Fy21 Savannah Inner Harbor Maintenance Dredging

FY21 Savannah Inner Harbor Maintenance Dredging: work is located in the deep draft Savannah Harbor navigation project in Georgia. The Savannah Harbor project is located on the border of Georgia and South Carolina (SC) in Chatham County. The Savannah Inner Harbor channel’s existing project depth is -42.0 ft. MLLW and 500 ft. wide to the upper end of Kings Island Turning Basin: -36.0 ft. MLLW and 400 ft. wide to the upper end of Argyle Island Turning Basin; and -30.0 ft. MLLW and 200 ft. wide to the upper limit of the project. Refer to Table 1 for the Savannah Inner Harbor stationing and depths which include current depths and post-SHEP depths. The Savannah Inner Harbor channel is undergoing a deepening project (SHEP) from stations 0+000 to 103+000 and Kings Island Turning Basin. The project also includes the construction of channel wideners which will also be required dredging for this project. The deepening is scheduled to be completed in December 2021. Savannah Harbor’s Kings Island Turning Basin (KITB) is the primary turning basin for large civilian and military ships, lying adjacent to the Georgia Ports Authority docks. KITB requires dredging twice a year to allow the loaded ships to freely turn when using the port. Approximately 1.6 million cubic yards of maintenance material is removed from the KITB annually. Current project and advance maintenance depths authorized for Savannah Inner Harbor are below. The Inner Harbor is expected to undergo a deepening which will alter the project depth by -5 ft. MLLW. Deepening of portions of the Savannah Inner Harbor may be completed during this contract and required maintenance dredging depth may be adjusted accordingly. Other contractor(s) may be working for the Savannah District on the Savannah Harbor, to include confined upland dredged material containment areas and designated staging areas.
