ICSI

What ICSI does

ICSI NY LLC is a privately held, founder-owned full-service commercial construction firm headquartered in Port Washington, New York, serving the New York City metropolitan area. The company was founded by Michael Wersan, a union carpenter and former United States Marine Corps servicemember who progressed from carpenter to project manager to principal, and has been scaled with the addition of construction executive Lenny Wersan, whose four-decade track record includes more than $600 million in delivered projects at properties such as the Plaza Hotel, Waldorf-Astoria, Peninsula New York, and 583 Broadway. The firm positions itself as 'The Problem Solvers,' emphasizing creative problem-solving, attention to detail, and budget discipline on dense Manhattan job sites.

The company offers three core services (Consulting, Construction Management, and General Contracting) delivered as an integrated end-to-end capability from initial concept through final execution, with the general contracting function managing all subcontractors and suppliers in-house. These services are applied across three primary industry verticals: Commercial & Retail, Hospitality, and Food & Beverage. Named hospitality and F&B projects include Archer Hotel (38th Street), Palace Hotel (Madison Avenue), Curio Martinique (32nd Street), Press Club Grill (Broadway), Montauk Blue, and ARLO NoMad (31st Street), evidencing concentration in boutique and lifestyle hotel operators as well as culinary establishments. The technology stack is conventional construction project delivery with no disclosed proprietary software, AI/ML features, integrations, APIs, or mobile applications.

ICSI's business model is project-based, one-time commercial contracting engagements priced via custom quotes rather than disclosed rate cards. The go-to-market motion is direct enterprise field sales targeting property owners, developers, architects, and engineering teams, supported by a professional website portfolio and an active employment portal. Revenue is not publicly disclosed, there are no funding rounds, the company is bootstrapped via organic growth, and there is no parent company or institutional investment. The firm holds no disclosed patents, trademarks, awards, or formal partnerships, and operates exclusively within the USA without any stated global ambitions.
