Posillico

What Posillico does

Posillico Inc. is a privately held, four-generation family-owned heavy civil construction company headquartered in Farmingdale, New York, operating across New York Metro, Long Island, New Jersey, the Mid-Atlantic, Texas, and Florida. The company delivers infrastructure projects through ten service lines: Civil, Design-Build, Environmental, Paving, Utilities, Wastewater, Materials, Marine, UHPC (Ultra-High Performance Concrete), and a Wash Plant for contaminated soil. Notable technical capabilities include the Giken Silent Piler for non-vibratory press-in sheet pile installation along sensitive urban waterways, thermal desorption treatment for manufactured-gas-plant contaminated soils, an in-house contaminated soil washing facility, and GPS-guided grading equipment across the fleet. The company maintains owned materials production (asphalt and aggregates), permitted environmental handling and disposal facilities, and a marine sub-brand (Breakwater Marine) for dredging and barge work.

Posillico generates revenue primarily through competitive bidding on unit-price and lump-sum contracts for public agencies (state DOTs, NYC DOT, LIRR, school construction authorities, municipal clients) and negotiated awards for private developers, utilities (National Grid, Con Edison, PSE&G), and institutional clients (healthcare systems). Contract values range from approximately $250,000 to over $300 million, with marquee wins including the Belt Parkway Bridges ($380M), Van Wyck Expressway ($326.7M), Atlantic Yards ($301M), Bruckner Viaduct ($205.9M), and Alexander Hamilton Highbridge ($138.78M). The company supports direct enterprise field sales alongside a subcontractor prequalification channel, and is positioned to capture demand from the federal infrastructure spending cycle, particularly after its 2022 acquisition of Martins Construction expanded Mid-Atlantic heavy highway and bridge capacity. Revenue, financials, and headcount trends are not publicly disclosed, limiting external visibility into current scale, but the breadth of regions, service lines, and contract values is consistent with a mid-to-large regional heavy civil contractor.
