The Corps also awarded a contract of nearly $23 million to deepen Jacksonville harbor to The Dutra Group of San Rafael, Calif. This is the first of multiple construction contracts that will widen and deepen the existing navigation channel from its current authorized depth of 40 feet to 47 feet.
This contract includes dredging about 3 million cubic yards of material from the entrance channel (Bar Cut-3) to slightly west of the Mayport Ferry (Cut-7). The contractor will transport the excavated material and place it in the Jacksonville Ocean Dredged Material Disposal Site located about six miles southeast of the entrance channel jetties.
In addition to dredging, the work involves turbidity/sedimentation monitoring (pre- and during construction environmental monitoring for direct and indirect effects associated with construction activities), endangered species and marine life observers.
Construction is expected to start in December and the estimated construction duration is roughly two years.
The total cost of the authorized project is $704.5 million; the federal share is $337.8 million and the non-federal share is $366.7 million.
