The U.S. Army Corps of Engineers, Honolulu District recently issued a solicitation entitled, “Kaunakakai Harbor Maintenance Dredging, Molokai, Hawaii and Kahului Harbor Maintenance Dredging, Maui, Hawaii”.
The purpose of the Kaunakakai Harbor Maintenance Dredging project is to conduct maintenance dredging by mechanical clamshell dredge to remove shoaled material within the harbor Federal limits that has accumulated over time.
The maintenance dredging project is needed to restore Kaunakakai Harbor to its authorized depths [-23 ft Mean Lower Low Water (MLLW)] and ensure continued safe vessel navigation.
The major elements of this project include: pre-mobilization activities; mobilization, which includes preparation of temporary construction staging; mechanical clamshell dredging of accumulated sediments estimated at 35,000 cubic yards (CY); transportation and disposal of material to the Kahului Offshore Dredged Material Disposal Site; and demobilization, which includes the restoration of the temporary construction staging area to its original condition. Dredging layer thickness varies, up to 13 feet.
Similarly, the purpose of of the Kahului Harbor Maintenance Dredging project is to conduct maintenance dredging by mechanical clamshell dredge to remove shoaled material within the harbor Federal limits that has accumulated over time.
The maintenance dredging project is needed to restore Kahului Harbor to its authorized depths (-35 ft MLLW) and ensure continued safe vessel navigation.
The major elements of this project include: pre-mobilization activities; mobilization; mechanical clamshell dredging of accumulated sediments estimated at 158,000 CY; transportation and disposal of material to the Kahului Offshore Dredged Material Disposal Site; and demobilization. Dredging layer thickness varies, up to 25 feet.
The estimated period of performance is 18 calendar months for both projects combined.
This project is anticipated to have options; therefore, the total dredged amount may be less than 193,000 CY.
