What L.K. McLean Associates, P.C. does

L.K. McLean Associates, P.C. (LKMA) is a privately held New York professional corporation founded in 1950 by Louis K. McLean and headquartered in Brookhaven, NY, with a satellite office in Hicksville. The firm provides planning, design, and construction inspection services across thirteen core disciplines — including highway design, traffic engineering, coastal and marine engineering, airports, building design, MEP engineering, parks and recreation, I/A OWTS wastewater systems, solid waste management, site civil engineering, survey and geospatial services, fish passage design, and resident/construction engineering inspection — to governmental and private clients primarily across Long Island and the New York metropolitan area. The firm employs approximately 80 professionals, including 20+ licensed as professional engineers, land surveyors, architects, or landscape architects, with a stated operating model of active principal involvement on every project.

The firm's core technology stack consists of standard civil engineering and surveying tooling — Synchro traffic analysis software, HydroAction and Fuji Clean wastewater treatment system designs, GIS/mobile data collection, BIM modeling, and conventional surveying instruments — rather than proprietary platforms. LKMA's competitive position rests on regulatory expertise in the Suffolk County and Long Island permitting environment, particularly for nitrogen-reducing I/A OWTS systems (with 100+ completed installations) and federally-funded transportation projects (including a $65M NY-347 reconstruction, a $28M RT 110 bridge widening, and 20+ years of work on Nassau County's computerized traffic signal system covering 250+ signals).

Revenue is generated through project-based professional service contracts and on-call engagements with municipal, county, state, and regional government clients — including Suffolk County DPW, Nassau County DPW, NYSDOT, the Port Authority of NY & NJ, and several Long Island towns — supplemented by a smaller private developer book (e.g., Conifer Realty). Pricing is quoted per project based on scope and complexity and is not publicly disclosed. The firm is principally owned and operated by its executive team led by President & CEO Robert Steele, PE, who assumed leadership in December 2023 following Ray DiBiase's retirement.
