South Coast Engineers Preannounce Upcoming Dauphin Island, AL. Dredge Bid

Posted on July 26, 2023

Notification of Upcoming Project

Notice is given to prospective Bidders that the Town of Dauphin Island intends to advertise for bids by qualified Contractors to construct the “Town of Dauphin Island East End Beach and Dune Restoration Project.” The following information is provided for consideration and general planning by prospective Bidders; however, the Town reserves the right to change quantities and project features as may be necessary to address site conditions at the time of advertising.

The successful Bidder will provide the dredge and support vessels, labor, equipment, supplies and all other materials and submittals to perform all operations for (1) excavating, transporting, placing dressing and grade sand fill from an offshore borrow area; (2) providing and planting new native beach and dune vegetation; (3) providing and installing new beach sand fencing; and (4) providing necessary environmental compliance testing as required by pending regulatory approvals for the project.

The presently estimated quantity of offshore sand to be excavated and placed is 1,135,000 cubic yards. The fill site extends for approximately 8,400 feet west of Ft. Gaines, on the eastern end of Dauphin Island, Alabama. A suitable borrow source has been identified at a site approximately 4.5 miles south of the fill site. Water depths at this borrow site range from approximately 16 to 22 feet, with the average depth being about 18.5 feet. The thickness of cut proposed is 13 to 18 feet. Construction is expected to be performed by use of a hydraulic pipeline dredge. Prospective Bidders are alerted to the existing shallow water depths surrounding the fill site and to the presence of newly restored subaerial island features between the borrow and fill sites along the path of the pipeline corridor. A mechanical (clamshell) dredge will not be allowed.

Applications for State and Federal regulatory approvals have been submitted to the agencies and permits are expected to be issued in mid-summer of 2023 with construction to follow during the late summer and autumn of 2023.

In order to ensure that all prospective Bidders are treated equitably, any questions and/or requests for further information shall be submitted in writing or e-mail to: Beau Buhring, South Coast Engineers or Written responses to questions will be published in the same manner as this Notice was distributed.

DredgeWire has been advised that it is expected that the formal bid announcement will be made in late August 2023.
