for the Replacement of the Chickamauga Lock
The Chickamauga Lock is a navigation lock on the Tennessee River, seven miles upstream of Chattanooga. Because the existing 80-year-old 60-foot-by-360-foot lock was no longer suitable for the larger barges now used by the transportation industry, the decision was made to replace the lock with a new 110-foot-by-600-foot lock. The new lock makes barge transport more efficient and solves structural issues caused by the existing concrete aggregate. As part of this project, Geosyntec provided geotechnical monitoring during the replacement, maintaining and operating an automated instrumentation and data-management system. This system was used to enhance worker safety while the lock was being installed to monitor the existing lock during construction and to verify structural performance consistent with design expectations.
