About this file
This federal solicitation seeks maintenance dredging services for portions of the Newark Bay Federal Navigation Project in New Jersey. The U.S. Army Corps of Engineers proposes to remove approximately 600,000 cubic yards of sediment from the Main and Port Newark Channels to depths of -40 feet and -50 feet MLLW plus one foot allowable overdepth using a mechanical dredge with a closed clamshell environmental bucket. A contractor will be required to transport, dewater, process and place the dredged material at a state-permitted upland site. The contractor must provide all necessary placement permits within 35 days of notification of being the apparent low bidder. Work is estimated to cost between $25-100 million and must commence within 5 days of notice to proceed, maintaining a daily production rate of at least 2,500 cubic yards to minimize channel closure time between August 2022 and March 2023.
