Marine Construction

Cashman’s water- and land-based solutions strengthen the country’s infrastructure through well-built ports, bridges, and tunnels. Having successfully completed several major complex and challenging marine construction projects, the firm has earned a reputation for safety, excellence and quality.

Whether building piers, revetments, stone structures, or bridges, we apply our marine construction expertise to deliver state-of-the-art solutions. Through our affiliate company, Sterling Equipment, we own and maintain our own fleet of specialized equipment, including dredges, scows, barges, tugs, cranes, and other heavy equipment. This combination of capabilities and resources allows us to act as a single-source provider on complex marine construction projects that would otherwise require multiple subcontractors. This approach reduces our risk as well as that for Owners and Clients.

Recent marine construction work includes the structural repairs to Pier 1 to provide a safe mooring for the USS Constitution at the Charlestown Navy Shipyard in Boston; the land reclamation project at the site of the 2017 America’s Cup in Bermuda; the Marine Commerce Terminal in New Bedford, Massachusetts; or the reconstruction of a major pier in Sunny Point, NC for the U.S. Army Corps of Engineers. Success on large-scale projects such as these has come as a result of expertise, dedication, safe work practices, and efficient execution.

The Cashman Family history in Heavy Civil and Marine Construction dates back to the late 1800s when relatives of Mr. Jay Cashman, the Founder and Chairman of the Cashman Group of Companies, constructed the iconic Provincetown Pilgrim Monument at the tip of Cape Cod. From an early age, Mr. Cashman shared the same enthusiasm, passion, and know-how for the business as his ancestors.

Coming of age through the 1960s and 1970s, Mr. Cashman quickly built a successful track record of performing heavy civil and marine contracting projects throughout the Northeast. Notable work included rebuilding destroyed seawalls and jetties after the Blizzard of ’78 and constructing a new marine facility for the Martha’s Vineyard Steamship Authority.

In 1994, Mr. Cashman founded Jay Cashman, Inc., which represents the primary heavy civil and marine construction entity within the Cashman Group of Companies. Through the 1990s, the firm continued to grow and prosper, executing large-scale heavy civil and marine construction projects including components of such notable regional projects as Boston’s Central Artery “Big Dig” Program; the Deer Island Sewer Treatment Facility; the Spectacle Island Environmental Remediation and Clean-Up; the MBTA South Shore / Greenbush Commuter Rail, and the Fore River Bridge Construction in Quincy, Massachusetts.

Bird Island Ecosystem Restoration, Marion / Buzzards Bay, Massachusetts

The project involves the reconstruction of Bird Island, a 4-acre gravel and boulder-composed island about a half-mile off the coast of Sippican Point and 3 miles from the Marion Town Wharf in Buzzards Bay, Massachusetts. Bird Island is one of only three small islands along the coast of the U.S. that still provides the critical nesting habitat for the endangered Northeast population of Roseate Tern.


USS Constitution Pier 1 Structural Repairs, Boston Navy Yard, Charlestown, Massachusetts

Jay Cashman, Inc., was part of the team awarded this contract for Design/Bid/Build Construction Services for structural repairs to Pier 1, USS Constitution Berth, at the Charlestown Navy Yard in the fall of 2014. The ship entered dry dock in March 2015 for a three-year planned restoration. This pier repair project will provide a safe mooring for the USS Constitution as well as safe visitor access to the ship.


Cross Island, South Basin Land Reclamation, Royal Naval Dockyard, Bermuda

Cashman was selected to be one of the primary contractors responsible for land reclamation efforts for this high-profile project. We were part of the team that completed the first-phase construction of "Cross Island," which will be the home of the Event Village for the 2017 America's Cup, hosted by Bermuda. Cashman proposed an innovative Design-Build option at the bid stage, providing nearly $5.0 million in savings to owner West End Development Company (WEDCo). Through value engineering and ongoing dialogue between the WEDCo and project team, constant evolution of the D-B works is leading to the most efficient, cost-effective, and environmentally sound installation for this high-profile project.


Salem Lateral Pipeline Project, Salem-Beverly, Massachusetts

The goal of this project is to create the pipeline capacity necessary to deliver affordable supplies of clean-burning natural gas from the existing Algonquin Gas Transmission pipeline system to the Salem Harbor Station facility, which is being redeveloped into a natural gas-fired electric-generating plant. Delivers natural gas supplies for the planned Footprint Power Salem Harbor Development, LP Station facility and includes construction of a new metering and flow regulating station within the Salem Harbor Designated Port Area (DPA). Work took place primarily within Beverly Harbor, Collins Cove and the City of Salem, and industrial properties. This effort is one of the latest examples of an industry migrating away from coal towards natural gas as a feedstock for making electricity.


New Bedford Marine Commerce Terminal, New Bedford, Massachusetts

Cashman and our joint venture partner Weeks NB were among the firms contracted to perform dredging and marine construction to provide a multi-purpose facility designed to support the construction, assembly, and deployment of offshore wind projects, as well as handle bulk, break-bulk, container shipping and large specialty marine cargo. The first of its kind in North America, the Terminal was engineered to sustain mobile crane and storage loads that rival the highest load-bearing ports in the nation (loads of 4,000 pounds per square inch).
