What Lanmark Group, Inc. does

Lanmark Group, Inc. is a Brooklyn, New York-based full-service general contracting firm founded in 2005 by President Eleftherios Kougentakis. The company plans, manages, and delivers construction and renovation projects across the full project lifecycle — pre-construction (estimating, site logistics, M/WBE participation, scheduling, buyouts), construction management (on-site supervision, MEP coordination, document and cost control), and post-construction (punchlist, close-out, O&M manuals, warranty). It serves both public and private sector clients, with the public sector as its primary market: the disclosed portfolio includes work for the New York City Department of Design and Construction, the Dormitory Authority of the State of New York, the NYC Housing Authority, the Port Authority of New York and New Jersey, the NYC School Construction Authority, NYC Health + Hospitals, the MTA (NYC Transit and Long Island Railroad), the NYC Department of Correction, and the City University of New York.

Lanmark does not operate a proprietary technology platform; its core capability is general contracting and construction management services delivered by a small in-house team (11-50 employees) supported by an experienced subcontractor network. Differentiators cited are 35+ years of construction experience from the founder, LEED-Accredited Professionals, OSHA-certified personnel with a strong safety record, and hands-on senior management involvement on every project.

The business model is project-based revenue earned through competitive bidding on public-sector construction contracts, with contract values ranging from $268K (e.g., a COVID-19 testing facility) to $35M (Rikers Island GC requirement contracts). The firm is privately held by the founder, with no disclosed external investors, parent company, or funding rounds. Geographic reach is concentrated in the New York City metropolitan area across all five boroughs and surrounding New York State regions.
