Maintenance Dredging of Bronx River, NY, Federal Navigation Project W912DS25BA015

Synopsis of the Proposed Dredging - Maintenance Dredging of Bronx River, New York, Federal Navigation Project The New York District of the U.S. Army Corps of Engineers (USACE) proposes to perform maintenance dredging of portions of the Bronx River, New York, Federal Navigation Project. The dredged material would be subsequently transported and placed at the Historic Area Remediation Site (HARS), approximately 4 miles east of Sandy Hook, New Jersey. The proposed maintenance dredging would remove approximately 200,000 cubic yards (CY) of material from the Bronx River channel. Dredging in this channel would be required to a depth of -10 feet Mean Lower Low Water (MLLW) plus 1 foot allowable over depth. The dredged material is expected to consist primarily of silt and clay. The proposed work is anticipated to be performed utilizing a mechanical dredge with a clamshell bucket. Additionally, multiple ocean-going scows and tugboats will be needed to perform the work during the dredging and placement operations. Any debris encountered during dredging operations will need to be appropriately removed and disposed of by the contractor. Based upon the results of testing of the sediments proposed for dredging in the Bronx River, New York, Federal Navigation Project, USACE and USEPA have determined that the material is Category 1, meeting the criteria for ocean placement as described in 40 CFR parts 227.6, 227.27, and 228.15, and is Remediation Material as defined under the USEPA, Region 2/USACE, New York District, guidance. 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 2,500 cubic yards per calendar day for the dredging and placement of the material, accounting for the removal and disposal of expected debris within the dredging footprint. 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 2025. The work is estimated to cost between $5,000,000 and $10,000,000. Liquidated damages of $3,215.00 per calendar day of delay will be assessed to the contractor until all work under the contract is accepted as complete. This is an unrestricted procurement.

The New York District of the U.S. Army Corps of Engineers (USACE) proposes to perform maintenance dredging of the Bronx River, NY Federal Channel. The dredged material would be dredged and subsequently placed at the Historic Area Remediation Site (HARS), approximately four (4) miles east of Sandy Hook, New Jersey. Placement at the HARS requires the contractor to utilize large-capacity ocean-going scows. The proposed maintenance dredging would remove approximately 200,000 cubic yards of dredged material from the Bronx River. Dredging would be required to a depth of -10 feet plus one (1) feet allowable over depth. The dredged material consists primarily of sand and silt. It is anticipated that miscellaneous marine debris will be encountered during dredging operations. This debris will need to be appropriately removed and disposed of at a contractor furnished disposal facility. Once the contract is awarded, the proposed contractor will be required to maintain minimum daily production of 8,000 CY with the use of a mechanical "clamshell" bucket. The anticipated environmental no-work window is from January 01 to September 30. The period of performance will begin once the Notice to Proceed is issued and acknowledged by the Contractor. Failure to complete the work within the period of performance, including contract modifications, will result in the Contractor paying liquidated damages. This is an unrestricted procurement.
