Maintenance Dredging of East River, South Brother Island Channel, New York, Federal Navigation Project

The New York District of the U.S. Army Corps of Engineers (USACE) proposes to perform maintenance dredging of East River, South Brother Island Channel, New York, Federal Navigation Project to a depth of -35 feet Mean Lower Low Water (MLLW) plus 2 feet of allowable over-depth. The proposed maintenance dredging would remove approximately 425,000 cubic yards (CY) of critical shoals from the East River South Brother Island Channel with subsequent placement at the Historic Area Remediation Site (HARS). The dredged material from South Brother Island Channel is expected to consist of 0% gravel, 13.9% sand, 63.9% silt, and 22.2% clay. Due to restrictions in the New York State Department of Environmental Conservation Water Quality Certificate, the proposed work can only be performed utilizing a mechanical dredge with a closed clamshell environmental bucket. Additionally, multiple scows and tugboats will be needed to perform the work during the dredging, and placement operations. The dredged material would be required to meet all federal, state, and local criteria required by the government agencies having jurisdiction where the dredging and placement sites are located. Once the contract is awarded, the contractor will be required to commence work within five (5) calendar days after the date of receipt of the notice to proceed and maintain an integrated production rate of at least 8,000 cubic yards per calendar day for the dredging and placement of material. The presence of dredging equipment in the channel will impact vessel traffic and it is necessary to maintain this production rate while minimizing the duration of this impact. The proposed work is anticipated to take place in the fall/winter of 2023. The work is estimated to cost between than $5,000,000 and $10,000,000.00. This is an unrestricted procurement.
