Description

This is a Sources Sought/Request for Information Only.  This is not a Solicitation Annoucement, nor is it a Request for Proposal..  This does not obligate the Government in any contract award.  The U.S. Army Corps of Engineers, Savannah District is issuing the sources sought synopsis as a means of conducting market research to identify parties having an interest in and the resources to support the requirements as stated in the scope of work.  The results of this market research will contribute to determining the method of procurement.  The applicable North American Industry Classification System (NAICS) code assigned to this procurement is 237990 - Dredging and Surface Clean Up Activities) with a size standard of $37,000,000.00.  The Product Service Code is Z1KF - Maintenance of Dredging Facilities.  

Savannah Harbor is located at Savannah on the northern coast of Georgia / southern coast of South Carolina in Chatham and Jasper Counties, respectively. The Savannah River is the line of demarcation separating Georgia from South Carolina. Savannah Harbor Dredge Material Containment Area (DMCA) 13A, located along and to the north of the Savannah River North Channel across from Elba Island, lies in Jasper County, South Carolina. The area is one of nine confined dredge material containment areas used for dredging the Savannah River channel. The containment area is roughly 1,380 acres in size and parallels the Savannah River beginning at approximate channel station 48+000 and extending south-west to channel station 58+000 and then along the Back River Channel from station 0+000 to about station 6+500.DMCA 13A is located between DMCA 12A and DMCA 13B. Dikes have been constructed around the entire perimeter of this area for confined storage of dredging materials. Although the area has not always had dikes, it has received dredged materials from the Savannah River throughout the 1900’s. The disposal area is drained using a series of water control structures (weirs). The six weirs are located along the backside of DMCA 13A and empty into the marsh.  Two of the six weirs are blanked off. The dikes are periodically raised as needed to increase capacity for dredge spoils.

Savannah Harbor DMCA 13A will be used primarily for disposal of the O&M maintenance dredging materials that will be excavated during dredging of the Savannah River. In order to safely contain these materials, the capacity of DMCA 13A needs to be increased and improvements to the water control outlets need to be made. The Scope of Work for this project consists of raising the DMCA 13A perimeter back dike, repairs and modifications to four of the six existing weir/water control structures across the back (marsh-side) dike, and the expansion of the bird island.

The existing back dike currently spans a length of approximately 10,600 feet and has a crest elevation of approximately 46 feet MLLW. After extending the interior counterweight, the back dike will be raised to a uniform crest elevation of 52 feet MLLW to gain additional capacity for containment of Savannah Harbor dredged material. The existing 13A/13B cross dike currently spans a length of approximately 2,500 feet and has a crest elevation ranging from about 46 to 51 feet MLLW. After extending the interior counterweight for the span, the cross dike will be raised to a crest elevation that varies from 52 feet MLLW in the back to an elevation of 57 feet MLLW at the front. The existing 13A/12A cross dike currently spans a length of approximately 4,800 feet and has a crest elevation ranging from about 52 to 55 feet MLLW. The cross dike will be raised to a crest elevation that varies from 52 feet MLLW in the back to an elevation of 57 feet MLLW at the front. The existing front dike currently spans a length of approximately 16,200 feet and has a crest elevation ranging from about 51 to 52 feet MLLW. The front dike will be raised to a uniform crest elevation of 57 feet MLLW. The fill material for raising the dikes will be obtained from the interior of DMCA 13A. Repairs and modifications to the existing weirs will involve temporary removal, replacement of corroded steel, reinforcement of the outfall stub, the addition of a new bonneted knife gate valves, a new larger weir platform, a catwalk extension, and re-installation on a new slab foundation.  The Period of Performance is 540 days from Notice to Proceed.
