Marinex Wins $33 Million Savannah Dredging Contract
Marinex Construction Inc., Charleston, S.C., has been awarded a $33.05 million contract for maintenance dredging in the Savannah Inner Harbor.
The firm-fixed-price contract calls for the removal of as much as 5.6 million cubic yards of maintenance material from the harbor, along with related construction services. The work includes providing personnel, transportation, mobilization and demobilization, equipment and materials needed for the project.
The Corps of Engineers’ Savannah District is the contracting agency. Fiscal year 2026 civil construction funds totaling $33,052,500 were obligated at the time of the award. The contract has a cumulative face value of $37,822,500.
Bids were solicited online, with Marinex submitting the only bid. Work will be performed in Savannah, Ga., with completion estimated for November 30, 2027.
Maintenance dredging is performed throughout the year in Savannah’s inner harbor, traditionally using a hydraulic cutterhead dredge. The Savannah District said as much as 7 million cubic yards of sand, silt and clay can be removed annually from the inner harbor navigation channel. The material is placed in eight principal diked disposal areas located along the north side of the channel.
The inner harbor extends about 21 miles. Savannah District also maintains an 11.5-mile bar channel. Two annual dredging contracts — one for the inner harbor and another for the entrance channel — are used to maintain authorized navigation depths.
The inner harbor project includes the Kings Island Turning Basin, the primary turning basin serving large commercial and military vessels calling at Savannah. The basin requires repeated maintenance dredging because of sediment accumulation.
Marinex has performed numerous maintenance dredging projects in Savannah Harbor in recent years. The company operates hydraulic cutter suction dredges and associated support equipment for navigation, beach nourishment and other marine construction projects along the East and Gulf coasts.
