Scope of Work FY22-1 Baltimore Harbor & Channels Maintenance Dredging Maryland Channels, Chesapeake Bay, Maryland Project Description: The project consists of maintenance dredging approximately 1,500,000 cubic yards (cy) from the deep-draft federal navigation channels serving the Port of Baltimore. The work is to be performed between November 2021 through March 2022. The dredging depth is planned for 51 feet mean lower low water (MLLW) with an additional 1 to 2 feet of allowable overdepth for three channel reaches including: Fort McHenry, Craighill Entrance, and Cutoff Angle Channels. The channels vary in width from 700 to 1,740 feet. The material dredged from the Fort McHenry Channel (approx. 525,000 cy) will be placed in the Masonville Dredged Material Containment Facility. The material dredged from the Craighill Entrance and Cutoff Angle channels (totaling approx. 945,000 cy) will be placed at the Paul S. Sarbanes Ecosystems Restoration Project at Poplar Island. The work will include an optional item for dragging of an approximate 2,000,000 square foot area of the Northwest Branch East Channel, which is authorized to a depth of 49 feet MLLW. A large portion of the work may be performed during the winter months when weather conditions are most severe and will be accomplished in a heavy commercial waterway supporting the Port of Baltimore. The equipment required for this work commonly consists of two 30 plus cubic yard clamshell dredges, one 24-30 inch hydraulic unloader, six to eight large tugs, six to eight 2,500 6,000 cubic yard material scows, a drag bar and barge, and appropriate attendant plant and pipeline. The material will be dredged by clamshell/bucket and scow and placed within an anticipated period of performance of 130 calendar days from receipt of Notice-to-Proceed. 10 additional calendar days will be allowed if optional item 0008 is exercised and no additional construction time will be allowed if optional item 0009 is exercised.
