en.Wedoany.com Reported - U.S. heavy civil contractor Halmar International is expanding its influence in tunneling, transportation, and public-private partnership projects from its New York roots to a nationwide scope. Headquartered in Nanuet, New York, the company traces its history back to Halmar Construction, founded in 1962, and has long undertaken transportation and infrastructure projects in New York. In 2017, Halmar joined the ASTM Group, controlled by Italy's Gavio Holding, becoming its U.S. construction arm and gaining the capability to deliver public-private partnership projects and design-build transportation projects.

Kevin Martin, Deputy CEO of Halmar International, stated: "We have never been a contractor that chases easy projects. What sets Halmar apart is that we focus on the most complex, tightly phased projects and figure out how to deliver them in a way that maximizes value, accelerates schedules, and upholds the highest safety and quality standards."

The company's current key tunneling projects include the Second Avenue Subway Phase 2 in New York City and the Potomac River Tunnel Project in Washington, D.C. The design-build contract for the Second Avenue Subway Phase 2 tunnels and structural shells is valued at approximately $1.972 billion, undertaken by Connect Plus Partners, a joint venture between Halmar International and FCC Construction. This project will extend Q Line service north from the 96th Street terminal to 125th Street, covering a total length of approximately 1.5 miles, and construct three new ADA-accessible stations at 106th Street, 116th Street, and 125th Street, expected to serve approximately 110,000 additional daily passengers. The Connect Plus Partners contract encompasses using two large tunnel boring machines to construct twin-bore tunnels 35 to 120 feet beneath Second Avenue, and excavating caverns to build the structural shell for the 125th Street station. Preliminary works and design development are underway, with tunnel boring machines expected to arrive in early 2027.

The Potomac River Tunnel Project in Washington, D.C., part of DC Water's Clean Rivers Project, has a contract value of $819 million, centered on a 5.5-mile-long, 18-foot-diameter deep tunnel. The CBNA-Halmar joint venture is launching two tunnel boring machines from West Potomac Park, one heading north toward Georgetown and one south toward Joint Base Anacostia-Bolling, constructing nine shafts and a series of interception structures along the alignment. As of early 2026, the northbound tunnel boring machine has been assembled in the starter tunnel, with bidirectional boring expected to be in full swing by 2027 and substantial completion around 2029 to 2030.

Leon Jacobs, Executive Vice President of Halmar International, stated: "Halmar has traditionally focused on the Northeast, but with the support of the ASTM Group, the increase in tunneling, transportation, and public-private partnership market opportunities nationwide has led us to expand into the Mid-Atlantic and the West Coast. We see this trend continuing, with strong demand across the country."
