The New Haven Harbor Improvement Dredging contract will include deepening the main channel, maneuvering area, and turning basin from -35 to -40 feet, MLLW, widening the existing channel by 100 feet (from 500 feet to 600 feet in the entrance outside the breakwaters and from 400 feet to 500 feet inside the harbor), lengthening the turning basin, and widening the channel bend near the East Breakwater from 560 feet to 800 feet.  These improvements will require dredging about 4.6 million cubic yards (cy) of ordinary improvement material and removing up to 60,000 cy of rock for a total of 4.66 million cy (Volume includes +2 feet of allowable overdepth in areas of regular material and +4 feet of allowable overdepth in areas of rock). Total dredge volumes presented above are subject to change after the 2025 – 2026 maintenance dredging work is completed. The material proposed to be dredged from the harbor is composed of mainly sandy silt and clays with some fine sand in the entrance channel.  The material has been determined to be suitable for unconfined open water placement at the Central Long Island Sound Disposal Site and for beneficial use in a limited capacity at four local sites within the harbor.  The Quinnipiac, Mill, and West Rivers are not part of the improvement effort.

The event will be a virtual project overview presentation followed by meeting time slots to discuss project specifics one-on-one with the New England Team.  The event will take place on June 30, 2025, from 10:00 am to 12:00 pm. Individual meetings will be offered to construction contractors every 30 minutes from 12:30 pm to 3:00 pm that same day. These meetings will be offered on a “first come, first served” basis.  The purpose and focus of the event will be to seek marine construction industry input and answer questions regarding best practices for the technical execution of the improvement project.  A list of questions for bidders to consider and available project information will be provided at least one week ahead of June 30, 2025.  Additional information is available on the New Haven Harbor Industry Day website at https://www.nae.usace.army.mil/Business-With-Us/Contracting/New-Haven-Harbor-Improvement-Project-Industry-Day/
