The U.S. Army Corps of Engineers, New England District, is seeking information from small and large businesses for a dredging project in Providence, Rhode Island, under NAICS code 237990. The project is estimated to cost between $80,000,000 and $100,000,000, with a solicitation expected around March 15, 2027. Construction is scheduled to begin in September 2027 and last approximately two years, spanning two dredging seasons from September 1, 2027, to August 31, 2029. The work is divided into two primary sequences: the construction of a new Confined Aquatic Disposal (CAD) cell at Edgewood Shoals North, including an access channel, and the subsequent maintenance dredging of the Providence River and Harbor Federal Navigation Project to a depth of -40 feet MLLW plus two feet of allowable overdepth. The total scope involves mechanically dredging approximately 5,500,000 cubic yards of material using closed clamshell buckets. Specifically, 3,200,000 cubic yards will be removed to create the CAD cell, with material placed at Port Edgewood Basin, Fox Point Reach CAD cells, Prudence Island, and the Rhode Island Sound Disposal Site. The remaining 2,300,000 cubic yards of maintenance material will be placed within the newly constructed Edgewood Shoals North CAD cell. To meet strict environmental windows and project timelines, the contractor must maintain a production rate of at least 300,000 cubic yards every 30 calendar days, operating 24 hours a day, 7 days a week. Interested firms must submit a capabilities package by November 26, 2026, demonstrating experience with these production rates and open water placement in New England during winter months.

AI Contract Overview

The Kiefer Landfill, operational since 1967, actively manages landfill gas through a network of approximately 350 extraction wells, with system performance dynamically adjusted based on daily waste placement. To comply with evolving environmental regulations and accommodate ongoing landfill expansion, a structured program is in place to replace underperforming wells and install new ones quarterly, with an average of eight new wells installed and ten decommissioned each quarter. This cyclical approach ensures continuous regulatory compliance and optimal gas capture efficiency while supporting the landfill’s long-term operational integrity. The initiative is designed for rapid, predictable field execution to maintain consistent gas management capabilities. A solicitation titled Quarterly LFG Well Installation Services, 2026, with reference number 4699, was issued on June 18, 2026, and is open for responses until July 23, 2026, by the California Waste Management and Recycling agency headquartered in Sacramento. The project requires contractors to execute well installation and decommissioning activities on a strict quarterly schedule to meet environmental mandates. Primary point of contact is John Jowers, Associate Engineer, with Crystal Sheehan, Senior Contract Services Officer, also available for inquiries. The work must be performed in California, with all services aligned to the operational timelines and technical requirements of the Kiefer Landfill.
