The U.S. Army Corps of Engineers, Savannah District, is conducting preliminary research to determine the market capabilities of potential contractors to perform maintenance dredging in the Savannah, GA and Brunswick, GA Inner Harbors.
The dredge must have the capability to dredged to a depth of -62′ MLLW and pump the material a total distance of approximately 50,000 linear feet and then up an approximate 40 ft relative to (MLLW) dike embankment with another 4,000 linear feet to the disposal area head section location.
A segment of harbor dredging will include pumping hard packed sand approximately 30,000 linear feet and then up an approximate 30 ft relative to (MLLW) dike embankment.
Sufficient pipe must be available for the required pumping distance and booster pumps will be allowed. QCS will be required.
An equipment list and capability of each piece of equipment to be used in the work is required. Equipment specified must be capable of performing the work required. Examples of capability include depth to which the dredge can reach and length of pipeline to which a dredge can pump.
Dredging will take place in harbors with diurnal tidal cycles. Maximum tides in non-storm conditions may reach 12 ft. Average flows to be expected are about 1.5 to 3 ft./sec. with maximum flows of about 4 ft./sec.
