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 Great Kills Harbor, New York, Federal Navigation Project, with placement of the material at the Historic Area Remediation Site (HARS). 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 entitled "DREDGED MATERIAL TRANSPORT AND PLACEMENT MONITORING" for more information.

The maintenance for this project consists of dredging approximately 190, 885 CY of material based on the plans and specifications survey performed in February 2024. For more details, see "ESTIMATED QUANTITIES" in Section 00 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:

SECTION 01 11 00 Page 2

Contract time for completion is based on a minimum average production rate of 8,000 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 8,000 cubic yards in excess of the established limit.
