Heavy Civil / Infrastructure

At Cashman, we understand that cities and communities, the government and military, and many federal and municipal agencies depend on modern, reliable infrastructure to remain competitive and safe in the global market. It is our goal to provide innovative solutions that minimize the risks and costs associated with improving local infrastructure – on, under, and over water and land.

Cashman builds infrastructure that is vital to the economic development of communities around the United States and beyond. Our engineers and operators build quality structures and integrate them into the surrounding environment. We ensure our clients are able to make the most informed and beneficial decisions possible by working closely with owners and engineers during pre-construction phases. Working across a wide range of markets, we ensure client goals and community needs are met. The firm specializes in the building and demolition of numerous land- and water-based structures including:

  • Bridges / Tunnels
  • Roadways
  • Railways
  • Industrial Facilities
  • Piers
  • Bulkheads
  • Flood Control
  • Stone Structures

We combine years of experience with the considerable resources of The Cashman Companies to complete complex projects. We use a collaborative approach on our projects with the goal of maximizing returns for clients, who include federal, military and public agencies, private developers, and general contractors. Cashman also owns and maintains a fleet of specialized equipment including excavators, cranes, dredges, scows, barges, tugs, and other heavy equipment so that we can achieve results quickly, and in any environment. Our comprehensive project plans are designed to achieve client goals, minimize disruption, comply with environmental regulations, and—most importantly—ensure that everyone involved at our work sites goes home safe each day.

Cashman’s history in construction dates back to the late 1800s when Jay Cashman’s relatives constructed the iconic Provincetown Monument at the tip of Cape Cod. Much of the firm’s early civil work focused on local major projects related to Greater Boston and Boston Harbor. These include the historic heavy civil construction work we achieved on Boston’s Central Artery and Tunnel (CA/T) project; the extraordinary remediation and land reclamation work on Spectacle Island in Boston Harbor; the Harbor clean-up with the effluent outfall pipe work nine miles out into Boston Harbor; and the extension of the MBTA’s commuter rail through multiple South-Shore communities.

In the past decade, Cashman has continued to complete challenging heavy civil and marine construction projects and has expanded its service offerings to include disaster-related debris removal.

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.


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.


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).


Gowanus Canal – Former Citizens MGP Site Pilot Test Program, Brooklyn, New York

In 2014, Cashman performed a Pilot Study to evaluate different sheet pile designs and effects on infrastructure along the Gowanus Canal for future remediation work. Information gained during the Pilot Study was used to determine best remediation methods for the former Metropolitan and Fulton Manufactured Gas Plant (MGP) sites.


82nd Avenue Bridge Replacement and Roadway Improvement, Vero Beach, Florida

On behalf of the South Eastern Indian River County, Cashman replaced the bridge on 82nd Avenue over the Indian River Farms Water Control District Lateral "D" Canal at 4th Street in Vero Beach. There were roadway improvements made on both the north and south side of the bridge, for a total of 800 feet of construction.
