FY20 Savannah Inner Harbor Maintenance Dredging

See Amendment 0002 for Virtual Bid Opening instructions and information.

See Amendment 0001 drawings and specifications.

The Savannah Inner Harbor Contract provides construction services, including furnishing personnel, transportation, mobilization and demobilization, equipment and materials required in connection with maintenance dredging.  This contract is traditionally performed with a hydraulic cutterhead dredge and the duration is expected to be one year from Notice to Proceed.  Up to six million cubic yards of maintenance material is expected to be removed from the inner harbor.

The work is located in the deep draft Savannah Harbor navigation project in Georgia.  The Savannah Harbor project is located in Savannah, Georgia (GA) on the border of Georgia and South Carolina (SC) in Chatham County.  The Savannah Inner Harbor channel is 42 ft. deep MLLW and 500 ft. wide to the upper end of Kings Island Turning Basin: 36 ft. deep MLLW and 400 ft. wide to the upper end of Argyle Island Turning Basin; and 30 ft. deep 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.

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.  If such work occurs, the contractors shall coordinate activities under the direction of the Contracting Officer.

All material dredged from the Savannah Inner Harbor shall be placed in upland confined disposal areas adjacent to the Savannah River, with DMCA-13A receiving the majority of the maintenance material. Savannah confined upland disposal areas DMCAs 12A, 13A, 13B and Jones Oysterbed Island are owned by local sponsor Georgia Department of Transportation.  Disposal areas DMCAs 14A and 14B are owned by the Joint Project Office of the Georgia and South Carolina Port Authorities and portions of DMCAs 2A and Jones/Oysterbed are owned by the Georgia Department of Transportation and the US Fish and Wildlife Service, and DMCA 1N is owned entirely by the US Fish and Wildlife Service.  The Federal Government holds existing easements on all confined upland disposal areas in the Savannah Harbor except DMCA 1N which has a Memorandum of Understanding.

Environmental windows limit the timing of dredging in the Savannah Inner Harbor.  The environmental windows in Savannah include a Striped Bass spawning window (2 weeks within the window of 1 April through 15 May) which limits the amount and timing of dredging above station 63+250 (River Mile 12), and a dissolved oxygen window (approximately July 1 through September 30).  An environmental window also exists for sturgeon between 1 May and 30 October annually, no dredging is allowed above station 105+500, cutterhead dredging below 105+500 during those months will monitored for sturgeon take.
