Boston Harbor Navigation Improvement Project-Phase 3 Rock Removal

The third phase of the improvement project, this contract, shall remove the remaining material in the Boston Harbor Federal Navigation Project (FNP) to achieve authorized project depth. The project features include: removal of material in the Main Ship Channel (MSC) to the Conley Terminal, including the turning basin or "MSC Notch", to -49 feet MLLW, removal of material in the Reserved Channel to -49 feet MLLW, and removal of material in the President Roads Anchorage to -49 feet MLLW. A CAD file with the -49 foot MLLW Contour Limits will be provided to the Contractor. The Contractor shall be required to remove all material within that limit to -49 feet MLLW. There is an allowable 2-foot overdepth within the -49 foot MLLW Contour Limit. One limited area within the Main Ship Channel shall be brought to a depth of -42 feet MLLW with an allowable 2-foot overdepth. The Government will pay for a 1ft.V:1ft.H side slope. The material to be removed under this contract is material consisting primarily of rock with limited amounts of ordinary and hard material (clays, silts, sands and gravel) remaining as overburden. The Port of Boston is the largest port in New England and one of the principal ports on the east coast of the United States. Each year more than 16 million tons of cargo (2018) pass through this regional economic anchor. Over 130 cruise ships visited the Port of Boston in 2019. Users of the FNP include commercial and private fishermen, law enforcement, lobstermen, commuters, sea planes, recreational boaters, swimmers, and many more. Vessel traffic may impact the work under these specifications and the Contractor shall consider this factor in their bids. The Contractor's effective coordination of blasting and dredging operations with the users of the harbor is essential to the success of this contract. Under this contract the successful offeror will be required to provide the equipment and materials required for the removal of rock from the aforementioned areas and place the rock at the MBDS offshore.
