What R Zoppo does

R. Zoppo Corp. is a privately held, family-owned heavy civil construction general contractor founded by Rocco Zoppo in 1925 and currently operated by fourth-generation family members Richard and David Zoppo from its headquarters at 160 Old Maple Street, Stoughton, Massachusetts. The company delivers full-service infrastructure construction through five core lines: Underground Utilities (trenching, slip-lining, pipe bursting, and pipe jacking for water/sewer infrastructure), Pumping Stations and Treatment Plants, Bridges (substructure/superstructure work including stone arch, steel/concrete, and precast segmental), Heavy Civil and Roadways (earthmoving, grading, excavation support), and Dams and Flood Control (earth berms, stone/concrete dams, spillways, flood control gates and operating machinery). Differentiated technical capabilities include trenchless utility installation methods that minimize surface disruption, the Cintec Bridge Strengthening System for heritage bridge reinforcement, and 3D laser scanning for dam gate seal dimensional verification.

The company's revenue model is project-based competitive bidding on public works contracts with federal, state, and municipal agencies, with documented individual contract values ranging from $10,000 to $40,000,000. Primary customers include the U.S. Army Corps of Engineers (New England and Baltimore Districts), National Park Service, Massachusetts DOT, Massachusetts Department of Recreation and Conservation, Massachusetts Port Authority, Massachusetts Highway Department, City of Waltham, and private utility Aquaria Water, LLC. Revenue is concentrated in the New England region (Massachusetts, Rhode Island) with selectively documented Mid-Atlantic work (Pennsylvania).

Contract acquisition is pursued through direct competitive bidding on government procurements and direct engagement with private sector clients, with no use of resellers, intermediaries, or ecosystem partners. The company positions itself on four-generation institutional knowledge, self-performance philosophy, and a documented track record of ahead-of-schedule delivery (Sagamore Bridge three weeks early; Ames Street Bridge nine months early) and value engineering (approximately $700,000 in savings on the East Boston/Chelsea Bypass Road). The firm maintains trade affiliations with the Society of American Military Engineers, the Construction Industry Management Association of Massachusetts, and the Construction Institute of Massachusetts, and recruits through a company LinkedIn page; no funding rounds, acquisitions, or external ownership events are disclosed in available records.
