Boston Harbor Improvement Dredging

The U.S. Army Corps of Engineers, New England District will be issuing an Invitation for Bids for Improvement Dredging of the Broad Sound North Entrance Channel, portions of the Main Ship Channel, President Roads Anchorage and Portions of the Reserve Channel of Boston Harbor, Boston, Massachusetts Federal Navigation Project. This will be an unrestricted competitive solicitation requiring mechanical dredges to perform the work. The NAICS code for this procurement is 237990. The estimated construction cost is between $100,000,000 to $250,000,000. Any responsible source meeting this standard may submit a bid to be considered by the New England District. This project consists of dredging approximately 11,700,000 cubic yards (cy) of silt, blue clay, till and weathered rock to improve the following components of the Federal Navigation Project for Boston Harbor: deepening and widening the Broad Sound North Channel to -51 feet Mean Lower, Low Water (MLLW), deepening and widening the Main Ship Channel (MSC) to the Conley Terminal including the turning basin or "MSC Notch" to -47 feet MLLW, deepening the President Roads Anchorage and deepening the lower Reserved Channel to -47 feet MLLW. The improvement depths noted above are required to be an additional two feet deep in areas of hard material like till and weathered rock. The material dredged to create the federal navigation project improvements will be placed at the Massachusetts Bay Disposal Site (MBDS) approximately 20 miles offshore of Boston Harbor with the exception of a small fraction of the material being placed as a cap to the Main Ship Channel Confined Aquatic Disposal cell that will be completed in December 2017, just downstream of the inner confluence of the Chelsea and Mystic Rivers. Fast rock is defined as rock having a compressional wave velocity greater than 2,700m/s and will not be removed as part of this contract as no blasting will be permitted. The contractor will be required to bring equipment to accomplish all dredging by mechanical means for the material types previously noted with strength characteristics less than fast rock. Dredging operations will be permitted 24 hours per day and 7 days per week and are expected to take up to 3 years to complete. There are no "no dredge" windows during this project. The Government anticipates including definitive responsibility criteria in the solicitation. After bid opening, but prior to award, the apparent low bidder will be required to furnish documentation that the prime contractor or subcontractor responsible for dredging has: - within the last 10 years, dredged by mechanical means a minimum of 350,000 cubic yards in a consecutive 30-day period and - within the last 10 years, dredged hard material to depths of 35' or more using mechanical equipment and - equipment to be used on this project is capable of dredging material- up to but not including the strength of fast rock, noted above- to a depth of 50' or greater. This is not an invitation for bids at this time.
