Site work for a water / sewer project in New York, New York. Completed plans call for site work for a water / sewer project.

Design of Ribbed Mussel Beds in both Bergen and Thurston Basins as required under the approved Jamaica Bay CSO LTCP. This Request for Proposal ("RFx) is being released through Passport, New York City's online procurement portal. Responses to this RFx should be submitted via Passport. CSO-GC-SFS-CM-RH3-CP3 The City of New York ("City") and the United States Environmental Protection Agency ("EPA") entered into an Administrative Settlement Agreement and Order for Remedial Design, Removal Action and Cost Recovery ("Settlement Agreement") for the Gowanus Canal Superfund site, effective June 9, 2016. The City of New York was directed to institute combined sewer overflow (CSO) controls by designing and constructing retention tanks to intercept discharges from outfall RH-034 in the Red Hook (RH) Wastewater Resource Recovery Facility (WRRF) drainage area, and the work to construct this facility is divided into three phases. Further, the Administrative Order for Remedial Action, Removal Action and Design (UAO), (CERCLA 02-2021-2019), effective June 30, 2021, includes construction start and completion milestones for CP-3 of July 1, 2026 and March 31, 2029 respectively. Contracts CSO-GC-SFS-RH3-CP1 ("CP-1") and CSO-GC-SFS-RH3-CP1A ("CP-1A") were the first phase and included abatement of regulated materials; demolition of structures to slab and/or grade, disconnection and/or demolition of utilities; and site preparations for turnover of the project site (CP-1) and construction staging area (CP-1A). CSO-GC-SFS-RH3-CP2 ("CP-2") is the second phase and includes construction of the support of excavation; the excavation, stabilization, and disposal of soils; and construction of the foundation for the facility. This work will be completed approximately 6-9 months after the start of the CP-3 contract. Construction Management services for CP-1, CP-1A, and CP-2 are provided under separate contracts. The third construction package ("CP-3") is for the construction of the CSO facility superstructure, reconstruction/abandonment of impacted conveyance, and construction of public amenities above the below ground portions of the tank. Although the CP-3 UAO construction start milestone date is July 1, 2026, commencement of CP-3 work is dependent on CP-2 construction progress. The scope of CP-3 also includes installation of all CSO Facility components and conveyance including mechanical equipment, electrical conduits and equipment, Heating, Ventilation, and Air Conditioning components, architectural features, and Con Ed network protection structure installation. Contamination may be encountered along the conveyance route, and the appropriate contaminated soil handling operations will be required. Instead of utilizing space on the site, the stabilization activities will likely occur in the street near the excavation. Odor control and groundwater treatment will be considered and included in the contract documents depending on the characteristics of the contaminants identified in the pre design investigation (PDI). Contaminated groundwater may either be treated at the location using smaller mobile treatment system and discharged to the sewer, or it could be trucked to a larger system located at the site for discharge to the sewer or the Gowanus Canal. This work will occur on two properties located at Block 411, Lot 24 and Block 418, Lot 1, bounded by the Gowanus Canal on the west side and Nevins Street on the east side, between Butler Street and Degraw Street in Brooklyn, NY. Additionally, Block 425, Lot 1 will be used by the contractor as the construction staging area. B.
