1.3.1 Project Description

The work to be performed under this project consists of providing all materials, plant, labor, equipment and services (except those furnished by the Government) to perform maintenance dredging of Arthur Kill 35' Reach, New York and New Jersey Channels, Federal Navigation Project, with placement of the material at a Contractor furnished, state-permitted, Upland Placement Site(s). The Contractor will be solely responsible for coordinating, obtaining, and be in compliance with all requirements for transportation, offloading, dewatering, processing, and disposing of the dredge material, as well as for obtaining all permits and for meeting all requirements for the processing and disposal site(s) identified by the Contractor. See Section 35 20 29 DREDGED MATERIAL TRANSPORT AND PLACEMENT MONITORING for more information.

The maintenance for this project consists of dredging a total of approximately 155,035 CY of material based on the plans and specifications survey performed in December 2025. For more details, see ESTIMATED QUANTITIES in Section 01 30 00 ADMINISTRATIVE REQUIREMENTS of these Specifications. The dredge material has been determined to be composed of primarily silt and clay.

A summary of the Dredging Areas is shown in the table below:

Contract time for completion is based on a minimum average production rate of 2,500 cubic yards (CY) per day for dredging, transportation, processing and placement at a contractor furnished, state permitted, Government approved upland placement site(s). Should the total quantity of material exceed the estimated quantities within the Solicitation Contract Form, additional time will be allowed at the rate of one (1) calendar day for each 2,500 cubic yards in excess of the established limit. The time stated for completion shall include final clean up.

The contractor must bid on all items of the bid schedule. The following CLINs require dredging of the Arthur Kill 50' Reach, New York and New Jersey Harbor, Federal Navigation Project, with subsequent transportation, processing and placement of the dredged material at a contractor furnished, state permitted, Government approved upland placement site(s):
