Inner Harbor Dredging Reaches C, D, & E Stations 0+000 to 70+000 (№17459899)

Project Location: Savannah Harbor is located at Savannah, Chatham County on the northern coast of Georgia and the southern coast of Jasper County, South Carolina. The Savannah River North Toe, down river of the confluence of the Sediment Basin is the boundary line separating Georgia from South Carolina. The existing Savannah Harbor inner harbor channel extends from Station 0+000 at the landward end of the navigation jetties inland to Station 112+500 in Port Wentworth, Georgia. The deepening project does not extend the entire length of the channel. The deepening for this project begins at Station 0+000 and ends at Station 70+000.

This solicitation is an Invitation For Bid (IFB). The U.S. Army Corps of Engineers, Savannah District intends to award a contract on the basis of this notice.

The existing navigation channel has an authorized depth of -42 feet, epoch 1983-2001 Mean Lower Low Water (MLLW) for the entire length of the inner harbor channel. The deepening of the channel will include dredging an additional -5.0 feet of unclassified material below the existing project depth, advance maintenance of the channel (ranging from -2.0 feet to -6.0 feet) and an allowable pay overdepth of -2.0 feet. Material will be removed to a maximum pay slope plane of 1 vertical on 3 horizontal. The existing channel width will be reduced in most areas by up to 30 feet to allow for dredging on the existing side slope.

Project Description: The project includes removal of all material, including any material within the existing maintenance prism, to required project depths. Dredging of maintenance and unclassified material between Stations 0+000 to 70+000, debris removal, diving, and bird abatement shall be included in the contract. All dredged material will be disposed of in existing confined upland disposal areas. Hopper dredging is not allowed for this work. Work will not be allowed above Station 63+360 in the harbor from approximately April 1 to May 15 to avoid impacts to striped bass fishery resources. Dredging of stations 55+000 to 70+000, excluding maintenance material from 57+000 to 60+000, will not begin before 1 December 2020.

The material to be removed includes new work materials and overlying maintenance materials. O&M quantities are subject to change with O&M cycles, but approximately 9919000 cubic yards of maintenance material will be removed along with new work material. Materials may vary substantially both vertically and horizontally. Two feet of paid overdepth will be allowed, however the contractor shall not exceed -3.0 feet beyond the maximum pay depth.

Disposal of all materials from the inner harbor will be in the existing confined upland Dredge Material Containment Areas (DMCA) designated as 13A, 13B, 14A, 14B, and Jones/Oysterbed Island. The contractor will be responsible for proper operation and maintenance of the disposal areas during dredging operations. Material between Stations 24+000 and 55+000 contains material with elevated levels of naturally occurring cadmium that will be dredged as part of this project. All cadmium materials will be placed within disposal area 14A, and DMCA 14B will serve as a backup. Dredging of the cadmium materials will be required prior to placement of a 3 +/- 1ft foot cap of non-cadmium material over the entire site. To facilitate placement of the cap, the cadmium material will be distributed evenly over the entire disposal area(s). The material designated for the cap is of relatively coarse grained material from between Stations 0+000 and 24+000. Prior to placement of the cap, the cadmium will be kept in a moist state.

Wildlife/Bird abatement will be performed in the disposal areas that are receiving the cadmium materials to reduce the wildlife use of those areas both during the construction period and before capping. This will minimize their risk of potential exposure to cadmium. Acceptable methods for wildlife/bird abatement are described within the specifications.

During previous dredging operations in this area, unexploded ordinance (UXO) has been encountered. In the event that UXO are encountered, follow the procedure as outlined within the specifications. A mechanical dredge shall be required to dredge the maintenance material between the reach of the channel between approximate stations 57+000 and 60+000. The contractor shall screen the material for UXO prior to placement of the material in the confined upland disposal areas.

The contractor will not be entitled to equitable adjustment or reimbursement for work stoppage of 24 hours or less from the time the Contracting Officer directs the contractor to stop for the reasons listed within the plans and specifications.

The estimated construction duration for inner harbor dredging Reaches C, D, & E is 810 days.
