This document outlines a federal contract opportunity for maintenance dredging of the Long Island Intracoastal Waterway at Moriches Bay in New York. The U.S. Army Corps of Engineers proposes to remove approximately 100,000 cubic yards of sand from the waterway and place it along the shoreline of Cupsogue Beach County Park to maintain authorized project dimensions and ensure safe navigation. Dredging will be required to a depth of negative six feet plus two feet of allowable overdepth using a hydraulic cutterhead dredge and other equipment. The contractor must commence work within five days of receiving the notice to proceed and maintain an integrated production rate of at least 2,200 cubic yards per day to minimize vessel traffic impacts. The contract is estimated to cost between $1,000,000 and $5,000,000 and will be awarded in late July 2022, with work anticipated from October 2022 through January 2023. Liquidated damages of $2,686 per day will be assessed for delays in completing the project.
