LiRo-Hill

What LiRo-Hill does

LiRo-Hill is a privately held, multidisciplinary architecture, engineering, and construction management (AEC) firm headquartered in Syosset, New York, operating 13 offices across New York, New Jersey, Pennsylvania, Massachusetts, Connecticut, and California. The firm was formed in June 2024 through the merger of The LiRo Group (founded 1984) and Hill Northeast, and today employs more than 1,200 professionals delivering program and construction management, resident/construction engineering and inspection, owner's project management, architecture and sustainable design, civil/structural and MEP engineering, environmental services, GIS/survey, and Virtual Design and Construction Operations (VDCO) — its branded BIM, LiDAR, and 3D-modeling practice. Underlying technology is centered on Building Information Modeling (BIM), laser scanning, GIS, and Python-scripted VDCO tooling, used to coordinate complex public-sector and institutional projects.

The firm generates revenue entirely through project-based professional services fees earned on competitive bids, RFP responses, and long-term program management engagements, with 900+ proposals submitted annually. Its customer base skews heavily toward public-sector agencies — New York State Department of Transportation, Dormitory Authority of the State of New York (DASNY), New York City Department of Parks & Recreation, MTA, NYC Housing Authority, Amtrak, NJ TRANSIT, county and municipal authorities — complemented by healthcare (Stony Brook University Medical Center, MedStar Central), higher education (SUNY), energy (Siemens Energy), and major venue projects (Buffalo Bills Stadium). Distribution runs through direct enterprise sales to government procurement officers, joint ventures with global primes (notably AECOM on Penn Station), and a prequalified subcontractor network.

LiRo-Hill operates primarily in the Northeast public-infrastructure market with selective West Coast expansion, ranked #5 in ENR's 2025 Top 50 Construction Management Firms and recognized with ACEC NY, ASCE, and ENR project-of-the-year awards spanning bridges, transit, parks, resilience, and energy work. The ownership structure is privately held and management-operated, led by founder/Chairman Rocco Trotta (since 1984) and CEO Richard Cavallaro, with no disclosed institutional or PE investor.
