What Trevcon Construction does

Trevcon Construction is a privately held, family-owned marine contractor founded in 1987 by Ronald Treveloni, Sr. and now led by his son Ronald Treveloni, Jr. Headquartered in Liberty Corner, New Jersey, with a secondary office in Manhattan and a six-acre heavy marine operations facility (T-Port) in Elizabeth, NJ, the company specializes in marine and underwater construction, dredging, and offshore services across the New York–New Jersey tri-state region. Its core capabilities include pile driving, pier and wharf reconstruction, bulkhead stabilization, bridge fender systems, ferry terminal construction, and offshore wind cable landfall — executed with union dockbuilders, commercial divers, and a specialized fleet of cranes and barges. The company's proprietary Trevcon-Veyor, a patented flexible barge with a partially submerged conveyor system, enables reinforcement stone placement in previously unreachable underwater locations beneath piers over 100 feet long.

Trevcon generates revenue primarily through project-based construction contracts delivered under design-bid-build and design-build formats with government agencies (NYC DSNY, NYC DOT, Port Authority of NY/NJ, NJ DOT, NYC MTA, NY Thruway Authority) and private enterprise clients (Electric Boat, Global Container Terminals, Orsted/Jan De Nul, Equinor, Fordham University). Pricing is determined through competitive public bidding rather than disclosed rate cards, and individual contract values frequently exceed $100 million, including a $181 million joint venture with Skanska for the NYC DSNY 91st Street Marine Transfer Station. The company pursues complex marine work through joint ventures with multinational primes (notably Skanska on multiple projects) and as a subcontractor on energy infrastructure (offshore wind cable landfall).

The company has scaled to 250+ employees and built a three-decade track record on high-profile waterfront projects including South Street Seaport, Brooklyn Bridge Park, Pier 25, Little Island, Google Pier 57, and the Mario Cuomo Bridge foundation testing — establishing incumbency advantages with regional government clients. Recent strategic activity indicates active diversification into offshore wind (Sunrise Wind, South Brooklyn Marine Terminal) and naval/defense infrastructure (Electric Boat Groton expansion for the Columbia-class submarine program), supported by capacity expansion at the T-Port facility.
