04 - W912DS-22-B-0012 Flushing Bay and Creek NY - Plans.pdf

This document outlines a federal contract opportunity for maintenance dredging of Flushing Bay and Creek in New York. The U.S. Army Corps of Engineers, New York District, is soliciting bids to remove approximately 150,000 cubic yards of sediment from Flushing Bay and Creek to a depth of -15 feet MLLW plus 2 feet of allowable over-depth. The dredged material consists primarily of sand, silt, and clay. Work must be performed with a mechanical dredge and closed clamshell environmental bucket due to state permit restrictions. Multiple scows and tugboats will be needed for dredging and transport operations. The dredged material must meet all applicable federal, state, and local criteria for placement in a suitable, state-permitted upland site. Bidders must be able to commence work within five days of notice to proceed and maintain a daily production rate of 2,250 cubic yards for dredging and placement. The estimated cost of the project is between $10-25 million, and work is anticipated to occur between September and November 2022.
