The U.S. Army Corps of Engineers is planning a maintenance dredging project along the Chesapeake and Delaware Canal and Upper Chesapeake Bay. The estimated project magnitude is between $10 million and $25 million. Performance of services will occur at various locations along the Inland Waterway in that region. The base work period of performance is 120 calendar days from the notice to proceed, but all dredging is restricted annually from April 1 to September 30 to protect migratory fish. This is a pre-solicitation notice for planning purposes only, and the government will not accept proposals based on this notice.
