Case Study: Connecticut State Pier Infrastructure Improvements
Client
Kiewit Infrastructure Co. (Construction Manager-at-Risk)
Industry
Marine Construction, Renewable Energy Infrastructure
Location
New London, Connecticut
Project Overview
The Connecticut State Pier Infrastructure Improvements Project (CTSP) is a landmark redevelopment designed to transform the New London Pier into the first operational U.S. heavy-lift marine terminal. This facility will serve as a hub for offshore wind towers, nacelles, blades, and other maritime cargo — supporting the nation’s push toward 100% clean electricity by 2035.
As the construction manager-at-risk, Kiewit rebuilt the site into a heavy-lift-capable terminal with enhanced utility systems, remediated contaminated areas, and expanded capacity to handle larger and more complex cargo.
Objective
Control onsite sediment disturbed during completion of redevelopment activities at the pier terminal, ensuring compliance with strict federal and state environmental standards while construction progressed.
GEI Works Solution
GEI Works designed and manufactured a Type 3 HD Impermeable Turbidity Curtain, tailored for the site’s deep-water and high-energy marine conditions.
Key Features:
-
Depth: Custom curtain panels ranging from 25–50 feet
-
Durability: Heavy-duty design to withstand tides, currents, and vessel activity
-
Phased Delivery: Materials shipped to match Kiewit’s multi-stage construction timeline
-
Performance: Contained sediment effectively, preventing dispersion into the Thames River
Project Highlights
-
Environmental Protection
The turbidity curtain successfully controlled onsite sediment in the water, ensuring compliance during critical construction activities. -
First-of-its-Kind Marine Terminal
The completed project now accommodates offshore wind towers, nacelles, blades, and diverse maritime cargoes, supporting clean energy expansion. -
Long-Term Project Support
With a duration of over 1 year, GEI Works delivered all goods on time throughout the project, aligning with Kiewit’s operational needs.
Outcome
The Connecticut State Pier now stands as a state-of-the-art heavy-lift marine terminal — ready to support the assembly and delivery of approximately 160 offshore wind turbines, providing renewable energy for over 1 million homes. GEI Works’ Type 3 HD Turbidity Curtain played a vital role in protecting waterways during construction, reinforcing our reputation as a trusted partner for large-scale marine infrastructure projects.
