Construction on the Chickamauga Lock Replacement project restarted in September 2015 with the award of the Cofferdam Stabilization contract, which consisted of placing grout along the perimeter of the existing cofferdam cells to reduce the potential for water seepage entering the work area during future lock contracts; this contract was completed in July 2016. The next contract, Lock Excavation, will primarily consist of removing rock and preparing the site for future concrete placements and is scheduled to be awarded in September 2016. The Lock Excavation contract will be a two-year-long contract. The next contract after Lock Excavation will be construction of the new lock chamber. Construction on the Chickamauga Lock Replacement project has been temporarily suspended. The most recent construction activity on the project includes completion of the cofferdam and off-site fabrication of the miter gates, culvert valves, culvert bulkheads and approach wall beams, all completed in 2013. The cofferdam, which can be seen from adjacent roadways as drivers pass by, will be used to provide a "dry" area for construction of the new lock walls and chamber. The miter gates, culvert valves and culvert bulkheads will be stored at Muscle Shoals, Ala., and the approach wall beams will be stored at Watts Bar Dam until needed to complete construction of the lock. The project is not in the president's fiscal year 2015 budget, and will remain in a temporary suspended status until additional funding becomes available to continue construction. Current Chickamauga Lock construction includes completion of the cofferdam, and off-site fabrication of the miter gates, culvert valves, culvert bulkheads and approach wall beams. The cofferdam is substantially complete and the contract will be closed out soon. The cofferdam, which can be seen from adjacent roadways as drivers pass by, will be used to provide a "dry" area for construction of the new lock walls and chamber. The miter gates, culvert valves and culvert bulkheads are substantially complete and that contract will also be closed out soon. These items will be stored at Muscle Shoals until needed to complete construction of the lock. The approach wall beams will be completed in May 2013, and will be stored at Watts Bar until needed to complete construction of the lock. At that time, this contract will also be closed out, finishing the work performed on the new lock using ARRA funds. The project is not in the FY13 Budget, and without additional funding, no further construction will take place. The project will be placed in a mothball status until funding becomes available to continue construction.
