Great Lakes Dredge Secures Tampa Harbor Dredging Contract

Great Lakes Dredge & Dock Co. has just won a $47.9 million contract for channel dredging works in Hillsborough County, Florida.

According to the FedBizOpps, the project consists of dredging approximately 4 million cubic yards from the Big Bend Channel of Tampa Harbor. Also included in the project is the Entrance Channel, Turning Basin, East Channel, Inner Channel, and associated wideners.

The main aim of the project is to deepen the existing channel segments from approximately 36 feet to 41 feet plus 2 feet of advance maintenance and associated overdepths.

The Entrance Channel will be widened from 200 feet to 250 feet for a length of approximately 1.9 miles. Additionally, the existing Turning Basin will be expanded to provide a minimum diameter of 1200 feet and turn wideners added where necessary.

All dredged material from the project will be disposed of in Dredge Material Placement Facility DMPF 3-D located approximately 2.5 nautical miles from the area to be dredged.

It is anticipated that the material to be dredged from the East Channel and associated berthing areas includes rock of sufficient hardness and massiveness such that blasting or some other form of pretreatment would be needed to efficiently remove the rock in conjunction with dredging of this reach.

The U.S. Army Corps of Engineers, Jacksonville District, estimates that the whole project will be completed no later than January 31, 2020.
