The tight channel was challenging, especially with large dredging materials and vessels. Southwind used hydraulic dredging to pump the materials out of the shallow lagoons through a pipeline to a disposal facility, known as Site 83, off Roosevelt Boulevard.
Southwind has a $2.1 million contract, but about 61 percent of that will be covered by state grants, because that proportion of the project area covers waters under state jurisdiction, Bergen said.
This project, awarded to Marine Diving Solutions by the USACE Jacksonville District. Project consisted of the opening of the sluice gate, removal and replacement of the existing stem, approximately 80 feet in length, connected to the gate; stem guides to be installed on the structure to support it; and a rising-stem pedestal operator, which includes a portable electric operator, to be installed in the top of the intake tower. Contractors are required to work in the wet as the gate will be removed and replaced in the wet.
TITAN provided SSHO and Quality Control for the project as well as Preconstruction Plans
