Over the last decade, Cashman Dredging and Marine Contracting Company, LLC has emerged as an industry leader in navigational and maintenance dredging projects. We provide deeper and cleaner waterways through innovative dredging, capping, and processing techniques developed for major East and Gulf Coast / Caribbean customers.
Cashman Dredging has undertaken some of the largest dredging projects in U.S. history. Our crews have moved millions of cubic yards of dredge material, sand, glacial till, clay, and rock, and are experts at processing toxin-impacted or contaminated materials using environmentally safe practices. Providing an array of integrated solutions ranging from environmental and navigational dredging to pond and industrial dredging, Cashman Dredging has earned a reputation for precision and quality. Cashman offers Owners minimal risk to execute their projects safely, on schedule, accurately, and at a predictable cost. Our experience includes working on heavily trafficked waterways, including on riverine and open-water environments. Channels are kept deep and wide enough through dredging for safe movement of ships from deep ocean waters to numerous East/Gulf Coast deep-water harbors.
Utilizing sound engineering and advancing the latest technologies, Cashman executes dredging and restoration projects across a broad range of services. We not only implement the dredging work, we also apply our extensive regulatory experience to help Clients navigate the often complex permit approval processes. Cashman supports the efforts of Clients like the Corps of Engineers at navigation channels and of Port Authorities and the Navy at harbors, and has experience in different kinds of dredging, as well as with the materials removed that differ in consistency and placement options.
Cashman's depth of experience—coupled with our vast fleet of equipment—makes us uniquely qualified to tackle our clients' most demanding dredging and environmental projects. And our history of on-time completions and excellent safety record are benchmarks of Cashman customer satisfaction.
Cashman recognizes its responsibility to improve the communities in which we work, whether projects are performed close to home or in the international market. That is why upholding our values of safety, integrity, accountability, and environmental conservation is paramount at each of our work sites. Our talented crews are implementing sustainable solutions through technology, innovation, and experience to meet all our Clients' dredging needs.
The history of Cashman dates back to the 1970s when Jay Cashman started a construction company in Boston. Throughout the 1980s and 1990s, Jay Cashman, Inc. grew its expertise and resources to become one of the preeminent heavy civil and marine contractors in the Northeast. During this time, Cashman completed smaller dredging projects primarily using mechanical dredges.
In 2003, Cashman Dredging and Marine Contracting Company, LLC was formed to focus more closely on the dredging industry and immediately started its growth into the industry leader it is today. After building its first large dredge with a Liebherr 995 excavator, Cashman completed the $36 million Kill Van Kull 8 contract for the U.S. Army Corps of Engineers (USACE) in New York/New Jersey. During this time, our company also completed numerous smaller navigation and environmental projects for private and public entities, expanding our range of capabilities and ability to complete nearly any project. In 2010, Cashman acquired the trailing suction hopper dredge Atchafalaya, making it one of only five firms in the country able to perform this specialized type of dredging. Today, Cashman Dredging is regarded as a leader in dredging with the equipment and resources to complete nearly any project.
Dredging Project Highlights
- In 2009, General Electric recognized the firm's capabilities when it selected Cashman Dredging to perform the challenging task of removing more than 250,000 cubic yards of PCB-impacted material from the Hudson River during Phase 1 of the project.
- After utilizing the 2010 season to review the results of the 2009 dredging season, General Electric selected Cashman Dredging for Phase 2 of the project for each of the next five dredging seasons (2011-2015) during which more than 2.5 million cubic yards of PCB-impacted material were removed from the Hudson River, and more than 2.6 million tons of backfill, isolation cap, and nearshore restoration materials were placed. The EPA called this multi-year project "a historic achievement."
- Between 2010 and 2013, Cashman Dredging completed two large 50-foot capital dredging projects for the USACE in Newark Bay and the Arthur Kill channel, where more than 5 million square feet of rock were blasted and 1.5 million cubic yards of blasted rock were dredged and placed offshore. During these projects, more than 3.0 million cubic yards of Historic Area Remediation Site (HARS) suitable material were dredged and placed at the HARS, and more than 600,000 cubic yards of non-HARS material were dredged, processed, and placed upland as beneficial re-use material. A large array of equipment was utilized for the project including two large backhoe dredges and clamshell dredges. A custom-designed drilling and blasting barge was also built for the project.
